In January 2018, we started a project that entailed recording every email we sent for our clients: 3,089,124 emails across 1,697 campaigns for 43 clients over 21 months, to be exact.

Our goal was to compare our clients’ results to the posted industry benchmarks to see if they were a good judge of success.
