Catching invalid or risky addresses before sending
A standalone verification step ahead of any campaign launch
ZeroBounce is a commonly used verification provider — the same category and purpose as ValidTo, which is the one we've standardized on for our own lists.
We don't rotate between verification providers campaign to campaign, so we can't speak to specific differences from hands-on use — our own lists go through ValidTo by default.
Pricing changes frequently — check ZeroBounce's website for current plans.
We use ValidTo as our standing verification step, so this page stays factual rather than offering a head-to-head opinion we haven't actually tested. If you're comparing verification providers, the category matters more than the specific brand — the point is that every list gets verified before it sends, not which vendor does it.
