Hashing email lists for AdWords Customer Match

rapidminer_adwordsGoogle AdWords Customer Match lets you target email lists for remarketing purposes.

RFM for email senders – a step-by-step guide to a more strategic messaging approach

RFM stands for Recency, Frequency, Monetary Value. It’s a simple and yet effective customer scoring algorithm that has been used for about a hundred years, now.

Email marketers do also use RFM analysis. Less, to save costs (email is “for free”), but more to predict subscriber values and to: Continue reading

Email pre-testing: Determining required group sizes and margins of error

When testing, it’s a good idea to have some formulas to hand. For instance in split A/B/n test scenarios, you may want to inspect the relationship between sample size, level of significance, and power. Also when renting lists, no one likes to buy a pig in a poke. Instead, the campaign has to be tested on a small segment first. Only if the test turns out to provide a good return on investment, the full run will be booked.

However, the question is, how many recipients should one book for the test? Including too many recipients would only cost in case the list proves to be unprofitable. Renting too few subscribers on the other hand bears the risk that the test results are due to chance. Here’s a hands-on solution. Continue reading
