Best Time to Send Cold Emails in 2025

In 2025, timing is everything when it comes to cold email success. Sending emails at the right time can significantly boost open rates, click-throughs, and replies. Here's what you need to know:

• Best Day: Monday leads with open rates over 20%, while Thursday performs poorly with the highest unsubscribe rates.
• Industry Timing Insights:
  • Software/SaaS: Tuesday–Thursday, 9:00–11:00 AM.
  • Real Estate: Wednesday–Thursday, 10:00–12:00 PM.
  • Marketing: Monday–Tuesday, 9:00–10:00 AM.
• Email Infrastructure Matters: Tools like Primeforge ensure emails reach inboxes by automating SPF, DKIM, and DMARC setups, using U.S.-based IPs, and offering features like ESP matching.

Without proper infrastructure, even well-timed emails can fail. Primeforge offers a cost-effective solution ($3.50–$4.50/month per mailbox) compared to Google Workspace ($6.00/month) and Microsoft 365 ($8.40/month). It simplifies setup, improves deliverability, and supports large-scale campaigns.

Key Takeaway: Combine precise timing with reliable infrastructure to maximize cold email performance in 2025.

1. Primeforge

Primeforge is a dedicated email infrastructure provider tailored for cold outreach campaigns. Unlike generic email services, it focuses on optimizing technical aspects to ensure your messages land in inboxes at just the right time.

Here’s a closer look at Primeforge’s standout features that enhance both deliverability and campaign efficiency.

Deliverability Features

One of Primeforge’s key strengths is its ESP Matching feature, which ensures emails are sent from the same mailbox providers as your prospects. This is particularly effective for boosting deliverability when targeting Google Workspace and Microsoft 365 accounts.

The platform also automates DNS setup, handling critical authentication protocols like SPF, DKIM, and DMARC. These protocols are essential for passing email provider checks and ensuring your messages avoid spam folders.

"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! Excited to spin up some Outlook accounts soon also." – Rahul Lakhaney, Former VP, Gartner, now CEO @ Enrich.so and Maximise

Another advantage is Primeforge’s use of U.S.-based IP addresses, which helps maintain high inbox placement. This is particularly useful when sending large volumes of emails during busy hours, as it minimizes the risk of messages being flagged by spam filters.

Time Zone and IP Location Advantages

All Primeforge domains and mailboxes come with U.S.-based IP addresses. This is a significant benefit for businesses targeting American audiences, as it ensures emails sent during peak U.S. hours are less likely to appear suspicious. This localized approach helps maintain a strong sender reputation and supports multi-campaign strategies with ease.

Scalability for Complex Campaigns

Primeforge is built to handle the demands of multiple campaigns. Its multiple workspaces feature allows users to organize domains and inboxes by client, campaign, or team. This is particularly helpful when managing campaigns across various industries or time zones, each with unique sending schedules.

Additionally, the platform’s bulk DNS management simplifies scaling by enabling users to update authentication records across numerous domains at once. This efficiency is a game-changer for teams managing high-volume outreach.

Quick and Simple DNS Setup

Primeforge significantly reduces setup time. While traditional setups can take over 24 hours, Primeforge cuts this down to just 30 minutes. This rapid setup allows businesses to quickly adjust their strategies and get campaigns running without delays.

At $3.50–$4.50 per mailbox per month, Primeforge offers a cost-effective solution. When factoring in its quick setup and optimization features, businesses can save up to 46% compared to purchasing mailboxes directly from Google or Microsoft. This pricing structure frees up resources, allowing companies to focus on refining their outreach strategies instead of dealing with technical hurdles.

2. Standard Email Infrastructure Providers

While Primeforge provides automated, tailored solutions for cold outreach, standard email infrastructure providers like Google Workspace and Microsoft 365 come with notable limitations. These platforms, originally designed for general communication, aren’t built to handle the demands of high-volume email campaigns. While they can technically support cold emails, their lack of automation and scalability can hinder both timing and success of campaigns.

Deliverability Features

Standard providers typically offer basic email authentication through SPF, DKIM, and DMARC records, but the setup process is manual and can be technically challenging. According to a 2025 report, over 45% of cold emails fail due to technical issues rather than poor messaging. Additionally, Validity's 2024 Email Benchmark revealed that 21% of B2B emails never make it to inboxes because of improper domain or IP configuration.

Another drawback is the use of shared IP addresses. This means your sender reputation can be negatively impacted by others using the same server. Unlike specialized platforms, these providers lack advanced tools like automated email warmup, custom tracking domains, and blacklist monitoring, which are essential for improving deliverability rates.

Time Zone/IP Location Flexibility

Standard services like Google Workspace and Microsoft 365 offer basic email scheduling, but they fall short when it comes to optimizing send times for different regions. This can be a serious issue, as 23% of all emails are opened within the first hour of delivery, with open rates dropping by half in the second hour. Furthermore, these platforms rely on automated geolocation to determine sender IP location, leaving users with little control over where their emails appear to originate. Without IP rotation capabilities, it becomes difficult to manage sender reputation or target specific regions effectively, which limits scalability and performance.

Scalability for Multiple Campaigns

Managing multiple campaigns with standard providers often becomes a logistical challenge. Daily sending limits can restrict outreach efforts, especially when working with large prospect lists across various time zones. These constraints can cause delays in campaign launches and make it harder to adjust strategies in real time, ultimately reducing the likelihood of reaching prospects during their peak engagement periods.

Ease of DNS Setup

Setting up DNS records with standard providers is another obstacle. The manual configuration process can take anywhere from 24 to 48 hours, with each domain requiring separate setup. This delay can be a major setback for time-sensitive campaigns, especially when quick adjustments are needed to respond to shifting market conditions.

Comparison of Email Infrastructure Solutions

Selecting the right email infrastructure for cold outreach in 2025 highlights the clear distinctions between specialized platforms and standard providers. Timing your emails perfectly is critical, but without the proper infrastructure, even the best-timed messages can fail to reach their audience.

The table highlights how Primeforge's specialized features cater specifically to cold outreach, offering advantages in deliverability, setup efficiency, and cost. With automated SPF, DKIM, and DMARC setup, along with dedicated US-based IPs, Primeforge ensures better inbox placement and minimizes the risks associated with shared IP addresses. Its bulk DNS management and cold email optimization tools also streamline operations, making it a standout choice for businesses looking to scale their outreach efforts.

One of the key differentiators is Primeforge’s US-based IP infrastructure, which is particularly effective for targeting American audiences. Platforms like Smartlead have demonstrated the value of timezone optimization, reporting a 20% boost in email engagement rates by aligning email sends with recipients' peak activity windows. Considering that over 70% of people check emails on mobile devices, often during set daily routines, timing becomes even more critical.

Reputation management plays a pivotal role in email performance. Standard providers rely on shared IP addresses, which can negatively impact your sender reputation due to the actions of other users. Primeforge mitigates this risk with dedicated IPs, helping maintain strong inbox placement rates. Industry benchmarks suggest that an inbox placement rate of 85% is considered strong, with rates above 90% being exceptional.

For businesses aiming to maximize the impact of their cold emails, investing in the right infrastructure can mean the difference between hitting key engagement windows and being overlooked entirely.

Achieving cold email success in 2025 hinges on more than just timing - it requires a strong email infrastructure. While sending emails at the right moment is important, ensuring they actually reach your recipient’s inbox is what truly makes the difference.

This is where selecting the right provider becomes critical. Primeforge stands out as a top choice for businesses focused on cold outreach. With pricing between $3.50 and $4.50 per mailbox per month, it’s a more cost-effective option compared to Google or Microsoft, which charge $6.00/month and $8.40/month, respectively. Beyond affordability, Primeforge offers features that standard providers don’t, like automated setup for SPF, DKIM, and DMARC.

For businesses targeting the U.S., Primeforge’s US-based IP infrastructure is a game-changer.

Experts, including Rahul Lakhaney, highlight these advantages, emphasizing how they can enhance your outreach efforts.

To further strengthen your email strategy, consider combining Primeforge with other providers like Mailforge (priced at $2–$3 per mailbox) or Infraforge (starting at $49/month).

Timing is a key factor when it comes to the success of cold emails, and the ideal time can differ depending on the industry. For those in Software, the sweet spot tends to be between 9:00 AM and 11:00 AM or early mornings from 6:00 AM to 9:00 AM on Tuesdays through Thursdays. In Real Estate, mid-morning to early afternoon - specifically 10:00 AM to 2:00 PM on Tuesdays and Thursdays - is more effective, while early mornings and late evenings are best avoided.

Why are U.S.-based IP addresses important for cold email deliverability when reaching American audiences?

Using IP addresses based in the U.S. can make a big difference in how well your cold emails perform when reaching out to American audiences. These IPs build a stronger sender reputation, lower the chances of your emails being marked as spam, and reduce the likelihood of ending up on blacklists.

If your business is targeting U.S. prospects, matching your IP location to your audience's region helps email providers see your messages as more reliable. This can lead to higher open and reply rates, boosting the overall success of your cold email campaigns.
