What is the "m" parameter on a campaign Web Copy link?

"m" is Message ID.

Here's an example of a Web Copy link where the "m" is at the end of the URL: https://amalik.activehosted.com/index.php?action=social&c=603&m=851

Note that "c" is the Campaign ID.

Any campaign or automation email counts as a message. Split campaigns are considered two separate messages, but one campaign.
