# Create a Campaign Message
* Log in to your CrossEngage account.
* Go to “Campaigns” and click “Create Campaign” in the top right corner of the page.
* Choose whether you want to create an Audience or a Realtime campaign. Information about the distinction between these types of campaigns found [here](/data-and-engagement-platform/campaign-management/campaigns.md).
* Once you have created your campaign and filled in the “Campaign setup” and “Target group” sections, go to the `Messages` section and click `Create new message`.
* Select `SMS` from the dropdown menu. The message setup screen will open.
#### Message setup
**Sender info**
* Enter the sender’s information in the sender field. This field accepts alphanumeric values and may contain handlebars. It can either be a telephone number in an international format, for example, “+49 1234 56789”, or an alphanumeric string such as “companyName”.
**Message text**
* Enter the SMS text you would like to send in the message text block. You can use handlebars to personalize the messages – learn more about handlebars [here](/data-and-engagement-platform/messages/personalization.md).

LINKMobility charges extra for long messages. For example, a long message split into 3 parts will be charged at 3 times the rate of a single message.
You will have to pass the opt-out / in data via our API for opt-out management when using LINKMobility.
