Every send,
proven.
wemail is the transactional email platform built for teams who can’t afford a missed message. Send in milliseconds, ship in an afternoon, and prove every send — on infrastructure your engineers will actually trust.
Switch providers without rewriting a line.
Already using SendGrid, Mailgun, or Postmark? Keep your SDKs, method names, and types, point the host at our Bridge, and let your traffic flow through wemail — same code, better inbox placement.
Move over in an average of 47 seconds with zero downtime, while keeping the option to roll back instantly whenever you need it.
Change one line.
Not your codebase.
The Bridge works as a transparent layer between your existing provider setup and wemail, translating each provider's format to our v3 engine in just <10ms. Idempotency keys and deduplication headers stay intact, so retries remain safe without duplicate sends.
// before const sg = require("@sendgrid/mail"); sg.setApiKey("SG.abc123…"); // after — one config line const sg = require("@sendgrid/mail"); sg.setApiKey("afn_live_pK7…b9aF"); sg.setHost("https://api.wemail.io/bridge/sendgrid");
Six jobs. One platform that does them properly.
From password resets that need to arrive in seconds to the tools that keep your messages out of spam, wemail brings the essential parts of email delivery into one platform. Every capability is built to perform at scale — and every result can be measured.
Email your users actually receive — in milliseconds.
Send time-sensitive transactional email through one fast email sending API, with sub-100ms queuing and idempotency keys that make retries safe. Reach up to 5,000 recipients in a single call while personalizing each message with individual merge variables.
- Low-latency accept time-to-accept, anywhere in the world
- Idempotency keys make retries safe by design
- 5,000 recipients per call with merge variables
- Automatic, exponential retry with dead-letter visibility

- CLI to tail, replay and debug in real time
- Sandbox keys hit a parallel pipeline, zero risk

- Real-time analytics down to the individual message
- Stream to Kafka, SQS, Snowflake — no glue code

Validate every address before you send.
Protect your sender reputation with real-time and bulk email verification powered by DNS, SMTP, and AI-based scoring. wemail identifies invalid, disposable, and risky addresses before sending, helping you keep your lists cleaner and reduce unnecessary bounces.
- 8-step pipeline — syntax, DNS MX, SMTP mailbox, catch-all, disposable, role-based, spamtrap, risk scoring
- Bulk CSV — upload up to 50K addresses, download segmented results (valid, invalid, risky)
- Real-time API — single-address verification in under 2 seconds via REST
- Allow/block rules — customer-defined domain and email filters applied before verification

Proof of dispatch that anyone can verify.
Every certified send issues a signed, timestamped Proof-of-Sending certificate. The other party verifies it at wemail.io/verify — no account, no support ticket, no need to trust us.
- Signed certificate — HMAC-SHA256 over the message, recorded in an append-only EU registry
- Public verification — recipients confirm it at wemail.io/verify with no account
- Everywhere it's needed — attached to the send, downloadable in the console, fetched over the API
- Dispute-ready — settles “we never got it” for invoices, regulated notices and audits
