We use Sendgrid and are having issues with our setup of the Unsubscribe feature in our emails.
We want to allow recipients to unsubscribe to marketing emails but NOT allow them to unsubscribe from transactional emails (like order confirmation/receipts).
Would like someone to set this up... Ideally perhaps we'd have an Unsubscribe link in our email, user clicks it and it goes to a website where users can see that we have several email groups (e.g. News, Marketing) and they can select which ones they want to opt-out of. Again, even if they try to globally opt out of emails, we don't want that to mean they won't receive transactional emails.
The way the project will work is you will speak to our marketing person who will explain what our requirements in greater detail and then you go implement it.
