To find out, Ryan Solutions looked at 12,000 resort and hotel email campaigns sent to over 300,000,000 recipients during 2015 by over 100 different hotels and resorts. The company grouped these sends by number of recipients and found the average open rate for each group. For its sample, emails sent to groups of 1,000-5,000 saw open rates that were almost double those sent to 250,000-500,000 (27.6% vs 14.8%). At every step along the graph, larger campaigns saw a decrease in average open rates. The takeaway, however, isn’t a reason to send fewer emails, it’s simply to send better targeted emails.
