Qualisend vs DeBounce.
Both verify email addresses down to a real SMTP conversation. DeBounce fits price-sensitive, one-off list cleans where the lowest per-email cost at volume is the priority. Qualisend fits teams that clean regularly and want an API, live progress, a real dashboard and evidence on every verdict. Everything below is sourced and dated - where we haven't verified a DeBounce capability, we say so instead of guessing.
Choose Qualisend if
You clean regularly and want evidence on every verdict, catch-all handling that isn't billed at 10× credits, EU processing, and a real dashboard and API.
Choose DeBounce if
You want the lowest possible price for an occasional one-off clean and don't need a confidence score or a per-address evidence trail.

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.
