Promotional SMSDND (Do Not Call) Registry –In India, it’s not necessary that you can send message to every user who is listed on your list because users or customers in India are given an option to register themselves under DND services where once they register, they’ll not receive any promotional SMS. Each user can register for this service with their telecom service provider. Specific Time Window –In India, the time window from 9:00 am to 9:00 pm is defined to send the promotional messages. Before and after, no messages can be sent, so be sure to make a request in advance for sending promotional messages for your business through Bulk SMS providers.
Following The Specific Format For Phone NumberIn India, if you are using promotional SMS services for your business then your message will be sent using a specific short number coding format like “YY-ZZZZZZ” where first two letters of the code define the provider and area. With this sender ID format, no recipient can reply back to the sent message. In promotional messaging, it is always one-way messaging in India.
Limitations on Number Of MessagesTo avoid SMS spamming or flooding, there needs to be a gap of 20 minutes for every same promotional message i.e. same text body from the same sender to the same receiver. If you need to send messages more frequently, then it is better to get two different numbers with different shortcodes.
Transactional MessagesWe have already defined what exactly transactional messages are but apart from that it also needs to fulfill the following two requirements,
- It is required that transactional messaged should be sent from pre-registered sender id, that need to be in alphabetic format.
- Since March 2019 in India, all transactional messages are required to use a pre-registered white-listed message template that you’ll be giving to your service provider. If you violate this rule, then you may face legal challenges’ or penalties’, blocking off the registered sender id by the service provider and fine from the telecom carrier.
- Name of your company
- Company registered address
- Your website
- Your email-id
- Headquarter details i.e. whether in India or outside India,
- SMS white-list template format
- Project details or use-case description i.e. for what purpose you need it that will be viewed by the carrier for approval. Once you have all this data in your hand, contact and submit the same to your service provider.
