Generally, we reply to all emails within 1-2 days. If you're not receiving a response from Boost Collective support, or not receiving the 2-step authentication emails, it's likely that they're either going to spam, or being bounced entirely by your email provider. 

Check in with your email provider to ensure that all emails from and are allowed. If you're using an older email, such as a school email, etc., considering using something more permanent, like Gmail.
