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

close Customer support can sometimes be slow to respond
Mails.so

close Newer service with less proven track record
close Limited integration options
Key differences that set them apart
close Bouncer | close Mails.so | |
|---|---|---|
| Pricing Model | Competitive pay-as-you-go pricing with non-expiring credits and volume discounts. | Usage-based pricing with limited credits that can run out quickly for active teams. |
| Validation Speed | Verifies up to 200,000 emails per hour with zero downtime policy. | Slower performance on larger lists compared to more established providers. |
| User Interface | Clean, intuitive interface with features like AutoClean for automatic list cleaning. | Modern and aesthetic but less optimized for bulk workflow operations. |
| API and Integrations | Strong API with good documentation, integrates with HubSpot and other platforms. | Limited native integrations - mostly API-only with basic functionality. |
| Validation Accuracy | Claims 99.5% accuracy with toxicity check and bounce prediction features. | Standard validation without advanced accuracy features for risky emails. |
