Bulk SMS Software Features

Before proceeding with building an SMS gateway server, let’s find out what basic and advanced features should such an application have to meet the needs of the prospective customers, or be used by the creator internally. Below are the main features of a bulk SMS service divided by categories. 

SMS Management

  • Create an SMS. This is the core feature from which all the further interaction with the system begins.
  • Sending SMS to groups/individuals. This is another essential feature that should already be customizable, allowing the user to flexibly manage sending options and recipients.
  • SMS history. Everything is pretty clear with this feature  – it is necessary to stay aware of the sending progress and previous SMS marketing activities.

Contacts Management

  • Sender ID customization. With the help of this feature, the companies can send SMS using their branded or employee name. 
  • Upload contacts. To make SMS marketing effective, there is a need to constantly expand the customer numbers database, and add them to the bulk SMS system. That’s why the SMS software should be compatible with Excel Spreadsheets or CVV files for quick data transfer, plus integrated with Customer Relationship Management for automatic uploading and data exchange. 
  • Phone number validation. Most of the already developed SMS services charge the users for SMS sent to invalid numbers. So, it makes sense to validate the phone number before adding it to a mailing list, even when you are using the software created on your own to eliminate mistakes and avoid overloading the lists with non-existing recipients. 

Advanced Features

  • Scheduled delivery. Scheduled delivery makes a lot of sense when paired with data analysis. For example, you can schedule a sending when the open rate becomes as high as possible. That’s why entertainment and hospitality companies share their promos during weekends
  • Personalized messages. The opportunity to personalize messages and develop promo offers based on the user’s previous behavior and purchase is another way to streamline sales and keep your customers highly engaged. 
  • Attachments. Sending attachments like GIFs and other visuals is another way to improve SMS engagement, so this feature makes sense as a part of an advanced set. 
  • SMS marketing campaigns management. Managing the whole campaign using bulk SMS services is another advanced feature the companies are likely to appreciate. 
  • Advanced reporting. SMS marketing campaigns management makes even more sense when there is an opportunity to instantly track the core metrics of success, like open rate, click-through, and conversion rate. User behavior data analysis and insights extraction with the help of AI is one more advanced reporting feature to think about.
