1. Too informal language
Informal vocabulary, joviality and addressing prospects or media partners in an over-familiar manner will devalue you in the eyes of the addressees. According to the INC.com server, this style might correspond to your company's line of business but everything has its limits.
Remember that not everybody likes joviality and many people immediately see someone who speaks too informally as unprofessional.
2. Grammatical mistakes
We understand there are people who have a problem with grammar and correct spelling. But your e-mail templates should always be mistake-free. If you are not sure how something is spelt, take the time to search for the rule.
Some people (by no means small in number) are very sensitive to grammatical errors.
3. Missing attachments
Before hitting "Send", go through your e-mail and at every sentence in which you mention an attachment, make sure that the file is really there. Missing attachments are a typical sign of a lack of attention and sense for detail.
4. Errors in addressing, dates and names
If you have an incorrect name of the addressee, another person or the company either in the subject line or main body of the e-mail, you might be heading for trouble. If people recognise you are just sending them a modified e-mail that was originally written for someone else, they might justifiably feel insulted.
Always make sure that all the names and dates in your e-mail are correct.
5. Sending e-mails before you have finished them
It must not happen that you send an e-mail to the addressee before it is finished. Typically, your signature might be missing.
If you have this problem, learn to write the e-mail without having the e-mail address stated in the addressee line, and only put it there once you have finished thoroughly checking the message.
