By creating and storing templates, you can ensure that your emails are always on-brand and error-free. Aotsend suggests using dynamic templates to personalize your emails further.

To avoid hitting rate limits and ensure smooth API interactions, implement rate limiting and throttling in your application. The SendGrid V3 API documentation provides clear guidelines on rate limits, so make sure to adhere to them. Aotsend also highlights the importance of monitoring your API usage to avoid unexpected disruptions.
