FormBackend is an easy way to hook up your static HTML form, with an endpoint that captures form submissions. Send an email to the submitter, receive an email when new submissions come in. Send submissions to third parties such as Slack, Trello, Google Sheets etc.
It does the basics well, and the founder is very responsive to customer support requests and suggestions.Cons:
A bit pricier than I would like, but still reasonable.
I've tested over ten form endpoint solutions and FormBackend was the one that covered the features we needed and had the most reasonable price.Miriam Schwab has used this product for one month.
