You're sitting in a conference hotel room at 6 AM, coffee in hand, scrolling through the attendee list. You know 200 people are going to be in that keynote today - potential clients, decision-makers, people who actually need what you sell. But here's the problem: talking to them at the event itself is a gamble. The booth is crowded. Conversations are surface-level. You get business cards but rarely anything actionable.
What if you reached them before they even got on the plane?
A cold email industry event campaign isn't about pitching at the event. It's about starting conversations 2-4 weeks before, so when they show up, you're already in their head. You're not competing for attention at a crowded booth - you're the person who already said something relevant to them.
Here's how to actually do it.
Step 1: Build Your List 4-6 Weeks Out
Don't wait until the event to get the attendee list. Start sourcing names now. Here's what works:
- LinkedIn event page: Most conferences post attendees on their LinkedIn event. Run a search for people attending, filtered by company size, role, and industry. You can manually pull 50-100 names this way, or use a LinkedIn scraper like Hunter.io or Clearbit to speed it up.
- Company websites: If you know which competitors or adjacent companies will be there, pull decision-makers from their websites. Use a tool like RocketReach or Apollo to find email addresses.
- Previous attendee data: If this is a recurring event, check past attendee lists online. Same companies often send similar people year after year.
Target 200-400 people. Not everyone will be a fit, but you want volume so you can be selective.
Once you have names and emails, score them. Prioritize people who:
- Work at companies with 20+ employees (usually means budget and actual decision-making authority)
- Have titles suggesting they buy what you sell (VP of Sales, Director of Marketing, etc.)
- Work in industries where you've had success before
Step 2: Write an Email That References the Event Specifically
This is where most people mess up. They send a generic cold email and mention the event as an afterthought. That doesn't work.
Your opening needs to show you know they're going to the event and why it matters to them specifically. This takes 10 seconds of research per person, but it changes everything.
Here's the structure:
Hi [Name],Saw you're heading to [Event Name] next month - figured this might be worth a quick conversation beforehand.We've helped [specific company type] at [specific companies, if you can mention them] cut their [specific metric: sales cycles, implementation time, etc.] by [specific number: 3 weeks, 40%, etc.] using [one-sentence description of what you do].Most people at [Event Name] are dealing with [specific problem relevant to the event theme] - curious if that's on your radar?Thought it might be worth a 15-minute call this week to see if it's worth a longer conversation at [Event Name].[Your name]
Notice what's happening here:
- You mention the event by name - they immediately know you did your homework
- You reference their specific industry or company type - not generic
- You give a concrete result, not vague benefits
- You frame it as a pre-event conversation, not a sales pitch
The goal isn't to close a deal. It's to have a 15-minute call before the event so you can actually meet with them there with context.
Step 3: Send in the Right Window
Timing matters. Send too early and they forget about the event. Send too late and they've already made their plans.
Send your first email 18-21 days before the event. That gives them enough time to think about it without being so far out that it's forgotten.
If you don't get a response, send a follow-up 10-12 days out. Keep it short:
Hey [Name],Quick bump on the previous note - still interested in chatting before [Event Name]?I know it's a busy time. If not, no worries - would love to connect at the event itself.[Your name]
If they respond positively, book the call for 7-10 days before the event. You want enough time for them to actually think about what you discussed before they get there.
Step 4: Segment Your Follow-Up by Response Type
Not everyone will respond. That's normal. But your follow-up at the event needs to be different depending on whether they engaged or not.
People who called: Send them a pre-event note thanking them for the call, reminding them of one specific thing you discussed, and confirming you're both going to be there. Ask them to text or DM when they arrive and grab coffee.
People who responded but didn't call: Send them a pre-event email that's more conversational. Reference something specific about their company or role. Ask if they want to grab a drink at the event instead.
People who never responded: Don't ignore them. But don't be salesy either. Send a note a few days before saying something like:
