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.
