Methodology

We compared the cost per credit across major enrichment providers using their publicly available pricing. Here's how we conducted our research and validated our results.

Pricing Data

All pricing data was collected from publicly available sources in January 2025. We used mid-tier pricing plans for fair comparison, as these represent the typical customer segment for B2B data enrichment.

Verification Method

Every email we return goes through a multi-step verification process. This is how we achieve 94%+ accuracy while keeping costs dramatically lower than competitors.

1

Pattern Recognition

Our AI analyzes company email patterns from multiple public sources to predict email formats with 95%+ accuracy.

2

SMTP Validation

Every predicted email is verified against the mail server using SMTP handshake without sending actual emails.

3

Deliverability Check

We check for catch-all domains, spam traps, and disposable email patterns to ensure real deliverability.

4

Fallback Providers

Only when our direct methods can't verify, we use premium providers - passing the cost savings to you.

How SMTP Validation Works

1. DNS Lookup: We query the MX records for the domain to find the mail server.

2. Connection: We establish an SMTP connection to the mail server.

3. RCPT TO Check: We send a recipient check command without actually sending an email.

4. Response Analysis: Based on the server response, we determine if the mailbox exists.

5. Catch-all Detection: We test for catch-all domains that accept all addresses.
