MailVet vs Kickbox
Kickbox gets an answer from the mail server and MailVet doesn't. If you need to know a specific address exists, pick Kickbox.
The facts
| Fact | Kickbox | MailVet |
|---|---|---|
| Mailbox check over SMTP | Yes. rejected_email means the SMTP server rejected it and the address doesn't exist. | No. MailVet never contacts the mailbox, so it can't tell you one exists. |
| Catch-all detection | Yes, accept_all. | No. That takes an SMTP probe. |
| Disposable domains | Yes, disposable. | Yes, from open lists refreshed daily. Domains not on them yet can get a suspect signal, with partial coverage. |
| Role addresses | Yes, role. | Yes, role. |
| Typo suggestions | Yes, did_you_mean. | Yes, did_you_mean, for typos of big providers. |
| Quality score | Yes, sendex, from 0 to 1. | None. A verdict and a reason. |
| Addresses stored | Not compared. Read their privacy policy. | No. Our app doesn't store or log addresses, only the domains it has seen. Send them by POST to keep them out of URLs and host logs. |

We couldn't read kickbox.com, so this page has no Kickbox price, free tier or limits. Those are on their site. What's above comes from the README of their official Node client, which may lag their current API.
Pick Kickbox if
- You need to know whether a specific mailbox exists.
- You want a quality score per address, not only a verdict.
- You want catch-all domains called out.
Pick MailVet if
- You want to stop throwaway and mistyped addresses at a signup form.
- You want a flat monthly plan with a hard cap. Compare that with their pricing, which we couldn't read.
- You want a check that never touches the recipient's mail server.
