How to handle suspected trap hits?

First: don't panic, but don't ignore it either. Suspected trap hits are recoverable if you act systematically. Here's what to do.

Step 1: Pause sends to the affected segment

If you have any indication that trap hits are coming from a specific segment, stop sending to it immediately. Not forever. Just until you've worked out what's in it. Every send to a trap-laden segment makes the situation worse.

Step 2: Identify the acquisition source

Where did those addresses come from? Which import, which campaign, which signup form? Most trap hits trace back to a specific source: a purchased list, an old database import, a co-registration program. Find the origin and you've found the risk. Addresses that came in through organic double opt-in are almost never the problem.

Step 3: Run validation on the suspect segment

Put the segment through email validation. Look for addresses flagged as risky, unknown, or associated with parked domains. You're not going to get a list of confirmed trap addresses. You're going to get a risk picture that tells you which addresses to suppress.

Step 4: Suppress, don't just unsubscribe

Risky addresses from that segment should go to your suppression list, not just your unsubscribe list. If your ESP has the concept of a global suppression, use it. You want to make sure these addresses never get mailed again, regardless of which list or segment they might appear in.

Step 5: Warm back up gradually

If you've paused a significant portion of your list, don't just flip it back on. Resume with your most engaged subscribers first and warm back up gradually. This signals to inbox providers that you're sending to real people who want your mail.

If you're actively listed on a blocklist and need to get off it, the path is: fix the root cause, then submit a delisting request through the blocklist's process. Review My Emails' SOS hotline (reviewmyemails.com/sos) can walk you through a delisting if you're stuck.
