I thought so too because 364 days of the year I will average 0 sent but that one other day I might have a conversation and I don't want my messages to be blocked when I reach 21.
Being a current user of Migadu: I’m not sure what they’ve written there is actually correct. When I’ve gone over the outgoing message limit, I’ve received no warning, no 25% margin, and the messages were just dropped, not deferred. I just received an email telling me I had exceeded my account limits.
Do they do a good job of getting into the inbox and staying out of spam? That’s the main reason I stay on gmail, it’s so hard to find a provider with shared IPs that reliable land in the inbox.
I use a wildcard domain for this. Every site gets its own address. Each whatever@ gets a mailbox on the left side of the screen, which you can individual hide or turn off automatic fetching if you want. Keeps things clean and you don't have to worry about spam so much.
