Verified sending domains
Use a root domain or dedicated subdomain you control, with SPF, DKIM, DMARC and Return-Path verification.
Application email infrastructure
Airmail
Transactional email infrastructure built for developers. Send through REST or SMTP, verify your domains and follow each message from acceptance to delivery.
Developer beta. No payment to start. Verified domain and manual sending approval required.
REST + SMTPMessage ExplorerProvider-aware queues
Built for application traffic
Airmail separates durable API acceptance from provider delivery capacity, then gives each tenant a verified identity and a traceable message lifecycle.
Durable provider queues
Messages remain durable while provider-aware pacing protects delivery from concentrated bursts.
Idempotent sends
Retry the same logical request safely with one stable Idempotency-Key.
Lifecycle visibility
Follow accepted, queued, submitted, delivered, deferred, failed and bounced states.
Tenant isolation
Domains, API keys, usage, messages and suppressions are scoped to one tenant.
Delivery analytics
Understand delivery trends, provider delays and domain health, then drill down to the message that needs attention.
One HTTPS request
Send from your server
Use standard HTTP from any backend. API keys remain server-side and raw keys are shown once.

From domain to delivery
