List Maintenance Programs allow you to make automated changes to your lists. They're useful for injecting values, such as lead score, into a list field so that you can use them for segmentation, sending, etc.

Common Uses of List Maintenance Programs

Recording data for hard bounces, soft bounces, etc. to sync to your CRM
Changing a specific field value for every record in a segment
Injecting campaign scores into a segment
Incrementing a field to count every time a behavior occurs.
Setting a timezone on a contact record
Recording a date when a contact takes action or qualifies

List Maintenance Programs accomplish many of the same functions as Automated Programs, which can also change a field. Automated Programs generally run once on a contact, and should be used if you want a field to change one time and not be updated (such as the original lead source). List Maintenance programs can run on a schedule and update daily for data that changes regularly (such as campaign score). In addition, List Maintenance has more options for setting field values, including campaign score, timezone, increment, decrement, clearing the field value, setting to today's date, or using personalization values to copy data from other fields.

Best Practices for List Maintenance programs: Because these programs can run daily, it's best to limit the source to contacts who really need action to be taken. For example, if you want to update contact records to add a timezone, create a source segment of contacts with a blank timezone field. This will limit the amount of processing the program has to do and will only update contacts who need it.

Instructions

Create a New Program

Navigate to Automation > List Maintenance Programs and click the '+' New Program button on the right.
Enter a Program name and description for the List Maintenance Program.
Select your schedule, Manually or On a schedule. Scheduled programs can run daily, weekly, or monthly. It's best to run list maintenance programs during off-business hours (when you are not sending emails).
Click Continue:
Select your source segment. This is the set of contacts you want to run through the program. Only one segment can be selected for each program.

Tip: If you schedule the program to run Daily, Every Hour, or use a Start Time of Noon, the program will only run hourly between the hours of Noon and Midnight each day.

Select options:
- Append copies to the list -the second record with the same email address will be added to the end of the list
- Update records with matching emails - the first record will be updated with any new values. Note that blank values will not overwrite any fields that already contain a value

C. Copy from a Segment step

This step type adds records from another list/segment into your program's list. It is available only for programs based on Marketing Lists.

Select a list or segment to copy from
Choose how new vs. existing records will be handled
- Append and merge – add new contacts to the program list, and add any values to existing records that are currently blank
- Merge – do not add any new contacts, but add any values to existing records that are currently blank
Choose whether to overwrite and/or delete existing data
- Update records – values on the program list will be overwritten
- Remove records if not present in source – remove contacts from the program list if they are not found in the other list.

Managing Your Programs

Point to a program in the list to run it manually, edit it, favorite it, move it to a different folder, or delete it. You can use folders and tags to keep your programs organized.
