Improve your Mailchimp campaign deliverability and engagement rates. ClearBounce identifies invalid, risky, and undeliverable email addresses in your Mailchimp audiences — then exports clean, tagged data back with one click.
Identify invalid and non-existent email addresses before you send. Keep your bounce rate below 2% and protect your sender reputation.
Stop paying Mailchimp to store invalid contacts. Clean your list in minutes and lower your monthly bill by removing dead weight.
Spam traps, disposable emails, and role-based addresses damage your sender score. ClearBounce flags them all before they cause harm.
Connect your Mailchimp account and start verifying in under 2 minutes.
Go to your ClearBounce dashboard, navigate to Verify List, and click the Mailchimp integration. Enter your Mailchimp API key to connect. You can find your API key in Mailchimp under Account → Extras → API Keys.
Choose the Mailchimp audience (list) you want to verify. ClearBounce will import all contacts and begin the verification process automatically.
ClearBounce checks each email for syntax errors, domain validity, mailbox existence, spam traps, disposable addresses, and catch-all servers. Results are categorized as Deliverable, Undeliverable, Risky, or Unknown.
With one click, export your verified results back to Mailchimp. ClearBounce automatically tags each contact with its verification status — so you can create segments for safe-to-send contacts, or filter out invalid and risky addresses before your next campaign.
ClearBounce automatically adds these tags to your Mailchimp audience after verification.
