# Setting up a Mailtrap sending domain ## Overview You must add and verify a domain you control before live sending. Mailtrap shows **every DNS record** required for that domain in the **UI**: **add the complete set** as given (do not cherry-pick). After DNS verifies, complete the **compliance** step if requested. **Subdomain vs root:** add the **exact** hostname you will use in the From address. If you send from `notifications.mycompany.com`, add that **subdomain** as the sending domain—not only `mycompany.com`, unless you truly send from the root domain. For step-by-step clicks at common hosts, open the matching guide on [Sending domain setup](https://docs.mailtrap.io/email-api-smtp/setup/sending-domain.md) (Cloudflare, Route 53, etc.) and follow it alongside the live **UI** values. **Related skills:** `mailtrap-sending-emails` (after domain is ready). ## When to use - New **Sending Domains** setup, stuck verification, or compliance questions - DNS at Cloudflare, AWS, Google, Namecheap, GoDaddy, DigitalOcean, etc. ## When not to use - Sandbox-only testing without a custom domain (see `mailtrap-testing-with-sandbox`) ## Authorization The Sending Domains API calls below need `Autho

From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
