THE OPTIMAL EMAIL MARKETING FREQUENCY

Summary from the TLDR Marketing newsletter

Sending 7 emails monthly is the optimal frequency for maximizing customer lifetime value. Reducing this to 4 emails cut lifetime profit by 32%, while increasing it to 10 emails reduced profit by 16%. The best results come from tailoring email frequency by purchase behavior, sending 5-7 emails to frequent buyers, 6-10 to medium buyers, and 12-14 to infrequent buyers. Frequent buyers tend to ignore more emails, while occasional buyers engage more when they receive additional messages.
