3. 3. Turn on double opt-in and check for listbombing

   Copy steps
   1. Use confirm-opt-in on forms so fake signups never become subscribers
   2. Review recent signups for bursts of random addresses and follow Kit's listbomb article

4. 4. Prune cold subscribers

   Copy steps
   1. Segment subscribers who have not opened or clicked for months
   2. Remove or re-engage them before the next send; confirm everyone gave direct consent
   Did this fix it? Yes No

5. 5. Test with an outside address

   Copy steps
   1. Send test emails to a Gmail or other outside address, not your own domain
   2. For internal mail, ask your domain admin to allowlist Kit's IPs
   Did this fix it? Yes No

Symptoms

Broadcasts, sequence emails or confirmation emails land in spam or Promotions, or open rates suddenly drop.

Why it happens

• Sending from a public domain such as gmail.com or yahoo.com
• Sending domain has a DMARC policy but is not verified in Kit
• Signup forms listbombed with fake addresses
• Cold or non-consenting subscribers on the list
• Messages sent to the same domain they come from (looks like spoofing)
