Technical warning about re-using mail API key.
_This issue/bad practice relates to integrations using automatic webhook management, such as Mailgun, Mailjet, Sendinblue, and UniOne if you don't choose the manual setup option._
Bloomreach Engagement allows you to use the same mail API key in different integrations even in different projects. However, this practice is not recommended, because all integrations with the same API key will share just one mail provider webhook for tracking delivered campaign events.
Deleting any of these integrations with a shared API key will result in deletion of the webhook and therefore none of the given projects will have tracking of delivered campaign events.
