Contact Form 7 to Mailjet is a plugin developed by Youdemus.
This plugin allows you to automatically fill in a contact list on Mailjet, or database, each time a user submits a contact form on your WordPress website with Contact Form 7.
The huge benefit of this plugin is that it allows you to create a specific email’s database on Mailjet to distinguish contacts from your site. You can also specify a specific list for each of your forms.
This plugin requires that the official Mailjet plugin is properly configured (API). This is not an official Contact Form 7 plugin or Mailjet plugin.
It is also possible to associate a check box for the GPRD if you have one in your contact form.
For help in installation, please check FAQ or contact us directly.

Just remember that the first field must be the email shortcode from CF7. By default, it's "your-email".
