Can I keep my HTML form when moving from Formspree?

Yes. Change the action to the coss.com form's endpoint. The _gotcha honeypot works under the same name, and _next sets where the browser goes afterwards.

How does coss.com filter form spam?

Every submission passes the honeypot, then a coss.com Risk assessment of the email, IP, browser, captcha and the text. Spam gets the same answer as a success, so bots learn nothing.

Does coss.com Forms integrate with Slack or Google Sheets?

Not directly. Accepted submissions go to your webhooks, to your team by email and into your coss.com contacts; Formspree has ready-made integrations for those tools.

How long does coss.com keep submissions?

Accepted submissions for 90 days and spam, held and unconfirmed ones for 14 days. Download them as CSV from the dashboard, or forward them to your own store with a webhook.

coss.com vs Formspree

Formspree has more integrations and keeps submissions longer. coss.com Forms screens every submission with Risk and feeds your contacts.

Both give a plain HTML form an endpoint to post to, with no backend, a _gotcha honeypot and email notifications. Formspree connects to Slack, Google Sheets, Zapier and two dozen other tools. coss.com Forms runs every submission through coss.com Risk, sends accepted ones to your webhooks, team and contacts with double opt-in, and renders hosted pages.
