Sound familiar?

Add Doorman as your Webflow form's webhook. Every submission is read in milliseconds: real enquiries reach your inbox or Slack, and pitches, SEO outreach and bots stay out, without you ever having to look.

No code: you add one webhook URL to your Webflow form's settings. 14 days of Pro free, no card. Then free for 100 submissions a month, or Pro from $29.

  1. Webflow's spam filter lets pitches throughAgency and SEO outreach is typed by people, so it passes any bot check and lands in your notifications looking like a lead.
  2. reCAPTCHA adds friction and still missesA challenge on your contact form costs real enquiries, and a person paid to paste pitches solves it anyway.
  3. Every client site gets the same junkIf you build on Webflow for clients, each one forwards you the spam and asks you to fix it.

Set up in Webflow in two minutes

  1. In the Designer select the Form Block, and in its settings add a Send to destination: Webhook, with your Doorman form URL.
  2. Then remove Webflow's email so pitches stop reaching your inbox. Doorman emails you the real ones; your form and its success message stay as they are.
  3. Field names keep Webflow's own (Name, Email, Message); they're detected.
  4. Where real ones go email, Slack or a signed webhook, retried if your endpoint is down.
  5. Start safely watch mode delivers what it would have dropped, tagged, until you switch it to enforce.

Questions

Does it replace Webflow's form handling?

No. Doorman is added as a webhook destination, so your form works exactly as before. Remove Webflow's own email destination so pitches stop reaching you; Doorman keeps every submission in its inbox and forwards only the real ones. (Prefer to hand the form over entirely? Use a Custom action instead, which is what the Doorman app for Webflow sets up: Webflow then stops storing and emailing that form's submissions, and visitors see Doorman's thank-you page or one you choose.)

Do I need a paid Webflow plan?

Form destinations are set in the Designer; on a custom domain, Webflow needs an active site plan for forms. No Webflow app or code embed is needed.

Will my visitors see anything different?

With the webhook setup above: no captcha, no new script and the same success message, whatever the verdict. A pitch never learns it was screened out.

How much does it cost?

Free for 100 submissions a month. Pro is $29 a month for 5,000 and Business is $79 a month for 50,000, and every account starts with 14 days of Pro. Until November 30, the first 100 paying customers get Pro at $19 and Business at $59, kept for as long as they stay. See pricing.
