Event Planning lead verification
Event planners manage contact lists that span vendors, venues, sponsors, and attendees simultaneously — four completely different audiences with different data sources and decay rates. Vendor contacts rotate as account managers change; attendee emails are often event-specific aliases that expire after the conference ends. A single unverified blast to a mixed list can trigger spam complaints from people who never consented to ongoing marketing.
What's hiding in your list
Venue and vendor contacts gathered at trade shows age rapidly as staff turn over, leaving planners with lists full of departed account managers.
Attendee registration platforms often allow bulk imports from corporate directories, where shared departmental emails (like events@company.com) suppress meaningful engagement metrics.
Multi-day event sign-in lists merge digital and paper registrations, creating duplicate records with slight name or email variations that inflate head counts.

Frequently asked
We re-use our vendor database across multiple events each year. How often should we validate it?
Industry contact data turns over at a meaningful rate in hospitality and events, so validating before each major campaign cycle is practical. BounceBlock can process your full vendor list in minutes, and the flat monthly pricing means there is no per-record cost penalty for running it regularly.
We collect phone numbers for day-of logistics. Are those worth validating too?
Absolutely — a disconnected number for a key vendor contact discovered on event morning is a genuine operational risk. Running phone validation in advance confirms whether a number is active and whether it is a mobile or landline, which matters when you need to reach someone urgently via SMS.
Our sponsor contacts are companies rather than individuals. Can we verify those too?
Yes — BounceBlock includes company data enrichment alongside email and phone validation, so you can confirm a sponsoring organisation still exists at the domain and address you have on file, which is particularly useful when account managers change between annual events.
