Domain Management
Configure your receiving address and verify a custom domain for outgoing email
Use Settings → Domains to find your receiving address and configure a custom domain for outgoing email. Sending-domain verification and customer email-domain matching serve different purposes.
Receive customer email
The Generated Email Address card shows your workspace's receiving address. Copy the address shown in Core; do not construct it from your workspace name.
Give customers that address directly, or forward mail from your existing support mailbox to it. The generated address works without a custom sending domain. Replies to Core ticket emails return to it.
Add a custom sending domain
- Open Settings → Domains and select Add Domain.
- Enter the domain, such as
company.com, without a protocol. Add optional notes and save. - On the domain card, choose View DNS Setup Instructions.
- Copy each record's Type, Name/Host, and Value into your DNS provider.
- Select Verify DNS after the records are available.
- Once verified, choose Set as Primary to use it for outgoing email.
Use the values Core shows for SPF, DKIM, and DMARC. This setup does not require changing your mailbox's MX records. DNS changes may take time to become visible; retry verification if the records are still pending.
Manage domains
You can keep several custom sending domains, but only one is primary. Use the domain card's controls to verify, set the primary domain, or remove a domain you no longer use. The generated receiving address remains the place to receive ticket email.
Customer matching
A company's Email domains identify which customer an incoming sender belongs to. Manage those on the company record, as described in Company Management. Adding or verifying a workspace sending domain does not replace that setup.
Troubleshooting
- Verification stays pending: compare every record's type, host, and value with Core's instructions. Check whether your DNS provider automatically appends the domain to the host name.
- Tickets are not created: verify forwarding to the exact generated address, then review the Email Received automation.
- Wrong sending domain: confirm the intended domain is verified and primary.
