Hi Team,

A Contact entity in CRM, has a field called as "Send Marketing Materials". The logical name of this field is "donotsendmm". It is a type “two option” field with values are "Send" and "Do Not Send".

This field is displayed in the Contact main form under the section "Marketing Information".

A contact let's say "Contact ABC" can be part of more than one marketing list. Let's say the "Contact ABC" is part of 3 marketing lists: "ML 1", "ML 2" and "ML 3". Now I can create 3 quick campaigns on the above marketing lists. Let's say I create quick campaigns "QC 1" on "ML 1", "QC 2" on "ML 2" and "QC 3" on "ML 3". All these quick campaigns are email campaigns and have “unsubscribe link”. These quick campaigns are for different reasons: "QC 1" is for advertising homes to buy. "QC 2" is for advertising homes to rent. "QC 3" is for advertising new land selling.

The contact "Contact ABC" receives an email from quick campaign "QC 1". Contact doesn't want to receive any emails on homes to buy as this contact is only interested in buying new land. This contact unsubscribes from this email link. This will set "Send Marketing Materials" == “Do Not Send”.
The problem is this will unsubscribe "Contact ABC" from all the marketing lists. The reason being as the setting is on the contact profile field "Send Marketing Materials" which is now set to "Do Not Send".

Is there a way that when we add contacts to marketing lists, we actually create a landing (intermediate) entity? This entity will bind contact and marketing list relationship. In this binding entity we should have “contact id (contact lookup)”, “marketing list id (marketing list lookup)” and a field "Send Marketing Materials". Now if "Contact ABC" unsubscribes from the email from quick campaign "QC 1", this means the contact will only be unsubscribed from that marketing list "ML 1" in future. This unsubscribe will set the field "Send Marketing Materials" == “Do Not Send” on the binding (landing) entity which has “contact lookup” == “Contact ABC” and “Marketing list lookup” == “ML 1”.

The idea of an intermediate entity (landing entity) can make this marketing campaign and unsubscribe experience quite flexible.

Thanks.
