This article explains how to resolve email template errors in Smartr365 caused by an invalid or deactivated MailChimp API key.
Overview
Smartr365 allows firms to integrate with MailChimp for email templates and campaigns. If the MailChimp API key has expired, been revoked, or is otherwise invalid, email templates will display errors and cannot be used until the integration credentials are updated.
Symptoms
Email templates show an error when loading or in use
Templates that previously worked are no longer loading correctly
The error references the MailChimp integration or an external email service
Resolution Steps
Log in to Smartr365 and navigate to Settings > Business Settings (or Integrations, depending on your configuration).
Locate the MailChimp integration section.
Log in to your MailChimp account separately and generate a new API key:
In MailChimp: Account > Extras > API Keys
Click Create A Key and copy the full key
Paste the new API key into the MailChimp integration field in Smartr365 Business Settings and save.
Return to your email templates and confirm they load correctly.
Common Issues
No access to the MailChimp account: Ensure you have administrator access to the MailChimp account linked to your firm. If access has been lost, contact your firm's IT administrator or MailChimp support.
Error persists after updating the key: Confirm the key was copied in full with no extra spaces. Try logging out and back in to Smartr365. If the issue continues, contact Smartr365 support.
MailChimp account is deactivated: If the MailChimp account itself has been closed, you will need to reactivate it or create a new MailChimp account and re-link it in Smartr365 Settings.
