Step 1: Click on the Mr.Delivery from the left side of the menu bar.

Step 2: Choose the tenants you want to send the email.

For example, if you want to send an email to all your active tenants use the filters as shown in the below image. 

Step 3: Choose the template that you would like to use using the "Template Category" and "Choose Template" drop down boxes. You then can preview the template you've selected before sending it out to your tenants, as shown below. 

(You can edit these templates, as well as make your own custom ones, in the Settings menu.)

Step 4: Choose the tenant(s) you'd like to send the email to by selecting the check box next to each name. You can also select the check box at the top of the list to select all of the tenants that fit the criteria you set.

Step 5: Click on the Send button to send the selected email to the tenants you selected.

With this, you've successfully sent your email to your tenants.
