Each newsletter campaign has a target audience. This target defines the contacts who will receive the newsletters of this campaign.
Where to manage the targets?
To add a filter to your target go to "Campaigns" and choose your campaign from the list. Then click on the "Target" section.
Under the Filters section, select a filter in the drop-down list and click on "Add".
For example: if you have two filters, Donors and Members, by creating a campaign targeting these two filters, all contacts that are Active Members AND/OR Donors will be selected.
Note that if you want to join a combination of two filters, for example, only Donors and Active Members, you need to create a complex filter.
In addition, a contact in more than one filter will only receive the newsletter once, even if they are selected by more than one filter.
If you want to create a campaign that targets all your contacts, use the All contacts filter that is present by default.
