Add your own UTM parameters to your referral link:
`https://senly.nl/?ref=YOURCODE&utm_source=linkedin&utm_campaign=spring2026`
Common parameters:
- `utm_source` — the channel (linkedin, newsletter, youtube)
- `utm_medium` — type (social, email, video)
- `utm_campaign` — name of your action (spring2026, demo-video)
Senly saves `utm_source` and `utm_campaign` with each conversion. On your affiliate dashboard you see per source and campaign how many signups + earnings — useful for seeing which channel performs best.
