What This App Does

This app helps you find email addresses of decision-makers (CEOs, Sales Managers, Marketing Managers, Trade Show Coordinators, etc.) at US companies. It uses Apollo.io to find contacts and ZeroBounce to verify each email is real and deliverable — so you only send to good addresses.

Step-by-Step Guide
1

Get Your API Keys

You need two API keys to use this app — one from Apollo.io and one from ZeroBounce.

  • Apollo.io (finds contacts) → Go to app.apollo.io → Settings → Integrations → API Keys → Copy key
  • ZeroBounce (verifies emails) → Go to zerobounce.net → Sign up free → Dashboard → API → Copy key
💡 No Apollo API key needed: Apollo search is handled automatically via a connected MCP integration — just open this file in any browser and it works.
⚠️ Never share your API keys with anyone. Paste them directly into the key fields in the app — never in a chat or email.
2

Prepare Your Company List

Create an Excel file with your target companies. Click Download Template on the Find Emails page to get a ready-made file.

  • Company Name column — required (e.g. "Acme Corp")
  • Website column — optional but improves accuracy (e.g. "acme.com")
💡 You can skip the Website column entirely. Apollo will search by company name alone and still finds most contacts.
3

Paste Your API Keys

On the Find Emails page, paste your Apollo key and ZeroBounce key into the key fields. You will see a green "✔ Key entered" message appear — that means it is saved.

💡 Click the 👁 Show button to see what you typed if you want to check for typos.
4

Upload Your File

Click the upload area and select your Excel or CSV file. The app will read your company list and show how many companies it found.

5

Press "Find Emails" and Wait

Click the ▶ Find Emails button. The app will:

  • Search Apollo.io for each company's decision-makers
  • Find their email addresses automatically
  • Verify each email with ZeroBounce
  • Show results live in the table below
💡 The app adds small random delays between requests to behave like a human — this prevents getting blocked. Do not close the window while it runs.
6

Read the Results

Each contact shows a colored status badge:

  • Valid — email is real and deliverable. Safe to send.
  • Catch-all — domain accepts all emails, cannot fully verify. Use with caution.
  • Invalid — email does not exist or will bounce. Do not send.
  • Unknown — could not verify. Use with caution.
💡 For best results, only send campaigns to Valid emails to protect your sender reputation.
7

Export Your Results

Click 💾 Export to Excel to download a clean spreadsheet with all your verified contacts. You can then import this into any email marketing tool (Mailchimp, HubSpot, etc.).

You can also go to the Results page to filter by status before exporting.

Legal Reminder

When emailing US companies, you must comply with the CAN-SPAM Act: always include your company name and address, a clear subject line, and an unsubscribe link in every email. Sending to verified contacts from Apollo's professional database is legitimate B2B outreach.
