Automatically tag email according to sender?

I have hundred of senders whose emails need to be tagged with one of three tags when they arrive. I can make one or more rules that have hundreds of senders listed but that’s laborious. Plus new senders would be added daily. Some other email clients have a button on each email you can simply tap and add that tag to all subsequent emails from that client. Does that exist in this app?

Gmail does this automatically with its three categories of emails and that would work for me, too, except I’m not on Gmail but 13 regular IMAP accounts.

Any idea how to make something work in Emclient? Thanks.

The only way you can automatically assign a tag to incoming messages is through a Rule.

Unfortunately the only way to add senders to the Rule is to create the Rule or edit an existing Rule, and add them manually. Sorry.
