Free address

Choose Free address, pick an available domain, enter a username, and optionally assign an assistant. Availability is checked while you type; the final name is reserved when you select Create address. Names are unique within each domain and remain reserved to your workspace after deletion. Use 3–32 lowercase letters, numbers, dots, hyphens or underscores; start and end with a letter or number. Reserved names and consecutive dots are not allowed.

​
Custom domain

Custom domains are available on every plan, including Free. Each new connection is paid in workspace credits. Open the Custom domain tab and enter your domain. Use a dedicated subdomain such as mail.example.com to preserve an existing mail setup. Select Connect domain and confirm the displayed credit price. The connection fee is deducted before the CNAME and MX records are shown. Add those records at your DNS provider, then select Verify DNS. Verification and retries are free. Deleting a domain does not refund credits; every new connection, including reconnecting the same domain, costs the current price. Existing connections remain free until deleted.

​
Addresses and defaults

After verification, create addresses on your domain and assign an assistant to each. Set a sender name per address or use Default Display Name and Default Signature for the workspace. The signature supports {agent_name}. Only workspace owners and admins can manage the channel. Available platform domains depend on the workspace. One email address capacity applies to all addresses across platform and custom domains, including inactive addresses. Existing addresses keep working when capacity is reached; delete an unused address or increase capacity to create another.

​
Billing and history

Creating a hosted address is free; sending and receiving consume workspace credits at the current rates. Check the displayed custom-domain price before connecting. Conversations appear in Email history. Outbound acceptance does not guarantee inbox delivery.

​
Automation

Read options first, select a hosted domain, check a name, then create the address. For a custom domain, confirm the current credit amount when connecting, configure DNS, then verify without another payment. Read the current price instead of hardcoding it.
