Email Deliverability Fixes

If your open rates drop below 20% or your bounce rate exceeds 3%, you have a deliverability problem. Here is how to diagnose and fix it.

Diagnosing the Problem

Go to Reporting → Email Health and check:

Fix: High Bounce Rate

  1. Pause the affected campaign immediately
  2. Export the bounce list from Reporting → Bounces
  3. Remove all hard-bounced emails from future campaigns (the platform auto-suppresses, but verify)
  4. If bounce rate came from a purchased list, never use that list source again

Fix: High Spam Rate

  1. Review your most recent sequence for spam trigger words
  2. Remove all images and HTML styling — send plain text only
  3. Reduce daily send volume by 50% for 7 days
  4. Run a seed test to measure current inbox placement
  5. If spam rate remains above 0.3%, rotate to a new sending domain

Fix: Low Open Rate (Deliverability Cause)

Low open rates can be caused by deliverability OR subject lines. To isolate:

  1. Send a test email to your own inbox — does it arrive in inbox or spam?
  2. Run a seed test (Settings → Email Domains → Seed Test)
  3. If placement is fine but opens are low, the issue is the subject line — not deliverability
