One API for every email your product sends
Transactional email, templates, broadcasts, live logs and signed webhooks, behind the same API your code already speaks.
Everything your product needs to send email. Four core capabilities, built to work together.
Send email with one call. The same request Resend takes, answered in milliseconds and queued so nothing is lost.

Keep the tools you already run. Resend SDKs, Svix webhook verifiers and plain HTTP work by changing one base URL.
Sixteen features, zero add-ons. Every plan gets the whole API.
01
Transactional API
Send one email per request, with attachments, tags and custom headers.
02
Batch sending
Up to 100 emails in a single request, accepted all-or-nothing.
03
Scheduling
Send later with a date or plain words like “in 1 hour”. Reschedule or cancel any time.
04
Idempotency
Retry safely. The same key returns the same email instead of sending twice.
05
Templates
Variables with fallbacks, draft and published versions, sent by id or alias.
06
Broadcasts
Send to a segment now or later, with per-contact personalization.
07
Contacts & segments
Custom properties, segments and CSV export for your audience.
08
Topics & preferences
Let people opt out of one kind of email on a hosted preferences page.
09
Suppression list
Hard bounces and complaints are blocked automatically, team-wide.
10
Webhooks
Signed events for every status change, retried with backoff for about a day.
11
Domains
DKIM, SPF and custom MAIL FROM, with automatic DNS checks.
12
Open & click tracking
Turn tracking on or off per domain.
13
API keys
Full-access or sending-only keys, optionally locked to one domain.
14
Teams & roles
Owners, admins and members, with single-use invite links.
15
Usage API
Read quota and usage programmatically.
16
Log retention
7 to 365 days depending on plan, deleted automatically after.
Sooner verifies your domain, sends anything you ask, and shows the delivery behind it
Verify your domain

Send anything
Use the SDK you already have, or plain HTTP. Sooner validates it, queues it and sends it in milliseconds.
Delivered to gmail.com
Check the delivery
Every email opens to its full timeline: accepted, delivered, opened, or exactly why it bounced.
Your reputation stays yours
Authenticated sending, isolated per team, with consent handled on every broadcast.
DKIM, SPF & DMARC on every domain
One-click unsubscribe built in
Bounces suppressed automatically
Works inside the SDK your code already uses
