Does Form Plume require rebuilding the frontend form?

No—Form Plume works with forms you already built by changing the form action to the provided endpoint.

How does Form Plume handle spam submissions?

Every submission is filtered for spam, and suspected spam is sent to a recoverable quarantine rather than disappearing.

Can Form Plume deliver submissions to places other than email?

Yes. Submissions can be sent to destinations like a searchable dashboard and tools such as Slack, Discord, Sheets, and marketing platforms.

What are signed webhooks used for?

Signed webhooks send submission events to an external endpoint, and your server can verify the signature before processing.

Product Overview

Form Plume is a form backend for HTML and JavaScript contact forms that need a destination for submissions. Instead of building and maintaining a separate backend, it lets developers point an existing form’s action to a single Form Plume endpoint.

Submissions are captured, filtered for spam, delivered to email and other destinations, and recorded in a searchable dashboard. It also supports file uploads, email notifications, autoresponders, routing, exports, integrations, and signed webhooks that a server can verify—while keeping full control of the frontend.

Key features

Point any HTML/JS form to one Form Plume endpoint by setting the form action URL.
Spam filtering routes suspected spam to a recoverable quarantine instead of dropping it.
Deliver submissions to multiple destinations such as email and team/tools like Slack, Discord, and Sheets, plus marketing tools like ActiveCampaign and Mailchimp.
Support file uploads using the same endpoint you set on the form.
Provide signed webhooks your server can verify, along with dashboard access and CSV exports.

How Form Plume works

1
Set form action endpoint
Update the form’s action attribute to post to a Form Plume endpoint.
2
Submit and verify delivery
Send a test submission and confirm it lands in the inbox and the Form Plume dashboard.
3
Route destinations and webhooks
Configure where submissions go (email/tools) and use signed webhooks for events your server can verify.

Use cases

A developer adding lead capture to an existing static site: they keep the current frontend components and only change the form action to send real submissions to email and a dashboard.
An agency managing multiple client forms: they capture once with one endpoint and route submissions to Slack/Discord and spreadsheets/CRM tools for team visibility.
An indie maker handling contact requests with attachments: they enable file uploads and use webhooks to trigger server-side workflows while keeping spam quarantined for review.

Who is it for?

Form Plume is built for developers, agencies, indie makers, and small teams who want reliable lead capture without building a custom form backend. It fits projects that need email notifications, spam protection, and routed submissions across common tools.
