Use Email Subjects with Substance.

To get better results from your Emails, tell your recipients what they will get out of reading your message. Whether you are sending an email to 1 or 1000, draw them in by being direct.
Examples of better Email subjects:

• The B-to-B Networking Lunch not to miss
• How not to make resolutions in the New Year
• Attract new clients effortlessly—free TeleClass
• Stop data entry - scan in hundreds of networking contacts- easily

Avoid filler words in your subjects like hello and greetings. Shy away from ambiguous phrases like “don't you just love it?” Avoid provocative language that is likely to get filtered out by the spam filters.

And of course, watch your email for more gems!
