Sending a beautifully formatted email from Power Automate (Flow)

updated March 10, 2020

I recently shared a winning use case for Office 365. Within this use case, I am using a flow in Power Automate to send beautifully formatted emails to our users. Something like:

Okay, maybe it’s not that beautiful, but it is colorful, has an image, and pops in comparison to black and white text only emails.

Using the Rich Text Editor in the Email Action

The Send Email actions include a rich text editor already, allows you to bold text, add some color, and format the email much like you can in Outlook.

That may suffice for your needs, but sometimes we need to send a fully formatted email, like my example above. That example wouldn’t be possible using the rich text editor approach. So let’s work around it and get this beautiful email sent!

Check out Outlook’s other sending email options here.

Power Automate sends formatted emails with ease

Inside the rich text editor, note the </> button. That button allows you to create exactly the email you want. Any HTML you want to put in there you can.

As long as you know HTML, you can send beautiful emails. DONE!

What if I don’t know HTML?

I know HTML but I didn’t want to write the HTML for this email. Call me lazy, or too busy, or just intuitive :D. Instead, here’s what I did, and what I suggest to you.

Create a new email in Outlook.

Style the email: add colors, content placeholders, images, tables, etc. For content placeholders, put something obvious like %%FULLNAME%%, %%LINK TO SOMETHING%%, %%MESSAGE%%, etc. Whatever data you expect the Flow to load for you. Something to make the text pop out to your eyes later on.

Email yourself the email.

Open the email you just sent to yourself in Outlook. Open it in a new window, not in the preview pane in your Inbox. Go to Message tab, then More Move Actions > Other Actions > View Source. It’s kind of hidden:

Don’t be scared! If you don’t know HTML, the resulting action of clicking above might have your eyes hurting. That’s OK!

You should see something like this:html source of email.png

Look for your content placeholders, I see mine, %%FULL NAME%%, right about halfway down. What’s all that other stuff on the page? HTML! Don’t worry about it.

NOTE make sure to start with <html and end with </html>. You may get other message header details in there, ignore that, just copy what’s between <html... </html>

Click the </> button in the rich text editor and paste in this content.

Now replace your content placeholders with dynamic values from Flow!

That’s it

Images are tricky

A quick note on images. Outlook takes the image you included in your email and converts it to a string, to plain text. I found copy/pasting this didn’t work in Flow. I think the text ends up being too long in this action and it breaks.

Instead, what you should do is upload the image to the cloud. I used our marketing system Pardot, but you could upload it to a Google Drive, OneDrive for Business, a blog site, anywhere. Get the anonymous visitor URL to the image itself, and swap that out for the image.

Look for <image src=”ab2md3m… in the HTML and change the value of the src property to the URL of the image. Your src should look like <image src=”https://url/to/your/image.png&#8221; />.

That’s it!

I hope this little trick works for you. Alternatively, you could find a WYSIWYG editor somewhere and format your email and then copy/paste that HTML as well. I find, that since the email was made in Outlook, its source is very Outlook friendly.

  1. This was amazing and beautiful. How do I clean up the brackets from the form field?

    MARKETING SOURCE: [“Sidewalk sign”]
    PREVIOUS CONTACT HISTORY: Nope, this is our first encounter.


  2. This worked great for me…I can see a beautiful logo in my flow generate email, however, others only see the alt text and box with a red x. I cannot find anything online to help me figure out why I can see it, but others cannot. Also how do I find the anonymous visitors URL?


    1. Where is the logo image stored? If it’s in SP, then the user would have to authenticate against SharePoint and then they can see it. Email client, like Outlook, won’t prompt for authentication.


  3. This is great!
    I used to make a better looking table in the email sent from flow.
    However, I have a problem that my auto-signature (which normally is in a table with no borders) also gets the style of the table, which I do not want.
    How can I end the style of the content that comes from flow, so my autosignature keeps its original style?

  4. This is a great tip. Previously I was creating Word templates, populating them, converting them to PDFs and then sending them via e-mail. This cuts out all those steps. Thanks so much!!!


    1. Yes! You can’t. ;)

      Emails cant use an authenticated source for images. Maybe if you did an anonymous link to OneDrive, that may work. I find I have to put the images into a public location like my blog or git. Sorry I wish there was a better story.


  5. This is an excellent and very helpful walk-through! I’m a bit unfamiliar with HTML, so the one thing I think would be great to know is how to get those image URLs if they are saved to your computer instead of finding them on the internet. Thanks so much!


    1. You won’t be able to get the image URLs until they’re saved on the internet somewhere. Can’t use them locally :(
      However, if you’re using DropBox or OneDrive, something similar, you can throw them up there and get the anonymous link to them, that _should_ work fine.


  6. How do you turn OFF html formatting inside the Flow editor? I turned it on, but now I can’t get back to the regular text editing tools?


  7. Everything worked great, except for inserting images. The instructions about changing the value of the src property to the URL of the image are not clear.


    1. I updated the text a little, but unsure what’s not clear about it. What part are you struggling with? If you’d like, you can email me at david.lozzi at and we can discuss further. Thanks!
