I'm trying to an Automation using a file drop. Technically, I listen for a specific drop file, file transfer because it is encrypted-> import the file -> insert the data into DE using SQL query. Would like to send a welcome email to new contact that I have inserted into DE only.

Do I use filter? Or how can I tell Automation Studio send only to new inserted member.

When using the Import Activity set the Update Type to "Overwrite". This will clear the existing records of the Data Extension and import all the records in the file.

  • I see your point. However, I don't want to clear the previous data as well. For example, every week I would like to update the data extension with new data. So I'm not deleting the previous one. All I want is whatever data I have added into DE, send an email to these contacts.

  • Yes, this is a common scenario. Here's what I would do: Create a new Date field in the Data Extension and set the default value to "now" (it's a tick box on the field). This will ensure that all new records coming in will be timestamped as they enter. Next create a query or data filter which only searches for records in the Data Extension that have been timestamped (read: added) since yesterday. Output the results of the query or filter into a Data Extension and only send to those on a daily basis at a send time of your choosing. Apr 5, 2017 at 21:06
  • Fair enough that was my approach
