Mails.so vs Validity
Comparing two popular email verification services to help you make an informed decision.

close Newer service with less proven track record

Validity

Key differences that set them apart
close Mails.so | close Validity | |
|---|---|---|
| Pricing Model | Usage-based pricing with limited credits that can run out quickly for active teams. | Enterprise contracts with usage-based pricing that requires sales calls and lengthy negotiations. |
| Validation Speed | Slower performance on larger lists compared to more established providers. | Turnaround times can vary significantly depending on your tier and contract terms. |
| User Interface | Modern and aesthetic but less optimized for bulk workflow operations. | Complex interface integrated across multiple data products, steep learning curve. |
| API and Integrations | Limited native integrations - mostly API-only with basic functionality. | Limited flexibility for smaller teams, slower onboarding process. |
| Validation Accuracy | Standard validation without advanced accuracy features for risky emails. | Enterprise-grade validation but often overkill for small to medium businesses. |
