You build the thing. We send the email.
Notify is the building block for sending the email your product creates when something happens* — password resets, onboarding, receipts, alerts.
*Industry folks call that transactional email. We just call it email.
Block 1
Your app
Whatever you're building.
Block 2
Notify
One piece. Email.
Block 3
It just works.
Four steps. Then you're done.
The smallest path from zero to email in production.
01
Get an API key
Sign up. Copy a key. That's the hard part.
02
Send a test
Hit the API. See a real email land.
03
Verify your domain
Add DNS records. Then send from your address.
04
Ship it
Watch logs and webhooks. Keep building.
Try it for yourself
Edit the email. Hit send. Open it in the inbox.

Ready to send for real?
Get an API key. Hit the endpoint. Keep building.
Just the bits you need
We don't do templates, campaigns, or contact databases. That's kind of the point.
Email API
One endpoint. Send email from your app with a simple request.
Verified domains
SPF and DKIM so production mail authenticates. Required once, then forget it.
Delivery logs
See what happened after every send — delivery, opens, and clicks.
Webhooks
Push events to your app so your product can react when mail lands or bounces.

Differ

100,000+ writers notified
Obsurfable

Circuit

Frequently asked questions
What is Notify?
Notify is email for whatever you’re building. Send password resets, onboarding, notifications, and receipts with one API call. Watch delivery with logs and webhooks. No template builders: you write the HTML.
What is transactional email?
Email your product sends when something happens — a signup, password reset, receipt, or alert. Not newsletters or marketing campaigns. Notify is for that first kind.
What kinds of email can I send?
Account verification, password resets, product notifications, receipts, and similar messages triggered by your app.
Do I need to verify a domain?
Yes for production sending from your own address. Get an API key, verify SPF/DKIM, then send.
Is there a free plan?
Yes. Free includes 1,000 emails per month, 1 domain, and 48-hour logs. Paid plans start at $10/month for 10,000 emails with permanent logs and webhooks.
