Best Practices to Optimize Your Cold Email Infrastructure

Now that we’ve covered the best tools you can consider using according to your individual requirements let’s also quickly discuss the 5 best practices to ensure your cold email infrastructure is optimized for optimal deliverability.

Buy Top-Level Domains

Top-Level Domains (TLDs) are the last part of a domain name, like .com, .net, or .org. These are crucial because they help establish the credibility of your email address.

In fact, having multiple TLDs can help you improve email deliverability in multiple ways. For starters, it can enhance your emails’ credibility, making them look more professional and trustworthy.

Secondly, when you have multiple domains, you can easily switch between one another in case one domain gets flagged or blacklisted.

The best practice is to diversify your sending domains across different TLDs to spread out the risk of getting blacklisted and monitor the performance of each TLD to focus more on those with higher delivery rates.

Redirect Domains

Once you’ve bought the secondary domains to send your outreach emails, the next important step is to redirect all of them to your primary domain.

For example, if your primary domain is:

www.example.com

and your secondary domains are:

www.getexample.com
www.examplepro.com

Both of your secondary domains should automatically redirect all visitors to your primary domain, which is www.example.com.

This helps to ensure a cohesive brand presence and prevents any potential confusion among your prospects.

Set Up DMARC Properly

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that helps protect your domain from being used in email spoofing and phishing.

When setting up DMARC records for your secondary domains for outreach, ensure you’re setting your policy to “quarantine.” This basically instructs email service providers like Gmail, Yahoo, etc., to treat messages that fail DMARC checks as suspicious and move them to the spam or junk folder.

Proper DMARC setup is crucial for improving deliverability because it protects your domains from being spoofed, filters out potential threats, and ensures your emails reliably reach the primary inboxes.

Custom Tracking Domain

Having custom tracking domains is equally important to improve and maintain high email deliverability across all your secondary domains.

A custom tracking domain allows you to track emails and website visits that come from your cold outreach emails. This custom domain looks more professional and trustworthy to your prospects.

Plus, using a custom tracking domain helps improve email deliverability because it separates your email traffic from your main website domain. Furthermore, email service providers are less likely to flag or block emails from a dedicated tracking domain than a domain that also handles other business operations.

As a result, it keeps your main domain’s reputation clean while giving you more control and ownership over your email data and analytics.

Warm-Up Email Accounts

Email warming is the process of gradually increasing the volume of emails sent from a new or inactive email account. This is an extremely crucial step to build a positive sending reputation with email providers.

In other words, warming up your email accounts helps avoid spam filters by preventing your emails from being flagged as spam, builds trust by establishing a good sending reputation, and identifies issues early by detecting and resolving potential problems before sending large volumes of emails.

While cold email infrastructure tools provide email warmup service for free, you should still ensure that your email accounts are regularly warmed up to avoid consistently landing in the spam folder.


Conclusion

So there you go! As you’ve learned, the right cold email infrastructure tools can drastically increase your email deliverability and, thus, your open rates. This will lead to more engagement and, eventually, more conversions.

Just remember to monitor your email deliverability, stay up-to-date with the latest best practices for your emails, and adjust your strategy as needed.

FAQs

1) What does email deliverability mean?

Email deliverability is basically the ability of your emails to successfully reach your prospect’s primary inbox and avoid their spam folder. If your email deliverability is high, more of your emails will hit the primary inboxes, giving you a better chance of opening and reading.

2) How to fix email deliverability?

Fixing email deliverability issues involves a few key steps:

  • Clean Your Email List: Make sure you’re only sending emails to people who want to receive them. Remove any invalid or inactive addresses.
  • Authenticate Your Emails: Use tools like SPF, DKIM, and DMARC to verify your email’s authenticity. This tells email providers that your messages are legit.
  • Avoid Spammy Content: Keep your email content clean and professional. Avoid using too many links, all caps, or excessive punctuation.
  • Monitor Your Sender Reputation: Monitor your sender score. If it drops, email providers mark your messages as spam.

3) How to increase the email deliverability rate?

There are several strategies you can deploy to increase your email deliverability rate. The most recommended methods include using a professional ESP, regularly validating your prospect list, authenticating, and warming up email domains designed for outreach to attain maximum deliverability.
