The Gmail API free plan allows developers to access a user’s inbox and retrieve emails. This feature is useful for building applications that need to read and analyze emails for specific tasks, such as organizing and sorting messages or triggering automated workflows based on email content.
3. Label Management
With the Gmail API free tier, developers can create, list, and apply labels to emails. This functionality helps organize emails based on predefined categories or user-defined criteria, making it easier to manage and retrieve messages.
4. Email Search
The Gmail API free plan offers email search functionality, allowing developers to search emails based on specific keywords, labels, or other criteria. This feature is beneficial for applications that need to automatically filter and process emails in real time.
5. Email Forwarding
Using the Gmail API free plan, developers can set up automatic email forwarding. This allows incoming emails to be forwarded to specific recipients based on custom rules, which is useful for businesses and email management systems.
6. Send Attachments
Another useful feature available in the Gmail API free plan is the ability to send attachments via email. Developers can include attachments such as images, documents, or files in emails sent through the Gmail API, allowing for more flexible email content delivery.

Developers can access metadata such as email subject, sender, recipient, and timestamps, as well as email threads. This allows for better management and retrieval of email conversations within applications, providing a richer user experience.
8. Read Email Body Content
The Gmail API free tier allows developers to read the body content of emails, including plain text and HTML-formatted content. This is essential for email parsing, content extraction, and building custom email workflows based on email content.

In addition to applying a single label to an email, the Gmail API free plan supports multi-labeling, allowing developers to apply multiple labels to a single email. This makes it easier to categorize and filter emails based on different criteria.
11. Gmail Push Notifications
With the Gmail API free tier, developers can enable push notifications, so they’re alerted when new messages arrive in a user’s inbox. This is great for real-time email-based applications, where it’s important to take immediate action when a new email is received.
