Familiarize yourself with the API's rate limits, request sizes, and other restrictions. This helps you plan your email campaigns effectively and avoid any potential issues.

Regularly clean and update your email lists to ensure you're only sending to engaged and valid email addresses. This improves deliverability and reduces the risk of being marked as spam.
