Specify test sample percentage

The test sample percentage specifies the percentage of subscribers from the mailing list, whom the A and B campaigns will be send to. For example, a test sample percentage of 20 specifies that the A campaign will be sent to 10% of the subscribers, B campaign will be sent to another 10% of the subscribers, and the winner campaign will be sent to the remaining 80% of the subscribers, after the testing ends.

To specify the test sample percentage, use the TestSamplePercentage property of the ABCampaign object. The following code sets the test sample percentage, while creating an AB campaign: ```C# using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using Telerik.Sitefinity.Modules.Newsletters;

namespace Telerik.Sitefinity.Documentation.CodeSnippets.DevGuide.SitefinityEssentials.Modules.EmailCampaigns.ABCampaigns { public partial class EmailCampaignsSnippets { public void CreateABCampaignTestSamplePercentage(Guid id) { NewslettersManager manager = NewslettersManager.GetManager(); var abCampaign = manager.GetABCampaigns().Where(c => c.Id == id).SingleOrDefault();

        if (abCampaign == null)
        {
            abCampaign = manager.CreateABCampaign();

            abCampaign.TestingSamplePercentage = 20;

            manager.SaveChanges();
        }
    }
}

}
