Gemini CLI

npm install -g @emailverify/cli
bv config set api-key YOUR_API_KEY

export EMAILVERIFY_API_KEY=your-api-key

I'll run the EmailVerify CLI to check that email.

$ bv verify john@google.com --json

{
  "email": "john@google.com",
  "status": "valid",
  "result": {
    "deliverable": true,
    "disposable": false,
    "role": false
  },
  "score": 0.95
}

The email john@google.com is valid with a 95% confidence score.
It's deliverable and not a disposable or role-based address.

I'll verify each email in your subscriber list.

$ cat newsletter-subscribers.txt | head -5
alice@gmail.com
bob@company.org
test@mailinator.com
jane@outlook.com
invalid@asdfgh.xyz

$ bv verify --file newsletter-subscribers.txt --json > results.json

Processing 500 emails...

Summary:
- Valid: 423 (84.6%)
- Invalid: 52 (10.4%)
- Unknown: 25 (5.0%)

Would you like me to:
1. Create a cleaned list with only valid emails?
2. Generate a report of invalid addresses?
3. Show the emails that need manual review?

#!/bin/bash
# verify-emails.sh - Filter valid emails from stdin

while IFS= read -r email; do
    # Skip empty lines
    [ -z "$email" ] && continue

    # Verify the email
    result=$(bv verify "$email" --quiet 2>/dev/null)
    exit_code=$?

    # Output only valid emails (exit code 0)
    if [ $exit_code -eq 0 ]; then
        echo "$email"
    fi
done

# Usage:
# cat emails.txt | ./verify-emails.sh > valid-emails.txt

### Integration with Google Workspace

**You:** Help me verify the email addresses I'm about to add to my Google Contacts

**Gemini:**

## Shell Functions

Add these to your shell configuration:

```bash
# Quick verify with Gemini
gverify() {
    gemini "Use bv to verify this email and explain the result: $1"
}

# Batch verify with summary
gverify-batch() {
    gemini "Verify all emails in $1 using the bv CLI and provide a summary report"
}

# Check email before sending
email-check() {
    local result=$(bv verify "$1" --quiet 2>/dev/null)
    if [ $? -eq 0 ]; then
        echo "✅ $1 is valid"
    else
        echo "❌ $1 may have issues - running detailed check..."
        gemini "Verify $1 with bv and explain why it might be problematic"
    fi
}

# Before sending a campaign, verify the list
gemini "Read marketing-list.csv, verify all emails in the 'email' column using bv,
and create a new file with only the valid ones"

# Clean up a database export
gemini "Process exported-users.json, verify each email field,
and generate a report of users with invalid emails"

# .github/workflows/verify-emails.yml
- name: Verify test emails
  run: |
    npm install -g @emailverify/cli
    gemini "Find all email addresses in test/fixtures/ and verify them with bv.
    Fail if any real emails are found in test data."

"Verify these emails and output as CSV: email,status,score"

"Why might test@mailinator.com be flagged as invalid?"
