B2b Email Verifier

What does it do?

B2B Email Verifier validates email addresses in bulk by checking multiple verification layers. It verifies email format, checks DNS MX records to confirm the domain accepts email, tests SMTP connectivity to validate the specific mailbox, detects disposable and temporary email addresses, identifies catch-all domains, and calculates an overall deliverability score.

Why use this scraper?

Clean email lists are essential for successful B2B outreach. Sending to invalid addresses damages your sender reputation, increases bounce rates, and can get your domain blacklisted. This tool helps you clean your email lists before campaigns, verify leads from web scraping, and ensure data quality in your CRM. Unlike simple syntax checkers, it performs real DNS and SMTP-level verification.

How to use it

1. Go to B2B Email Verifier on Apify Store
2. Click "Try for free"
3. Enter email addresses to verify (one per line)
4. Click "Start" and wait for the results
5. Download your verified email list in JSON or CSV format

You can also use the Apify API to run the verifier programmatically and integrate it into your workflow.

Cost of usage

B2B Email Verifier uses pay-per-event pricing. Each verification costs approximately $0.00075 (about $0.75 per 1,000 emails). The Apify Free plan provides $5/month of platform credits.

Tips

• Deliverability scores above 70 indicate likely valid addresses
• Catch-all domains accept all addresses, so individual mailbox validation is not possible
• Disposable email addresses are flagged and should be excluded from B2B campaigns
• Free provider emails (Gmail, Yahoo) are flagged separately from business domains
• Process emails in batches to avoid rate limiting from mail servers
• SMTP verification may be blocked by some corporate firewalls
