Features & Capabilities

Maskmail is a free email privacy tool that gives users the ability to instantly create anonymous masked emails, so you don’t need to share your private email address when signing up to a new service. It’s a simple and convenient way to protect your online privacy.

Maskmail is a simple but powerful service that was designed with the sole purpose to protect your online privacy. Maskmail instantly generates anonymous masked emails for every service you sign up to, making it very difficult for advertisers to track you online and offline. Since every email created with Maskmail is unique it also is an effective way to protect your inbox from unwanted emails.

Maskmail is available for your desktop, using our Chrome and Firefox browser extensions and will soon also become available for your mobile (our Maskmail iOS & Android app will be released shortly).

In general, we recommend using Maskmail for all your sign-ups, especially in instances when you want quick one-time access for a new service; if you're worried a site might spam you later; or if you're just not sure a company is trustworthy.

You can easily manage your masked emails by accessing your Maskmail Dashboard via the Maskmail website, or via the web browser extension. The Dashboard makes it easy for you to block or delete any email instantly, making any ‘cancellation’ or ‘unsubscribe’ immediate and painless.

Is Maskmail Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Maskmail requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

  • Low ******* ****** ** *** ********* ******** ************* ********** ************* ***********
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Maskmail is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
