Using Filters in Gmail to Organize Incoming Mail

Did you know you can use filters to automatically label, archive, delete, star, or forward your mail based on keywords, senders, recipients, and more? Start to organize your mail with these simple steps.

To create a new filter:

  1. In Gmail go to Settings (at the top-right under the gear icon) --> Filters and Blocked Addresses --> Create a new filter
  2. Enter your filter criteria in the appropriate field(s). You can enter information in one or several fields to specify what to filter:
    • "From" - emails from a specific email address
      (ex. ", another personal address you have set up to forward, or an E-newsletter you receive)
    • "To" - emails sent to a specific address
      (ex. ", or a listserve you belong to)
    • "Subject" - any emails with keywords in the subject
      (ex. "Open House" or "Seminar")
    • "Has the words" - any emails with these keywords in the body of the email
      (ex. a grant number or the name of a class you are taking)
    • "Doesn't have" - any emails without keywords
  3. Click Create a new filter.
  4. Select one or more actions from the list. These actions will be applied to messages matching your filter criteria in the order in which the actions are listed
    • For example, choose to apply a certain label to your filtered emails so it places them in categories (like folders); or you could choose to Forward matching messages to a specific email address, then Delete the messages; or you could send certain messages directly to the archive so that they don't clutter up your inbox.
  5. If you'd like to apply this filter to messages already in Gmail, select the checkbox "Also apply filter to x matching conversations".
  6. Click Create Filter.


To create a filter from within a message:

  1. Click the drop-down menu (three vertical dots on the upper right).
  2. Select Filter messages like this.
  3. Enter your filter criteria in the appropriate field(s) as described above.


To edit or delete existing filters:

  1. Click Settings --> Filters and Blocked Addresses.
  2. Find the filter you'd like to change and click its edit link, or click delete to remove the filter.
  3. If you're editing the filter, enter the updated criteria for the filter in the appropriate fields, and click Next Step.
  4. Update any actions and click Update Filter.

You can create an unlimited number of filters, but only 20 filters can forward to other addresses. You can maximize your filtered forwarding by combining filters that send to the same address. More information on this topic can also be found here.


Free Up Space in your Gmail Account

WARNING!: Before deleting any email messages or attachments from your Gmail account, be sure to backup any important email messages to your computer using an email client or Gmail Backup. Instructions for backing up email messages are located here.

There are a few different methods to free up space in your Gmail account:

  1. Use the Gmail web interface (described below)
  2. Use IMAPSize to delete large attachments (Windows only)
  3. Use an email client - see this Knowledge Base post: Delete Batches of Email Using an Email Client

Delete messages using the Gmail web interface: The easiest and fastest way to free up space in your Gmail account is to delete batches of email messages within a specific date range using the web interface

  1. Login to your Gmail account:
  2. Click the All Mail link on the left side of the page.
    (You may have to click the "more" link for the All Mail link to be visible)
  3. Enter the date range in the search box in the following format: before: YYYY-MM-DD
    (For example to search for mail from 2008 and earlier, enter: "before: 2009-01-01")
  4. Click the Select All link (the little blank box with downward arrow in the upper-left corner of the panel), then click the Select all conversations that match this search link
  5. Click the Delete button to delete all email messages contained within the date range of the search. The email messages are then moved to the Trash.
  6. Click the Trash link, then click Empty Trash now.
  7. Click OK to confirm.


To free up space in your local email client software, and avoid duplication, when syncing from gmail:

  1. Navigate to the gear icon at the top right. Click it.
  2. In the menu that drops down, click Settings.
  3. Go to the tab Forwarding and POP/IMAP.
  4. In the "IMAP Access" confirm that IMAP is Enabled.
  5. Now, go to the Labels tab.
  6. Uncheck the Show in IMAP box to the right of All Mail
  7. These settings should autosave, exit the settings dialog.
  8. Get Mail or the equivalent, from your mail client software. This should now sync, and keep your mail client from downloading duplicate emails.

Exporting Gmail Contacts

You can quickly export your Gmail Contacts list into a downloadable file. Here's how:

  1. Go to Google Contacts.
  2. From the More drop-down menu, select Export....
  3. Choose whether to export all contacts or only one group.
  4. Select the format in which you'd like to export your contacts' information. Please note, some of these formats can lose some contact information.
    • To transfer contacts between Google accounts, use the Google CSV format. This is the recommended way to back up your Google Contacts.
    • To transfer contacts to Outlook, Yahoo! Mail, Hotmail, or various other apps, use the Outlook CSV format.
    • To transfer contacts to Apple Address Book, use the vCard format.

How do I attach a signature in Gmail?

Gmail signatures are text that appear at the footer of your email message. Email signatures can be tested by composing a new email message. Your signature should appear at the bottom of your email message.

For more information on creating a Gmail signature click here.


How do I keep certain emails from ending up in Junk Mail in Gmail?

You can 'whitelist' an email address to ensure it is not marked as Junk Mail by Gmail.

In Gmail, if a message is inappropriately identified as spam, you can unmark the message. Just select the message, and click the "Not Spam" button that appears at the top and bottom of your current view. Marking a message as "Not Spam" will result in the email message being automatically moved to your Inbox.

Alternatively, if you would like to prevent this in the future, you can add the sender's email addresses to your Contacts list. Click here for instructions to import your contacts into Gmail.


How does Gmail filter spam and viruses?

According to Google's website:

"Google has one of the best spam blockers in the business, and it's integrated into Google Apps. Spam is purged every 30 days. We have built in virus checking, and we enforce checking of documents before allowing a user to download any message. Most computer viruses are contained in executable files, so standard virus detectors scan messages for executable files that appear to be viruses. Google blocks viruses in the most direct possible way: by not allowing users to receive executable files (such as files ending in .exe) that could contain damaging executable code; even if they are sent in a compressed (.zip, .tar, .tgz, .taz, .z, .gz) format."

For more information on how Google filters Spam and viruses please see the Google Security Services website.

Can I create folders in Gmail?

Unfortunately, Gmail does not currently support folders. There are two ways you can manage emails.

Using an email client:

You can create folders and manage your email using an email client on your personal computer. Then sort all of your email into organized/categorized folders or a single folder in an email client and only leave email messages in your inbox that you are currently using.

Using SJSU Gmail:

Gmail allows you to "label" your email messages to help you sort your email into categories. If you would like to see all emails under a certain label, the categories can be found on the left hand side under "Labels". Once messages are labeled, you can archive these emails. Archiving messages moves them out of your "Inbox" abut they remain in "All Mail", letting you tidy up your inbox without deleting anything. You can also speed up your inbox by moving messages into your "Archive".

For information on creating and managing labels in Gmail, please refer to the Google Apps Help Center, "Labeling Mail" help topic, Click here.

  4. Select one of the options listed:
    New mail notifications on ← Recommended

Email Client Software

Where does my email client store my email?


Outlook: C:\Users\<username>\AppData\Local\Microsoft\Outlook

Mac OS X:

Eudora: /Macintosh HD/Users/<username>/Library/Qualcomm/Eudora/
Entourage 2004: /Macintosh HD/Users/<username>/Documents/Microsoft User Data/Office 2004 Identities/Main Identity/
Entourage 2008: /Macintosh HD/Users/<username>/Documents/Microsoft User Data/Office 2008 Identities/Main Identity/

Email Client Software

Email Configuration: IMAP or POP3?

Use POP if you...

...are the type of computer user who will only access your email using one email client (in this case Outlook). This way all your email is downloaded to you computer and you will always have access to your email whether you are online or offline. (If you use this setting, I recommend that have a robust backup system, since the only copy of your email will reside on your personal computer. You can configure Outlook to leave a copy of your email on the server, but you have a limited amount of storage on the server, so your email box could reach capacity and you will no longer receive email until you free up space.

Follow the instructions in the following link for steps to configure POP.

Use IMAP if you...

...access your email from multiple locations or devices and you are confident that you can configure your email settings properly. The IMAP email protocol enables a user to access their email from multiple interfaces while maintaining the presence and status of all the emails in your account (i.e. read vs un-read, replied/forwarded, deleted/moved/sorted, etc.). This is essential if you access your email from your computer in your office, your computer at home, your smartphone, a web browser on a shared computer, etc. The thing about IMAP is that you need to make sure it's configured to download the entire email message and attachments and you'll want to backup your emails to the local hard drive on one of your computers (gmail offers backup guarantees, but they are limited). I recommend IMAP to most computer users. It's especially helpful if you don't have access to your computer for some reason (because it crashed, or you forgot your power supply, or your dog ate it).

Follow the instructions in the following link for steps to configure IMAP.

Please remember that these are simply my personal preferences and recommendations, you are responsible for configuring, maintaining and backing up your own email. I cannot take responsibility for lost email or other problems that can result from improperly configured email clients.

Delete Batches of Email using an Email Client


You can Delete email messages from the Gmail All Mail folder using your email client:

Apple Mail:

  1. Open your email client. (For this example I'll use Apple Mail)
  2. Configure your email client as recommended in Gmail Help: ... swer=78892#
    • Be sure that you configure Mail > Preferences > Accounts > Mailbox behaviors > Trash > [Gmail]/Trash
    • Open Window > Activity - so you can view the progress of the email move operations
    • Backup your email messages to a folder on your local computer using your email client. (I recommend creating yearly archive folders for your incoming and outgoing email messages as follows):
      • On My Mac (Local Folders)
        • ARCHIVE
          • IN
            • 2008
            • 2009
          • OUT
            • 2008
            • 2009
    • Move your email messages (500 - 1000 at a time) from your Inbox and Sent folders to the corresponding folders in your email archive. (Watch the Mail Activity window and wait until the move operation completes before moving the next set of emails or proceeding to the next step)
    • Verify that you have backed up all your email messages locally as described in the previous step and that the Mail Activity window indicates that there is no longer any email activity, then quit Apple Mail and restart the application.
    • Synchronize your gmail account with Apple Mail (Mailbox > Synchronize "Google")
    • Quit Apple Mail and restart the application.
    • Now that you have backed up all your email messages and synchronized your email account, you can start deleting email messages from the Gmail All Mail folder.
    • Click on the [Gmail] / All Mail folder in Apple Mail.
    • Move your oldest email messages, 500 - 1000 at a time, from "[Gmail] Gmail / All Mail" to the "[Gmail] / Trash" folder.
      (Watch the Mail Activity window and wait until the move operation completes before moving the next set of emails or proceeding to the next step. It is recommended that you move and delete less than 5000 emails per day.)
    • Synchronize your gmail account with Apple Mail (Mailbox > Synchronize "Google")
    • Verify that the Mail Activity window indicates that there is no longer any email activity, then quit Apple Mail and restart the application.
    • Login to the SJSU Gmail web interface and click on Trash.
    • Click the Empty Trash now link. Click OK to confirm.
    • Click on All Mail then click Oldest to verify that the email messages have been deleted from All Mail.

Using SJSU Google Services on Apple Operating Systems

Use multiple Google accounts simultaneously with browser profiles and containers

Both Google Chrome and Mozilla Firefox provide features that allow you to use multiple Gmail accounts at the same time, but keep them separate. This is helpful if you want to use some websites while signed into your SJSU Gmail account and others signed in with your personal account or an account from another facility, and avoid confusion about which is which.


Google Chrome lets you sign into multiple Google accounts each with its own window. Each profile will be completely separate, with its own bookmarks, browsing history, browser add-ons, and stored passwords. This is useful for keeping your personal information and bookmarks separate from your work/school accounts, as well as keeping multiple work/school accounts separate from each other.

  1. Open Chrome and click your profile icon in the top right.

  2. At the bottom of the menu that appears, click + Add.
  3. A new window will appear. Sign in with the Google account that you wish to add. 
    • NOTE: If you are signing into an SJSU account, you will be redirected to a webpage to login with your SJSU ID and authenticate with Duo.
  4. Now that you have added a second profile, when you launch Chrome you will be presented with a window showing all of your profiles and letting you choose which one you want to launch
