What is the seedlist optimizer and why should I use it?

Historically, most deliverability tools have treated receiving ISPs as equals, but that’s clearly not the case. Before the seedlist optimizer, weighing your priorities were typically a best-guess effort. By uploading a sample of your mailing list to the seedlist optimizer, we’ll analyze where your mail is actually going to provide total visibility into which ISPs make up your mailing list so you can prioritize resource accordingly.

It’s also worth noting:

  1. 250ok does not store your mailing lists. They are discarded after the analysis is complete.
  2. The seedlist optimizer simply needs the qualified domain, so you’re free to redact the ‘@’ symbol and anything to the left of it while still ensuring accuracy.
