Notmuch is a very powerful tool for managing email, and I had an issue I have been dealing with for a little while now that I realized I could use Notmuch for, so I will go through the process I took to solve it in this article. I get loads of emails from colleges, and I wanted to separate those emails from everything else. Now, I’ve heard Gmail has this feature, but since I don’t use Gmail on my primary email address (unfortunately I have a Gmail account for school), I decided to figure out how to separate emails from colleges into their own mailbox in my mail client, Neomutt.

First off, when syncing mail, it should automatically tag new mail if it matches given queries, like in my case the words “college” and “university”. I have a script that downloads new mail every five minutes in a cronjob, so I added this:

# ~/.local/bin/mailsync
...
notmuch new # update notmuch db
notmuch tag +college "university" and in folder:xyz/INBOX
notmuch tag +college "college" and in folder:xyz/INBOX

Now every time mail is synced, it will be tagged appropriately. If you wanted to perform a Notmuch query for all mail that does not contain those phrases, you could type the following:

$ notmuch search not tag:college

This query can also be used in Neomutt by using virtual mailboxes like so:

# ~/.config/mutt/muttrc
...
set nm_default_uri="notmuch:///home/ben/.local/share/mail" # replace with your mail dir
set virtual_spoolfile=yes
virtual-mailboxes \
    "Inbox" "notmuch://?query=folder:xyz/INBOX and not tag:college and not tag:spam"\
    "College" "notmuch://?query=folder:xyz/INBOX and tag:college"\
    "Sent" "notmuch://?query=folder:xyz/Sent"\
    ...

This is a super helpful thing for me and it was an interesting learning experience setting this up. I hope this can be helpful to somebody. Thanks for reading!
