E-mail, however, is not a good medium for conveying information that will provoke a strong emotional response from the recipient or for explaining detailed, complex topics. Use humor sparingly. E-mail is akin to a business speech. Humor can spice up the delivery, but the writer has to be careful not to offend. Check the recipient's preferred mode of communication.
Some people respond more quickly to an electronic communication than to a voice mail message.
Others have an e-mail box but do not check it often. Be certain that the vehicle you choose to convey your message suits the audience you are addressing. To keep your customers satisfied, you should promptly respond to all e-mail messages. People corresponding by e-mail typically expect responses within three business days. If you are unable to respond in a timely manner, do not publicize e-mail as a way to contact you or your company.
