js.hs-analytics.net, measured loading at ~834ms. On a first visit the cookie
does not exist yet, so a single read returns nothing and the visitor gets no
external ID at all — and a first visit is exactly what an ad click is. So
poll briefly until HubSpot sets it. The SDK loads lazily (~4.5s) and replays
a queue, so an init queued a second or two in still lands before any events

3. Conversion id
sha256(lowercase(email) + "|" + formId + "|" + ISO-hour), first 20 hex,
"lead_" prefix.
- email lowercased/trimmed so casing does not fork the id
- formId keeps two different forms in the same hour from colliding
- the hour bucket is only the server's fallback; the id computed here is
sent to the relay verbatim, so the two paths cannot disagree even when
a submit straddles an hour boundary
Ads Manager's own sample omits event_id. We send it so the pixel event and
the relay event collapse into one conversion instead of counting twice.

How Kisah increased NPS and repeat orders with ClickPost's post- purchase intelligence
Multi-carrier management, AI NDR agents help manage growing demand, especially during festive season.
100% to 0%
Time spent on manual post-purchase operations
20%+
Re order rate
"Earlier, a failed delivery meant days of manually calling customers, and by then the order was already marked RTO. With Parth, we reach the customer within hours across multiple touchpoints, and the feedback goes straight to the courier. We're saving orders we used to lose."
Co-founder, Kisah
Kisah's key challenges with logistics operations

Diwali chaos: the courier went unresponsive, pickups and deliveries slipped
Failed deliveries chased by manually calling customers, often too late to recover the order
Returns handled over email, manually verified, then refunded
Nearly all of the team's time went to manual coordination during peak season
