Detection strategies
Six strategies, one decision rule and a sensitivity slider.
DiscountHero decides whether a customer is "the same person" as an earlier buyer by combining several signals. You can see and fine-tune every rule on the Settings page.
💡 In short: six detection strategies, each one switchable, each with its own sensitivity sliders. The defaults work for most stores; adjust only when you see false positives or misses in the Activity Log.
What is compared
| Signal | How it is compared |
|---|---|
| Email address | Normalized (lowercase, spaces removed), exact or similar |
| Phone number | Normalized (country code unified), exact |
| First name and last name | Similarity score, tolerant to typos |
| Shipping address (street and house number) | Normalized and compared as text fragments, so "Hauptstr. 5" and "Hauptstraße 5" still match |
| IP address | Exact |
The six strategies
| Strategy | Detects a duplicate when |
|---|---|
| Exact email | The email address is identical |
| Exact phone | The phone number is identical |
| Similar name + similar address | First AND last name similar (default 80 %) AND address similar (default 96 %) |
| Similar address + similar email | Address similar (96 %) AND email similar (90 %) |
| Similar email + exact IP | Email similar (90 %) AND same IP address |
| Exact IP + similar name | Same IP address AND first AND last name similar (80 %) |
Each strategy can be switched on or off individually.
How the strategies are combined
The decision rule sets how many strategies have to agree:
- At least one (default): a single matching strategy is enough.
- Majority: more than half of the active strategies must match.
- All: every active strategy must match. Very strict, few removals.
- None: detection is off, nothing is removed.
Sensitivity sliders
Every "similar" condition has a slider from 0 % to 100 %:
- 100 % means only identical values count.
- Lower values accept bigger differences, for example more typos.
Example: lowering the address slider of "Similar name + similar address" from 96 % to 90 % also catches "Hauptstr. 5" vs. "Haupt Strasse 5". Raising the name slider to 95 % avoids matching "Anna Müller" with "Anne Müller".
Use Reset to default on any strategy to go back to the standard values.
How to tune safely
- Open the Activity Log and look at recent removals and their justifications.
- Too many legitimate customers hit? Raise the sliders of the strategy that fired, or switch to "Majority".
- Obvious duplicates get through? Lower the sliders slightly or make sure "At least one" is selected.
- Change one thing at a time and check the log again after a few days.
Changes are saved with the save bar at the top of the page. See Activity Log and your numbers.
