Revenue Per Thousand Impressions (RPM)
Revenue per thousand impressions (RPM) is a metric most commonly seen in advertising. Advertisers use RPM to evaluate how much revenue was generated for every 1,000 ad impressions served. While it’s traditionally been seen as an ad metric, more and more companies are beginning to use RPM as a way to evaluate the performance of many marketing channels, especially email. The metric allows for performance measurement agnostic of list growth, so you can view the true effectiveness of email or other campaigns.
