Send data(table) to outlook?

Question

ASP.NET

Good afternoon, there is an application in which there is a form. We fill it with data and want to send a letter to some users. What we want to implement: so that a person opens a letter in outlook (!) And there is a table in the body with the data that we sent. It is impossible to transfer html table through mailto, what are the ways of such a solution? How to automate, so that every time you do not manually create a table there and enter data. Thanks
