What Are Email Alias Suggestions in Gmail?

Email alias suggestions appear when Gmail auto-completes email addresses to whom previously you have sent messages or that are connected to your Google Account. 

  • The suggestions could be secondary email addresses associated with your account
  • Delegated or shared inbox aliases, such as team or group email addresses you’ve been given access to like [email protected].
  • Outdated or deprecated email addresses that are no longer in active use but still stored in your history.
  • Other users’ aliases within your organization, especially if contact sharing is enabled in your Google Workspace domain.

How to Stop Email Alias Suggestions For Individual Users

  1. Remove Autocomplete Suggestions Manually
    (Tip: This only works for suggestions from your past contacts or history, not aliases defined by your administrator.)
    If Gmail keeps suggesting an unwanted alias or contact you can follow the below steps.
    • Start composing an email.
    • Begin typing the email address or alias.
    • Hover over the unwanted suggestion and click the X (Remove) button.
    • Gmail will no longer auto-suggest that address.
  2. Manage Your Send Mail As Aliases
    (Note: You can only remove aliases that you have personally added and not those managed by your admin.)
    To stop Gmail from showing certain From addresses follow the steps below -
    • Open Gmail.
    • Click the settings > See all settings.
    • Go to the Accounts tab.
    • Under Send mail as, click delete next to the alias you no longer want to use.
      stop Gmail from showing certain From addresses
  3. Clear Your Gmail Search History
    Sometimes Gmail pulls suggestions from prior searches and message recipients.

    To clear Gmail’s stored data do as follows -
    • Visit your Google My Activity: https://myactivity.google.com/
    • Filter by Gmail and delete past activity.

    Tip: This prevents Gmail from suggesting the alias domain-wide.

    • Navigate to Users.
    • Click the user’s name.
    • Under User information, select Email aliases.
    • Remove or edit the alias accordingly.
