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

[#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.

[#2]

Hi,

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.

Thanks,

Hi,

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: <%= message.id %>
X-cust_DeliveryID: <%= delivery.id %>
X-cust_InstanceName: xxx_mkt_prod1
X-cust_IMSOrgID: <%@ include option='IMS_Organization' %>

Hope it helps

Regards
