If you are a Tor user and have the known issues with many E-Mail services (blocking, captchas, …) then you can try out https://cock.li/
Please don’t advertise other services on this forum. I almost banned you as an ad bot…
I am not a bot 
Because the tribler Software here is about tor routing, many user probably also use tor. Thus they know those many services that block tor users. I liked to tell about a rare email-service that is free and not blocking tor users - in the off-topic section. I cant earn any capitalistic money out of recommending this service 
PS: I am the “new user of the month” from august 2020. Would be not that nice to get blocked https://forum.tribler.org/badges/44/new-user-of-the-month
