What you need to know about whitelisting email addresses

Whitelisting an email address is the process of telling your email provider that a specific email address is "safe".

Many companies today have robust back-end restrictions on their email hosting which is designed to reduce spam and phishing emails from coming in to business emails. These restrictions generally include "generic" email addresses, things like noreply@ and notifications@.

When you get HubSpot, you want to work with your IT team to make changes to your whitelist/allowlist/safe sender list.
