Create a Disposable Email Address: The What, Why and How-to


Creating a disposable email address is an effective way to protect your inbox from spam, unwanted newsletters, and potential privacy risks. This “how-to” blog post will walk you through the what, why, and how of disposable emails, plus detailed steps for setting them up on Gmail, Outlook, Yahoo Mail, and Apple Mail.


What Is a Disposable Email Address?

A disposable email address is a temporary or secondary email that you use for sign-ups, promotions, or online services, ensuring your main address stays private and spam-free. These addresses forward mail to your main inbox or may expire or be deleted after use, safeguarding your privacy and decluttering your email.​


Why Use a Disposable Email Address?

  • Spam Protection: Avoid unwanted marketing emails and spam after registering on unfamiliar sites.
  • Privacy: Keep your personal or professional inbox private when submitting email addresses online.
  • Organization: Route newsletters, trial subscriptions, or one-off contacts into separate folders for easier inbox management.

How to Create Disposable Email Addresses on Major Platforms

Gmail

Gmail offers two easy disposable email solutions:

  • + Aliases:
    • Add a +keyword after your username when signing up (e.g., yourname+promo@gmail.com).
    • All mail to that address arrives in your regular inbox. Use Gmail filters to auto-label, sort, or delete such messages.​
  • Send As Alias:
    • Go to Settings > Accounts and Import > Send mail as > Add another email address, and follow the steps to create a new alias linked to your account.​
  • Pro Tip:
    • Set up filters in Gmail to automatically manage or remove emails sent to specific aliases.​

Outlook

With Outlook.com, you can create and manage aliases easily:

  • Add Alias:
    • Log in to Outlook.com and visit Account Settings > Your Info > Manage how you sign in to Microsoft.
    • Click "Add email" and create a new Outlook.com alias.
    • Send/receive using this alias, and manage or remove it whenever you’d like.​
  • Use for Different Purposes:
    • Register the alias for newsletters or new websites to keep your main inbox spam-free.

Yahoo Mail

Yahoo Mail allows disposable addresses tied to a base name:

  • Create a Disposable Address:
    • In Yahoo Mail, click the Settings gear > More Settings > Mailboxes.
    • Under Disposable email address, click Add.
    • Set a base name (nickname) and create up to 500 unique variants (e.g., nickname-shopping@yahoo.com) for various sign-ups.​
  • Manage or Delete:
    • Disable or delete disposable addresses as needed to cut off unwanted senders.​

Apple Mail (Hide My Email & iCloud+)

Apple’s Hide My Email (with iCloud+) provides powerful disposable email options:

  • Via Hide My Email:
    • On iPhone, iPad, or Mac (macOS 12, iOS/iPadOS 15+), go to Settings > [your name] > iCloud > Hide My Email.
    • Click or tap “Create New Address” to instantly generate a random, unique email address that forwards to your real inbox.
    • Use this address anywhere online, and Apple will protect your real email and identity.
    • You can label or deactivate any forwarding address at any time.​
  • Safari/Web Forms:
    • When prompted for an email in Safari or some third-party apps, you can choose Hide My Email directly in the form field.​
  • iCloud + Rule-Based Filtering:
    • You can also use the + alias in your iCloud address (e.g., yourname+event@icloud.com), then set up rules in iCloud.com Mail to sort or discard emails to these addresses.​

Other Disposable Email Tools

  • External Services:
    • There are many third-party tools (like Temp-Mail, Guerrilla Mail, and Mailinator), offering instant, no-registration email addresses for one-time use. These are helpful for fast, anonymous sign-ups, but generally are not intended for messages you’ll want to keep long-term.​
  • App Store Apps:
    • Apps such as Temp Mail for Apple devices provide additional throwaway email solutions right from your phone.​

When Should You Use a Disposable Email Address?

  • Signing up for new websites, free trials, or online contests where you don’t trust the sender
  • Downloading eBooks, whitepapers, or free resources in exchange for an email address
  • Testing new services or apps with minimal risk to your inbox
