How we grade them

|---|---|---|
| Value for money | C$50 for a one-off 10,000 checks. Among its listed rivals that's under Bouncer and Emailable ($60) and Kickbox ($70), but DeBounce charges $25. And the credits expire 12 months after purchase, where Bouncer's, Emailable's and DeBounce's never do. | DAbout $129 for a one-off pack of 10,000 checks, or $79 a month billed yearly on ONE for 10,000 credits a month with warm-up and DMARC thrown in. Its listed rivals charge $39 to $70 for 10,000, so even ONE is the dearest way to check a list. |
| Free plan and trial | CNo free plan, but free test credits and a free analysis of your list, with no card. Fine for seeing how messy a list is, not for cleaning it. | CA real free plan: 100 checks a month that refill, plus one inbox test, one server test and one blacklist monitor. You need a business email to get it, and 100 checks won't clean a list. |
| Features | CIt does the checking job fully: bulk cleaning, a real-time API, typo fixes, the company behind each address and automatic Sync. That's a smaller job, though: no warm-up, placement tests or DMARC, and Sync and AI scoring need Growth. | BThe one list cleaner here that touches all three jobs: validation with spam-trap and abuse flags, AI scoring and an email finder, then on ONE, warm-up seeds, 100 inbox tests, blacklist monitors and DMARC reports. DMARC covers just one domain, though. |
| Ease of use | BNo App Store rating on record, but nothing to set up: upload a list and get results, with up to 10 lists cleaning at once on pay-as-you-go. | BNo App Store rating on record. The core job needs nothing set up: upload a list and download it cleaned. There's an iPhone and iPad app for checking lists away from your desk, too. |
