OutcomeA contact who did not open the first send of a specific email automatically gets the same content again, 3 days later, under a different subject line, without a marketer manually pulling and re-sending a non-opener list.

When to use it, when not to

Use it

  • Use for a single, specific email send where the content matters enough to justify a second attempt, for example a key nurture step or an important announcement.
  • Use it once per email. This fiche is a single resend, not a repeating retry loop.

Skip it

  • Do not use it for every email in a sequence. Resending every single step doubles send volume and can read as spammy if applied indiscriminately.
  • Do not use it on a legally required or time-sensitive notice where a second identical-content send under a different subject could cause confusion about which one is authoritative.
