Recovering from Multiple Email Delivery Issues

What's happening

Your bounces show several different problems at the same time, for example rate limits, low domain reputation, spam-like content and DMARC failures. Each issue makes the others worse, so fix them in order.

Fix in this order

  1. Infrastructure first
  2. Authenticate your sending domain with SPF, DKIM and DMARC.
  3. Make sure the From domain aligns with your authenticated domain.
  4. Reputation next
  5. Pause bulk sends to unengaged contacts.
  6. Remove hard bounces, complainers and contacts with no engagement in 90+ days.
  7. Check whether your domain or links are on a blocklist and request removal.
  8. Content
  9. Simplify templates, reduce links, remove shorteners and avoid spam-trigger wording.
  10. Volume
  11. Restart with your most engaged contacts and raise volume gradually over 2–4 weeks.

What to expect

  • Authentication fixes take effect within hours to two days.
  • Reputation recovery usually takes 2–6 weeks of consistent, clean sending.

Watch during recovery

  • Bounce rate below 2%
  • Spam complaint rate below 0.1%
  • Open rate trending upward
If any metric gets worse, slow down and send only to your most engaged segment.
