# Email in Flex for administrators

> \[!WARNING]
>
> Email in Twilio Flex is not a HIPAA Eligible Service and should not be used in workflows that are subject to HIPAA.

## How email works

Flex relies on Twilio SendGrid for sending and receiving email. When you set up email as a channel in Flex, Twilio automatically sets up a SendGrid account for you.

## Email quota

Your Flex account may include a quota for the maximum number of emails that you can send. The quota applies to Named User and Active User Hours pricing models. If you go over your quota, your account will be charged per additional email.
