How we grade them
| 2.4GPANeverBounceFair | 2.4GPAProofyFair | |
|---|---|---|
| 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. | B$5 for 5,000 credits, under the $8 middle for one-time prices in the category. The page shows no price for larger packs or subscriptions. |
| Free plan and trial | CNo free plan, but free test credits and a free analysis of your list, with no card. That shows how messy a list is; it won't clean it. | DNo free plan and no free trial. There is a free single-address checker, but a list costs the $5 pack. |
| 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. | BBulk verification, an API, a widget and webhooks, with risk and type detection. Catch-all servers can still return Risky or Unknown. |
| 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. | CNo store rating on record. You upload a list or wire up the API, a few steps. |
| Platforms and integrations | BWeb and an API, with HubSpot, Mailchimp, Zapier, n8n, Marketo, Oracle Eloqua, Constant Contact and AWeber. No phone or desktop app. | BWeb dashboard and API, with a widget and webhooks. No integrations or apps are listed. |
| Best for | keeping a CRM's contacts checked automatically | cheap email list checks by the credit |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
