Purpose-built SMTP relay for telephony
vmailto.email is a hardened SMTP relay built for PBXs and telecom systems — voicemail, call logs, fax, and alerts delivered every time.
No spam. Early access pricing for signups.
The problem
Microsoft 365 and Google Workspace increasingly reject unauthenticated SMTP from legacy phone systems.
Corporate firewalls block unfamiliar sending IPs. Your self-hosted relay gets caught in the crossfire.
No bounce. No alert. The message just vanishes. Users think their voicemail is broken — you get the call.
Shared hosting and self-managed servers inherit spam reputation. One bad actor and you're on an RBL.
How it works
We relay outbound mail through trusted infrastructure — Amazon SES by default. Your PBX authenticates with a per-device credential. No shared passwords, no inbox exposure, no complexity.
Compatible systems
Pricing
No inbound mailboxes. No IMAP or POP exposure. Send-only by design. Per-device credentials with rate limits and immutable audit logs.
