Why Event Teams Switch to Mailsfinder

Most prospecting tools charge a premium for stale data and make you pay extra for verification. Event marketing teams running speaker sourcing, sponsor outreach, and 5,000-row invitation pushes feel that pain first.

1

Verification ships with every lookup

Every email is verified via real-time SMTP handshake at the point of lookup. No second tool, no extra cost, no risk of torching the inbox you spent six months warming.

2

300,000 credits for $9.99 a month

That brings your cost per verified contact down to $0.001. Hunter charges around $0.025 per email. For a single annual conference, that is the difference between a clean invite list and a maxed-out tool budget.

3

100 free credits every day, forever

Need to find five keynote speakers this afternoon? Start right now without entering a credit card. Use 100 credits daily to find and verify emails at no cost.

4

Built for high-volume bursts

Event marketing is bursty by nature. You need 8,000 lookups the week before a roadshow, then almost nothing for two months. Mailsfinder pricing absorbs that pattern instead of punishing it.

Frequently Asked Questions

How does Mailsfinder help event marketers find speaker emails? expand_more

Event marketers can enter a speaker's name and the company or association they belong to, and Mailsfinder returns a verified email in under a second. For larger speaker recruitment campaigns, you can upload a CSV of target speakers and get the full list back, verified and ready to outreach. Every email goes through real-time SMTP verification, so invitations land in inboxes instead of bouncing.

Can I build sponsor outreach lists in bulk? expand_more

Yes. Upload a CSV of target sponsor companies with the contact name (head of marketing, sponsorship director, brand partnerships lead), and Mailsfinder will process thousands of rows in parallel. Each result comes back verified, so sponsorship sales teams can move from list-building to outreach in minutes instead of days.

How accurate are the emails for event marketing outreach? expand_more

Mailsfinder delivers 99% verified email accuracy through a multi-step SMTP verification process. Every email is checked in real time before it reaches you, keeping bounce rates under 1%. That protects your sender reputation during high-volume invite, sponsor, and post-event follow-up campaigns when deliverability matters most.

How many emails can I find per month for event campaigns? expand_more

The Monthly plan includes 300,000 credits for $9.99/month. The Annual plan gives you 300,000 credits per cycle for $7.99/month billed at $95.88/year, bringing the cost down to $0.001 per verified email. The Lifetime plan unlocks 2,000,000 credits for a one-time $249. You also get 100 free credits every day with no credit card required.

Can Mailsfinder integrate with my event marketing stack? expand_more

Mailsfinder integrates with Zapier, n8n, Make.com, and Google Sheets, which means you can push verified contacts into HubSpot, Salesforce, Marketo, or any event registration platform. The REST API is available on all paid plans for custom integrations with your invitation, ticketing, or post-event nurture workflows.

Is Mailsfinder useful for post-event follow-up? expand_more

Yes. After an event, marketing teams often have a list of names from badge scans, session attendance, or business cards but no verified emails. Upload the list and Mailsfinder returns verified addresses you can use for thank-you sends, content recaps, demo bookings, and pipeline handoff to sales.
