aws ses receipt rules for routing email to an existing email address

I have a domain registered with amazon route 53 (imagine example.com), and a workmail email based on that domain (imagine hello@example.com). I'm trying to create extra email addresses for this domain (imagine support@example.com and info@example.com). I came across this article which explains that the way to do this is by using SES' receipt rules. In SES my domain (example.com) is verified and has the appropriate SES MX record, and I've added the workmail email (hello@example.com) as a verified email address. I've followed the steps to create the receipt rule, specify support@example.com and info@example.com as the receipt conditions, create the sns topic, and I've successfully subscribed hello@example.com to the sns topic. However, when I send emails to support@example.com and info@example.com, nothing arrives in my workmail mailbox. What else do I need to do? How can I debug this?
