Define your ideal attendee

Decide which industries, company sizes, regions and roles you want in the room, and whether you are targeting buyers, partners, sponsors or speakers.

Build segmented invitation lists

  • Prospects: best-fit accounts and decision-makers.
  • Customers: existing clients for retention and upsell.
  • Sponsors and partners: companies that want access to your audience.
  • Local reach: for in-person events, contacts within travelling distance.

Plan a promotion timeline

For webinars, start promotion two to three weeks ahead with reminders before the day. For conferences and trade shows, start earlier and coordinate with sales outreach.
