Built for deliverability. Engineered for developers.

Every feature ships as an API-first primitive — fully observable and production-ready from day one.

Deliverability

Your reputation, fully protected

We handle the hard parts — DKIM signing, SPF alignment, DMARC policy enforcement, and automatic hard-bounce suppression — so your sender score stays pristine.

  • DNS verification wizard for SPF, DKIM, and DMARC
  • Automatic bounce and complaint suppression list
  • RFC-compliant List-Unsubscribe and one-click unsubscribe
  • CAN-SPAM compliant physical address footer injection

Streams use independent IP pools — one never harms the other.

Message Streams

Protect your transactional IP

Promotional campaigns generate complaints. Transactional emails must reach the inbox. WebMail isolates them on separate IP pools so a bad batch never burns your receipts stream.

  • Two streams: transactional and promotional
  • Per-stream analytics and deliverability dashboards
  • Wrong-stream sends flagged in the dashboard automatically
World-class support

Experts, not bots

Every plan includes real human support from engineers who actually understand deliverability, RFC compliance, and edge cases.
