Create a new email in Outlook and add recipients as usual - note you can also pull in recipient emails and assistant emails using your email template, example below. Open the Cirrus Sidebar by clicking the three dots on the far right of the tool menu at the bottom of your message and choosing the options shown below. It may take a few moments to load.

Click the template icon at the top of the sidebar

Navigate to the folder (1) with the email template you need or use the search bar (2) or click "New Template" (3) to create a new template. Click the preview icon (4) to get a quick view of the template, click the "Edit" button (5) to make changes to the template or click on the template name (6) to select the template for use.

If the template is a Lightning Template or  was created in the Cirrus Plug-in, you can make any final edits to your template at this point. Once you're satisfied, click "Save & Merge".

Choose the correct records for each merge field (in this example, it's just the contact record but you may have templates that are more complicated and include other records as well), then click "Merge".

Review the email, including the subject line, attachments and the CC/BCC lines. You can make additional changes or personalizations directly in the body of the email. The email will send to all recipients upon clicking "Send".
