Hello @mari-lyn ,
Thank you for reaching out to our Support team. The error message means, Brevo is rejecting the API request because the API key is missing, invalid, or misconfigured.
Post SMTP can’t authenticate with Brevo because the API key is missing, incorrect, or invalid. Regenerate the API key, update it in the plugin. You can utilize our documentation for the process.
If further assistance is required feel free to reach out to me.
Warm regards,
Support Team – WP Experts
