Heureka „Ověřeno zákazníky“: review-request pipeline with no manual touch

Heureka dominates Czech price comparison — without the „Ověřeno zákazníky“ badge you lose conversions and search visibility. The Heureka API lets the „Ověřeno“ programme send a review link to the buyer after delivery. 4notify wraps that link in a branded email template, schedules it D+7 from delivery confirmation and syncs the resulting review back into the CRM via signed webhook.

Problem

Most e-shops either send the Heureka link from a generic no-reply (looks like spam, only 8% click) or send too late (after two weeks when the customer no longer uses the product). Heureka's official email gets 16% open rate; your branded version hits 42%.

Legal framework

Heureka Obchodní podmínky služby Ověřeno zákazníky

Forbid modifying the link but allow you to wrap it in any template. 4notify builds the template, the link itself comes from Heureka.

Zákon č. 89/2012 Sb. § 1820 (informační povinnost)

A review request is a service email tied to a closed contract, not marketing — no opt-in needed, but opt-out must work.

GDPR čl. 6 odst. 1 písm. f (oprávněný zájem)

Review collection is a legitimate interest of the controller; a balancing test is required and 4notify provides a DPIA template.

Architecture

Trigger on DELIVERED status

When Zásilkovna / PPL / Czech Post confirms delivery, dispatch is scheduled for D+7. If the customer returns in between, the pipeline is cancelled.

Branded template

Email looks like it's from your e-shop (logo, colours, manager's signature). The Heureka link is just one element; the order summary is included.

Review sync back into the CRM

Heureka publishes a review webhook; 4notify HMAC-signs it, enriches with the customer and pushes to your CRM (Salesforce, HubSpot, Raynet, custom).

Negative-review reaction

If the customer leaves ≤ 3 stars, the customer team gets an internal notification with order summary and a chance to react proactively instead of sending another follow-up.

Only pipeline that automatically cancels the review request on return and escalates negative reviews to support before they go public.

FAQ

Can we send the review request via SMS?

The Heureka link technically goes through, but CTR is dramatically lower (4%) than email (38%) — users in mobile switch context faster. We recommend SMS only as a follow-up nudge.

What about orders from other platforms (Mall, Allegro)?

4notify supports parallel review pipelines for Mall „Ověřeno Mallem“, Glami and Zboží.cz. Unified dashboard with cross-comparator reputation.

How does Heureka know the item was delivered?

Heureka relies on your report; 4notify fetches the carrier status and forwards it via API. Without 4notify, manual entry would cost hours per week.
