The Sender ID, or the SMS Originator or sender name, is the name or number displayed on your mobile device that identifies who sent the text message. Think about it as the name or number you see before you even read the message.

Promotional senderids are for sending bulk SMS messages. Broadcast one message to many numbers. Using private sender IDs in promotional text messages is important for making your brand or business stand out and trustworthy so more people will open and read your messages.

It's also important to send promotional texts periodically when there are time-sensitive things going on, so that using custom sender IDs can have a big impact on the audience you're targeting.


Transactional senderids are for sending single SMS message, one message to one number at a time. They are used for sending important and time-sensitive notifications like order confirmations, delivery updates, appointment reminders, critical alerts and one time passwords (OTP).

Using these sender IDs can help build trust with customers by providing critical information quickly. Transactional sender IDs are whitelisted and bypass Do Not Disturb lists (DND/blacklist).

Using transactional sender IDs for promotional messages may lead to financial penalties and permeant ban, because it is against the regulatory rules.
