Take RSVPs without an events platform.

For a meetup, a webinar or a launch, you need names and emails and a way to reach them again. PortForm collects each RSVP, stores it, and can email the attendee a confirmation on the spot.

Your form

Plain HTML on your site

PortForm

Stored · spam filtered · emailed

Your inbox

Every submission, with Reply-To set

Dashboard

Searchable, exportable to CSV

Integrations

Slack, Sheets, CRM, webhooks

Event platforms are built for ticketing and priced for it. A free meetup just needs a signup form, a stored list, and a confirmation email, not a checkout.

A registration form posts to PortForm. Each RSVP is stored and emailed to you, an autoresponder can send the attendee their confirmation and the details, and the full list exports to CSV for your check-in sheet.

Point this at PortForm and it works.

Replace YOUR_ACCESS_KEY with the access key from your dashboard. Create one free. The endpoint and the honeypot are already wired in.
