If you want follow-up fully done for you and do not mind the emails going out through a sending platform rather than your own address, SphereSync delivers that convenience. The trade is deliverability and authenticity: mail from a shared sending infrastructure looks like marketing because it is, and replies do not come back into your real threads. With Cadento the email is literally yours: your address, your Sent folder, your reply threads.
