This is a very common question !! What is the difference between promotional and transactional gateway.
Last year TRAI has come up with a category called Transactional SMS to curb the unsolicited communication. We have already described this in an earlier post
Unfortunately, TRAI has not defined what is Promotional SMS category. Therefore, any message apart from transactional sms category is called promotional sms.
Over and above, its the content which decides the category of SMS apart from from who is sending SMS. For example, a registered Bank is eligible to send Transactional SMS as per TRAI, however they can can not send any promotional content to their registered customers through Transactional channel.
Example: The following example illustrates the two different type of sms sent by a bank
Transactional: Dear customer your account balance is Rs 55555. Regards. ABC Bank.
Promotional: Now get 4.5% interest on all your fixed deposit. Regards. ABC Bank.
