I know you can filter emails in Gmail by utilizing plus signs (e.g., bob+something@gmail.com). But is there a way to filter for the opposite - that is, include emails in gmail only where a plus sign is included (and regardless of what it is)? E.g., only show bob+xx@gmail.com or bob+zz@gmail.com, but not bob@gmail.com?

  • I assume you're referring to gmail's filter mechanism?

  • If you mean you want to filter f.e. the e-mail address foo+bar@gmail.com then the answer is that e-mail addresses cannot contain + signs. If you didn't meant this, your question is formulated quite weirdly... Jun 21 '12 at 20:31

    @stevenroose: You certainly can use plus signs in email addresses. webapps.stackexchange.com/questions/2593/…

  • Alas, there is no wildcard search in Gmail. I had hoped that something like to:bob+*@gmail.com would work, but it doesn't.

  • @AlEverett Wow, didn't know that. I saw it here: en.wikipedia.org/wiki/Email_address Jun 22 '12 at 8:45

You can try creating a filter for each of these foo+xxx@ addresses. Example:

Create a filter with on the To: field for foo+bar@domain.com OR foo+xxx@domain.com

Use the filter to apply a label and then you can just view emails under this label.

It's not very scalable if you have a lot of these types of address to filter on, but it will work if there are only a handful, and it will prevent you from having to run a script.


You could search for all emails addressed to bob@gmail.com (which would not return bob+anything@gmail.com), apply a label to them, and then filter for all email without that label.

This will also pick up emails that you receive at addresses other than bob, but if there are a limited number of such addresses you could also search for them and apply the same label.

    This isn't going to cover things like mailing lists where the recipient's email address doesn't appear in the To: header at all.

    @octern "search for all emails addressed to bob@gmail.com (which would not return bob+anything@gmail.com)": not true. I am guessing you didn't test it. I just tested this with (the equivalent of) "to:me", "to:myaddressstart@gmail.com", and even "deliveredto:myaddressstart@gmail.com", and they all returned all converstations with e-mails to me, with and without + addresses.

  • I seem to recall using this method in the past. It might have changed since then. Either way, this was never a great solution and now it's a nonfunctional one.

You can use -

It is used to exclude terms from your search.

Example: nerd -dinner

Meaning: Messages that contain the word "nerd" but do not contain the word "dinner".

Try it. You can read better on Google Support.

    -1 as this doesn't work for addresses, which is what the original poster asked. Aug 28 '12 at 15:18
