Cut down on sigs. Signature files, especially in business, should contain as few lines as possible. Four lines is a figure generally agreed-upon. Email that consists of a two-line statement and a ten-line signature will have its recipients rolling their eyes. 9. May I quote you? When you respond to an email, the original email is quoted. Cut the most relevant sentence from the message to which you are responding, preface it with a '>' (if it's not already there) and paste the quote above your response. Delete the rest of the original email from your response, unless you are responding to other points in the original. 10. Don't use email when you are angry. This is a tip from Joan Tunsall's Better, Faster Email (non-affiliate Amazon link). While most of the time email does not convey your emotions, particularly humor, it somehow seems to transmit anger - even when you donâ€™t intend it to come through.. 11. Get clarification. If someone sends you an email sender that upsets you, make sure you haven't misunderstood. As mentioned previously, emotion and tone do not always carry over well in email. Instead of responding angrily, in your response, quote the portion of text that you are unsure of and ask the sender to clarify. Indicate what you think it means, if you like, then ask if you've misunderstood. Proofread. There is a difference between typos and poor writing. Poor writing improves with practice. Typos stay typos unless you take the time to eliminate them. If you are applying for a job or freelance gig, it's especially important to prufreed before you send that email. And as if you needed another reason to be concise, remember that the chance of typos is directly proportional to the length of your email. * Between the Q1 and Q2 surveys, there's been a decrease in image spam and an increase in spam that uses PDF, PowerPoint and Excel files. * Marketers sending permission-based emails to US-based ISPs still land in the junk/bulk folder almost 16 percent of the time: About the study (pdf): From a email sender beginning April 1, 2007 and ending June 30, 2007, the Lyris EmailAdvisor service monitored the full delivery trajectories of 436,558 production level, permission-based email marketing messages sent from 69 businesses and nonprofit organizations to multiple accounts at 58 ISP domains in the United States, Canada, Europe, and Australia.

The "Internet" uses DNS (Domain Name System) to resolve Domain Names (as an example www.msexchange.org) into IP addresses. DNS is also used to direct requests for different services like e-mail and Web Servers. For every Domain around the world an MX (Mail Exchanger) record must exist. An MX record tells the email sender where the target server for receiving mail is located. lyris-2q07-deliverability-junk-bulk-delivery.jpg * XO Concentric far exceeds any other ISP - banishing 56 percent of invited email to the junk/bulk folder. * Next in line are SBC Global and Bell South, both junking 30 percent of permission-based email, and Yahoo at 26 percent. * MSN Network, GMail and Hotmail all come in at 18 percent. * Rounding out the top ten are PeoplePC, USA and Earthlink. * At the other end of the spectrum, AOL delivered only 1.94 percent to the junk/bulk folder. lyris-2q07-deliverability-inbox-delivery.jpg * Marketers sending to European ISPs face even more trouble: More than 20 percent of permission-based emails were sent to the junk/bulk folder - almost three times more than the previous quarter.
