How to make read mail unread in gmailk

To mark a read email as unread in Gmail, you can follow these steps:

Method 1: Using the Gmail Web Interface

  1. Log in to your Gmail account.
  2. Open the email you want to mark as unread.
  3. Click on the checkbox next to the email subject to select it.
  4. Click on the "More" menu at the top of the page.
  5. Select "Mark as unread" from the dropdown menu.

Method 2: Using the Gmail Mobile App

  1. Open the Gmail app on your mobile device.
  2. Open the email you want to mark as unread.
  3. Tap the three vertical dots at the top right corner of the screen.
  4. Tap "Mark as unread" from the dropdown menu.

Method 3: Using Keyboard Shortcuts

  1. Log in to your Gmail account.
  2. Open the email you want to mark as unread.
  3. Press the "U" key on your keyboard. This will mark the email as unread.

Note: You can also use the "Shift + U" shortcut to mark multiple emails as unread at once.

Method 4: Using the Gmail API

If you're using the Gmail API to access your emails programmatically, you can use the "ModifyThread" method to mark an email as unread. Here's an example of how you can do this using the Gmail API client library for Python:

from googleapiclient.discovery import build

# Create a Gmail API client instance
service = build('gmail', 'v1', developerKey='YOUR_API_KEY')

# Set the thread ID of the email you want to mark as unread
thread_id = 'thread_id_here'

# Set the label ID of the label you want to apply to the email
label_id = 'label_id_here'

# Mark the email as unread
service.users().threads().modify(userId='me', id=thread_id, body={'addLabelIds': [label_id], 'removeLabelIds': []}).execute()

Replace YOUR_API_KEY with your actual API key, thread_id_here with the ID of the thread you want to mark as unread, and label_id_here with the ID of the label you want to apply to the email.
