Setting Titan as Your Default Email Application

When you click an email address on a website, a contact page, or in someone's email signature, it usually opens as a "mailto" link — a shortcut that starts a new email in whichever app is set as your default. If that app isn't Titan, the link might open somewhere you don't use, or not open at all.

Setting Titan as your default email app means every mailto link opens directly in Titan Webmail, with the recipient, subject, and message already filled in. This guide shows you how to turn this on, and what to do if the setup doesn't stick the first time.

Set up Titan as your default email app

1. Go to Titan Webmail and log in with your Titan email account.
2. In the top-right corner, click the Settings icon. 
   
    
3. In the Settings menu, select Set Titan as the default email app. 
   
    
4. In the dialog that appears, click Set as default. You'll then see a permission prompt from your browser, asking whether to let Titan handle email links.

5. In the browser's permission prompt, click Allow. Once you click Allow, Titan becomes your default email app for mailto links in this browser.

If another email provider was previously set as your default, Titan replaces it automatically once you grant permission. In some browsers this replacement doesn't happen right away — if that's the case for you, follow the steps in Fix setup issues by browser below.
 

Fix setup issues by browser

Use these steps if any of the following happened during setup:

• You didn't see a permission prompt at all.
• You clicked Block or closed the prompt by mistake instead of clicking Allow.
• You want to redo the setup because another app took over as default again.

Because the prompt only appears once per browser, you won't automatically see it again after your first attempt — these steps let you reset it manually.
 

Chrome

1. Open Titan Webmail in Chrome and repeat the steps in Set up Titan as your default email app.
2. If no prompt appears, type chrome://settings/handlers into Chrome's address bar and press Enter.
3. On the Handlers settings page, turn on Sites can ask to handle protocols.
4. Under the Email section, if another handler (such as Gmail) is listed, click the three-dot menu next to it and select Remove.
5. Go back to Titan Webmail, refresh the page, and repeat the setup steps. 
   

Edge

1. Open Titan Webmail in Edge and repeat the steps in Set up Titan as your default email app.
2. If no prompt appears, type edge://settings/content/handlers into Edge's address bar and press Enter.
3. On the Handlers settings page, turn on Allow sites to ask to become default handlers for protocols.
4. Under Email, remove any existing handler, such as Gmail.
5. Go back to Titan Webmail and repeat the setup steps. 
   

Firefox

1. Open Titan Webmail in Firefox and repeat the steps in Set up Titan as your default email app.
2. If no prompt appears, open Firefox's Settings.
3. In the left menu, select the General section.
4. Scroll down to the Applications list.
5. In the Content Type column, find mailto.
6. In the Action column next to it, select Use app.titan.email.
   

What happens once Titan is your default

Once setup is complete, clicking any mailto link — for example, an address like email@help.com on a website — does the following:

• Opens a new browser tab (or switches to an existing Titan tab if you already have one open)
• Launches the Titan email composer
• Automatically fills in the recipient, subject, and message body based on the details in the link

This is what tells you the setup worked: mailto links now go straight to a ready-to-send Titan email, instead of opening another app or nothing at all.
 

Troubleshooting

Problem: Mailto links open in a different browser than the one you set up Titan in. 
Cause: The permission prompt only controls email links inside the browser you used for setup. If that browser isn't your computer's default browser, your device sends mailto links to the default browser instead. 
Fix: Either change your computer's default browser to match the one you used for setup, or open Titan Webmail in your default browser and repeat the setup there.

Problem: Titan stopped being your default email app after you set it up. 
Cause: You likely closed the permission prompt using the X button instead of clicking Allow. This blocks Titan from being the default. 
Fix: Repeat the steps in Set up Titan as your default email app and make sure to click Allow when the prompt appears.

Problem: Mailto links open your previous email app instead of Titan. 
Cause: You clicked Block in the permission prompt during setup, which tells your browser to keep sending mailto links to whichever app opened them last. Fix: Follow the steps for your browser in
