Everything you need to send well
Fast API & SMTP
Accept-and-queue in milliseconds. Send over a versioned REST API or standard SMTP relay.
Domain authentication
Guided SPF, DKIM and DMARC setup with managed keys you rotate without touching DNS again.
Verified senders
Sender identities are tied to domains you actually own — no spoofing your customers.
Real analytics
Delivered vs. deferred vs. bounced, complaint and delivery rates, per-message event timelines.

HMAC-signed events with exponential-backoff retries, replay and idempotency built in.
Reputation protection
IP pools, warmup, suppression lists and abuse controls keep one bad sender from hurting the rest.

Frequently asked questions
Do you support both API and SMTP?
Yes — a versioned REST API and a standard SMTP relay, with the same authentication, sending policy and analytics.
How is deliverability handled?
Managed DKIM, enforced SPF/DMARC alignment, shared and dedicated IP pools with warmup, and automatic suppression of hard bounces and complaints.
Can I bring my own domain?
That is the only way to send — every sender identity must belong to a domain you have verified.
