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.

The problem
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.
How PortForm solves it
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.
A form you can copy
