Inbox - Filter by subject line contains

Hey all! I'm looking for a way to filter the inbox to show these two formats:

  • Sbject line contains [IWE]
  • Subject line does not contain [IWE]

Since I am using an email warmup service, I am getting like 300+ warmup emails per day collectively, which all get's bcc'd to Pipedrive. This easily drowns the relevant incoming mail, and I would like a way to filter those warmup emails. All of these emails will have the end tag "[IWE]" in the end of the subject line, so trying to figure if there is a way to filter by subject contains?




  • Does anybody know where to research this? I cannot see this is possible but it seems like a pretty simple feature
