Using Tor, I can verify around ~60% of emails. Notably, the exit nodes can connect to Gmail/GSuite servers. So it's not that bad.

If Tor's exit nodes are blocked by a server, I fallback to Heroku, where I have right now 3 fixed-IP instances. And if I see that one of these also gets blacklisted, I would have it self-destruct and relaunch, Heroku assigns a new IP on each new instance.

Does Heroku reuse these IP addresses? Can someone get them after you?

I unfortunately don't know the answer to these two questions.
