Mailercloud's WordPress plugin connects the forms you already use — Contact Form 7, WPForms, Elementor, Gravity Forms, Ninja Forms, and Formidable — to your Mailercloud account, captures leads automatically, and keeps your contacts in sync. You can also build forms with Mailercloud's own drag-and-drop builder. To install the plugin, follow these simple steps:-
Login to your WordPress account as an administrator.
Go to Plugins > Add New, search for the Mailercloud plugin, and install it.
Activate the Mailercloud plugin under the plugin section.

Once done with installing the Mailercloud's WordPress plugin, you can connect it with your Mailercloud account with these steps:-
Go to your store’s “Admin Panel” in WordPress.
Click on “Mailercloud”, appearing on the bottom of the side menu list.
Enter the Mailercloud API Key. To find your Mailercoud API key login into your Mailercloud account. Go to Account> Integrations > API Integrations. (Or, you can click here)

4. Click “Verify” and keep a track of all your account details such as current plan, total contacts, used contacts, remaining contacts, and more.
