What it does

Soft bounces that keep repeating quietly drag down your reputation because you keep hammering mailboxes that will never accept your mail. This workflow promotes chronic soft-bouncers to your suppression list automatically, so a transient deferral that became permanent stops costing you sends.

When to use it

Use it when your send logs distinguish soft from hard bounces and you maintain a suppression table in Postgres. It is the hygiene routine that keeps your active list clean without anyone manually combing bounce logs.

How it works

  1. 1A twice-daily schedule starts the run.
  2. 2A Postgres query finds addresses with three or more soft bounces in the trailing 14 days that are not already suppressed.
  3. 3A logic step de-duplicates and caps the batch so a bad day cannot suppress your whole list at once.
  4. 4A Postgres insert adds the qualifying addresses to the suppression list.
  5. 5A Slack message to the list-hygiene owner reports how many were added and attaches the CSV of suppressed contacts for review.

  4. 4
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  5. 5
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
