I'm looking for a serverless (online) email form builder.

The content of email has been pre-set. The user just, after filling in name and a valid return email-address and clicking --> [Send], the email will be sent to me automatically.

I has been searching a while and there are many suggestions, such as;
Serverless Form Builder
Create Forms Using a Drag&Drop Interface and Track Conversions
https://www.webiny.com/serverless-app/form-builder/

Top Form Builder Software
https://www.getapp.com/p/sem/form-bu...RoCSTwQAvD_BwE

Alternative products to Form Builder by Webiny
https://www.producthunt.com/alternat...lder-by-webiny
etc.

Please set me some light which of them shall I select or there are some other suggestions. Thank in advance.

Regards
