A list is a file containing identifiers for existing contacts that can be imported into your account and targeted immediately. Each identifier must be associated with an existing contact in your Simon account.

Is this the right CSV upload method for your use case?

Be sure to read through the use cases below before moving on to upload.

Use Cases

There are a few ways to upload data into Simon via a .csv and it’s important to know the differences between them so you can quickly get what you need out of the platform.

My CSV has a list of emails with other fields that I would like to use for segmentation and/or personalization.

• The CSV can be uploaded as a contact dataset with the option to source the data from an upload instead of a database.
• The additional fields will need to be named and set for use as condition and/or content (segmentation and/or personalization).
• This option will require a full refresh before it becomes available for use.

My CSV has a list of emails with no other fields and I would like to use it in segmentation alongside existing fields or segments (e.g. suppression).

• When creating a dataset, choose Contact Segment.
• This will require a refresh to use.
• When in the segment builder, search for customer segment and your new dataset will be in the drop down that appears.
• This is best used for suppression groups.

My CSV has a list of emails with no other fields and I would like to use it in segmentation but do not need to mix it with other criteria.

• The quickest way to target an audience from a CSV is the list upload feature. This allows you to upload a list of emails and make them available for segmentation in just a couple of minutes, instead of having to wait for a refresh. However, it cannot be mixed with any non list-upload segmentation criteria so you will only be able to use the CSV as your audience for taking actions.
  • Note: Emails must be present in Simon already.

My CSV does not have a list of contact information.

• A lookup table is likely the route we will go here. Contact your account manager for alternative workflows.

Lists for immediate use

You can create a upload list to immediately create a flow or journey with a list of contacts, however these contacts will not be saved for future use. CSV is the way to go if you're planning on using these contacts a lot.

Dos and don’ts

If you're uploading a CSV with more columns than just email address, ensure the additional fields aren’t already in Simon, and/or the fields that will actually be used.

• CSVs are commonly uploaded with extra fields which then become new properties for all contacts in Simon. For this reason we recommend that CSV uploads contain no columns other than email unless it’s needed for the campaign and can’t be pulled into Simon from a database

How to find a .csv uploaded as a Contact Segment

• Contact segment CSV uploads can be found in the segment builder under Customer Segment. Use the search box to find your uploaded dataset.

File format

A list should be uploaded as a file with a ".csv" extension. The file should contain a single column with no header and only identifier.

🚧

Usage and limitations

Lists may be used as an include condition with the definition of a segment, and cannot be used as suppression. These segments can be used to message audiences using One-Time flows only.

A segment may only use one List as a condition in the definition. Additionally, a segment that references a List in its conditions may not be used as a base segment or referenced by another Segment.
