Cold email is a good option for an in-depth presentation of products, services, and materials that comply with the client. However, there’s a “but, and also, it’s not just about sending made-like-a-clone emails. You must vary the domain you use in your cold email campaigns to get the results while staying within your targets.

What is a Cold Email Domain?

A cold email domain is a domain name specifically used for sending cold emails. Cold emails are sent to potential customers or clients who have not previously engaged with your business.

Use the best email domain name that closely matches your main website address; this makes it easier for customers and prospects to recognize and trust your emails. When you send a message about a deal from a real seller, the slight difference in the domain name is usually negligible to the recipient.

However, spammers exploit this tactic by using domain variations that look almost identical to legitimate ones. This method, known as spoofing, helps them bypass spam filters and makes their emails appear more credible. As a result, recipients are more likely to see and click on these fraudulent emails, thinking they are legitimate.

By applying different email accounts and subdomains, the email materials are from various sources rather than simply from a single individual or organization, which makes spam detection much more complicated. That could help people who want to read the emails more and are less likely to be marked as junk mail.
