The fair ends Sunday evening; the conversion window opens Monday morning and closes by the second weekend. Inside that window the cadence is fixed by visitor memory and competitor speed: a personalised touch in 24-48 hours, a content touch on day seven, a closing meeting ask on day fourteen. Every day of delay halves the reply rate. This section covers the cadence that experienced European exhibitors run, the handoff mechanics that move qualified leads from marketing to sales without friction, and the conversion benchmarks that match B2B sales cycles of 6-14 months.

Lead conversion at European trade fairs lives or dies in the 48 hours after closing day. A day-by-day follow-up cadence with EUR conversion benchmarks, channel mix, and named-platform automation guidance.

A five-touch post-show email sequence with subject-line patterns, body templates, send-day cadence, and performance benchmarks across European tier-one fairs. Includes score-band routing and the breakup-sequence discipline that closes the loop.

Trade fair lead value decays roughly 20 percent per day after the conversation. The 72-hour rule, the operational playbook to execute it, and the SLA discipline that separates exhibitors who recover EUR 1M in pipeline from those who lose it.
