As I said on the title, we are sending to our customers invoice mails with a HTML body and and attached PDF with the invoice itself. I cannot put examples because they have confidential information.
Surprisingly some of them are generating an event of an hotel reservation on the customer gmail at google calendar. The 'reservation' code are the same as the invoice code and the name of the hotel are very similar to the address of my office, it seems like google are parsing our mails and creating automatically an event.
I know the mail markups of google https://developers.google.com/gmail/markup but I'm not using it, evenmore, what I want is to avoid this behavior for all of our mails, but the google documentations only has information about how to add this behavior, not how to avoid it.
anyone know how to avoid at all the automatically event creation in the emails by gmail? What I want is just know if there are some markup or similar for the emails to prevent it. Any solution on the customer side is not possible in our situation.
Thank you all.
