In this digital age of widespread connectivity and the ubiquity of smartphones, SMS (Short Message Service) has become an indispensable tool for business communication. SMS offers many benefits and one of the most critical aspects of text marketing campaigns is SMS delivery- messages reaching their recipients as intended.
In this blog post, we’ll explore the factors that affect SMS deliverability.
What is SMS Delivery?
SMS delivery is the process of successfully sending a text message from a device to another. SMS deliverability is a measure of how many of your text messages landed in your recipient’s inbox.
The global number of individuals who send and receive text messages is projected to reach 5.9 billion by 2025. Needless to say, SMS deliverability is critical to the success of your text marketing campaigns. A high delivery rate means your messages are making it to your target audience. Poor delivery rates, on the other hand, can lead to ineffective campaigns and wasted marketing resources.
How do I Know My Messages are Delivered?
You can get delivery reports when you use programmatic SMS API and monitor deliverability rates.
You can check the messages status along with the delivery time. For example, if the message is undelivered, you can find out from the status.
How Can I Get an SMS Delivery Report?
If you are working with an SMS API Provider, then you can get reports of all the messages triggered using the API keys of the account.
