Due to some programming integration tests I've setup to run often, I'm receiving emails to my gmail with a plus address like so:

  • matt+unittest_1
  • matt+unittest_2
  • matt+unittest_3


I would like to filter out email I receive to the +unittest_* addresses; however I can't seem to find the right search term. When I search for one specific plus address it finds the email; however searching the 'to' address for 'unittest' or any combination thereof does not work.

Is this possible using Gmail (well technically G Suite since it's a custom domain... but Gmail).

  • Unfortunately, no. Unless you can craft a search which works for you, you can't create a filter for it. Gmail search doesn't really do wildcards mixed with other texts. I would have suggested to try to:unittest_, but you've indicated that that doesn't work.

Yes, Gmail allows use of the wildcard (*) before and after. Use *unitest*. As mentioned, verify the filter works as expected with a search, then save as a filter. I first did this unintentionally - it works!

    To date, wildcard searching in Gmail is generally not supported. I feel that you've hit on something which you think is giving you the results you want, but it's only a coincidence based on the data you have. It would better if you could back this up with some documentation from Google Support.
