Mailer Mailer recently came out with an infographic based on their recent Email Marketing Metrics report. With the data they compiled, you can see the success of what time scheduled emailed work best and how well subject lines perform based on the number of characters in it.
For instance:

• 70% of messages are opened within the first 16 hours
• Messages scheduled for Sunday had higher open and click rates as did ones that were scheduled for midnight.
• 15.2% of messages with 4-15 character subject lines

How does this infographic match the results of your own personal testing? Are you sending your emails at the right time? Are you optimizing your email strategy? A well timed email can make a big difference for your integrated campaigns.
