If you are part of a #Mastodon server admin team here's a thing I hacked together yesterday: mastomsg https://codeberg.org/tante/mastomsg/

mastomsg allows you to send a DM either to a list of people or to all accounts younger than a certain timedelta (think: everyone who joined in the last 3 weeks). It's intended use is for example to send welcome DMs to people who just joined your server.

Nothing big but maybe it helps a few people. You can also install it via pip
`pipx install mastomsg`
