Formspree runs your form. Doorman reads it.
Formspree is a solid, complete form backend: storage, email, integrations and a form builder. If spam is the problem, Doorman is the specialist: it reads every message, explains each call, and costs far less per submission.
Free for 1,000 checks a month. Paid plans from $12. No card required.
Example: Doorman screening contact form, each judged in under half a second and delivered or kept out with the reason.
Sound familiar?
Priced by submission
The free plan is 50 submissions a month, and spam uses them up too.
Advanced filtering costs more
The tunable spam filter starts on the $20 Professional plan.
No reason per submission
The docs describe sensitivity levels, not why a given message was filtered.

Which one is right for you?
Choose Doorman if
- Spam is the problem you're trying to solve
- You get more than a few hundred submissions a month
- You want the reason for every decision and unsure ones held
- You want sign-ups and checkouts screened as well
Choose Formspree if
- You need file uploads, a form builder or submission storage with integrations
- You don't have a backend and spam is a minor issue
- Your form gets very few submissions
Switch in two minutes
- Change one URL: set the form's action to your Doorman URL; field names are detected.
- Where real ones go: email, Slack or a signed webhook, retried if your endpoint is down; everything is also in your inbox.
- Or ask your agent: copy one prompt into Claude Code, Codex or Cursor and it does the swap.
- Start safely: watch mode delivers everything for a week and tags what it would have dropped.

Checked, not guessed
Every decision comes from Doorman's models reading the submission, in milliseconds, with the reason attached.
Labelled test set: 104 invented but labelled contact-form and checkout submissions, judged live; latency is the median of those checks. Questions were not tuned to the set.
Questions
Does Doorman store submissions?
Yes, in your inbox for your plan's retention period (30, 180 or 365 days), and it forwards the real ones to email, Slack or a webhook.
Can I keep Formspree?
If your server posts to Formspree, call Doorman first and only send what it delivers. For a plain HTML form, point it at Doorman instead.
Does it handle file uploads?
No. Doorman reads the text fields; file uploads are ignored.
How much does it cost?
Free for 1,000 checks a month. Pro is $12 a month for 25,000 and Business is $49 a month for 250,000. Every plan gets the same models. See pricing.
