From SMTP relay to reputation management — everything your application needs to reach the inbox reliably.
A fully managed SMTP relay that accepts your outbound email and delivers it to the recipient's inbox. Connect any application, framework, or mail library using standard SMTP credentials. We handle queuing, retries, and delivery to all major providers.
Every outbound email is automatically signed with DKIM using our shared infrastructure key. Your sending domain only needs a single CNAME record — no key management on your end. SPF and DMARC are configured at the base domain level and automatically inherited.
Continuing to send to invalid addresses damages your sender reputation. We automatically classify every bounce, suppress hard-bounced addresses immediately, and provide full visibility into your bounce rates and suppression list.
Track delivery status for every message in real time. Drill into per-domain delivery rates, identify patterns in deferrals or bounces, and export logs for compliance or debugging.
