Send WordPress email through Resend
Modern transactional API with a clean dashboard. Sandbox keys, instant verification, and DKIM that just works.
Why pair Resend with NimblyMail
Resend built the transactional email API developers actually enjoy: clean dashboard, honest documentation, instant domain verification. NimblyMail connects it to WordPress in one paste — API key in, test email out — and layers on the queue, retries, and logging that make it production-grade for WooCommerce and membership sites.
- One-minute setup. Paste an API key and send. Domain verification inside Resend is genuinely instant for most DNS providers.
- Sandbox keys for staging. Resend’s test keys pair perfectly with NimblyMail’s Developer Sandbox for zero-risk testing.
- DKIM that just works. Resend’s three-record DKIM setup is verified by NimblyMail’s audit the moment you connect.
- Full observability. Every send logged with transcripts — combine Resend’s dashboard with WordPress-side proof.
Connect Resend in three steps
Create a Resend API key
In the Resend dashboard, create a send-only API key.
Paste into NimblyMail
Choose Resend as your mailer and paste the key — stored encrypted at rest.
Verify domain & test
Add Resend's DKIM records (the audit confirms them), then send a test email.
Resend requires three DKIM CNAME/TXT records per sending domain; SPF is handled via the Return-Path domain. NimblyMail's audit checks every record and links the exact values to publish.
