Bouncer is a solid mid-range email verification service with competitive per-email pricing and good speed. It offers a clean interface and reliable results but lacks catch-all probability scoring and a free tier. VeriMails matches Bouncer's quality at a lower price point while adding catch-all scoring that Bouncer doesn't offer.
| Feature | VeriMails | Bouncer |
|---|---|---|
| Price per email | $0.0029 | $0.002-$0.007 |
| Free tier | 50/day forever | None |
| Catch-all handling | Probability scoring (0-100) | Binary flag |
| API | REST API | REST API |
| Bulk verification | Fast CSV processing | CSV upload |
| Speed | Sub-2 second | Fast |
Bouncer delivers reliable verification with syntax, DNS, MX, and SMTP checks. Their accuracy for standard mailboxes is on par with industry leaders. They also offer a 'Toxicity Check' feature that identifies potentially harmful addresses (spam traps, complainers, etc.), which is a useful addition. However, catch-all domains still get the standard binary treatment. VeriMails matches Bouncer's core verification accuracy and adds catch-all probability scoring. While we don't offer a toxicity check equivalent, our catch-all scoring addresses a larger and more common problem: the 20-40% of B2B addresses on catch-all domains that most verifiers can't score.
Bouncer handles catch-all domains the same way most competitors do: flag them and let you decide. Their documentation recommends either including all catch-all addresses (accepting higher bounce risk) or excluding them all (losing valid leads). VeriMails eliminates this trade-off with probability scoring. Instead of an all-or-nothing decision on catch-all addresses, you get a confidence score for each one. This is the difference between guessing and making data-driven decisions about your email list.
Bouncer's API is straightforward and well-documented with support for single and batch verification. Response times are competitive, and the API is suitable for real-time use. They offer integrations with popular email marketing platforms. VeriMails' API is similarly clean and fast. Both services are developer-friendly. The key difference is that VeriMails' API responses include catch-all probability scores at no extra cost, giving you richer data per API call.
Bouncer's pricing is competitive, ranging from $0.002 to $0.007 per email depending on volume. Their lowest published rate of $0.002/email requires very high volume commitments. For typical volumes, expect $0.003-$0.005/email. At 10,000 emails, Bouncer costs $30-$70. At 100,000 emails, $200-$500. VeriMails Pro at $0.0029/email is at the low end of Bouncer's range. At 10,000 emails, VeriMails costs $29 vs Bouncer's $30-$70. At 100,000 emails, VeriMails is roughly $290 vs $200-$500. For most volume tiers, VeriMails is cheaper or comparable, with the added benefit of catch-all scoring and a free tier.
| Volume | VeriMails | Bouncer |
|---|---|---|
| 10,000 emails | $29 | $30-$70 |
| 100,000 emails | ~$290 | $200-$500 |
Teams that need catch-all probability scoring (which Bouncer doesn't offer). Users who want a permanent free tier for testing. Developers looking for the best price-to-feature ratio. Anyone verifying B2B lists where catch-all domains are common.
Teams that value the toxicity check feature for identifying spam traps and serial complainers. Users who need native integrations with specific email marketing platforms. Organizations already invested in the Bouncer ecosystem.
Core verification accuracy is comparable. Both use real SMTP verification and deliver reliable valid/invalid results. The main difference is catch-all handling: Bouncer gives you a binary flag, VeriMails gives you a probability score.
Yes. Bouncer offers a 'Toxicity Check' that identifies potential spam traps, serial complainers, and other risky address types. VeriMails doesn't currently offer this specific feature. However, VeriMails' catch-all scoring solves a more common problem for most users.
At very high volumes, Bouncer's lowest rate ($0.002/email) can be slightly cheaper than VeriMails ($0.0029). But at typical volumes (10K-100K/month), VeriMails is equal or cheaper. Plus, VeriMails includes catch-all scoring and a free tier at no extra cost.
Yes. Some teams use Bouncer for toxicity checking and VeriMails for verification with catch-all scoring. This combined approach gives you the best of both services.
