news.example.com sends email under its own name, so
marketing mail never affects the reputation of mail sent from example.com.
Manage subdomains from the Subdomains tab on a domain’s detail page.
Prerequisites
- A domain you have verified or registered with Bizzy. A subdomain belongs to that domain, so you don’t verify it separately.
Purposes
Each subdomain has a purpose. It decides what the subdomain does and which email addresses can use it.
Transactional and marketing subdomains don’t receive mail, so they never
conflict with a mail host such as Google Workspace or Microsoft 365 that already
serves your domain. A marketing email address can only use a marketing
subdomain.
Adding a subdomain
- Go to Domains, open the domain, and select the Subdomains tab.
- Click Add subdomain.
- Enter the Name — the part before your domain, such as
news. - Choose a Purpose.
- Click Add subdomain.
Enabling email
Click Enable email on the subdomain’s row. The status moves to Setting Up, then to Active once the subdomain’s records verify.- Registered through Bizzy — the records are added for you.
- Verified (DNS hosted elsewhere) — open the subdomain, select Settings, and add the records listed there at your DNS host. See Email deliverability.
Deleting a subdomain
Click the delete icon on the subdomain’s row, then confirm. Its email setup is removed; the parent domain is unaffected. Delete a domain’s subdomains before you delete the domain itself.Next steps
