Sending email to CSV
I'm very new to Braze and trying to figure things out. I did User Import and uploaded a list of 50 people. It says 50/50 success below. When I create a segment and choose this list it now says I...
Hey Julia,
there might be several reasons why you have only 31 people in the segment. When you upload a CSV file, you need to include an "external_id" or "public_id". If the user does not exist, it will create a new user. If you don't have an external_id you can use "user_alias_name" and "user_alias_label". From the Braze documentation: "An alias serves as an alternative unique user identifier, and can be helpful if you are trying to market to anonymous users who haven’t signed up or made an account with your app."
If you have doubled email addresses or doubled external_ids in your list this can reduce the total amount of people in the segment. However, it's hard to say why you have only 31 people in the segment without any details to the segment creation and the CSV file. Maybe some of them don't have an external_id? Then you have to use an alias name.
I would suggest to create the segment directly with the CSV import. You can do it by enabling "Import users in this CSV and also make it possible to retarget this specific batch of users as a group." and "Automatically generate a segment from the users who are imported from this CV." during the upload process.
If you have further questions or need further help, please share more details of your CSV file and the Segment settings.
Hope that helps 🙂
