How Does Sender ID Impact SMS Delivery?
If you ever receive a promotional or transactional SMS on your phone, you may notice the name on the sender’s end is always related to the business’s name. That name is called Sender ID. It plays an important role in your SMS campaigns. If the name is not familiar or related to your brand, then customers won’t recognise the message as yours. It is the deciding factor if your message is delivered, blocked, or trusted by the receiver. In this blog, we will explain what a sender ID is, how it affects SMS delivery, and why choosing the right one matters.
What Is a Sender ID?
A Sender ID is the name that appears on the receiver’s phone at the top of the SMS they received. It is usually 3 to 6 letters long. It includes the brand name or the company’s identity to make it familiar to the customers. For example, if you receive a text from PAYTM or AMAZON, they will have their names in their sender ID. This lets customers know who sent the message even before opening it.
Why Sender ID Is Important for SMS Communication
You may think a sender ID is just a name. However, that’s not its only purpose. A sender ID is a mandatory quality check because mobile operators use it to check whether the SMS has been sent via a verified business or not. If the operator find the sender ID is not approved or looks suspicious, they will never let your SMS reach the customers. A correct sender ID improves message delivery rate, customer trust, and SMS open rate. You will be unable to run your SMS campaign if your sender ID is incorrect.
What is the Difference Between an Approved Sender ID and An Unapproved Sender ID?
In India, it is mandatory for businesses to register their sender ID through the DLT registration launched by TRAI. If a sender ID is approved, it means the telecom operators can recognise your business as genuine. However, if your sender ID is unapproved, does not match your business, or is copied from another brand, your messages may get rejected instantly and will not reach your customers.
How Sender ID Affects SMS Blocking
Telecom operators immediately block messages that use fake or misleading sender IDs, copy popular brand names for their sender IDs, or don’t match the registered business details. Even if your message is genuine, an incorrect or unauthorised sender ID will lead to your SMS getting blocked.
How Does Sender ID Help Gain Customer Trust?
If customers are familiar with your brand’s name, your Sender ID will help them recognise your SMS even before they receive it. If they see an unclear name or one that doesn’t match your brand’s name, they might not even open it. In the worst-case scenario, they might even report the SMS as spam. If your sender ID is clear, it will help you build brand recognition, reduce spam reports, and increase response rate. People always trust messages when they know who sent them.
Can One Business Use Multiple Sender IDs?
Yes, a business can register multiple sender IDs if needed. However, they will still have to register each sender ID officially. Otherwise, they will count as unapproved. Each sender ID needs to be linked with the correct message template. Additionally, using too many sender IDs without any purpose can confuse customers, and they may even doubt their legitimacy.
What Mistakes Should You Avoid?
Even a small mistake can cause big issues. You need to avoid small mistakes, like using special characters or numbers. You should also avoid choosing a name that’s not related to your business. Wait for your sender ID’s approval before sending SMS, or your messages will get rejected. Businesses should also avoid changing their sender ID continually.
Final Thoughts
Sender ID directly affects the delivery of your SMS campaign, trust, and success rate. A sender ID should be approved by the DLT registration and have a clear name that is related to your business. If your sender ID is clear and makes your customer recognise your brand, they will trust your campaigns instantly. It may look like a small detail, but it’s one of the most important things for a successful SMS campaign.
