Sending domain

Email Marketing

A sending domain is the domain or subdomain your marketing emails are sent from, which carries their authentication and reputation.

## What is Sending domain?

Your sending domain is what inbox providers judge. Many brands send marketing from a **subdomain** such as mail.yourbrand.com: customers still see the brand, and the main domain your everyday mailbox depends on keeps a separate reputation. **Setup:** prove you own the domain, add SPF, DKIM and DMARC, add routing records for replies and bounces, then warm it up. **In SmartyTap,** you add the sender domain under Settings, Email Setup; SmartyTap fills in the reply, return-path and tracking subdomains and checks each record.

## Example

A store keeps hello@yourbrand.com for customer replies and sends campaigns from news@mail.yourbrand.com.

## Why Sending domain Matters

A separate, well-kept sending domain protects your everyday email if a campaign ever goes wrong.

## Sending domain FAQ

Should I send from my root domain or a subdomain?

A subdomain is the safer choice for marketing. It keeps campaign reputation apart from your main mailbox.

Does a new sending domain need warming up?

Yes. Start with small sends to engaged contacts and grow volume over a few weeks.
