Please refer to article 5.2 Creating an email campaign for how to create campaigns and a detailed description of all features.
Similar to email campaigns, campaigns can be started from the orders page, the candidate page or from the campaign menu (see link above).
Switch to Communication channel "SMS":
Due to the limitations of SMS, its is not possible to change the text format or attach the opportunities in the SMS itself. But you have the same options to choose what opportunities to include and what information to share.
The action button is replaced with a link in the SMS and you can choose between the similar behavior as in the emails described in 5.2 Creating an email campaign.
Change the text of the SMS how you like and add the opportunities (also possible to turn opportunities off if you don't want to include them).
Preview the SMS before adding recipients.
Add the candidates you would like to send the SMS campaign to by navigating to recipients and click "+ Add candidates". Filter and add the candidates you like.
Click "Launch Campaign" if you are ready to send it immediately or "Save draft" to send it later.
Following up on the campaign is done similar to the email as described in 5.4 Following up on campaign results
