We need to send out email campaigns, but in order to get a response from them, we want to have a URL with a unique ID embedded in it. Ideally this would be a message ID that links either to the lead, account or contact that the lead is sent to.
Embedding the name isn't really an option as it needs to be URL-encoded.
For example we want to have a "yes, I am interested" and "no, stop sending me these emails" link that the recipient simply clicks on. That will be a URL to a page that we set up that will action their request.
However, I don't see a suitable variable in the documentation.
Does one exist?
Any suggestions anyone?
This must be a VERY common request. I have looked through the docs but I must be missing it.
