Sending a e-mail through Web Designer on a button click

Good Morning,

I am working on Version 8.0.

I have a custom form for on-boarding a user in the Web portal. During the on-boarding process the form checks if a person with the same First and Last Name already exists in the system and brings up a pop up which mentions the same. The client wants to add a functionality such that on the click of a button on that popup a e-mail will get sent to a certain business role notifying them of the user that already exists.

Taking a look at the option on that button i can do things like 'save changes to person, close popup' etc. 

Is sending out an e-mail something which is possible on the click of a button from the Web Portal? 

Any suggestions or feedback would be appreciated.

Thanks

Mohit Singh
