We use it to send bulk emails like any bulk mailing tool, but where it differs is with the campaign builder.

Campaigns allow marketing teams to orchestrate the entire procedure to allow you to publish, promote, follow registered people, introduce participants to the event, etc. 

The elements of Campaigns allow you to automate a marketing activity from start to finish, not requiring human intervention in the process itself. 

Another amazing element of Marketing Creatio is the email template builder. It is very complete, where you can design the email you want and those sent are supported very well. They are presented correctly on any device.
