Measuring with consent
Sparsa measures opens and clicks only for people who agreed to it. Everyone else gets a newsletter with no tracking pixel and plain links.
Counted for every recipient
Sparsa needs these results to deliver your newsletters and to keep your list clean.
- Delivered
- Bounces
- Complaints
- Unsubscribes

In the product
Where recipients decide, and where you see the result

02Campaign report
Delivery results for every recipient; opens and clicks only for those who agreed, with opens marked as estimates.
How measurement works
- 01
Without consent, nothing is measured
No pixel and no redirect: links go straight to their targets. That recipient appears only in delivered, bounces, complaints and unsubscribes.
- 02
Opens are estimates
Some e-mail programs load images automatically, so a message can count as opened without being read; others block images and hide real opens. Treat the open rate as a trend, not a fact.
- 03
Withdrawing takes one click
Anyone can stop measurement on the preference page. Unsubscribing from every topic stops it too, and the stored measurements are deleted at once.
- 04
Your organisation decides as well
Each customer can switch measurement off completely. Then the box is not shown and nothing is measured.
- 05
What is never kept
IP addresses and raw browser details of opens and clicks are never stored. Measurements per person are kept for 13 months; after that only campaign totals remain.

It sets no cookies, stores nothing on your device and does not identify you; we see only totals such as page views, referring sites, countries and device types. Nothing else loads from other sites: no other analytics, scripts or fonts. If you switch the theme, your browser remembers the choice on your device; it is never sent to us.
