I migrated from Campaign Monitor to @buttondown today, and I'm pretty happy about it.
I feel like I may have been the last person on CM. Buttondown didn't even have an option for it to pick from in the list of ESPs to choose from 😆
Now all of my email newsletters like https://coywolf.com/newsletter/ and welcome emails for my apps like https://recollect.fyi and https://get.essential.support send from Buttondown. 🙌
