Email infrastructure built the way
developers actually want it
Sendry is a full-stack email platform: send transactional emails via REST or SMTP, receive inbound messages, run broadcast campaigns, monitor deliverability, and observe every event, all from one API and dashboard.
- Uptime target
- 99.95%
- Official libraries
- 7 SDKs
- Send paths
- REST + SMTP
Our mission
Make sending, receiving and understanding email as simple as one API call, without giving up the control that production teams need.
We build for the engineer who has to be paged when the password reset does not arrive, and for the marketer who needs to know which campaign actually landed. Same engine, same data, one place.
Values that shape every release
Developer-first
Great DX is a product feature, not an afterthought. Every API decision is made with the developer experience in mind.
Reliability by default
Queue-backed delivery, automatic retries, and 99.95% uptime mean email that lands, not email that might land.
Transparent pricing
Simple tiers, usage-based overages, and no vendor lock-in. You know exactly what you pay and why.
How Sendry works
The architecture behind Sendry is designed for throughput, observability, and correctness.
Transactional-first API
Sendry is built around reliable transactional email with clean REST endpoints, batch sending, template rendering, and per-email status tracking.
Two send paths
REST API or SMTP relay: same delivery engine, same tracking and analytics. Integrate however your stack already works.
Inbound processing
Inbound emails are verified, parsed into structured records, and optionally forwarded to your webhook endpoints, closing the loop on two-way communication.
Queue-backed delivery
Email, tracking, and webhook processing run through BullMQ workers backed by Redis so API responses stay fast even under heavy load.
Scheduling & cancellation
Queue emails for future delivery with a single `scheduled_at` parameter. Cancel any queued send before it goes out.
Operational controls
Verified domains, scoped API keys (full / sending / read-only), suppression list filtering, and HMAC-signed webhook delivery out of the box.
Built for every team, not just engineers
Whether you are shipping a transactional welcome email or running a 100k-recipient campaign, Sendry has you covered.
