Feature Request: Support for other Masked Email providers

I'd like to second the request for other masked/unmasked email providers, ESPECIALLY ones not based in 5Eyes countries and who have stellar reputations for enhanced support for end-to-end encryption.

It's surprising and disappointing that 1PW, despite having a great reputation (in spite of its 5 Eyes country ops base) doesn't adequately support integrations with the most reputable paid encrypted email, encrypted voice call, encrypted text, email masking, and VPN providers.

Once that starts seriously happening, I can start moving my digitally-vulnerable friends & family members who I'm designated geek for onto higher-privacy/security services en masse.
