    MailCull is an email verification tool that cleans your contact lists before you hit send, so your messages reach real inboxes instead of bouncing.

    Upload a CSV and MailCull culls the dead, risky, and fake addresses from your list. Every email comes back with one of four clear verdicts: deliverable, risky, undeliverable, or unknown. No vague scores, no guesswork.

    How it works:

    - Quick scan checks formatting, typos, disposable domains, and mail-server (MX) records in seconds.

    - Deep scan goes further and connects to each mailbox over SMTP to confirm it can actually receive mail, with catch-all detection built in.

    Across real-world lists, MailCull lands around 91 to 93 percent accuracy, and it tells you honestly when an address is genuinely unknown instead of pretending to be sure.

    Why it matters: a clean email list means lower bounce rates, a healthier sender reputation, better inbox placement, and no money wasted emailing addresses that were never going to open.

    What you get:

    - Bulk email list verification and cleaning (CSV in, clean list out)

    - Single email address checks

    - Four clear verdicts you can act on

    - Free tools: email verifier, blacklist monitor, MX lookup, SPF, DKIM and DMARC checkers, plus catch-all and disposable detection

    - A developer API to verify email addresses right inside your own signup flow or app

    - Clean exports you can drop straight back into your sending platform

    Who it is for: marketers, founders, sales teams, and developers who want fewer bounces and more emails landing in the inbox.

    Start free, then upgrade when you need more volume.
