vs $0.001-0.01 per email with SaaS
Single API call, individual tracking
Your infrastructure, your data
Crypto-shredding for true erasure
Everything you need for production transactional email, without the enterprise price tag.
Manage email templates like code. Draft, preview, publish. Full commit history with instant rollback. Never lose a template again.
True GDPR compliance, not just checkboxes. Per-user encryption keys mean deleting a key makes all user data permanently unrecoverable.
Send up to 1,000 emails in a single API request. Each email gets individual variable interpolation and tracking. Perfect for newsletters and notifications.
Know exactly what happens to every email. Delivered, bounced, failed - get notified instantly with HMAC-signed payloads and automatic retries.
Perfect for SaaS and agencies. Complete isolation between tenants with separate API keys, providers, templates, and encryption keys.
SMTP or Microsoft Graph API - use whatever works for your infrastructure. Configure multiple providers per tenant with automatic failover.
Drop-in SMTP server for applications that prefer SMTP over HTTP APIs. Same authentication, same templates, same queue - just SMTP.
Queue emails for future delivery with RFC3339 timestamps. Perfect for time-sensitive notifications, reminders, and scheduled campaigns.
Built-in tools to keep your sender reputation healthy. Rate limiting, suppression lists, email validation, and List-Unsubscribe headers.
