The rule suppresses sendout for the recipients who match the rule criteria. > [!NOTE] > This personalization rule always suppresses the sendout of the entire message to the specified recipients, even if you insert it in only one text field or one CMS paragraph. --- ## Procedure 1. Open the message, template, or group where you want to insert the rule. 2. Select any text field where you want to place the rule. 3. Define a personalization rule that identifies the recipients based on their attributes. 4. If you are adding the rule to a message, insert it anywhere within the message text (see *Insert a personalization*). 5. If you are adding the rule to a group, copy the code from the personalization wizard and paste it under the **Sendout Options** tab in the message header or footer. 6. Inside the personalization tags, insert the command `<ec:skiprecipient/>`. The personalization can also be integrated into a CMS template. --- ## Example You want to prevent non-German-speaking recipients from receiving messages created with a German-language CMS template. Each German-speaking recipient has the value “German” in the `Language` attribute. Use the following rule: ```plaintext <%InsertIf expression="${((user.CustomAttribute['language']!='german'))}" id="NonGerman"%> <%/InsertIf%> ``` ## Related - [Creating a Personalization Rule](/create-a-personalization-rule.md)
