HTML email is a form of email that uses HTML to format the email's contents. HTML email is different from traditional email because it allows for the email's content to be formatted like a web page. This means that you can use HTML email to create emails that look like they're from a website, and you can even include images and other HTML elements. HTML email is a great way to make your emails stand out from the crowd.
Gmail is a free email service provided by Google. Users can access Gmail on the web and using third-party programs that synchronize email content through the IMAP or POP protocols. Gmail offers users 15 GB of free storage.
Although Gmail provides a basic HTML editor, it is not as comprehensive as some of the other email service providers. If you are looking to create HTML email, you may want to consider using another service.
