The confirmation email is usually the first email your contacts receive.<\/strong><\/p>\n\n

What is more, it is the email with which they finalize the subscription process; normally, if they don’t click on the link included in this email, their subscription remains incomplete and you will not be able to send them more emails.<\/p>\n\n

This is precisely why the confirmation email is so important.<\/p>\n\n

And you must take maximum care of it.<\/p>\n\n

It is not just another email.<\/p>\n\n

In this article, we are going to look at the most important aspects you should take care of, and how to do it with Mailrelay.<\/p>\n\n\n\n

It can’t be just because it is a confirmation email, or all spammers <\/a> would create their emails to look like confirmation emails.<\/p>\n\n

In that case, destination servers usually use, among others, three parameters:<\/p>\n\n
