Using the Subswell fields in your email platform

Segment readers by partner, or leave out rejected ones.

Updated October 3, 2026 · 1 min read

Every reader we deliver to your list gets two fields in your email platform:

  • Subswell status: pending while in the quality check, then confirmed or rejected.
  • Subswell partner: the newsletter that recommended you.

We create them the first time they're needed. Use them to send a welcome sequence per partner, or to leave rejected readers out of your sends.
