MarketingSherpa is reporting six actions that can help increase the number of open & click-through rates of Email campaigns and newsletters. The findings are from MailerMailer's new Email Marketing Metrics Report, in which they analyzed nearly 270 million opt-in email newsletters and campaigns sent by a sample of over 3,000 MailerMailer customers in the first half of 2007.

The report provides some good insight into Open & Click Rates by Industry, Open & click rates by day, Open rates by Subject Line Length and open rates by day of the week emails were sent. Retail Industry is doing pretty well in second place by click rates.

Lots to get and improve by getting the report. Highly recommended.
