Frequently Asked Questions

Common questions about Double Opt-in for CF7

No. This plugin works only with Contact Form 7 which is one of the best and flexible plugins.

For the time, yes. Submissions must be stored somehow by the time of confirmation. I'm working on a built-in solution with automatic submission data removing when form expires, but it'll take some time.

No. You can be only certain that this person has access to emails in submitted email address account. This usually means being an account owner and is considered as secure contact confirmation. Just remember that it doesn't really mean that the rest of information submitted with your form has to be true/legal or whatever.

Yes. It's as accessible as the core WordPress admin area. The optional custom file upload input is also built with accessibility in mind. All the options and settings can be easily used with screen readers, and the color contrast meets Web Accessibility Initiative standards. If you find some elements of plugin UI that need improvement, please report them on support forum.

No. At least now, CFDB7 doesn't offer a hook to modify CSV output. There is a solution in their support page, but it requires direct plugin file modification.
