How To Reduce The Risk Of Email Infrastructure Burn
Email infrastructure burn can ruin your email campaigns by damaging your sender reputation. This happens when ISPs flag your domains, IPs, or mailboxes as spammy, often due to overuse, poor setup, or bad management. The result? Emails land in spam folders - or don’t get delivered at all.
Here’s how to prevent it:
- Warm-Up Gradually: Start small and increase email volume over time to build trust with providers.
- Clean Your Email Lists: Remove invalid or inactive addresses to lower bounce rates (keep it under 1%).
- Authenticate Your Emails: Set up SPF, DKIM, and DMARC records to verify your identity.
- Monitor Metrics: Track deliverability, bounce rates, and spam complaints to catch issues early.
- Use Tools: Platforms like Primeforge automate warm-up, DNS setup, and reputation management.
How to Maintain Sender Reputation for Better Deliverability
Your sender reputation plays a key role in determining whether your emails land in inboxes or get flagged as spam. Essentially, it's your email deliverability score. To keep this score high, you'll need a strategic approach that combines gradual warm-up protocols, clean email lists, and smart automation tools like Primeforge. Let’s dive into each of these steps.
Setting Up Warm-Up Protocols and Gradual Volume Increases
Warming up your email account is all about building trust with email service providers (ESPs). By gradually increasing your sending volume, you signal to ESPs that your account is legitimate. For example, tools like SpamAssassin flag emails from domains less than 14 days old as suspicious, so rushing your email activity can backfire fast.
A structured warm-up plan typically unfolds in three phases:
| Phase | Timeline | Recipients | Daily Volume | Primary Goal |
|---|---|---|---|---|
| Initial Trust Building | Week 1 | Most engaged contacts | 10–20 emails | Generate opens, clicks, and replies |
| Gradual Expansion | Weeks 2–3 | Moderately engaged contacts | Double volume weekly | Scale while maintaining engagement |
| Full Volume Scaling | Week 4+ | Complete target audience | Ramp to target volume | Sustain reputation at normal levels |
For small-scale campaigns (under 20 emails daily), manual warm-up works fine. But for larger campaigns, automated tools are essential. For instance, starting with 30–50 emails per day and gradually increasing to 100–150 over three to four weeks is a common approach.
During this process, focus on engagement rather than sheer volume. Respond to replies promptly, as this shows ESPs that your emails are part of real conversations. Personalize your emails to encourage responses and ask recipients to mark your messages as safe if they land in spam. Avoid sudden spikes in email volume, like jumping from 5 to 50 emails overnight, and maintain consistent sending patterns.
Cleaning Email Lists and Proper Segmentation
A clean email list is critical for maintaining strong deliverability metrics. Major providers like Google, Yahoo, and Microsoft require bulk senders to keep spam complaint rates below 0.3% as of February 2024. Yet, many marketers overlook this essential step.
Start by ensuring you have explicit consent from your recipients. Use a confirmed opt-in (double opt-in) process to verify that subscribers genuinely want your emails. This reduces the risk of fake sign-ups and future complaints.
Inactive subscribers can hurt your metrics, but don’t rush to remove them. Instead, try a "win-back" campaign to re-engage them before deciding to clean them from your list. At the same time, proper segmentation can make a big difference. By dividing your audience into smaller groups based on behavior, interests, or engagement levels, you can send more relevant content, which boosts engagement and reduces spam complaints.
Make sure unsubscribing is simple. As email marketing expert Tracie Pang points out:
"Some spam complaints could come from not having an easy unsubscribe. You should have a one-click unsubscribe button to comply with Gmail and Yahoo, but also because it's the best way to make sure someone isn't just marking you as spam out of frustration."
With a clean and segmented list, you’re in a strong position to use automation tools to further protect your sender reputation.
Using Primeforge to Automate Reputation Management
Primeforge simplifies reputation management by automating critical tasks like warm-up protocols and list maintenance. It’s designed for Google Workspace and MS365 mailboxes, using US-based IP addresses optimized for cold outreach.
The platform significantly reduces setup time - from over 24 hours to just 30 minutes - and cuts costs by up to 46%. It also handles the technical setup for DMARC, SPF, DKIM, and custom domain tracking, eliminating the need for manual DNS configuration. Bulk DNS updates make it easy to manage multiple domains at once.
Rahul Lakhaney, former VP at Gartner and current CEO at Enrich.so, shared his experience with Primeforge:
"I've been using a couple of other email infra forges for over a year and have been pretty impressed with deliverability. Now I added Google mailboxes and been using them for months as one of the early adopters to spread the load of 10K+ emails/day over to more ESPs. Stellar deliverability on Salesforge and spam tests always come back green!"
Primeforge also supports ESP matching, which ensures that your emails are sent from the same provider as your recipient’s mailbox. This technique can improve inbox placement and overall deliverability rates. While a good deliverability rate is typically 85% or higher, anything above 90% is considered excellent.
For even better results, combine Primeforge with complementary tools like Warmforge. These tools monitor deliverability and run placement tests, helping you stay ahead of potential issues. Diversifying across multiple ESPs can also reduce infrastructure strain and improve matching capabilities.
Lastly, small touches like setting up profile pictures and GIFs for each mailbox can boost visibility and engagement. In fact, using GIFs as profile pictures in Google Workspace accounts has been shown to increase reply rates by 3%–15%. These details might seem minor, but they can make a noticeable difference in maintaining a strong sender reputation.
Setting Up DNS Records: SPF, DKIM, and DMARC
Getting your DNS records right is critical for protecting your email system and ensuring your messages actually land where they’re supposed to. Properly configuring DNS records like SPF, DKIM, and DMARC helps safeguard your email infrastructure and improves deliverability.
These three protocols work together to verify that your emails are legitimate and haven’t been tampered with:
- SPF: Confirms that the server sending the email is authorized to send messages on behalf of your domain.
- DKIM: Ensures the email’s content remains unchanged during transit and verifies its authenticity.
- DMARC: Instructs receiving servers on how to handle emails that fail SPF and DKIM checks.
The stakes are high. The FBI reports that Business Email Compromise (BEC) scams have cost $50 billion globally. Despite this, only 34% of the largest 5,000 companies have implemented DMARC. Even more alarming, research from Valimail shows that 75–80% of domains with DMARC records struggle to enforce them properly.
"DMARC helps protect users from forged email messages, and lets you manage messages that don't pass SPF or DKIM." – Google Support
How to Configure and Verify DNS Records
Setting up SPF, DKIM, and DMARC involves publishing specific DNS records for your domain. While each protocol has its own setup process, understanding the basics makes the task manageable.
SPF Configuration
An SPF record is a TXT record that starts with v=spf1. It specifies which mail servers are allowed to send emails for your domain. For example, if your SPF record is v=spf1 include:example.com ~all and you want to add Mailgun, update it to:
v=spf1 include:example.com include:mailgun.org ~all. Always modify an existing SPF record rather than creating multiple records.
DKIM Setup
Generate a public/private key pair. Add a TXT record to your DNS with a selector like _domainkey.yourdomain.com. This record should include v=DKIM1, k=rsa, and your public key prefixed with p=. Regularly rotating your DKIM keys is a best practice to enhance security.
DMARC Implementation
Publish a TXT record named _dmarc. Use v=DMARC1 to define the DMARC version, and set your policy with p=none, p=quarantine, or p=reject. Start with p=none for monitoring before moving to stricter policies. Your DMARC record should also include reporting URIs (rua=mailto:email@example.com for aggregate reports and ruf=mailto:email@example.com for forensic reports). Additionally, set alignment modes for DKIM (adkim=s for strict, adkim=r for relaxed) and SPF (aspf=s for strict, aspf=r for relaxed).
Verification
To check if everything is working, send a test email to a Gmail account. Open the email, select "Show original", and confirm that SPF, DKIM, and DMARC show a "PASS" status. Tools like MXToolbox can also help you inspect your DNS records.
Checking DNS Health and Staying Compliant
Regularly testing your DNS health is essential to ensure your records are accurate and properly propagated. This supports the stability and performance of your network.
"DNS health testing is often overlooked when it comes to network performance, reliability, availability, reachability, and security."
Automated tools can simplify DNS health checks, helping you detect and resolve issues faster than manual methods. These tools often provide global DNS resolution analysis, giving you a broader view of your domain’s status.
Managing email authentication can feel daunting. As Andrew Williams, Principal Product Marketing Director, puts it:
"The challenges with DMARC is we often see that it contains an air of mystery about it because not many people understand the underpinning technologies within it."
Platforms like Primeforge take the guesswork out of DNS setup. For every mailbox you purchase, Primeforge automatically configures DMARC, SPF, DKIM, and custom domain tracking, following established best practices. This automation minimizes errors and reduces manual work.
"For each mailbox you buy with Primeforge, we take care of setting up DMARC, SPF, DKIM and custom domain tracking, following industry best practices." - Primeforge
Primeforge also offers bulk DNS management, allowing you to update authentication records across multiple domains at once.
When implementing DMARC, start with p=none to monitor your email authentication status. Review the reports, resolve any issues with legitimate email sources, and gradually move to stricter policies like p=quarantine or p=reject.
SPF works by validating the Return-Path domain, while email recipients focus on the "From" field. DMARC reporting provides valuable insights into email authentication failures, helping you maintain a secure and efficient email system.
With these practices in place, you’ll be well-prepared to monitor and manage your email authentication protocols effectively. Up next, we’ll dive into how to track these metrics to keep your email infrastructure in top shape.
Using Different Email Infrastructure Tools and Providers
Choosing the right email infrastructure is key to ensuring your emails actually land in inboxes. With nearly 45% of emails getting flagged as spam, selecting the right platform can make or break your email campaigns.
When evaluating platforms, you’ll need to consider factors like deliverability, sending limits, setup complexity, and technical requirements. A poor choice can lead to infrastructure burnout much faster than you might think.
Email Infrastructure Platform Comparison
Selecting the best email infrastructure platform depends on your needs. Gmail and Outlook are household names, but specialized tools like Primeforge cater specifically to cold outreach campaigns. Let’s break down the key differences:
Gmail (Google Workspace) is known for its simplicity and reliable deliverability, especially when warmed up properly. Starting at $6 per user per month, it allows up to 2,000 emails per day per user, though staying within a safer range of 300–500 daily sends is recommended for consistent results.
Outlook (Office 365) offers more control but requires more technical setup. At $5 per user per month, it supports up to 1,500 emails per day per user, with safe limits around 500–1,000 daily sends. Its full DNS access is a plus, but it requires expertise to configure properly.
Primeforge, on the other hand, is purpose-built for cold outreach. It automates many of the technical tasks that often cause deliverability issues. Priced at $3.50–$4.50 per mailbox per month, it supports 500–5,000+ daily sends and offers infrastructure-level control.
Here’s a quick comparison:
| Factor | Gmail (Google Workspace) | Office 365 (Outlook) | Primeforge |
|---|---|---|---|
| Daily Send Limit | 300–500 (safe ramped) | 500–1,000 (with setup) | 500–5,000+ (infra control) |
| Warm-Up | Easiest with tools | Needs configuration | Built-in warm-up system |
| Setup Complexity | Very simple | Moderate to complex | Fully automated |
| Pricing (50 inboxes) | $300/month | $250/month | $150/month |
| Best For | Light outreach | Microsoft users | High-volume campaigns |
The cost differences are striking. For 200 mailboxes, Google Workspace costs $1,680 per month, while MS365 is $1,200 per month. Primeforge, however, delivers the same capacity for just $484 per month, saving up to 70% compared to traditional providers.
Karlo Binda, Founder of Leadsnack.co, highlights these savings:
"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."
When to Choose Each Platform
- Gmail: Ideal for beginners or those running low-volume, personalized campaigns. Its ease of use and strong reputation make it a great starting point.
- Outlook: Best for teams scaling to 1,000+ daily sends, especially if you have an expert to handle DNS and infrastructure optimization.
- Primeforge: Perfect for high-volume senders who want to scale quickly without dealing with technical headaches.

Monitoring and Managing Your Email Infrastructure
Keeping your email infrastructure in top shape requires constant vigilance. Neglecting it can lead to problems like poor deliverability and a damaged reputation. According to Warmforge, 70% of emails encounter spam issues due to either sender reputation or content triggers. This makes proactive monitoring a must for maintaining success.
The secret to avoiding these pitfalls lies in tracking critical metrics and acting quickly when something seems off. Many businesses only notice issues when their emails stop reaching inboxes - by then, the harm to sender reputation can take months to fix. Regular monitoring helps you address problems before they spiral out of control.
Key Metrics and Warning Signs to Watch
To effectively manage your email infrastructure, focus on metrics that reflect the health of your sender reputation. For example, aim for a delivery rate of 95% or higher and deliverability between 88–99%. A dip in these numbers often signals that email providers are questioning your sender reputation.
Bounce rates are another important metric. Keep them under 2%. Since email lists naturally degrade by about 22.5% annually, regular list cleaning is essential to maintain healthy bounce rates.
Target open rates between 17–28% and click-through rates of 2–5%. If these numbers consistently underperform, it could mean your content isn’t connecting with your audience, which increases the risk of spam filtering.
Spam complaints are especially critical. Your spam rate should stay below 0.08%, and spam complaint rates should not exceed 0.1%. For optimal results, some experts even suggest keeping spam complaint rates under 0.01%. Addressing these complaints promptly is vital, as they can severely harm your sender reputation.
To stay ahead of potential issues, set up automated alerts to notify you when thresholds are breached. While many email service providers include built-in monitoring tools, third-party solutions often offer more detailed tracking across multiple platforms and domains. Additionally, daily blacklist monitoring is crucial. Major email providers maintain private blacklists, and landing on one can instantly disrupt your email delivery. Timely adjustments based on these metrics can help you avoid long-term damage.
Scaling Infrastructure with Primeforge
Once your metrics show stability, you can scale your email operations with confidence - and this is where Primeforge comes in. As your email volume grows, scaling without sacrificing deliverability becomes a complex challenge.

Don’t forget to regularly monitor sender reputation using tools like Google Postmaster Tools. These provide valuable insights into how major email providers view your sending practices, helping you identify and resolve potential issues before they escalate.
Conclusion: Keeping Your Email Infrastructure Healthy
Maintaining a strong email infrastructure requires a mix of proper authentication, continuous monitoring, and smart automation. It all begins with setting up the right authentication protocols. Without these safeguards, even the most well-thought-out content strategies can fall prey to spam filters and deliverability challenges. This technical groundwork is the backbone of any effective sender reputation strategy.
Sender reputation management is key to running successful cold email campaigns. It involves gradual warm-up processes, regular list cleaning, and ensuring minimal spam complaints to maintain deliverability. Did you know that one in six emails never makes it to the inbox, and 22% of marketers fail to track deliverability metrics? Those who actively monitor and optimize their email systems enjoy a clear advantage. As Carin Slater from Litmus explains:
"Deliverability is a measure of the health of your email marketing program, so it's important to do regular check-ups on your domain, IP, and authentication in particular to make sure you're up-to-date, just like how we all go to the doctor each year."
Automation also plays a crucial role in streamlining email operations. Tools like Primeforge simplify multi-domain management, cutting setup time from over 24 hours to just 30 minutes. Automated DNS configuration and bulk management features reduce manual errors that could jeopardize sender reputation. For businesses sending more than 10,000 emails daily, diversifying infrastructure across platforms like Google Workspace and MS365 ensures redundancy and reliability.
In a constantly shifting cold email landscape, regular audits and automation not only protect your sender reputation but also boost revenue by improving inbox placement. Companies that clearly define their Ideal Customer Profile (ICP) achieve response rates 3-5 times higher than those relying on generic targeting. Better inbox placement means more opportunities for engagement and growth. By combining robust technical setups, ongoing monitoring, strategic automation, and a commitment to refinement, you can build an email infrastructure that fuels long-term success while avoiding burnout.
