1. Primeforge
Primeforge is an email infrastructure solution designed specifically for cold outreach. Unlike typical email providers, it prioritizes protecting and improving sender reputation through automated technical setups and strategic infrastructure decisions, all aimed at boosting deliverability rates.
Sender Reputation Monitoring Capabilities
Primeforge takes a proactive approach to tackling deliverability challenges. Instead of relying on traditional dashboards, it safeguards sender reputation by integrating with Google Workspace and Microsoft 365 mailboxes. These platforms inherently carry higher trust levels from major email providers.
One standout feature is ESP matching, which ensures that your emails originate from the same provider as your recipient. For example, emailing a Gmail user from a Google Workspace mailbox increases the likelihood of landing in their inbox.
By focusing on maintaining strong domain and IP reputations, Primeforge helps users avoid spam filters. This is especially critical given that 45% of cold emails in 2025 fail due to technical missteps, not poor content. This kind of proactive management ensures smoother authentication and better email performance.
Automated DNS/Authentication Setup (SPF, DKIM, DMARC)
Primeforge simplifies email authentication by automating the setup of SPF, DKIM, and DMARC records based on industry standards. This feature is ideal for teams without technical expertise or those looking to save time on manual configurations.
Correctly setting up SPF, DKIM, and DMARC is essential for building trust with email providers. These protocols ensure your emails pass security checks and make it to the inbox instead of being flagged as spam.
This automation addresses a major issue in the industry. According to Validity's 2024 Email Benchmark, 21% of B2B emails fail to reach inboxes due to poor domain or IP configurations. By automating these tasks, Primeforge helps users achieve inbox placement rates of 85% or higher, with the potential to exceed 90%.
US-Based Infrastructure and IPs
Primeforge provides US-based IP addresses for all domains and mailboxes, making it particularly advantageous for businesses targeting the North American market. US-based IPs often receive better reputation scores from major email providers, which can improve deliverability for campaigns aimed at recipients in the same region.
The platform is built for scalable and reliable email delivery in the U.S. market. Many users have reported excellent results, including Rahul Lakhaney, Former VP at Gartner and now CEO of Enrich.so and Maximise, who shared:
"I've been using a couple of other email infra forges for over a year and have been pretty impressed with deliverability... Stellar deliverability on Salesforge and spam tests always come back green! Excited to spin up some Outlook accounts soon also."
Pricing (in USD/Month)
Primeforge offers a competitive pricing model, charging $3.50–$4.50 per mailbox per month. This makes it an affordable option for teams looking to scale their outreach efforts without breaking the bank.
When compared to alternatives like Mailreach ($59/month), Infraforge ($49/month), or Warmup Inbox ($49/month), Primeforge stands out as a cost-effective solution.
For enhanced performance, Primeforge can be paired with other tools in the Forge Ecosystem, such as Mailforge or Infraforge. Users are also encouraged to use email deliverability monitoring tools like Warmup Inbox for a comprehensive health check of their mailboxes.
2. Mailforge
Mailforge is a key component of the Forge Ecosystem, designed specifically for cold email outreach. Unlike traditional email platforms like Gmail or Outlook, Mailforge was created by experts in cold outreach to ensure better deliverability and safeguard sender reputation.
Keeping an Eye on Sender Reputation
Mailforge offers tools to monitor sender reputation with real-time stats on opens, replies, and bounces. It operates using a shared IP pool, leveraging an established reputation to improve email deliverability right out of the gate, as opposed to starting from scratch with a single IP address. The platform also helps maintain clean contact lists by limiting interactions with unverified or unresponsive leads. With an impressive 4.8 out of 5 rating on G2, users frequently highlight its fast and efficient customer support, which addresses deliverability concerns in minutes.
Automated Setup for SPF, DKIM, and DMARC
One of Mailforge's standout features is its ability to automate DNS and authentication setups, including SPF, DKIM, and DMARC, significantly speeding up the process. By simply updating their domain nameserver, users can let Mailforge handle all the technical configurations, reducing setup errors and ensuring proper authentication.
Karlo Binda, the Founder of Leadsnack.co, shared his experience:
"Procedures that usually took hours (setting DKIM, SPF, etc. records) for multiple domains, now take a few minutes. Mailforge is also cost-efficient since you spend per mailbox ~3 times less than with Gmail."
The platform also includes SSL and Domain Masking features, which enhance security and privacy by protecting your domain and increasing trust with email providers.
Pricing Breakdown (in USD/Month)
Mailforge offers a cost-effective solution for email infrastructure. For example, setting up 200 mailboxes takes only 5 minutes and costs $484 per month - a significant savings compared to the $1,680+ monthly cost and 2-hour setup time with Google Workspace, or $1,200+ with Microsoft 365. Mailforge users pay around $2–$3 per mailbox, compared to $6–$8 with traditional providers.
| Platform | Setup Time | Monthly Cost for 200 Mailboxes |
|---|---|---|
| Mailforge | 5 minutes | $484 |
| Google Workspace | ~2 hours | $1,680+ |
| Microsoft 365 | ~2 hours | $1,200+ |
These cost and time savings make Mailforge a highly efficient alternative to legacy email platforms.
Isabella L., Founder of Let's Fearlessly Grow, praised the platform, saying:
"The simplicity and the automation in the buying process of domains, DNS setting, inbox creation, forwarding, etc. Everything in one place... my results had been great since using Mailforge!"
Additionally, Mailforge integrates seamlessly with Salesforge and other email-sending tools, making it a flexible and powerful addition to your outreach strategy.
3. Infraforge
Infraforge builds on the automation and reputation management features of Primeforge and Mailforge but is tailored for advanced users who need dedicated solutions. It provides private email infrastructure for cold outreach, giving users full control over their sender reputation. Unlike shared infrastructure services, Infraforge offers dedicated resources and advanced monitoring tools, ensuring complete visibility into email performance.
Sender Reputation Monitoring Capabilities
Infraforge goes beyond basic open and click tracking with its deliverability monitoring features. It sends alerts if your domain or IP ends up on major blacklists . It also tracks inbox placement - whether emails land in the Primary, Promotions, or Spam folder - and evaluates domain health across multiple brands. With its centralized dashboard, users can manage domain reputation, warmup processes, and IP protection all in one place, reducing the need for multiple tools.
Automated DNS/Authentication Setup (SPF, DKIM, DMARC)
Setting up email authentication protocols like SPF, DKIM, and DMARC can be time-consuming and technical, but Infraforge automates the entire process. This reduces deployment time from hours to just minutes, making it accessible even for teams without technical DNS expertise . Proper authentication not only boosts email security by reducing phishing by 90% and tampering by 30%, but Infraforge also enhances privacy with SSL and Domain Masking features, safeguarding your primary domain's reputation .
US-Based Infrastructure and IPs
With dedicated IP addresses and multi-IP provisioning, Infraforge ensures that your email reputation remains unaffected by other users. The platform also includes IP rotation, which helps distribute sending volume across multiple addresses, lowering the risk of any single IP being flagged. This is particularly valuable for high-volume senders focused on maintaining consistent deliverability .
Pricing (in USD/Month)
Infraforge uses a slot-based pricing model, offering flexibility for teams with different mailbox requirements. Plans start at $17 per month (billed annually) for 10 mailbox slots and go up to $651 per month for 200 slots, making it suitable for both small teams and high-volume operations. The slot system allows users to activate or deactivate mailboxes without changing their plan, as pricing is based on total capacity rather than active usage. Annual billing includes a discount equivalent to two months free.
| Feature | Price |
|---|---|
| Base Plan | $17/month (10 slots, annual billing) |
| High-Volume Plan | $651/month (200 slots) |
| Dedicated IPs | $99 per IP address/month (billed quarterly) |
| SSL & Domain Masking | $2/domain/month (quarterly) or $6/domain/year |
Additional services include domain registration at $70 per year and consulting sessions priced at $500 for two one-on-one expert sessions. Bulk users can benefit from discounted rates as low as $2.50 per mailbox.
Infraforge highlights its value with this statement:
"Our subscription prices include both the automated DNS setup and ongoing hosting and maintenance of your mailboxes".
This pricing structure is ideal for teams that need scalable, high-control solutions for email deliverability.
4. Salesforge
Salesforge is a cold email platform trusted by over 10,000 businesses. Designed for sales leaders, agencies, and recruiters, it focuses on protecting email deliverability while staying aligned with the latest updates and trends in email service providers (ESPs). Below, we explore how Salesforge helps maintain a strong sender reputation.
Sender Reputation Monitoring Capabilities
Salesforge prioritizes sender reputation with proactive tools like contact validation. This feature allows users to validate their email contacts directly from the dashboard, reducing the risk of bounces and spam complaints that could damage domain credibility. The platform’s integration with Warmforge provides access to Google Postmaster and other deliverability data sources, helping users identify and resolve issues early. Many users report improved lead quality and higher response rates when sending smaller, more targeted email batches. Beyond monitoring, Salesforge simplifies the technical aspects of email setup to enhance deliverability.
Automated DNS/Authentication Setup (SPF, DKIM, DMARC)
Salesforge takes the complexity out of technical setups by automating SPF, DKIM, and MX record configurations. This automation ensures a smooth start for users, while free warm-up services help establish a strong sender reputation from day one.

6. Warmup Inbox
Warmup Inbox is a cost-effective solution designed to help you monitor and improve your email sender reputation. By simulating real user interactions through genuine inboxes, it helps ensure your emails avoid spam folders and blacklists, building a strong reputation from the ground up.
The platform uses a Reputation Score system, rating sender health on a scale from 0 to 10. It compares your score against community benchmarks and provides tailored recommendations, giving you a clear plan to improve your email deliverability.
Sender Reputation Monitoring Capabilities
Warmup Inbox goes beyond basic tracking by offering detailed monitoring tools. It keeps an eye on major email blacklists and sends immediate alerts if your Reputation Score drops. This feature allows you to halt campaigns before further damage occurs.
The platform also addresses common challenges like avoiding spam folders and Gmail's Promotions tab, significantly improving email deliverability. Users have reported that Warmup Inbox can double open rates, making it especially useful for cold outreach campaigns.
For new email accounts, the platform recommends a 45–90 day warmup period before launching larger campaigns. It also stresses the importance of ongoing warmup efforts to maintain a strong sender reputation for future outreach.
Automated DNS/Authentication Setup (SPF, DKIM, DMARC)
Warmup Inbox simplifies the setup of essential email authentication protocols like SPF, DKIM, and DMARC. It provides step-by-step guidance for configuring these settings on both Google and Microsoft accounts.

8. Validity (formerly Return Path)
Validity, previously known as Return Path, stands out in the email deliverability space with its Everest reputation monitoring platform and BriteVerify email verification service. The company’s Everest solution is designed for tracking sender reputation, while BriteVerify ensures email list accuracy.
What sets Validity apart is its strong integration with major mailbox providers and its Sender Certification program. For senders using dedicated IP addresses to send over 100,000 emails monthly, the program offers preferential treatment with top mailbox providers. Shared IP addresses may also qualify for Certification for Mandated Mail.
Sender Reputation Monitoring Features
The Everest platform gives users a clear view of their sender reputation by tracking metrics like IP reputation, domain reputation, and authentication status across major mailbox providers. Users can monitor spam complaint rates, bounce rates, and engagement levels in real time through detailed dashboards. Additionally, Everest helps pinpoint issues like authentication failures caused by automatic forwards or spoofing attempts, offering insights to improve email deliverability.
"Validity has helped us get our deliverability figures back on track and we are delighted with the results. It has allowed us to identify elements of our program that were hindering our reputation and make changes without negative consequences."
– Mads Neble, Director CRM & Online, Boozt
For email list validation, BriteVerify boasts an impressive 95.19% accuracy rate, as reported by ListCleaningAdvice.
Beyond reputation metrics, Validity also focuses on streamlining email authentication processes.
Simplified DNS/Authentication Setup (SPF, DKIM, DMARC)
Everest makes implementing DMARC policies easier - a much-needed capability, considering 84% of domains lack DMARC records, and 68% of those with records use a "none" policy. The platform monitors all email-sending sources on your behalf and provides detailed reports on SPF, DKIM, and DMARC statuses. This allows users to transition seamlessly from a "policy=none" approach to stricter enforcement.
Validity’s structured approach to DMARC implementation includes:
- p=none: No action taken; emails are delivered as usual.
- p=quarantine: Emails are sent to spam or junk folders.
- p=reject: Emails are rejected or bounced outright.
Before enabling DMARC enforcement, Everest ensures SPF and DKIM are properly configured, reducing the risk of disruptions.
Pricing (in USD/Month)
Validity offers tiered pricing for its services, catering to businesses of various sizes and needs:
Everest Platform:
- Elements: $20/month – Basic reputation monitoring
- Elements Plus: $525/month – Advanced monitoring and reporting

- 10,000 verifications: $80 ($0.008 per verification)
- 50,000 verifications: $325 ($0.0065 per verification)
- 250,000 verifications: $1,250 ($0.005 per verification)
- 500,000 verifications: $2,250 ($0.0045 per verification)
"People are spending hundreds of thousands, if not millions, of pounds on their email programs. With Validity, you're paying a small fraction of that to protect these investments and protect one of your key marketing channels. I think you'd be crazy not to consider it."
– Jonathan Kirk, CRM and Design Manager, Ice Travel Group
While the pricing might seem higher than other tools, the benefits of Validity’s Sender Certification program and its strong relationships with mailbox providers can make it a worthwhile investment for businesses sending large volumes of emails and aiming for improved inbox placement.
9. GlockApps
GlockApps stands out among sender reputation tools for its focus on detailed technical diagnostics. Unlike platforms that stick to basic monitoring, GlockApps dives deep into areas like DNS settings, content triggers, and blacklist statuses. It's particularly useful for businesses that need a thorough understanding of their email authentication setup and sender reputation.
As Praduman Singh, Senior Sales Development Representative at Zimetrics, puts it:
"GlockApps provides in-depth diagnostics to help pinpoint the exact cause and provides specific actions to resolve it. It goes beyond surface-level checks and really dives into technical details like DNS settings, content triggers, and blacklist monitoring."
Sender Reputation Monitoring Capabilities
GlockApps offers powerful tools to monitor domain and IP reputation from multiple angles. It tracks your domain and IP addresses against more than 50 industry blocklists, delivering a wide range of insights to help identify potential deliverability threats. The platform provides detailed reports that include Sender Score metrics, blacklist records, and inbox vs. spam folder placement rates. These features make it easier to evaluate the performance of every IP involved in sending your emails - a critical factor since sender reputation is the backbone of email deliverability.
Additionally, GlockApps provides actionable recommendations to improve deliverability. Alex Arnaut, CEO at GlockApps, emphasizes:
"GlockApps tools empower you to maintain high email deliverability and effectively protect sender reputation."
The platform also keeps an eye on spam complaint rates, alerting users if complaints exceed 0.1% - a sign that content or targeting strategies may need adjustment.
Automated DNS/Authentication Setup (SPF, DKIM, DMARC)
GlockApps includes advanced DMARC tools that simplify setup and compliance. Users can create records, analyze reports, and verify domain alignment, helping them achieve 90–100% DMARC compliance before enforcing a "p=reject" policy. This feature is especially critical given the risks of email-based threats - 94% of malware originates from email, and phishing accounts for 80% of security incidents, costing approximately $17,700 every minute.
With its technical expertise, GlockApps offers a flexible pricing structure to accommodate different business needs.
Pricing (in USD/Month)
GlockApps offers a tiered pricing model that caters to businesses of various sizes:
- Free: $0/month
- Essential: $59/month ($708 annually)
- Growth: $99/month ($1,188 annually)
- Enterprise: $129/month ($1,548 annually)
Custom plans are available for businesses with higher email volumes. Note that all prices are exclusive of taxes.
The platform enjoys strong user satisfaction, with ratings of 4.8 out of 5 stars on Capterra, Software Advice, and GetApp, based on 37 reviews each. However, some users feel the pricing may be steep for occasional users. Alternatives like Mailreach, which offers spam testing starting at $9.60/month, might be more budget-friendly for these users.
Despite the higher costs, GlockApps delivers value through its detailed technical analysis and troubleshooting tools, helping users address complex deliverability challenges before they affect email campaign performance.
10. Postmaster Tools (Gmail/Yahoo)
Gmail and Yahoo Postmaster Tools give you a direct line to understanding how major email providers evaluate your sender reputation. Unlike third-party tools, these free resources offer insights straight from the source. Gmail's Postmaster Tools, for example, provides a detailed look at how the world’s largest email provider assesses your email-sending practices.
As Tom Corbett from Iterable puts it:
"Google Postmaster Tools is a free resource that gives senders direct access to feedback on how Google views their sending practices."
Surprisingly, about 70% of email senders don’t take advantage of these tools, missing out on valuable feedback from providers that control a significant share of email delivery.
What Postmaster Tools Monitor
Postmaster Tools go beyond basic metrics, offering a deep dive into the factors that influence your email deliverability.
Gmail’s Postmaster Tools feature eight dashboards, each tracking key aspects of sender reputation. These include domain reputation, IP reputation, spam rate, authentication results, encryption compliance, delivery errors, and feedback loops. The dashboards use a red-to-green color scale, making it easy to gauge your reputation at a glance.
One standout feature is the Spam Rate dashboard. It tracks the percentage of your emails that make it to Gmail’s inbox but are flagged as spam. Gmail calculates this by comparing the number of spam-marked emails against total inbox deliveries. This metric is critical because Gmail has set a strict complaint rate threshold: senders exceeding 0.3% risk being blocked, while staying below 0.1% is considered best practice.
Recently, Google introduced a "Compliance Status" section in its updated V2 dashboards. This new feature offers a more user-friendly and accurate view of sender data compared to the older V1 dashboards.
It’s important to note that these tools are geared toward high-volume senders. You’ll need to send at least 5,000 emails to Gmail in a 24-hour period for the data to be meaningful. Also, the insights provided are historical, not real-time, so they’re best used for retrospective analysis.
Here’s a breakdown of key capabilities:
- Domain and IP reputation tracking to monitor how your emails are perceived.
- Authentication checks for SPF, DKIM, and DMARC to ensure your emails pass validation.
- Delivery error analysis to identify rejection reasons and temporary failures.
- Encryption compliance monitoring, especially important since Gmail requires TLS encryption starting December 2023.
- Feedback loop data to understand user complaints and spam reports.
Pricing (in USD/Month)
One of the best parts? Google Postmaster Tools is completely free, making it accessible for businesses of all sizes, from startups to large enterprises. Yahoo’s postmaster tool is also free, adding even more value to your sender reputation monitoring strategy.
The combination of no cost and direct insights from providers makes these tools essential for anyone serious about email deliverability. Pairing Postmaster Tools with automated platforms like Primeforge can help you take your email campaigns to the next level.

Add in US-based IP addresses, and it’s a strong choice for targeting North American markets.
For startups or those on a tight budget, Mailforge delivers excellent value at $2–$3 per mailbox. For example, managing 200 mailboxes would cost around $484/month - a bargain compared to the $1,680 for Google Workspace or $1,200 for Microsoft 365. Despite the lower price, Mailforge still offers automated DNS setup, saving time and effort.
When it comes to automation, tools like Primeforge and Mailforge simplify setup with automatic SPF, DKIM, and DMARC configuration, cutting setup time from hours to just minutes. In contrast, GlockApps and Validity Everest require manual DNS configuration, which can be more time-consuming.
For enterprise users with complex needs, Infraforge and Validity Everest are top contenders. Both offer advanced features like multi-IP provisioning, API access, and competitor benchmarking, making them ideal for large-scale operations.
It’s worth noting that Postmaster Tools is only effective for senders dispatching 5,000+ emails per day. For lower-volume campaigns, tools like GlockApps or Mailreach are better suited.
Ultimately, the right choice depends on your outreach goals, technical expertise, and budget. Whether you're a startup looking for affordability or an enterprise needing advanced customization, there’s a tool tailored to your needs.
Conclusion
Keeping a close eye on sender reputation isn't just a technical task - it's the backbone of effective email outreach in the US. Industry leaders emphasize its importance time and again.
As Ehtisham Hussain from WordStream explains:
"Email sender reputation is the unseen gatekeeper determining whether your emails land in inboxes or disappear from inboxes. Understanding and managing email sender reputation is essential to maximize deliverability and engagement."
The numbers speak for themselves. Email marketing boasts an average ROI of $42 for every dollar spent. Even minor improvements in email deliverability can lead to noticeable gains in campaign performance and return on investment. For high-volume senders targeting the US, this is even more crucial, as they often face greater challenges with deliverability. These tangible benefits highlight why ongoing monitoring of sender reputation is a must.
Enter Primeforge, a solution tailored for the unique challenges of cold outreach in the US. Its ability to match email service providers - like sending from Google Workspace to Gmail or Microsoft 365 to Outlook - creates trust signals that help emails land in the inbox. Plus, automating technical configurations eliminates the hassle of manually managing DNS records, giving you more time to focus on crafting engaging campaigns.
In a market where deliverability rates dipping below 95% can raise red flags, choosing the right tools and strategies for monitoring your sender reputation is essential for long-term success.
FAQs
What is sender reputation, and why is it important for email deliverability?
Sender reputation is a score that Internet Service Providers (ISPs) use to evaluate your email-sending habits. This score plays a critical role in determining whether your emails make it to recipients' inboxes or are flagged as spam.
Maintaining a solid sender reputation is key to achieving higher email delivery rates. It builds trust with ISPs and ensures your messages reach your audience effectively. For businesses, keeping an eye on this score is vital - it safeguards brand credibility, boosts customer engagement, and supports the success of email marketing campaigns.
What features should you consider in a sender reputation monitoring tool, and how do they affect email deliverability?
When selecting a sender reputation monitoring tool, prioritize features such as sender score tracking, bounce and complaint rate analysis, spam complaint monitoring, blacklist status checks, and authentication protocol validation. These metrics are essential for gauging how email providers view your messages and ensuring they make it to your recipients' inboxes.
Keeping an eye on these elements allows you to spot and address issues that could lead to your emails being marked as spam or blocked altogether. This not only improves inbox delivery but also increases engagement rates and preserves your sender reputation - both crucial for running effective email campaigns. Tools like Primeforge, which specialize in customized email infrastructure solutions, can further support these efforts by offering dependable mailboxes and simplified DNS configurations to boost deliverability.
How do automated DNS setup and US-based IP addresses enhance email deliverability for businesses targeting North America?
Automating your DNS setup takes the hassle out of properly configuring critical email authentication records like SPF, DKIM, and DMARC. These records play a key role in verifying the authenticity of your emails, safeguarding against spoofing attempts, and boosting your email deliverability by ensuring your messages are treated as legitimate by inbox providers.
Additionally, using IP addresses based in the United States can improve email deliverability within North America. This alignment with local inbox providers' preferences helps lower the risk of your emails being marked as spam, increasing the likelihood that they’ll land in your recipients’ inboxes.
