MailCannon – Email Marketing and Campaign Sender connects your WordPress site to the MailCannon SaaS platform (https://mailcannon.pro) so you can send MailCannon campaigns to your WordPress users and WooCommerce customers from the WordPress admin.

This plugin does NOT manage contacts in WordPress.

You manage contacts 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.

External Services

This plugin relies on the MailCannon external service to list campaigns, test the API connection, and send email campaigns from your WordPress admin.

MailCannon is an email marketing platform used by this plugin to retrieve the campaigns available in your MailCannon account and to trigger campaign sending to the recipients you select in WordPress.

Data sent to MailCannon and when it is sent:

When you save and use your API key, the plugin sends the API key in the X-API-KEY request header whenever you test the connection, refresh campaigns, open the campaigns screen, or open the send campaign screen.
When you test the connection or fetch campaigns, the plugin sends your API key and requests your campaign list from https://mailcannon.pro/api/v1/campaigns.
When you send a campaign, the plugin sends your API key, the selected MailCannon campaign ID, and the selected recipient email addresses to https://mailcannon.pro/api/v1/send-email-campaign-by-id.
Recipient data is sent only when an authorized admin or editor submits the send campaign form from WordPress.

This service is provided by MailCannon:
