Is it possible to set different content in a letter depending on the client?

Question

Email Marketing

Is it possible to set different content in a letter depending on where the message will be opened - in the mail client or in the web version?
Specifically, the sender wants to embed an inline svg with a little animation in the body of the letter, but in almost all email clients this svg will not be displayed.
So is it possible that in the client, if svg is not opened, would a regular picture be loaded?

Answer 1

Something tells me that in html there is an alt option for pictures, and it is not necessarily text.
