Where Kawaa fits

The problem, and what Kawaa does about it

  1. The problem

    Bounces count against you

    Sending to addresses that no longer exist raises your bounce rate, and a high bounce rate can hurt your sender reputation.

    What Kawaa does

    Dead addresses are caught before the send

    Addresses whose domain or mailbox cannot receive mail come back invalid, and rows that are not valid addresses at all are skipped and counted, so you can leave both out of the campaign.

  2. The problem

    Some servers will not give a straight answer

    Catch-all domains accept every address, and other servers greylist or block verification, so a simple yes or no is not always possible.

    What Kawaa does

    Uncertain results are labeled, not guessed

    Catch-all, risky and unknown addresses are kept apart from valid ones, with a sub-status such as greylisted or policy_block, so you decide how cautious to be.

  3. The problem

    Sign-up forms collect typos

    A subscriber who types gmial.com never gets the welcome email and quietly drops off your list.

    What Kawaa does

    Likely typos come with a suggested fix

    Common domain typos return a suggested correction, so you can fix a real subscriber instead of deleting them.

  4. The problem

    Traps and complainers hide in old lists

    Purchased, scraped or years-old lists can carry spam traps, disposable inboxes and role addresses such as info@.

    What Kawaa does

    Risk flags where they apply

    Disposable, role-based, spam-trap and known-abuse addresses are flagged, and the results download as CSV with a status for every address checked.
