Why did I receive an Apex exception email about McMemberBatch and "No response from Mailchimp"?
Getting an Apex exception email from Salesforce can be alarming, especially when it references a batch job you didn't manually trigger. If you've seen an error mentioning mone.McMemberBatch and the message "No response from Mailchimp," the good news is this is almost always caused by a temporary Mailchimp outage and not a problem with your MC4SF installation.
The McMemberBatch job is responsible for pulling member data from Mailchimp into Salesforce. When Mailchimp is temporarily unreachable, the job retries several times before giving up, and Salesforce sends an exception email to the org admin to let you know the batch didn't complete. This is standard Salesforce platform behaviour for failed batch jobs.
The Solution
When you receive this error, it means Mailchimp was temporarily unavailable at the time the batch ran. The integration will automatically catch up on the next scheduled execution, so in most cases no action is needed.
If you're concerned that some member data may have been missed during the outage, you can trigger a manual sync to bring everything up to date:
- Open the Mailchimp for Salesforce app in Salesforce
- Navigate to the Data Wizard tab
- Run a full sync for the relevant audience
If the error continues to appear outside of a known Mailchimp outage period, please contact Beaufort 12 support as there may be a connectivity issue with your integration.
