You can send your emails created in the Postcards app directly to your HubSpot account.
Connect your HubSpot account
Click the “Export” button and choose the “Export to” option.
In the pop-up, choose HubSpot to connect your account.
In the next step, choose your account and click on it.
With the first connection, your template will be exported to your HubSpot account. Click the link “HubSpot Templates” to see the assets in HubSpot.
Next, click the exported templates and you will see the HTML code of this template. You can preview it to check if it’s the same as you created using the Postcards app.
Next time you need to export the email template, you can click the already connected account and Postcards will export the template directly to your HubSpot account.
