Your forwarding address

Your forwarding address is a unique email address in the format:

For example, your address might look like k7xm9p@income.biller.ca or r4tn2w@income.biller.ca. Each user gets a different, randomly generated address.

When Biller receives an email at your address, it checks that the email is a valid Interac e-Transfer notification, extracts the payment details, and adds them to your income tracker. Any emails that are not Interac e-Transfer notifications are safely ignored.

You can find your forwarding address in two places:

• During onboarding -- your address is displayed on the setup screen right after you create your account, with a button to copy it to your clipboard
• Settings > Profile -- your address is always visible on your profile page, where you can copy it at any time

Your forwarding address never changes unless you explicitly request a reset, so you only need to set up forwarding once.

Your forwarding address uses a randomly generated token as the local part (the portion before the @). This token is:

• Unique to your account -- no two users share the same address
• Randomly generated -- it is not based on your name, email, or any personal information
• Unguessable -- the token is long enough that it cannot be guessed by trial and error

This design means that someone cannot send emails to your Biller account unless they know your exact forwarding address. It acts as a shared secret between you and Biller.

Your forwarding address should be treated like a password. Here is why:

• Anyone who knows your address can send emails to your account -- while Biller only processes valid Interac e-Transfer notifications (and verifies DKIM authentication), sharing your address unnecessarily increases your exposure
• Do not post it publicly -- never share your forwarding address on social media, forums, or public websites
• Only use it in your email provider's forwarding settings -- the only place your address needs to be entered is in your Gmail filter, Outlook rule, or equivalent auto-forwarding setup

If you believe your forwarding address has been compromised, you can request a new one from Settings > Profile. This will invalidate the old address immediately, and you will need to update your email forwarding rules with the new address.
