Sender Identities

A Sender Identity is a verified email address (e.g., noreply@yourbusiness.com) that staff members can use as the "From" address when composing emails. A staff member needs access to at least one identity to send email through QuantixOne.

What Is a Sender Identity?​

A sender identity is an email address on one of your verified domains. Any staff member granted access to it can select it as the From address in the email composer — the recipient sees the email as coming from that address.

Domain must be verified first

You cannot create a sender identity using an unverified domain. Complete Domain Setup before adding any sender identities.

  1. Go to Settings → Channels → Email.
  2. Click the Settings tab.

The Settings tab lists your verified Domains & Email Identities, and an Email Identities table below it.

Adding a Sender Identity​

  1. Click Add Email.
  2. Choose the verified domain, then enter the local part of the address — e.g., enter noreply to create noreply@yourbusiness.com.
  3. Click Save.

Managing Access to an Identity​

Every sender identity starts with no one able to use it. To let staff send from an identity:

  1. On the identity's row, click Manage Access.
  2. Check the box next to each staff member who should be able to send from this address.
  3. Close the dialog — access is saved as you check/uncheck each staff member.

A staff member can be given access to more than one identity — in the email composer, they choose which one to send from using the From dropdown.

Deleting a Sender Identity​

Deletion removes the address from all staff immediately

Deleting a sender identity removes it from the From dropdown for every staff member who had access to it.

Click the Delete (trash) icon on an identity row to remove it.
