Qualisend vs Bouncer.
Both verify email addresses down to a real SMTP conversation. Bouncer fits EU teams that value the same data-residency posture and want a polished, focused verifier. Qualisend fits teams comparing EU options that want deeper per-address detail, a developer-first API and a lower entry price. Everything below is sourced and dated - where we haven't verified a Bouncer capability, we say so instead of guessing.
Choose Qualisend if
You want the same EU posture with deeper per-address evidence (MX, provider, SMTP reason), a developer-first API, and a lower entry price at $6 per 1,000.
Choose Bouncer if
You want a polished, EU-hosted verifier with deep catch-all detection and a toxicity score, and its pricing and feature set already fit your workflow.

The real difference: what a verdict means
Feature tables hide the philosophical gap. These two are why teams switch to us.
We don't round catch-all up
When a domain accepts every address, no vendor can truly confirm the mailbox - so we say exactly that, show the probe evidence, and let you decide your risk tolerance. Verdicts that quietly upgrade "unverifiable" to "valid" look better in a demo and cost you bounces in production.
Every result shows its work
Each address carries its MX record, inferred provider, and the raw SMTP reason. When a result surprises you, you can see why instead of trusting a black box - which also means you can defend the clean to a client or a deliverability auditor.
