What problem does it solve?

This Skill streamlines adding, verifying, and managing custom sending domains in Resend so teams can enable authenticated email sending and resolve deliverability issues without manual API calls and DNS guesswork.

Core Features & Use Cases

  • Add and configure domains: Create a sending domain and obtain the exact DNS records you must add at your DNS provider.
  • DNS record guidance: Receive SPF, DKIM, MX and optional DMARC values and instructions for common providers and edge cases.
  • Verification and management: Trigger verification, check propagation and status, list active domains, and remove domains when no longer needed.
  • Use Case: Isolate email reputation by adding a subdomain like send.example.com, add the provided records in Cloudflare or Route 53, verify ownership, then send from the verified address.

Quick Start

Use the domains skill to add send.yourdomain.com, copy the SPF DKIM and MX records into your DNS provider, and trigger verification with your Resend API key.

FAQPage Schema
How do I add a custom sending domain to Resend and get the DNS records?

To add a custom sending domain to Resend, create the domain to retrieve exact SPF, DKIM, and MX records that must be added at your DNS provider for verification and authenticated email sending.

What DNS records do I need to verify a Resend sending domain?

Verifying a Resend sending domain requires adding SPF, DKIM, and MX records as TXT entries in your DNS settings, and optionally configuring DMARC values to resolve email deliverability issues.

Can I use a subdomain like send.example.com for Resend email deliverability?

Using a subdomain like send.example.com for Resend email deliverability isolates your email reputation, requiring you to add the provided DNS records and trigger verification with your Resend API key.

Do I need a full_access Resend API key to manage sending domains?

Managing Resend sending domains requires a Resend API key with full_access permission to add domains, trigger verification, check DNS propagation status, list active domains, and delete domains.

How do I check if my Resend domain DNS records have propagated?

To check Resend domain DNS propagation, trigger verification after adding the required SPF, DKIM, and MX records to your DNS provider, then check the status to confirm ownership and enable sending.

Why is my Resend domain verification not working?

Resend domain verification fails when SPF, DKIM, or MX records are incorrectly added or have not fully propagated in your DNS settings, requiring you to confirm record values and re-trigger verification.
