Pre-flight check before a Black Friday send

During BFCM, inbox providers tighten their reputation thresholds. A 3% bounce rate that Gmail would shrug off in August will trip their deferral logic in November. Validate 24–48 hours before the send so you can exclude undeliverables from the campaign audience.

1. 1

   Pick the exact audience for the send

   Whichever list or segment you plan to send to — Securify supports both. If you're sending to "all engaged subscribers in the US," validate the segment that matches.
2. 2

   Run Securify 24–48h before the scheduled send

   Longer-ignored addresses often decay — a profile that was deliverable 3 months ago may be closed now. A fresh run right before the campaign catches that drift. Use Check and tag: the exclusion in the next step reads the tags.
3. 3

   Suppress undeliverables in the campaign audience

   When creating the campaign, use the segment above AND exclude anyone where securify_status is one of undeliverable, risky, disposable. One-click narrowing — you don't have to rebuild the segment.
4. 4

   Keep the unverifiable and catch-all profiles for post-BFCM

   Unverifiable addresses (providers that refuse checks) and catch-all ones (domains that accept any address) are mostly real customers, but you can't confirm them before the send, and inbox providers judge every bounce harder in peak season. Send to profiles where securify_status is one of unverifiable, catch_all a week later, when the pressure is off.
