Email Verifier

Simple bulk email verification script using the Reoon Email Verifier API.

What this does

• Reads input leads from input/data.json (an array of objects with an email field).
• Sends emails in bulk to the Reoon bulk verification API.
• Polls for results and writes verified records into output/valid.json and invalid ones into output/invalid.json.
• Supports resuming an in-progress bulk task via output/task-info.json.

Setup

1. Install dependencies (uses Yarn):

yarn install

2. Create a .env file in the project root with your API key:

REOON_API_KEY=your_api_key_here

3. Put your input data in input/data.json.

• The file should contain a JSON array of objects. Each object should include at least an email property, e.g.:

[
  { "email": "alice@example.com", "name": "Alice" },
  { "email": "bob@example.com", "name": "Bob" }
]

Run

Start the script with:

yarn start

This will run email-verifier.js which will process the emails and write outputs to the output/ folder.

Output

• output/valid.json — array of lead objects marked valid
• output/invalid.json — array of lead objects marked invalid
• output/task-info.json — saved task metadata for resumability

Notes

• The script expects input/data.json and writes output files to the output/ directory.
• If you need to restart processing from scratch, remove output/task-info.json.
• The script requires a valid API key with enough credits.

Troubleshooting

• If you see an error about REOON_API_KEY missing, check your .env file is present and correct.
• Ensure input/data.json is valid JSON.
