Frequently asked questions

How do I make this inline (email + button on one line)?

Use display: flex on the field row in the Plain CSS version, or flex sm:flex-row in the Tailwind version.

Does this work with Mailchimp / ConvertKit / Beehiiv?

Yes — replace action with your provider's form endpoint. Or pipe through LemForms and connect every provider with one webhook.
