Settings

Contact Form → Settings holds what applies to every form. A form can still change its own messages, skip the captchas or stop saving entries in its editor.

Tab	What it holds
Spam	The honeypot, the least time to fill a form, messages per visitor, the Disallowed Comment Keys, Akismet, and the keys of Cloudflare Turnstile, hCaptcha and Google reCAPTCHA v3. A captcha with both keys runs on every form.
Messages	The texts visitors read after sending, or when a field needs fixing. Leave one empty to keep the text Re:Maily comes with.
Entries	How many days to keep entries (0 keeps them until you delete them), how much of the visitor’s IP address and browser to save, and whether deleting the plugin removes its forms, entries and settings.
Payments	The keys of Stripe and PayPal, and whether PayPal runs live or in its sandbox. The Stripe and PayPal fields need them.
Integrations	The Brevo API key. Each form then picks its Brevo lists in its Advanced tab. See Brevo.
Export & import	Download your forms as a file, or bring in a file made on another site. Entries stay where they are.
Migrate from CF7	Shows only while the site has Contact Form 7 forms. See From Contact Form 7.
