How to Send a Postcards Email Template with Outlook 365
Important Update! We're introducing a new feature that allows you to send your email templates from Postcards directly to Outlook 365 on both Mac and Windows.
We have released new email templates for Outlook.
Check out the video below for a detailed walkthrough.

Additionally, you can use our Outlook add-in to insert HTML email templates into Outlook.

Steps
1. Create and export a Postcards template
The main thing we need is a Postcards template for the HTML code.
In the Postcards app, create a template. Mine looks like this:

Next, export your template so you can access the generated HTML code.
In the top right corner of the app, click Export → Download as ZIP. Before downloading, make sure the Host images online option is enabled. This ensures your images are properly hosted and will display correctly when the email is sent. Your screen should look like this:

Press “Download Zip” and extract the file into a folder. My folder looks like this:

If you open this file in your browser, you should see the Postcards template you just created.
Now, we have everything we need to add this template to an Outlook 365 email.
2. Give Outlook 365 the ability to send HTML email
In the top left corner of Outlook 365, click “New Email” to compose a new email.

In the new window that opens, right-click on the toolbar and select “Customize this Ribbon”:

In the window that appears, make sure that on the right menu, “New Mail Message” is selected. Click the “New Group” button in the bottom-right.

With this “New Group (Custom)” item selected, click “Rename” and then rename it to “HTML Email”. Then click “OK”.

With your HTML Group selected on the right, click “Attach File” in the menu to the left. If you don’t see “Attach File”, make sure that the “Choose commands from” select box on the upper-left is set to “Popular Commands”.
Then click the “Add >>” button which appears between the two menus.

The menu on the right should now have an “Attach File” command attached and should look like this:

Click “OK” to save your changes.
3. Inserting the Postcards Template
Now, in your draft, you will see a new item on your toolbar called “Attach File” with “HTML Email” underneath it. Click it.

Select the index.html file you exported in Step 1. In the bottom-right corner of the window, click the small arrow next to Insert, then choose Insert as Text.
This ensures the raw HTML code is inserted properly instead of being added as a regular file attachment.

Your message should now display the full HTML version of your Postcards template directly inside the email body, similar to the example below.

Now you should have the Postcards template in an Outlook 365 email!
You can send yourself a test email to see if the template sends as you expect.
This process will set up HTML email for future use. The next time you want to send a Postcards email template with Outlook 365, you can skip the second step.
