What FormSubmit is

FormSubmit sends HTML form submissions to an email address without requiring PHP, JavaScript or backend code. To connect a form, set its action to a FormSubmit URL, name its fields and confirm the email address after the first submission. It is aimed at designers and developers who need a form backend. Forms can set a Reply-To address and subject, copy other recipients, send an autoresponse or redirect submitters to a custom thank-you page. Users can choose among three email templates. Spam controls include Google reCAPTCHA v2 and v3, optional honeypot fields and submission validation. A form can trigger a webhook for each new submission, and AJAX submissions can work cross-origin without leaving the page. File uploads are allowed up to a combined 10 MB per submission. Submissions remain available for 30 days and can be retrieved through an API limited to five accesses per day; uploaded files are not kept in the archive or available through the API. The cloud service has a free plan with unlimited forms and submissions.
