Proton Mail

Proton Mail is an email service centered on encrypted storage and private communication. Its inbox tools include labels, folders, filters, scheduled sending, and options for importing mail and contacts from another provider.

Messages between Proton users are end-to-end encrypted; protecting mail sent to other providers can require options such as password-protected messages or supported PGP. This distinction matters when choosing a communication method. Individuals and businesses can select account options for addresses and domains, with the current plan determining the included capacity and administration tools.
