Step 2: Add mailing status to the groups

To send a letter to the groups, you don't need a mailing status. You can send letters based on event, balance, way of payment etc. To prevent extra work, please check first if you do need mailing statuses.
You can check the filter options on this page.

There are 2 ways to add that mailing status to a group.

You can either do that via the group module -> mailings -> Assign group mailing status

Select the group(s) that need a certain status, click the envelop icon in the top of the table and choose the mailing status the selected group(s) need.

Use the 'Checkbox selection tool' to 'Select From / To' and 'Deselect From / To' to allow you to quickly select or deselect a range of checkboxes. Click on one checkbox, then click on another, and both these checkboxes and all checkboxes in between will be selected or deselected.

'Select By ID' is only available when the table includes an ID column, and allows you to select your desired checkboxes by entering comma-separated IDs into the dialog.

You can also do it via the group list. Edit the group and in the bottom of the screen you can change the mailing status.
