FAQ

These are short answers to the questions people ask most about FormThunder: whether the access key is safe in public HTML, what happens when you pass your limit, how long submissions are kept, and how FormThunder relates to Web3Forms. For fixing something that's broken right now, see troubleshooting.

Is the access key safe in my HTML?

Yes. It's public by design and can only send to addresses you've verified. Someone who copies it can post to your form, which is the same as filling it in. Domain restriction on Pro limits where posts can come from. API keys starting with ft_live_ are different: they're secret.

What happens when I go over my monthly limit?

Submissions are stored and held. They're released and delivered when the account upgrades. You get an email at 80% of the limit and again when you reach it.

How long are submissions kept?

The dashboard keeps 30 days of history on Free, and 1 year on Pro and Agency. You can export to CSV on every plan.

Do I need AI to use FormThunder?

No. A plain HTML form works without any AI, and so do the dashboard and the API. MCP and the CLI are there if you want an agent to do the setup.

Which AI tools work with it?

Anything that speaks MCP, such as Claude Code or Cursor, or anything that can run a command line, using npx formthunder.

Is FormThunder the same as Web3Forms?

No. It's a separate product that accepts the same form fields, so a form can move across by changing its action URL and key.

Can a form have several recipients?

Yes: 1 on Free, 5 on Pro and 10 on Agency. Each recipient must be a verified linked email.

Can I use my own sending domain?

Not today. Emails come from FormThunder's sending address, with your chosen from name and reply-to.

Do I need JavaScript?

No. A plain form post works, and our helper script is optional. It's only needed for captcha widgets and the advanced uploader.
