As we saw above, one reason is that if someone reading your email in a system with an email firewall sent you to spam, your entire domain becomes blacklisted. You can then end up with your entire domain being blacklisted, for example by
Barracuda or
Sorbs, leading you to have to spend time removing yourself.
Being blacklisted once will affect any future emails you send out.
Someone can mark you as spam for a variety of reasons.
But if you made it into the inbox then, mainly, it is related to content. They judged your content to not be valuable or important to them.
There are thus two things to look at:
Firstly, the body and content of your message. And secondly, how well the prospects you contacted match the ideal customer profile for your product or service as a salesperson.
Additionally, email firewalls also perform more technical verifications related to email authentication. These include checking for methods that ensure you as a sender are protected, and thus anyone who receives an email from you is also protected.
If you do not have at least one method implemented, you will likely end up in spam.
With these checks,
ISPs will also often look into engagement rates.
High engagement rates signify that it is a real email address and not a spammer sending out mass emails to try to catch people unaware. Thus, another reason to ensure your content and prospect list are in tip-top shape is to increase engagement rates.
As you can imagine, avoiding spam is about responding to the above issues before they happen. Let’s take a closer look.
