Email spam protection is one of the biggest challenges online newsletter experts faces with any newsletter service.

This mean before actual sending of my email blast, email spam tool should tell me probability of email going to spam.

How to Get Rid of Spam Emails

  • Your domain should be DKIM signed. This is must to get rid of spam emails. This means every email sent should be DKIM signed.
  • Make sure your email has unsubscribe link. This is single most reason for your emails going to spam. Validate for unsubscribe link with every email blast.
  • alt attribute value should be present in img tags.
  • title attribute value should be present in anchor links.
  • Make sure you are not sending only image emails with your online newsletter service. Probability of these kind of emails going to spam is very high.
  • Maintain an equivalent HTML to text ratio content.
  • While sending HTML email make sure you are also sending text version of the email.
  • Make sure your text version is similar to HTML version. Don’t modify text version too much. It’s a good practice to generate text emails from your HTML version by stripping all HTML tags.
  •  Don’t send emails to those users who have marked your email as spam. Most mass mailer services will provide you delivery report of users who have marked emails as spam.

Bulk Usage with your Email Blast

Mail Tester also provides JSON api which you can integrate with your online newsletter service in production mode for bulk usage. They have reasonable pricing model. We have written robust ruby library for the integration. In case you need please contact us.

Conclusion

It’s one of the top tool for email spam protection to be used with online newsletter service. Many ESP(email service provider) companies have built their online newsletter services on top of this. Mail Tester doesn’t guarantee that after using their tool your emails will not go to spam. However after using the tool with our in-house email blast service for 6+ months I can say that it has improved our deliverability by 50%.

I have been a big Amazon Web Services fan especially Amazon SES. You can  get started with programming amazon web services from below.
