Local mailing lists in Thunderbird

I’ve encountered this situation multiple times: I’m part of an informal group with quite a few people, and at some point, I need to send an email to all of them. However, I don’t want to “Reply All” to the last email in the thread, as it’s about a completely different topic. Copying and pasting all the email addresses every time is tedious—so what’s a better way?

Solution: You can create a “local” mailing list on Thunderbird, which acts as an alias for a set of recipient addresses. Just go in the adress book, create a new mailing list, give it some name, and list the adresses. Now every time you need to write to this group of people, you can simply send it to “name of your list”.

This is probably obvious to most people, but after years of manually copying addresses, I’m glad I finally looked for a smarter solution.
