Hey Alexander, thanks for reaching out and great question! I’d love to hear the community’s thoughts on this, as I personally haven’t used Maildoso and wouldn’t want to take sides. That said, we do have an article co-written with one of Clay’s OG users, Eric Nowoslawski, that dives into this topic in more detail. I think you’ll find it super helpful!
