Infrastructure tuned obsessively for deliverability and speed — measured across billions of sends.
A complete sending platform — from authentication to analytics — without the enterprise bloat.
Automatic SPF, DKIM, and DMARC alignment, dedicated and shared IP pools, smart warm-up, and real-time blocklist monitoring keep your reputation pristine so messages reach the inbox — not the spam folder.
A globally distributed sending network relays mail in under half a second, with intelligent queueing and retries built in.
Track opens, clicks, bounces, and spam complaints live. Drill into every event with webhooks and exportable logs.
TLS 1.3 in transit, encryption at rest, scoped API keys, SSO, and SOC 2 Type II compliance out of the box.
Drop-in SMTP credentials work with any stack, or use our clean REST API and SDKs for Node, Python, Go, Ruby, and PHP. Templating, scheduling, batch sends, and idempotency keys are all first-class — with docs that don't make you guess.
From signup to your first delivered email in under five minutes.
Add a few DNS records and we'll auto-configure SPF, DKIM, and DMARC. Our checker confirms alignment in real time.
