Just read an interesting article on best email engagement times from http://blog.getresponse.com/be.....aphic.html

Highlights:

• Emails have the best results within the 1st hour after delivery. This is when 23.63% of all emails are opened. But 24 hours after delivery, the average open rate is close to zero.
• 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.
• Messages sent in the early afternoon have a better chance of being noticed and consequently achieve better results: up to 10.61% open ratio and up to 2.38% CTR.
• Subscribers’ top engagement times are 8 a.m. – 10 a.m. and 3 p.m.- 4 p.m. with up to 6.8% average open rates and CTR.

It's a bit of extra work but it does make me consider sending out crucial messages independently to east and west coast time zones. Here's how to do it with Aweber: http://www.aweber.com/blog/ema.....e-zone.htm
