Why is my prospecting campaign holdout less than 20%?

Though it is rare, there are some instances in which we're not able to source a holdout group that is the full 20% of your mailing group. Some factors that could cause Poplar to be able to source fewer addresses than expected:

• The chosen overlays are very specific and niche
• Large overlap of your customers and/or suppression lists with the database, lowering the chance of finding non-overlapping prospects

There are no refunds for holdouts less than the expected amount, because holdouts are free of charge.
