Choose how strictly Aster blocks trackers, remote images, and link tags, and hide your address with ghost aliases.

Opening a message can tell the sender when you read it, your IP address, and your device type. Aster blocks the common ways this happens by default. Remote images, fonts, stylesheets, and tracking pixels stay blocked until you change these settings.

Load blocked content in one message

When a message contains blocked content, a banner at the top reads External content blocked, followed by what was blocked, such as images or tracking pixels.

• To load the content in that message, select Load in the banner.
• To see each blocked item, open the banner’s details.

Loading content tells the sender what the blocked content would have told them, so load it only for senders you trust.

Change what Aster blocks

1. Go to Settings > Security.
2. In Tracking Protection, turn Enable Tracking Protection on or off. While it’s on, you can also turn Block Spy Pixels on or off. A spy pixel is an invisible image whose only job is to report that you opened a message.
3. In Images, set Block Remote Images, and then choose a Remote Image Loading option: Never load, Ask before loading, or Always load.
4. To stop messages from loading fonts and stylesheets from outside servers, turn on Block Remote Fonts and Block Remote CSS.

Remove tracking tags from links

Marketing mail often adds tags to its links, such as utm_source, that tell the sender which campaign you came from.

1. Go to Settings > Security.
2. In Tracking Protection, turn on Enable Tracking Protection. Clean Tracking Links then shows Active. It has no switch of its own and follows Enable Tracking Protection.

Aster removes known tracking tags, and the link still opens the same page. The site can still see that you visited it.

To see a warning before a link takes you outside Aster, turn on External Link Warnings. To check where a link goes before you open it, hover over it, or touch and hold it on a phone.

Remove location data from photos you send

Photos from phones and cameras can include GPS coordinates, the device model, and the time the photo was taken.

1. Go to Settings > Security.
2. In Images, turn on Strip Image Metadata.

Aster then removes this data from images before they’re sent. This setting is on by default.

Show mail as plain text

To show incoming mail as plain text, go to Settings > Security, and in HTML Content, turn on Block HTML Rendering. Plain text prevents tracking and visual tricks, but messages lose their formatting.

Send from a ghost alias

A ghost alias is a temporary address that hides your real one. Use it for one-time sign-ups or anywhere you don’t want to share a permanent address.

1. In the composer, open the sender menu next to the from address.
2. Under Ghost, select Create Ghost Alias, or choose a ghost alias you already have.
3. Write and send your message. Aster sends it from the ghost alias instead of your real address.

Your plan sets how many ghost aliases you can create each month.

Manage ghost aliases

1. Go to Settings > Aliases, and then select the Ghost Aliases tab. Each alias shows when it expires.
2. Choose what to do:
   • To keep an alias longer, select Extend. A ghost alias can last up to 90 days.
   • To retire an alias, select Expire. A new ghost alias stays live for 30 days before you can expire it, unless you’re on Supernova or Family.

An expired ghost alias can’t be recovered, so expire one only when you no longer need replies to it. For permanent addresses, see Add aliases and custom domains.

Turn on Aster Vanguard

Aster Vanguard adds protections for journalists, activists, and other people at higher risk. It requires Nova, Supernova, Duo, or a Family plan, and it includes three protections:

• PIN App Lock asks for a PIN or passphrase before Aster Mail opens on that browser or device.
• Duress PIN is a second PIN that, when you enter it on the lock screen, erases the Aster data stored on that device and signs you out. It appears after you turn on PIN App Lock.
• Lockdown Mode blocks all remote content with no exceptions, hides sender and content in notifications, turns off real-time sync, and asks before opening any external link.

To turn on Vanguard:

1. Go to Settings > Security.
2. In Aster Vanguard, turn on Enable Vanguard.

To turn Vanguard off, turn off Lockdown Mode first. For every Vanguard option, see Aster Vanguard and Lockdown Mode.

Troubleshooting

• Images in a trusted message don’t appear: Select Load in the banner, or change Remote Image Loading.
• You don’t see link warnings: Make sure External Link Warnings is on in Settings > Security.
• You can’t create a ghost alias: You might have used all your ghost aliases for the month. Wait for the monthly reset, or upgrade your plan.
