Gmail Spam Filter Builder

Tip: in a junk email, the sender address is in the "From" line. You can also paste a whole domain like mailchimpapp.net to catch everything from it.

(paste some addresses above)

1. Gmail → ⚙ Settings → See all settings.
2. Filters and Blocked Addresses tab → scroll down → Import filters.
3. Choose the downloaded .xml file → Open file → Create filters.
4. Tick "Apply to existing conversations" to sweep what's already in there. Done.

To add more senders later: run this tool again with your full list and re-import, or just open the existing filter (Edit) and append OR newsender@x.com to the "from" box.

Report Spam first, filter second. For a week, hit Report Spam (not just Delete) on the junk. That trains Google's own filter on the pattern and catches the rotating sender addresses these outfits use. Then add this filter as a backstop for whatever slips through.

Filter on words, not just senders, when they keep changing addresses. Put this in a filter's "Has the words" box to catch an entire genre of marketing spam:

"OTO" OR "one-time offer" OR "DFY" OR "WarriorPlus" OR "JVZoo" OR "bonus bundle" OR "limited memberships" OR "grab it all here"

Catching real mail by accident? Remove the broadest terms first. Prefer senders? Use from:(warriorplus.com OR jvzoo.com) to kill the payment-processor notifications these funnels ride on.

• Delete vs. archive: "Delete it" sends to Trash (gone in 30 days). "Skip inbox + archive" keeps a searchable copy in All Mail — safer if you're nervous about false positives.
• Filters can't Report Spam — that's why you train Google manually first.
• One master filter with a long OR list beats 40 separate filters. Easier to edit, same result.
