Gmail for PowerShell

A PowerShell module for managing your Gmail, with all the tools you'll need. Search, read and send emails, archive, mark as read/unread, delete emails, and manage labels.

This library is still under development.

Installation

You can install it easily using chocolatey:

cinst Gmail.ps

Or install it manually:

git clone https://github.com/nikoblag/Gmail.ps.git
cd Gmail.ps
.\install.ps1

Features

• Read emails
• Search emails
• (Update) emails: label, archive, delete, mark as read/unread/spam, star
• Manage labels
• Move between labels/mailboxes
• Automatic authentication, using the Windows Credential Manager

Usage:

Authenticating Gmail sessions

To authenticate a Gmail session, use New-GmailSession and provide your username and password. If you want to be automatically logged in to your account, create a generic credential using the Windows Credential Manager: go to 'Control Panel\User Accounts and Family Safety\Credential Manager', click 'Add a generic credential', then type your Gmail username and password, and use Gmail.ps:default as address.

PS> $gmail = New-GmailSession
PS> # play with your gmail...
PS> $gmail | Remove-GmailSession

If you use Invoke-GmailSession and pass a block, the session will be passed into the block, and will be logged out after it's executed. Use $args to access the session or parameterize the block:

PS> Invoke-GmailSession -ScriptBlock {
PS>     param($gmail) # to use $gmail instead of $args
PS>     $gmail | Get-Label
PS> }

You can also check which accounts are logged in at any time:

PS> Get-GmailSession

Gathering emails

Get the messages in the inbox:

PS> $gmail | Get-Mailbox
PS> $gmail | Get-Mailbox | Filter-Message -Unread

Get the messages marked as Important by Gmail:

PS> $gmail | Get-Mailbox "Important"

With Get-Mailbox you can access the "All Mail", "Starred", "Drafts", "Important", "Sent Mail" and "Spam" folders

Filter with some criteria:

PS> $gmail | Get-Mailbox | Filter-Message -After "2011-06-01" -Before "2012-01-01"
PS> $gmail | Get-Mailbox | Filter-Message -On "2011-06-01"
PS> $gmail | Get-Mailbox | Filter-Message -From "x@gmail.com"
PS> $gmail | Get-Mailbox | Filter-Message -To "y@gmail.com"

Combine flags and options:

PS> $gmail | Get-Mailbox | Filter-Message -Unread -From "myboss@gmail.com"

Browsing labeled emails is similar to working with the inbox.

PS> $gmail | Get-Mailbox -Label "Important"

You can count the messages too:

PS> $gmail | Get-Mailbox | Filter-Message -Unread | Count-Message
PS> $gmail | Count-Message

Also you can manipulate each message using block style. Remember that every message in a conversation/thread will come as a separate message.

PS> $messages = $gmail | Get-Mailbox | Filter-Message -Unread | Select-Object -Last 10
PS> foreach ($msg in $messages) {
>>     $msg | Update-Message -Read # you can use -Unread, -Spam, -Star, -Unstar, -Archive too
>> }

Working with emails!

Delete emails from X:

PS> $gmail | Get-Mailbox | Filter-Message -From "x@gmail.com" | ForEach-Object { Remove-Message $_ }

Save all attachments in the "Important" label to a local folder:

PS> $messages = $gmail | Get-Mailbox -Label "Important" | Get-Message
PS> foreach ($msg in $messages) {
>>     if ($msg.HasAttachments) {
>>         $msg.FetchAttachments($folder)
>>     }
>> }

Save just the first attachment from the newest unread email:

PS> $msg = $gmail | Get-Mailbox | Filter-Message -Unread | Select-Object -Last 1
PS> $msg.Fetch()
PS> $msg.Attachments[0].SaveTo($location)

Get all labels applied to a message:

$msg | Get-Label

Add a label to a message (or remove it):

$msg | Set-Label "Important"
$msg | Remove-Label "Important"

You can apply multiple lables:

$msg | Set-Label "Important","Banking"

The example above will raise error when you don't have one of the specified labels. You can avoid this using:

$msg | Set-Label "Important","Banking" -Force # If one of the labels does't exist, it will be automatically created now

You can also move message to a label/mailbox:

$msg | Move-Message -Label "Test"
$msg | Move-Message "All Mail"

Managing labels

With the Gmail module you can also manage your labels. You can get list of defined labels:

$gmail | Get-Label

Create new label:

$gmail | New-Label -Name "MyLabel"

Remove labels:

$gmail | Remove-Label -Name "MyLabel"

Or check if given label exists:

$gmail | Get-Label -Name "SomeLabel" # returns null if the label doesn't exist
