What is the difference between Google Workspace Gmail and free Gmail?
Google Workspace Gmail is the paid version of Gmail that is designed for businesses and organizations. It includes a range of additional features and services beyond what is available in free Gmail, such as custom email domains, increased storage capacity, advanced security and compliance options, and access to Google’s suite of productivity tools like Google Docs, Sheets, and Slides.
One of the key differences between Google Workspace Gmail and free Gmail is the availability of SMTP (Simple Mail Transfer Protocol) service. SMTP is the protocol used to send email messages between servers, and it is essential for businesses that need to send large volumes of email or want to customize their outgoing email messages.
With Google Workspace Gmail, SMTP service is available to all users, and they can use it to send email messages from their custom domain name. This allows businesses to maintain a professional image and build trust with their customers by using their own branded email address.
In contrast, free Gmail does not provide SMTP service by default. This means that while you can use Gmail to send emails from within Gmail itself, you cannot use it to send emails from other environments, such as WordPress. This is where you would use 
third-party SMTP services.
Overall, the key difference between Google Workspace Gmail and free Gmail in terms of SMTP service is that Google Workspace Gmail provides a more comprehensive set of email services that are tailored to the needs of businesses and organizations, including full access to SMTP service.
