I used sales alert for sms marketing.Another event to draw customers' attention to is sales and clearance. To attract the most customer interest, your sale alerts should include information about what's on sale at a discount, for how long, and at what price. If it's a major sale, such as an annual or semi-annual event, alerting customers with texts leading up to the event will also help create anticipation.
Certain tactics like that can be considered spam and may be restricted by the various phone carriers. As a result, your number can be blocked, which will severely interfere with your ability to communicate with clients.
