Revisend for Contact Form 7

Contact Form 7 is the most popular form plugin on WordPress, but it sends the
mail the moment the visitor clicks the submit button. Revisend for Contact Form 7
adds an optional confirmation step: after the form passes Contact Form 7’s
native validation, the visitor sees a summary of what they typed and must
click “Confirm & Send” before the form is actually submitted. If they spot a
mistake, they can go back with “Edit”.

Why use it?

• Reduce mistakes — visitors can review their input before it is sent.
• Native CF7 validation — required-field and format messages are shown
  exactly as Contact Form 7 normally shows them, before the review step.
• Per-form toggle — enable the review step only on the forms you want.
• One-time token — prevents double submissions and bypass attempts.
• File uploads supported — files are preserved between the review step
  and the confirmed submit, then attached to the mail.
• Built-in spam protection — honeypot field and minimum-fill-time check.
• Lightweight — no jQuery, no external services, translation-ready.
