TL;DR
- What it is: Finding webinar attendees’ emails means enriching your event registration list — which is often full of personal addresses like @gmail or @yahoo — into verified business emails and direct-dial numbers.
- How to do it: Export your webinar platform’s attendee report (Zoom, Goldcast, ON24), isolate First Name, Last Name, and Company into a clean CSV, then upload it to the Lusha Bulk Enrichment tool mapping the Name and Company fields to get verified corporate emails and mobile numbers.
- Why speed matters: The gap between a 2% and 20% conversion rate on webinar leads comes down to data completeness and speed — enriching and assigning leads the moment the webinar ends (not the next day) keeps reps dialing while the prospect still remembers the content.
- Beyond the attendee: Segment enriched contacts by engagement (minutes viewed, questions asked) into tiers, route high-engagement Tier A leads to senior AEs for immediate calls, and for those accounts also find the attendee’s Director or VP to multi-thread the deal.
A webinar registration list is one of the highest-intent data sets in sales, yet most teams let it sit in a CSV file for days until the lead is cold.
If your post-event strategy is limited to a generic “thanks for joining” email, you aren’t just missing opportunities. You’re ignoring them.
That’s why winning the webinar game requires moving from passive follow-up to high-velocity enrichment. To turn viewers into meetings, you need to bridge the gap between a registration form and a verified direct dial.
Here is the step-by-step guide for finding attendee emails and converting event interest into predictable pipeline.
1. Export and isolate the company anchor
Most webinar platforms (Zoom, Goldcast, ON24) provide an attendee report, but it’s often plagued by personal email addresses (@gmail, @yahoo) and junk titles.
- What to do: Export your report and create a clean CSV with three columns: First Name, Last Name, and Company.
- Pro tip: Even if they signed up with a personal email, the “Company Name” is your anchor. Do not discard these leads. The company name allows you to cross-reference the lead against professional databases to find their actual business contact information.
2. Bulk enrich to bypass the personal inbox
You cannot run a professional outbound sequence to a @me.com address. You need to map these registrants to their corporate identity.
- What to do: Upload your cleaned CSV to the Lusha Bulk Enrichment tool. Map the Name and Company fields.
Lusha will scan its database to find the verified business email and direct-dial mobile number associated with that person at that specific company. Within minutes, your list of 500 names becomes a list of 500 validated corporate prospects.
3. Segment by time on site and engagement
Treating a person who watched two minutes of a webinar the same as someone who stayed for 55 minutes is a waste of resources.
- What to do: Sort your enriched list by minutes viewed.
- The tiering:
- Tier A: Stayed 45+ mins and asked a question.
- Tier B: Stayed 30+ mins but remained silent.
- Tier C: Registered but never logged in.
Assign Tier A to your senior AEs for immediate phone calls, and put Tiers B and C into automated, persona-specific email sequences.
4. Reach the right stakeholder
Often, the person attending the webinar is not the one with the budget. Use their attendance as a trigger to reach out to their boss.
- What to do: For your Tier A accounts, use Lusha to find the Director or VP in the same department as the attendee.
Send a LinkedIn message to the VP: “Your team was just on our session about [Topic]. I noticed a few questions came up regarding [Pain Point]—I’ve put together a 2-page summary of the solutions we discussed for you to review.” This turns a single viewer into an enterprise-wide conversation.
5. Automate the handoff with CRM plays
Speed-to-lead is the only metric that matters after an event. If you wait until the next day to enrich and assign leads, you’ve already lost the window of relevance.
- What to do: Set up a workflow that connects your webinar platform directly to your CRM.
Configure the play so that the moment a webinar ends, every attendee is automatically enriched with a business email and direct dial, then synced to a webinar hot leads campaign in Salesforce or HubSpot. This ensures your reps are dialing while the prospect is still thinking about your content.
Using attendee lists to drive pipeline
The difference between a 2% and a 20% conversion rate on webinar leads is data completeness and speed.
By automating the enrichment process and multi-threading the account, you stop being a “thank you” note and start being a strategic partner.
