To configure an automation to run as soon as a process completes on the company's website, especially when there is no access to SFTP, the best approach is to trigger the automation via API. Salesforce Marketing Cloud provides robust API capabilities that allow external systems to trigger automations directly. This method ensures the automation runs immediately after the web process completes, providing a seamless and efficient solution.

To execute complex campaigns with multiple messages in both Email and Mobile, marketers can use Automation Studio for querying and segmenting data from multiple data extensions. Journey Builder can then beutilized for orchestrating the messaging and flow control activities. This combination leverages the strengths of both tools to manage daily sends and complex campaign workflows. For detailed guidance, see theAutomation StudioandJourney Builderdocumentation.

To meet the requirement of sending a daily report of all subscribers emailed in the last 24 hours to the Enhanced FTP Export folder, the following activities should be configured in Automation Studio:
* SQL Query: To select the unique email addresses of subscribers emailed in the last 24 hours.
* Data Extract: To extract the data into a file format suitable for transfer.
* File Transfer: To move the extracted file to theEnhanced FTP Export folder.
This combination ensures that the data is queried, extracted, and then transferred as needed. Reference:

To improve email accessibility, increasing the font size to over 16pt is a best practice as it makes the content easier to read, especially for people with visual impairments. Larger font sizes enhance readability and ensure that the email content is accessible to a broader audience. This practice aligns with accessibility guidelines and helps create a more inclusive email design.
