There is the saying, 'Timing is everything'. There are two important aspects of timing that you should pay attention to if you really want your SMS campaign to be successful.
First, open-ended messages are less successful than messages that have deals that expire. For instance, a text message like
Wow!! Check out our designers men's outfit such as Turkey Shirts, Stock Jeans & Polo, Italian Shoes etc @ Shop 123 Alaba Market. For inquiries, call 08181610450
is less likely to get better response than
Get 50% Off all purchases TODAY on any of our products (Jeans & Polo, Turkey Shirts, Italian Shoes etc) @ Shop 123 Alaba Market. For inquiries, call 08181610450.
Create the text of your SMS to portray that the deal “expires soon” or something similar.
The second aspect of this tip is - you need to make sure your SMS messages are sent at opportune times.
For example, when someone buys a particular product, you could send him or her an SMS message about a related product in hopes of getting him or her interested.
If you have got wedding sms to send out to your friends and relatives, what time do you think will be ideal to send it?
Finally, there is no straight-cut rule to when you should send your sms. Factors like 'the purpose of sms' and 'the audience you are sending your message to' will go a long way in deciding when to send your message.
Best Rule is 'Use your Discretion'.
