Honestly I was skeptical because the pricing felt too low to be real. We ran a 60k list through VerifyMaill and our previous vendor side by side. The catch-all and disposable detection was noticeably tighter. Bounce rate went from 7.8% to under 1% in about ten days. We've since moved our entire signup verification flow over.

I integrated the API on a Friday afternoon and had it in production before EOD. Docs were clear, the response shape made sense, no weird edge cases. What surprised me more was the inbox placement reporting. That's usually a separate $400/mo tool. Genuinely no notes.

We process around 2M signups a month and our previous provider kept letting through the obvious throwaway domains. Switched to VerifyMaill in Q1 and the disposable catch rate is materially better. Support actually responds. Got a real human on a Slack Connect channel within a day.

We were paying close to $22k/year with one of the top-3 incumbents. Moved to VerifyMaill mostly to cut cost, didn't expect our Gmail placement to actually improve. It did. Saving roughly 70% and our list hygiene reports look better than they ever did. Wish we'd switched a year earlier.

What I keep telling other founders: the free tier is actually usable, not a trial trap. We ran our first 40k validations before paying anything, then upgraded once we had real revenue coming in. Pricing scales the way it should, linearly, no weird cliffs.

I manage deliverability across six newsletter brands and lists go stale fast. The bulk verifier chewed through a 280k list in under ten minutes and the per-ISP placement breakdown told me exactly where we were getting throttled. That kind of visibility used to mean stitching three tools together.
