You can manage your Campaigns under the Campaign Manager on the BatchLeads site. Access the Campaign Manager by clicking the Campaign icon on the left navigation menu:
Click on the dots to the left of a campaign to access the action menu for that campaign. From here you can select to View, Edit, Remove as Completed, Archive, or Import Contacts.
Viewing an existing campaign allows you to see the details associated with that campaign, such as the Status, which is the number of contacts and the progress in contacting them (expressed as a percentage at the top of the page).
To change the SMS Template you are using for a campaign, use the dropdown on the left side of the page to select the SMS template you'd like to use.
Note the Daily Send Limit documented below.
To Continue with the Campaign, you would send additional Messages using the Send button under the message preview window at the top of the screen.
You can Import Contacts from this page, by clicking the Import Contacts button near the bottom of the page. This allows adding contacts to this specific campaign through import.
