QuickEmailVerification

QuickEmailVerification is a long-standing email verification service that checks addresses in bulk, one at a time or in real time through its API. It removes invalid, disposable and role-based addresses and flags risky ones so you can protect your sender reputation before a campaign goes out.

Its standout feature is a permanent free tier of 100 verification credits every day, which is enough to spot check small lead lists, test the API or verify contacts as they come in without paying. Paid plans come in two forms. Persistent credits are bought once and never expire, and Per Day Credits plans are monthly subscriptions that give you a set number of verifications each day, which suits teams processing new leads daily.

It is a simple, dependable option for freelancers and small outbound teams that want free daily checks and low prices when they need more.

The free tier gives 100 credits a day with no card required. Pay-as-you-go credits start at about $4 for 500 verifications, with lower prices per email at higher volumes and custom plans available.
