What is Mailchimp?

However, Mailchimp's effectiveness depends heavily on the quality of your email list. Invalid email addresses can sabotage your campaigns and damage your sender reputation—which is where our email verification service comes in.
Why Integrate BillionVerify with Mailchimp?
While Mailchimp excels at sending emails, it doesn't verify email addresses before adding them to your audience. If your email lists contain invalid addresses, you'll face serious problems:
❌ High Bounce Rates: Invalid emails cause bounces, damaging your sender reputation with Mailchimp
❌ Wasted Budget: You're paying Mailchimp for contacts that don't exist
❌ Low Engagement: Poor data quality leads to inaccurate campaign analytics
❌ Deliverability Issues: ISPs may flag your domain as spam if bounce rates are high

FAQ About Mailchimp Integration
How does this integration work with Mailchimp?
The BillionVerify + Mailchimp integration works via API. When someone subscribes to your Mailchimp audience, our API verifies the email in real-time (less than 1 second). Valid emails are kept active, invalid ones are unsubscribed or tagged for review.
Will it slow down my Mailchimp forms?
No. BillionVerify's API responds in less than 1 second on average. For even faster performance, you can use asynchronous validation (verify after form submission) or enable caching for previously verified emails.
