Google Cloud Platform (GCP) provides various tools and services that developers and organizations can use to set up custom email solutions or integrate email functionality into their applications. Here are some ways you can work with email on Google Cloud:

1. SMTP Relay:

   • Google Cloud offers an SMTP relay service that allows you to send outgoing email from your applications, services, or VM instances through Google’s infrastructure. You can use this service to send transactional emails, notifications, and more.

2. APIs for Email Services:

   • Google Cloud provides APIs and libraries that developers can use to interact with email-related services, such as sending and receiving emails programmatically. For example, the Gmail API allows you to access and manage Gmail accounts and messages.

3. App Engine Mail API:

   • If you are using Google App Engine, it provides an email service that allows you to send email messages directly from your application using the google.appengine.api.mail module.

4. Third-Party Email Solutions:

   • While Google Cloud itself does not provide email hosting for individual email accounts, you can use third-party email hosting services or integrate with existing email services within your applications running on GCP.

5. Google Workspace (Formerly G Suite):

   • Google Workspace is a separate product from GCP but is offered by Google for email and collaboration services. It includes Gmail, Google Drive, Google Docs, and more. Organizations can use Google Workspace for their email and productivity needs.

It’s important to note that if you require email hosting for individual user accounts with features like Gmail, calendar, and document collaboration, you would typically subscribe to Google Workspace or another email hosting service. Google Cloud Platform is primarily focused on cloud infrastructure and developer tools, while Google Workspace provides comprehensive email and productivity solutions for businesses and individuals.
