Newsletters, sponsorships and ads often land in "Direct" because email clients and apps strip the referrer. UTM parameters fix that.
How to set it up
- Add
utm_source,utm_mediumandutm_campaignto every link you share outside your site, e.g.?utm_source=newsletter&utm_medium=email&utm_campaign=october. - Open Source → Campaign in your dashboard: each value appears with its visitors and revenue.
- Use
utm_medium=emailfor newsletters andcpcfor paid search so they're grouped in the right channel.
