Will your email land in spam?

Send one email to our seed inboxes at Gmail, Outlook, Yahoo and business mailboxes. In a few minutes you see where each copy landed, a score out of 10, your SPF, DKIM and DMARC results, and what in the content filters dislike.

  • Real mailboxes, real placement: inbox, spam or missing
  • Personal and business inboxes, or a mix
  • Authentication as the receiving server saw it
  • Content checks: spam words, links, images, size
  • 3 free tests a day, no account

Free tests open at launch

The Send Labs is in private beta, so free public spam tests are paused. Beta customers run spam tests inside the app.
