- You want decay protection on your existing list
Pick Debounce if…
- You need the lowest-cost bulk cleanup and do not need deep email platform automation

Honest reasons to pick Debounce.
We are not the right tool for every job. If any of these sound like you, Debounce may be the better pick.
Lowest bulk price is the priority
DeBounce is attractive when the main requirement is getting a CSV checked at a low per-address cost.
The cleanup is occasional
If you only verify a file a few times a year, a budget bulk verifier can be enough.
You do not need no-code automation
Teams that are happy with export and import workflows may not need mailfloss running inside their email platform.
Where mailfloss beats Debounce - by design.
If you are a marketer using Mailchimp, Klaviyo, HubSpot, ActiveCampaign, or another supported email platform, this is where you will feel the difference.
Typo Fixer keeps subscribers other tools delete
When [email protected] arrives, Debounce marks it invalid. mailfloss fixes it to [email protected] and keeps the subscriber on your list. Across a year, that’s real revenue.
It runs on autopilot — not when you remember
Debounce cleans the list when you upload it. mailfloss connects to your email platform once and cleans daily, forever. Most marketers forget to run a verifier every month. mailfloss doesn’t.
Decay Protection catches addresses that rot
Subscribers from 3 years ago go bad on their own. mailfloss re-verifies your existing list on a schedule. Debounce makes you re-upload it.
No CSV gymnastics
With Debounce you export your list, upload, wait, download the results, re-import into your email platform. With mailfloss it’s all happening inside your email platform, automatically. Zero export/import.
Customer-friendly pricing
mailfloss has a money-back guarantee. Debounce doesn’t. If you don’t love it within 7 days, you don’t pay.
No-code for marketers — and a real API for developers
mailfloss is no-code: connect your email platform and it runs. But developers aren’t an afterthought — a modern v1 REST API (bearer-token auth, real-time and bulk verification, and webhooks) exposes the same engine to your code. Most verifiers hand you an API and leave the ongoing cleanup workflow for you to build; with mailfloss you get both.
