Detect spam subscribers before they damage your list

Scan your audience for suspicious email addresses and flag them directly in your spreadsheet — no third-party tools needed.

Starter plan & above

List bombing is real. Clean your audience in one click.

Spammers subscribe fake and disposable emails to mailing lists to abuse signup flows. Detect Spam scans every email in your sheet against known patterns — and highlights the suspicious ones in yellow so you can review and remove them.

Manage multiple Mailchimp audiences from one sheet

Each audience used to mean its own CSV cycle. Not anymore.

All plans

Switch audiences in seconds — sync each one independently

If you manage lists for multiple projects, clients, or segments, every audience is a separate export, import, and error-check cycle. Sheets2Mailchimp lets you select any of your Mailchimp audiences and sync directly from your sheet — no re-importing, no format juggling.

Tag your subscribers in Sheets. They sync to Mailchimp automatically.

Manually tagging contacts in Mailchimp one by one is tedious. Wrestling with CSV import tag formats is worse. Add a Tags column to your sheet — comma-separated values sync directly to Mailchimp tags on every sync.

Tags update on every sync
