Free mailbox providers, anti-spam vendors, ISPs, and email service providers (ESPs) all use blacklists to keep their systems free of spam. In order to prevent your emails from reaching the inboxes of your intended audience, blacklist operators will add your email address to their list and block your content. Blacklisting can be caused by bad email content, poor email list management and spam complaints

How to Avoid Email Blacklists

• Use double opt-in for your email subscribers
• Include an unsubscribe link
• Your email list should be maintained
• Optimize the content of your email
• Secure your server
• You should not manually enter email addresses into your database

1. Use double opt-in for your email subscribers

In order to ensure that your email subscribers are authentic, you should implement a two-step verification process. This serves as an additional layer of protection against spam and ensures that your subscribers are real people, not robots. As a result of the additional signup process, you can rest assured that your email recipients want to receive your newsletter, promotional offers, or product announcements. It also reduces the possibility of people unsubscribing from your mailing list due to complaints about your company’s email spamming.

2. Include an unsubscribe link

Keep your domain’s anti-spam rules in check by include an unsubscribe link in all of your email correspondence. This will help you stay in line with the rules and regulations while also improving the user experience for your subscribers. Make it easy for recipients to opt out of receiving future emails by including an unsubscribe link in each one.

3. Your email list should be maintained

Effective list maintenance and thorough evaluation of your email lists for spam traps are essential to avoiding a blacklist. Make sure you’ve got the most current email list. Customers who have been inactive for six months or more should be contacted via re-engagement emails. In order to avoid falling into a spam trap, delete any contacts who do not respond.

Keep the list free of contaminates by verifying that the email addresses of your subscribers are spelled correctly to avoid the contamination of your list with invalid email addresses and spam traps.

4. Optimize the content of your email

Prevent sending email blasts with generic messages in order to minimize spam complaints. You will also avoid email blacklist and URL blacklists. In order to send out highly tailored emails, use email marketing software like Zoho Campaigns. Modify the look and feel of your emails by dragging and dropping elements like text, buttons, photographs, HTML snippets and polls into the email editor provided by the software.

5. Secure your server

Implement the appropriate security steps and make use of IP address checking tools to keep your email server safe from bots or viruses that could steal your IP address and email domain.

Even if you follow to standard email marketing practices, these malicious software can send you fake emails, resulting in a blacklisting. Check your IP address with an IP lookup tool to determine whether someone else is using it.

6. You should not manually enter email addresses into your database

To avoid email address typos, don’t manually enter your contacts into your database. You should avoid adding people who haven’t committed to receive emails from you. They may report your email as a spam. And you may end yourself on a spam blacklist. Use an opt-in form or landing page instead of sending emails directly to prospects’ personal inboxes.
