Microsoft Flows - Send an Email - SPUtility

Before we go into how to implement it, we shall quickly look into the advantages and disadvantages of using this approach to send emails In Flows for Sharepoint.

Advantages:

• Using this approach we can avoid the complex configuration to send  Email to Sharepoint Group 
• we can set any Sharepoint user in From Address, i.e. the Email can be addressed from any existing Sharepoint User. This will be helpful to send emails on behalf of Managers etc.
• Can send HTML formatted email content. This helps us to design custom templates

Disadvantages:

• Cannot attach files in the email
• Can't send emails to external emails or mail boxes, i.e. the emails that doesn't have user accounts
• From Address cannot be configured to any Mailbox or random name

Implementation:

we use SPUtility SendEMail Rest API method to send an email using HTTP Request to Sharepoint Action

As the SPUtility send email is a sharepoint related method, it only accepts Sharepoint entities to send emails and also if we provide a Sharepoint Group name, it would resolve it internally and sends emails to group members.

Below is sample screenshot and the JSON input we used to send email.

This email goes to Sharepoint Group "Demo Sharepoint Group", CCing Sharepoint group "CC Sharepoint Group" along with user "John". And this email is sent on behalf of "Riyana"

Also, we provided an external email id in TO list, but it doesn't send. 

Body:

 {  
       'properties': {  
         '__metadata': {  
           'type': 'SP.Utilities.EmailProperties'  
         },  
         'From': 'riyana@tmsdemo.onmicrosoft.com',  
         'To': {  
           'results': ['Demo Sharepoint Group','nonuseremail@external.com']  
         },  
         'CC': {  
           'results': ['CC Sharepoint Group','john@tmsdemo.onmicrosoft.com']  
         },  
         'Body': '<p>Demo EMail, <br/><br/>Sample email through Flows.</p>',  
         'Subject': 'Sample email through SPUtility'  
       }  
     }  

And the email in Outlook is
