After setting up your filter or rule, verify that forwarding is working correctly:

1. Wait for your next Interac e-Transfer, or send yourself a small test transfer from another account
2. Check your Biller dashboard -- the payment should appear within a few minutes
3. You will also receive a confirmation email from Biller summarizing the recorded payment

If the payment does not appear, check that your filter is active and that the forwarding address is correct. You can also use the built-in test feature to confirm your setup -- see Send a test email for instructions.
