ReferralHero tracks the traffic source of each subscriber automatically. By default, ReferralHero tracks people coming from Facebook, Twitter, Facebook Messenger, Email, Whatsapp, Telegram, Linkedin, etc.
If you want to track your own channels (for example Facebook Ads or your newsletter), simply use UTM parameters (the only one that is really needed for ReferralHero is utm_source).
Sources are a great way to measure your marketing efforts. For example, let's say you send out a newsletter and want to track conversions. You can create a link like http://mylandingpage.com?utm_source=newsletter to use in your newsletter. ReferralHero will take care of the rest.
You can see an example of the Analytics page when using multiple sources in the image below:
