To upload new email templates, you can follow these steps:
Login to your Mailchimp account.
Go to the templates section and click on "Add Template".
You can either choose a pre-designed template or create a new one from scratch.
Customize the template by adding and amending the content, layout, and design.
Once you are satisfied with the changes, save the template on the Mailchimp site.
After saving the template on Mailchimp, it will automatically appear in Smartr365. This means you can easily access and use the new template when creating email campaigns or sending out emails through Smartr365.
