1. Be careful with abbreviations--Texting is meant to be a fast form of communication, so it's common to use abbreviations and shortcuts such as "LOL" (laugh out loud), "np" (no problem), or "u" (you). But there is such a thing as an inappropriate abbreviation. If you choose to use them, only use the ones that are widely known. A good rule of thumb is to only type what you would be comfortable saying out loud. Ultimately, the safest route is to type out the entire word or phrase.
2. Be aware of your tone--When you're writing short and fast, you're not thinking about your tone and your text may sound harsher than you intend. Try to write in complete sentences to prevent sounding abrupt and always read your message out loud to make sure it doesn't sound too harsh. Avoid negative words such as "failure," "wrong," or "neglected." Instead, use "please" and "thank you."
3. Never send bad news via text--Don’t give negative feedback or quit your job in a text. In both cases, speak to somebody. Even if you are leaving a company, you don’t want to burn your bridges because you may need a reference in the future. The bottom line is that texting is too casual to give bad news. It's difficult to know what tone you're giving off in a text message, so it's safer to stick to only good news when sending texts to people in your professional network.
4. Don't change meeting times or venues in a text--The potential attendees may not check their phones in time. Older workers may not look at their phones as often as younger people. If you're going to change a meeting time or venue at the last minute, give the person a call out of respect.
5. Always double check when using the voice-to-text feature--Smartphones let you speak your message, which the phone converts to text. But a lot can be lost in the translation. Make sure that what you said is what is showing as text before you hit the send button. You have no idea what voices your phone may be picking up. It could be a conversation nearby or even lyrics from a song on the radio. It might be a bit confusing for your professional contact to get messages from you that read like the latest Beyonce single.
