The SendGrid API offers various endpoints to manage email campaigns, contacts, and more.

2. Set Up Your SendGrid Account Correctly

To get started, create a SendGrid account and obtain your API key. This key will be used to authenticate your requests to the API. Ensure that your account is properly configured, including setting up email authentication and domain verification, to enhance deliverability and avoid spam filters.

Protect your SendGrid API key like you would any other sensitive credential. Avoid hardcoding it into your application and consider using environment variables or a secure credential store to manage it.
