We have a blood donor database. We currently call all these people to remind them of their appointments. I want to start sending them emails instead.
I thought it would be helpful if the e-mail had a link / image that said "Click here to add to your calendar".
I see at least two concerns with that.
First, I suspect the link data is different based on the type of calendar it may be added to.
Second, I have no idea how to create such a link.
The appointment date / time will be different for each donor.
Suggestions on how to get started on this would be appreciated.
