Sample input
Help me set up notifications.myapp.com as a sending domain in Mailtrap and show me the DNS records I need to add to Cloudflare.
Sample output
I've initiated the setup for 'notifications.myapp.com'.
To verify this domain, add these records to Cloudflare (set to 'DNS only', no proxy):
- SPF (TXT): v=spf1 include:_spf.mailtrap.io ~all
- DKIM (CNAME): mailtrap._domainkey.notifications.myapp.com -> dkim.mailtrap.io ...[additional records]

About This Skill
Walks agents through the full domain verification flow in Mailtrap: adding a domain via UI or API, retrieving the exact DNS records to publish, adding them at common DNS providers (Cloudflare, Route 53, Google Cloud DNS, GoDaddy, Namecheap, DigitalOcean), troubleshooting propagation delays, and completing the compliance step. Also covers subdomain vs root domain decisions, proxied DNS caveats, and automation via the Sending Domains API.
Use Cases
- Provision new sending domains programmatically via Mailtrap API.
- Debug SPF/DKIM verification failures triggered by DNS proxying.
- Generate provider-specific instructions for Cloudflare, Route 53, and GoDaddy.
- Verify DNS propagation status for custom email hostnames.
Known Limitations
- Cannot automate UI compliance steps.
- DNS propagation timing is outside agent control.
- Requires existing domain ownership and provider API access for full automation.
