A user-defined email message interaction occurs when you manually start the send, while a triggered message interaction occurs in response to an action or API call. When you define an email message interaction, specify the name, external key, and description of the message interaction to identify and describe the message in the application and in API calls. The email message interaction allows you to specify whether to send the message in Multi-part MIME format. ## Send Classifications Send classifications allow users to save the details of an email send and use them for multiple sends. Create a send classification before including it in the interaction. Then, specify the send classification to use when you create an email message interaction. You can override the sender profile and the delivery profile for the send classification that you choose. ## Send Logging If you use data extensions, you can enable send logging when you create the email message interaction. Send logging captures email variable values for each send in a data extension. That data extension retains this data for a specific for a specified definition. In addition to selecting Send Logging in the interaction, create a send logging data extension and update the data extension with AMPscript in the email message content. ## Audience Indicate the audience that receives your message when you create an email message interaction: - Any number of lists or groups. An audience that contains lists and groups cannot contain data extensions, filters, or Salesforce items. - Exactly one data extension - Exactly one filter - Any number of Salesforce reports or Salesforce campaigns, if you integrate your account with another Salesforce Cloud. Select subscribers to exclude from the audience. If your audience contains lists, groups, data extensions, or filters, your exclusion can contain any number of lists, groups, and data extensions. The exclusion can also include a domain exclusion list, which is a data extension that contains a list of email domains. By selecting your domain exclusion list, the system excludes any email addresses that use that domain. If your audience contains Salesforce reports or campaigns, then your exclusions can contain only Salesforce reports or campaigns. You can exclude subscribers using a script. Create criteria to exclude subscribers in your audience who meet that criteria from the send. Triggered email interactions and user-initiated email message interactions sent to data extensions use the List Detective feature to prevent sending to email addresses that can damage your deliverability. You can choose to deduplicate the send by email address. If you select this option, the message interaction sends only one email to an email address, regardless of how many times that address appears in your audience. If you do not select this option, the interaction sends to all email addresses in the audience, even if they appear more than once. ## Test Audience Use the same tools available in the Audience section in the Test Audience section. The test audience includes the test list that receives the message when you click Test Send. This feature lets you test message interactions without editing them. ## Message Properties Specify CC email addresses and BCC email addresses for the email. - Email addresses you enter as CC email addresses are visible to all recipients of the email. - Email addresses that you enter as BCC email addresses are invisible to recipients of the email. ## User Tracking When you create the email message interaction, decide whether to track the email links and whether to suppress the send from reports. ## Create a User-Initiated Email Interaction In Email Studio, create a user-initiated email message interaction to send to a user-initiated subscriber list or data extension. Before you begin, create the email message content and the send classification first. 1. Click **Interactions**. 2. Click **User-Initiated Emails**. 3. Click **Create**. 4. Complete **Properties**.
