How do I make a signup sheet without making people create an account?
Use a signup tool that lets people respond with just their name and an optional email, no account or password. Requiring accounts is the most common reason a signup sheet underperforms.
Likely causes and how to fix them
Your current tool gates responses behind a login
Switch to one where responding needs no account. With Grasshopper, neither the organizer nor the respondents are required to sign in to participate.
You still want to reach people afterward
Collect an email as an optional field. You get a way to follow up without forcing account creation.
People sign up with a name and an optional email. No account, ever. Make a no-login signup sheet
