What FormSubmit is
FormSubmit is a cloud service that 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. The service is aimed at designers and developers. Email controls include setting a Reply-To address, subject, CC recipients, autoresponse, and redirect to a custom thank-you page; users can choose among three email templates. Spam controls include Google reCAPTCHA v2 and v3, honeypot fields, and submission validation. A form can trigger a webhook for each new submission, and AJAX submissions can work across origins without leaving the page. Forms accept file uploads up to a combined 10 MB per submission. Submissions remain available for 30 days and can be retrieved through the API, which allows five accesses per day. Uploaded files are not kept in the archive and are unavailable through the API. The free plan costs nothing and includes unlimited forms and submissions.
