Forward Email

The defining trait here is transparency: the code that processes your mail is the same code running on their servers, so there is nothing proprietary to trust blindly. A first independent security audit by Cure53 was published in 2026. Free alias forwarding for custom domains makes it easy to try, and paid plans unlock full mailboxes with IMAP support. The trade-off for choosing a US-based provider is that US legal jurisdiction applies, which is a real consideration compared to Swiss or German alternatives. Self-hosting removes that concern entirely, though it requires you to manage your own mail server infrastructure.
