What Users Say
ImprovMX
I love this product. It really let's me use my single Gmail account with all my domains and I've found it to be reliable, gets through SPAM, and is so affordable. Highly recommend.
Great product. Thoroughly enjoyed onboarding, they clearly understand UX. And a very generous free plan.
ProtonMail
Protonmail makes the mail service secure. We need more products like this. However, it might be more cost effective.
ProtonMail is the best alternative to Gmail I know. Their commitment to privacy, the free tier, and the modern UI make it a no-brainer when looking for a valid email provider.
Great email service. VPN has some interoperability issues with things like pocketcasts.
