If you will be sending your email blast through an email service provider (ESP), Seed List Spam Testing is our recommended option. To do this, cut and paste the email addresses from the Seed List provided and send a test email via your ESP. This extra step is really worth it, and will provide you with the most accurate test results!

This will allow us to test each of the following:

  • Email Server Reputation
  • Sender Email Address
  • Sender IP address
  • Email Server Configuration
  • Email Content and Subject Line
  • IP Blacklisting


The Seed List will also be available in your test results, just click "view Seed List." If any test results are missing after an extended period of time, or if you mistakenly send your email before initiating the Seed List Spam Test in your account, re-send the email (with the same subject and content) to the Seed List addresses to encourage any missing results to populate. You must send the exact same email with the exact same subject and content in order to associate with your existing test correctly. 

Please be sure to send your email directly to the Seed List addresses, without the use CC/BCC/FWD. Once you've pasted your uniquely generated Seed List into the recipients field and entered content into both the subject and body, you're ready to send your email for Seed List testing! It is important to include content in both the body and subject of your email, as blank emails/subjects may cause the test to malfunction. 

Seed Lists are uniquely generated per Spam Test, and you cannot use the same grouped Seed List on multiple Spam Tests. Using the same group of emails on different tests will disrupt the successful testing process.
