That's why we've innovated seedlist testing with the Seedlist Optimizer. An industry first, the optimizer analyzes and identifies the composition of your mailing list to personalize your seed testing around your outbound mail stream.
By uploading a segment of your mailing list, you can now receive a personalized, weighted seedlist for more accurate deliverability testing. You may find that the majority of your list goes to the "Big 4" global ISPs such as Gmail, Apple, AOL, and Hotmail. In fact, many of our customers are sending about 25% of their mail to Gmail. But what about the other 100+ ISPs we cover?
As the optimizer churns through your mailing list, we'll tell you where your mail is actually going and give you more visibility into which ISPs you should focus on. Similarly, you'll also get a better idea of which blacklists to monitor more closely and which mail clients you should optimize your campaigns around.
Once you apply this weighting to your seedlist, you'll start seeing the "weighted" results at the bottom of your 250ok Inbox tests, providing a more accurate view into the health of your inbox placement. You can then allocate your resources based on the ISPs that matter most to you.

Authentication is made up of all of these topics and a little more. It’s a nice building block in the tower of responsible email marketing. In the early, Wild-West days of email marketing in the early […]
