});Teams that trust Relay with what matters
Everything that happens to every message
Every send has a timeline: accepted, delivered, opened, bounced. No support ticket to find out.
Domains in minutes
SPF, DKIM and DMARC checked for you, with the exact record to paste into your DNS.
Signed webhooks
Delivered, opened, clicked, bounced. Every event arrives signed, and retried.
Templates in markdown
Write the email like you write a README. The Outlook-proof HTML is on us.
Test mode
A key that pretends to send, so your test suite emails nobody.
Priority queues
Password resets and receipts go ahead of the newsletter.
Regions
São Paulo, Virginia and Frankfurt. Data stays where your customers are.
Deliverability you can read
Delivery rate per day, per domain and per template, without exporting a spreadsheet.
- 99.3% lands in the inbox
