unsubscribe header

[#1]

How can i include a header in emails?

Is there any way to bulk update the templates in email to incorporate the headers for any future emails that are sent out.

Hi,

Add this to smtp header

Precedence: bulk

List-Unsubscribe: <mailto:<%= provider.errorAddress !='' ? provider.errorAddress:delivery.mailParameters.errorAddress %>?subject=unsubscribe<%=escape(message.mimeMessageId) %>>

For bulk upload, you can try to do it in a JS. Moving forward you can add a typology rules to add it automatically to all deliveries.

Thanks,

David
