A strong pay-as-you-go option if you value expiring-never credits over a subscription.
ZeroBounceZeroBounce
Good if you need inbox-health tools too; pricey if you only clean lists now and then.
KickboxKickbox
Good fit for pay-as-you-go verification; not a subscription product or a proven crowd favorite here.
