 Email Communication Services allows you to configure email with two types of domains: **Azure Managed Domains** and **Custom Domains**. 
 
 ### Azure Managed Domains
-Getting Azure manged Domains is one click setup. You can add a free Azure Subdomain to your email communication resource and you'll able to send emails using mail from domains like [email protected]. Your Azure Managed domain will be pre-configured with required sender authentication support.

 ### Custom Domains
 In this option you're  adding a domain that you already own. You have to add your domain and verify the ownership to send email and then configure for required authentication support. 
 
 ### Sender authentication for domains
 Email authentication (also known as email validation) is a group of standards that tries to stop spoofing (email messages from forged senders). Our email pipeline uses these standards to verify the emails that are sent. Trust in email begins with Authentication and Azure communication Services Email helps senders to properly configure the following email authentication protocols to set proper authentication for the emails.
 
 **SPF (Sender Policy Framework)**
-SPF [RFC 7208](https://tools.ietf.org/html/rfc7208) is a mechanism that allows domain owners to publish and maintain, via a standard DNS TXT record, a list of systems authorized to send email on their behalf. Azure Commuication Services allows you to configure the required SPF record that needs to be added to your DNS to verify your custom domains.

 **DKIM (Domain Keys Identified Mail)**
-DKIM [RFC 6376](https://tools.ietf.org/html/rfc6376) allows an organization to claim responsibility for transmitting a message in a way that can be validated by the recipient. Azure Commuication Services allows you to configure the required DKIM records that need to be added to your DNS to verify your custom domains.
