Did you know that there are some rules for an effective Bulk SMS campaign? An SMS which includes an irresistible offer with a proper call to action is not very effective. You need to specify your brand name explicitly with the location where the offer can be redeemed. Think about an offer that is not a limited time offer; do you think any of your audience will run to the store to redeem it? The answer is a big NO! So don't forget to create a sense of urgency while also presenting your offer as something very exclusive.
