There are tools that can check if your IP is on a blacklist [1]. Also, my experience with self-hosting email is that if you get people to email you first from their domain, and you reply to them, then you are not going to be blocked. Of course, this won't work if you send a lot of cold emails. [1] https://mxtoolbox.com/SuperTool.aspx |
