Frequently Asked Questions

Find answers to common questions about our services, features, and processes. We’ve compiled helpful information to guide you through every step.

What does the Stripe Customer Sync for Mailchimp do?

The app automatically migrates your existing Stripe customers into your Mailchimp audience and keeps new customers continuously synced in real time. It transfers customer details, including names, emails, phone numbers, and addresses — with no CSV uploads or manual work.

Does the app automatically sync new Stripe customers?

Yes. Any new customer created in Stripe is auto-synced to Mailchimp instantly.

Is this app free or paid?

The app is free to use.

Does the app migrate products or subscriptions from Stripe?

No. The app is designed specifically to migrate and sync Stripe customers into Mailchimp. Subscriptions, invoices, or products are not synced.

Do customers remain the same in Mailchimp?

Yes. The app keeps their details exactly as they exist in Stripe — while creating or updating corresponding Mailchimp contacts.

What happens if a customer with the same email already exists in Mailchimp?

The app includes built-in duplicate prevention. If the email already exists, the customer is updated instead of duplicated — ensuring a clean, organized Mailchimp audience.

Do I need to install or connect anything on Mailchimp?

No installation needed. You simply authorize Mailchimp through secure OAuth, and the connection is established automatically.

Is my Mailchimp and Stripe data secure?

Yes. The app uses encrypted, OAuth-based authentication and never stores sensitive credentials. You can revoke access anytime with a single click.

Will the app modify my data in Stripe?

No. The process is read-only on Stripe. Your Stripe data is never edited or deleted — only read and synced to Mailchimp.

How long does data migration take?

Migration speed depends on the customer count. Most users can migrate thousands of customers within minutes, and real-time progress is displayed inside the dashboard.

What if the migration stops or gets interrupted?

The app includes an automatic resume. If your browser closes or the internet drops, you can restart and continue exactly where it left off.

What happens if some records fail during migration?

If any record contains invalid data (e.g., a missing email), the app displays the corresponding error returned by Mailchimp, allowing you to review those entries.

Will customers receive any emails or notifications?

No. The sync is completely silent — nothing is sent to your customers automatically.

Do I need technical expertise to use the app?

Not at all. No CSVs, no coding, no API setup. Install the app → connect Mailchimp → start migrating and syncing.

Where can I get support?

If you experience any issues during the migration or syncing process, feel free to report a bug or contact our support team anytime — we’re here to help!
