Setting up a custom header on your campaign

Adding a custom header to your emails can be a useful tool for helping recipient email clients differentiate between a spam email and a genuine email. They are also useful for allowing customers to unsubscribe from your emails rather than marking them as spam with their email client, in turn impacting your deliverability reputation.

Adding a custom header to your newsletter

A custom header can be set up on a per campaign basis by visiting the Advanced section at the bottom of your newsletter campaign and clicking Add header.

Using a list-unsubscribe header

Adding a list-unsubscribe email header allows customers to opt-out of receiving your emails rather than clicking on an unsubscribe footer or marking an email as spam with their email client.

This can be added as a custom header in your Vero campaign by using List-Unsubscribe: <mailto:unsubscribe@domain.com>,<{{url.unsubscribe_link}}>.

The mailto: address (ie. unsubscribe@yourdomain.com) should be a valid email address that you control. It must be monitored, and emails sent to that address will need to be unsubscribed.

Some clients do not honor the unsubscribe URL portion of the header and will only send the email, so we do require that both options are included.

If you choose not to use the Vero automated unsubscribe link used above, please note that larger clients like Google and Yahoo do require that the link used to unsubscribe the customer occurs in one click and cannot contain an extra step to do so.
