Bad habit 1: Spam

Tip: Do not send spam. Sounds very simple, doesn’t it? If your messages are not delivered by a network operator on suspicion of spam, it may help to look at the wording. And: if possible, avoid sending many SMS messages to one recipient in a short time.
Nobody likes spam. It consumes nerves and storage space, and in most cases is deleted after receipt. Nevertheless, companies try repeatedly to draw attention to themselves with spam. In some countries this is prohibited by regulations, and many network operators do not even deliver messages classified as spam. As a result, your company not only loses reputation, but also money.
