On a computer, you can install the Proton bridge, and then access mail using you preferred mail client. I highly recommend using a custom domain as it has the advantage of being able to take it with you if you decide to change email providers, and avoids the need to update email addresses on all your accounts ever again.ĭue to the encryption, Proton mail does require that you use their mobile app, not the native mail app on your device.

So far, no issues being flagged as spam or not being accepted when setting up accounts. I have been using Proton mail with a custom domain as my primary email for a year now and it's been working very well. As long as whatever mail service you choose has all the correct DNS Security settings and certificates in place, there shouldn't be an issue. I've never had a problem getting mail from Fidelity, Alliant, Ally, etc. They offer all the services you could want in a mail system, allowing you to register multiple domains on your account, create aliases, calendar services via webcal, etc. I've used for my mail service for well over a decade now for DW and I, never used gmail, yahoo, etc (Ran my own mail services for my personal domain previous to that but got tired of the upkeep). Was curious if anyone uses something like that and had any issues such as just flat out not being accepted, or being flagged as spam, or locking out of accounts etc with financial accounts as a login using something other than the big players gmail/yahoo/outlook etc. Looking to move away from google to a paid email service like proton mail which allows you to have custom domains setup or various addresses.

Protonmail use own domain
