Email marketing solution provider, GetResponse, put together data from 21 million messages sent from US accounts in the first quarter of 2012 to determine top open and click-through times. The firm also analyzed the recipients’ top engagement times to test the thesis that email send times do matter, and that message results depend on reader engagement routines quite a lot.

GetResponse put its data into a pretty infographic – here are some highlights:

– Almost 40% of all messages are sent between 6 a.m. and noon. This can result in inbox clutter, and significantly decrease results for these emails.
– Sending newsletters during readers’ top engagement times of 8 a.m. to 10 a.m. and 3 p.m. to 4 p.m. can increase average open rates and CTR by 6%.
– Messages sent in the early afternoon have a better chance of being noticed and achieve better results: up to 10.61% open ratio and up to 2.38% CTR.
