Mailchimp | Sync your contacts

The Sinch Engage platform offers a streamlined approach to contact management through its automated integration with Mailchimp.

Contact sync

Contact sync is a one-way automatic sync of contact information from Mailchimp to the Sinch Engage platform. This means any names, phone numbers and emails in your Mailchimp database will be securely imported into your Sinch Engage account - no manual uploads required.

These contacts are clearly marked as "MAILCHIMP" in your contact list to easily distinguish them from contacts added via other sources.

Contact sync occurs every 24 hours - this pulls in the latest updates from your Klaviyo contacts list, including any changes or new entries and reflects them in your Sinch Engage account.

Set up contact sync during installation

Getting started with contact sync is easy when you first connect your Mailchimp account to Sinch Engage. 

1. From the Sinch Engage platform, click on Extensions and then Integrations.
2. Locate the Mailchimp tile and click Install.
3. Click on the Connect button.

4. You’ll be prompted to authorise the connection by logging in with your Mailchimp credentials.

   

5. After you’ve successfully connected your account, follow the next steps to configure SMS Opt in settings.
   • Confirmation notification: This option syncs your selected contacts across as subscribed by default and will send the following confirmation message to alert each contact and provide an opt-out option. 
     • You are subscribed to receive messages from Company Name. Reply STOP to cancel.
   • Double opt-in: This option only syncs a contact after they’ve provided explicit consent by replying Yes to the following confirmation message.
     • Reply Y or Yes to confirm that you want to receive SMS messages from Company Name.

   • None: If your regional legislation allows, you can automatically opt-in your contacts using Inferred (Implied) Consent. This option syncs your selected contacts across without sending a confirmation message.

     Note: The correct opt-in consent option will depend on regional regulations and it’s your responsibility to understand the opt-in requirements for your respective region.

     Each confirmation message sent will incur a cost of 1 credit per contact.

6. If you've got a large contact database in Mailchimp, you can keep the automatic syncing process efficient by only selecting the lists you plan to use for SMS campaigns. This reduces unnecessary data syncing and the need to consistently sync a high volume of data. To do this, select the checkbox next to the contact lists you want to sync with Sinch Engage.
7. Click Next.
8. Map the correct Mailchimp fields and click Sync Contacts to finish.
9. You'll get a confirmation screen when your Mailchimp account has been successfully connected. Depending on the number of contacts to import, you'll be notified as soon as it's complete by email. Click on Done to dismiss the confirmation pop-up.

Enable or modify contact sync for an existing Mailchimp connection

If you've already connected the Mailchimp portal to the Sinch Engage platform, you can enable contact sync or update your previously selected contact lists at any time. To do this:

1. In the Sinch Engage platform, click on Extensions and then Integrations from the left-side navigation bar.
2. Find the Mailchimp tile and click See details.
3. Click on the Contacts tab.

Trigger manual contact sync with Mailchimp

By default, contact syncing between Mailchimp and the Sinch Engage platform happens every 24 hours. You may need to manually trigger contact sync if you need those updates sooner e.g. if you've just updated contact details in Mailchimp and want to use that information right away for an SMS campaign.

You can view your sync status and trigger a manual sync from:

• New Message screen

  

• All Contacts and Contact Lists screen
