What should I do before requesting removal from any blocklist?

The most critical mistake senders make is rushing to request delisting without fixing the underlying problem. Blocklists exist because something went wrong - submitting a removal request without addressing the root cause wastes everyone's time and often results in immediate re-listing.

Universal pre-delisting checklist:

1. Identify the root cause

  • Check when the listing occurred - what changed around that time?
  • Review your sending logs for anomalies (spikes, new campaigns, new sources)
  • Check for compromised accounts or scripts
  • Review recent list additions for purchased or scraped data

2. Stop the bleeding

  • Pause all sending from the listed IP/domain if needed
  • Disable any compromised accounts or vulnerable forms
  • Remove problematic content or links

3. Fix authentication

  • Verify **SPF** includes all legitimate sending sources
  • Confirm **DKIM** is signing properly
  • Check **DMARC alignment**
  • Fix rDNS (PTR records) for sending IPs

4. Clean your lists

  • Remove bounced addresses
  • Suppress unsubscribes globally
  • Consider running verification on older addresses
  • Remove addresses with no engagement

5. Check for ongoing issues

  • Monitor complaint rates
  • Verify unsubscribe process works
  • Ensure all senders on your IP are legitimate

6. Document what you've done

  • Blocklists often ask what caused the listing and what you've fixed
  • Having clear answers speeds up removal

Then, and only then, submit your removal request.

Requesting delisting without fixing the problem is like asking the coast guard to remove a hazard warning while your ship is still on fire. They're not trying to be difficult - they're trying to prevent you from sinking and taking others with you.
