Deliverability tools have traditionally treated all mailbox providers as equals.
Questions like “Where is my mail actually going?” and “Which ISPs should I care about?” have evaded marketers for years. Weighing priorities based on seed test results have largely been best-guess efforts.
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.
How it works:
Upload a segment of your mailing list
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?
250ok analyzes where your mail is going
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.
Apply the results for optimized seed testing
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.
