MailerMailer released its ninth bi-annual Email Marketing Metrics Report today, highlighting the latest trends in email marketing. The 38-page report is filled with charts, tips and data that provide businesses with relevant information to help them adjust their email marketing strategy to cater to their audience's changing needs.

Perhaps the most interesting takeaways are the most frequently-seen terms used by marketers in email subject lines. The top 10 most popular terms were 1) news, 2) party, 3) newsletter, 4) free, 5) night, 6) sale, 7) com, 8) update, 9) holiday, and 10) week.

Other interesting points included in the report:

  • Emails are being opened sooner: 32.6% of all opens occur within the first two hours, compared to 29.6% six months prior
  • Click rates held steady, rising just slightly by .08% in the second half of 2008
  • Email deliverability keeps increasing -- more emails are reaching recipients' inboxes
  • Religious/Spiritual emails are getting the highest open and click rates compared to other industries

"The key to leading winning campaigns in the midst of a recession is to move with the ebb and flow of changing subscriber preferences," says MailerMailer CEO Raj Khera. "Our report covers many important trends marketers need to be aware of to make strategic decisions in running their campaigns."

Interesting how the most frequnetly seen term is news rather than something related to 'free' or 'sale'. I wonder what words were most popular in past years.

This terms were the most popular but I guess not the most attention getters.

I think the term "newsletter" is popular because that's the sugested title on some mass email softwares, but I wonder if the word is relevant to the reader.

I name my newsletters with the term 3D comic or 3D comicbook and not the name of my website or newsletter because my email address already contains the word newsletter and my domain name. I don't really care much about my readers knowing it's my newsletter they are getting but I try to be recognizable from the title and provide something that interests them, I always look at the title and skip the address of emails I receive, I think many of us do that. Do you do the same?

From the newsletters I've subscribed to, Animation Magazine's is always the one I can't skip, they include the most important news on the title and wake up my curiosity.
