Collect subscribers before you pick an email tool.
You don’t need to commit to a mailing platform to start collecting addresses. PortForm captures each subscriber, stores it, and can push it straight to a Google Sheet or your own tool while you decide.

Signing up for an email platform on day one means paying per subscriber before you have any, and wiring its embed into your site. You just want to catch the addresses first.
A simple email field posts to PortForm. Every subscriber is stored and can be exported to CSV or synced to Google Sheets and Notion, so importing them into whatever platform you eventually choose is one file.
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.
The features this use case leans on.
