I'm using iterables for client's campaign tracking in social media campaigns as well with CRM database via API integrations like Zapier etc - which are super useful! The app allows us (the Marketing Agency) have visibility of our clients' performance through data points collected from all channels they're present within; helping track ROI &gt across different platforms or services provided by their teams/clients such an Eventbrite registration process management toolset up service engagements I love how easy it is to use! It's so easy to set up campaigns and track performance. The analytics are very detailed and customizable. I really like the integration with Slack and Mailchimp. There are some bugs with the reporting side of things, but they are working on them. We have been able to grow our email list by over 1000% in less than 6 months since using iterable. We were missing one of our main channels for growing our list, and iterable has helped us fill that gap.
