MailCannon WordPress Plugin

MailCannon – Email Marketing & Campaign Sender connects your WordPress site to the MailCannon SaaS platform so you can send MailCannon campaigns to your WordPress users or WooCommerce customers directly from the WordPress admin.

Contacts are not managed in WordPress. Contacts are managed in the MailCannon dashboard:
https://mailcannon.pro/dashboard/contacts

When you send a campaign from WordPress, MailCannon will automatically create the contact in your MailCannon account if it does not already exist.
