Of course, everyone wants to avoid getting blacklisted. Here are some things you can do to keep your email account from blacklists:

1. Never enter email addresses manually into your database

Sure, you feel extremely productive and want to enter email addresses manually. No one’s stopping you.

However, you may want to take note that this type of practice can result in numerous typos — and you don’t want that.

You would want to avoid sending messages to non-existent emails resulting in email bounce and being added to an email blacklist.

Moreover, you should also avoid adding email addresses you’ve obtained physically like business cards, especially if the person didn’t give you permission.

Once you send them a sales email, they would most likely report it as spam.

2. Optimize your email content

Personalize your emails as much as possible and avoid sending generic ones. By doing so, you can reduce spam complaints.

You can use email marketing softwares in crafting highly customized emails.

If you offer your recipients valuable content, they wouldn’t flag your email as spam.

3. Include an unsubscribe link

Follow anti-spam laws at all times. One thing you can do is to add an unsubscribe link to your email.

Aside from doing so means you’re adhering to the rules, you’re also improving your target audience’s experience.

4. Secure your server

Yes, you have to put proper security measures in place. It’d also be best if you use certain IP checking tools to protect the server from malware or bots. You don’t want to be the victim of an email hijacking.

Failure to do so can get you blacklisted no matter how you strictly followed the best email marketing practices.

You can use an IP email blacklist lookup tool to determine if anyone else is using your IP address. If the results say it is being used by another server, it means your network server was hacked.

5. Clean your email lists regularly

Proper list management is important to keep your email out of blacklists. You’d want to have early detection of spam traps before you fall right into them.

You can start by updating your email list. Subscribers who haven’t engaged with you for at least six months should get re-engagement emails. And if they remain unresponsive, you can add them to your list of potential spam traps.

Also, you have to check for email address typos to avoid spam traps and invalid contacts contaminating your list.

Always use email validation tools to check the legitimacy of the email addresses.

6. Use double opt-in

This is a sort of two-step verification. After signing up to your mailing list, the user will receive an email where they can confirm their subscription.

This practice can make sure that all of your subscribers are real people.

It also verifies if the user really wants to receive your emails — new offerings, promotional offers, or newsletter.

With the double opt-in method, you can reduce complaints about email spamming and also lower unsubscription rates.
