Manual cleanup vs mailfloss for Mailchimp.
Doing this yourself isn’t hard. It’s just tedious, error-prone, and never-ending. Here’s what changes when you connect mailfloss.
mailfloss fits the way Mailchimp teams clean lists.
No “not supported in Mailchimp” footnotes. Same product, no caveats.
Typo Fixer
Recognizes 250+ typo patterns and quietly fixes them in your Mailchimp list. Recovers subscribers other verifiers would silently delete.
Instafloss
Blocks fake, invalid, and disposable emails the instant they’re submitted to your Mailchimp signup form. Real-time, no waiting.
Autofloss
Runs daily, scanning every new Mailchimp subscriber from the last 24 hours and removing anything that didn’t survive validation.
Decay Protection
Sweeps your entire Mailchimp list on a schedule you set, removing addresses that have rotted since they joined.
Custom Keep & Remove Rules
Whitelist VIPs you never want auto-removed, blacklist domains you never want on your list. Per-Mailchimp-audience overrides too.
Auto-Actions
Tell mailfloss what to do with a bad address — remove it from Mailchimp, archive it, tag it, or fire a webhook.
