How to implement SMTP headers in email deliveries to create unsubscribe links


Level 1

This is a discussion space for a whitepaper I'm putting together on the approach to best practices in implementing SMTP unsubscribe headers in email deliveries.

The straightforward approach is to set it in the delivery template, 'list-unsubscribe' etc.

Using a control typology can be preferable if you're in an environment where users can't be trusted, as part of a broader set of restrictions.

The support has set up  the following in our delivery templates:

Precedence: bulk

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

TenantHeader: <%@ include option='DmRendering_cuid' %>

Affinity: <%= delivery.scheduling.IPAffinity %>

X-cust_MessageID: <%= %>

X-cust_DeliveryID: <%= %>

X-cust_InstanceName: xxx_mkt_prod1

X-cust_IMSOrgID: <%@ include option='IMS_Organization' %>


Hope it helps
