5. Sending the Email Using Gmail API
After setting up the email message, it's time to send it! You’ll use the Gmail API’s users.messages.send method to send the email with attachments.

This is an important aspect of the Gmail API send email with attachment PHP process, and it’s one step you don’t want to overlook!
6. Handling Attachments Properly
Sending Gmail API send email with attachment PHP emails requires handling attachments with care.
