Sending email to one person based on choice if radio button

Hi! so i have a question, I’m trying to send an email to a single person based on the choice the user made on the radio button group(this would be in 6 different pages as there’s six different users that will have a personalized page and question to answer) and also based on the choice they would be taken to a different page. This would happen after the user chooses the answer and hits send. Is SendGrid the only option for this type of task?

Thank you!

If it is an email that the user fills in themselves and sends on, then you can simply set the value of the radio button to a specific vale which could be the persons name.

Then in your code simply write that if that name is selected in the radio button choice, then you can use the Wix Location to() function to open an email window for the user to write in.

If it an email that you want to be sent, then you have different options.

The Sendgrid examples as you have already mentioned.
