What link tracking is for
Sales teams send links constantly: a quotation PDF, a catalogue, a site plan, a payment page, a booking form. Once the message leaves, the trail usually goes cold. Link tracking replaces each ordinary link with a version tied to that customer and that send, so when it is opened, the click appears on their record in the CRM.
The payoff is timing and specificity. Instead of a follow-up on day three because that is the rule, the call happens on the afternoon the price list was opened, and it starts with the right subject. That is a small change in behaviour with a disproportionate effect on conversion, because most deals are lost to silence rather than to objections.
