There are several ways to inline CSS in your emails:
Manual Inlining: You can manually write the CSS styles directly within the HTML elements. This is time-consuming and error-prone, but it gives you complete control. Automated Tools: Various tools and libraries, such as Litmus Builder, Premailer, and Mailchimp, can automatically inline your CSS for you. These tools save time and reduce the risk of errors. Email Service Providers: Many ESPs (Email Service Providers) offer built-in inlining features that automatically convert your embedded or external CSS into inline styles when you send the email.
