I am currently switching over to using "tagged" gmail addresses - for example, using firstname.lastname@example.org for my amazon email, email@example.com for my newegg account, etc. However, because I am sure I won't remember to change all of my existing email subscriptions, I want to automatically label all emails with a "uncategorized" label for further sorting. When I create a filter for just firstname.lastname@example.org, all of my emails show up, and since "+" is a reserved symbol I can't just search for that. Regex also does not seem to work. Has anyone else had/fixed this problem? Thanks!
Edit: I am trying to create filters for emails without tags (ex: email@example.com). Simply searching for "firstname.lastname@example.org" does not work as it returns all emails received.
