SMS Delivery and Deliverability Explained

Learn how to optimize SMS delivery rates, avoid delivery failures, and enhance SMS campaign success with actionable strategies.

SMS remains one of the most effective communication channels, boasting impressive engagement and open rates. However, the success of any SMS marketing campaign heavily relies on its SMS delivery—the process of ensuring that messages reach their intended recipients without fail. This blog will break down everything you need to know about SMS delivery and deliverability, from understanding delivery rates to overcoming common issues.

‍

What is SMS Delivery?

SMS delivery refers to the successful transmission of a text message from the sender to the recipient’s device. While it sounds simple, multiple factors influence whether your messages are delivered successfully. These factors include the accuracy of phone numbers, network reliability, and the recipient’s device status.

Delivery success is often measured through SMS delivery reports, which confirm whether the message was received. For more on how delivery reports work, check out our guide on SMS marketing best practices.

‍

Understanding SMS Delivery Rates

Your SMS delivery rate is the percentage of messages successfully delivered to recipients. It’s calculated using the formula:

Delivery Rate=Messages DeliveredMessages Sent×100\text{Delivery Rate} = \frac{\text{Messages Delivered}}{\text{Messages Sent}} \times 100Delivery Rate=Messages SentMessages Delivered​×100

Delivery rates offer valuable insights into the effectiveness of your campaign. Low delivery rates may indicate issues such as invalid phone numbers, network problems, or spam filters. Learn more about avoiding these pitfalls in our blog on the 8 biggest mistakes to avoid when creating an SMS marketing plan.

Common Causes of SMS Delivery Failure

Even with the best systems in place, some SMS delivery failures are inevitable. Here are a few common reasons:

1. Invalid or Incorrect Phone Numbers
   Ensure your database is up to date and contains accurate phone numbers. Using a reliable SMS platform can help validate numbers before sending.
2. Spam Filters
   Carriers often block messages that appear spammy. To avoid this, follow guidelines for SMS opt-ins and always include opt-out instructions.
3. Device Issues
   Sometimes, the recipient’s phone may be switched off or out of network coverage. Delivery reports can help identify these scenarios.
4. Carrier Filtering
   Messages flagged for inappropriate content or sent to restricted regions may be blocked. Optimize your campaign with tools that ensure compliance, as highlighted in our mobile marketing automation guide.

The topic of A2P 10DLC (Application-to-Person 10-Digit Long Code) fits perfectly under the section “How to Improve SMS Delivery Rates.” It is a significant factor in ensuring better SMS deliverability for businesses and aligns well with the strategies to optimize delivery.

‍

Using A2P 10DLC to Improve SMS Delivery Rates

One of the most effective ways to enhance SMS delivery rates is by leveraging A2P 10DLC. A2P 10DLC is a system designed specifically for businesses to send messages via standard 10-digit long codes, offering improved deliverability, compliance, and message throughput.

‍

What is A2P 10DLC?

A2P (Application-to-Person) 10DLC enables businesses to send high volumes of SMS messages through a dedicated 10-digit phone number. Unlike traditional long codes (P2P or Person-to-Person), which are designed for individual use, A2P 10DLC supports business-level messaging with the following benefits:

• Better Deliverability: Carriers prioritize A2P 10DLC messages over P2P traffic, reducing delivery failures.
• Higher Throughput: Businesses can send more messages per second, ensuring timely delivery of campaigns.
• Compliance: A2P 10DLC complies with carrier requirements and helps avoid spam filters, which can block bulk SMS messages.

‍

How A2P 10DLC Improves SMS Deliverability

1. Enhanced Carrier Support: Messages sent via A2P 10DLC are less likely to be flagged as spam or blocked, as carriers recognize them as legitimate business traffic.
2. Brand Transparency: Businesses must register their brand and campaigns, improving accountability and fostering trust with carriers.
3. Reduced Filtering: Proper registration ensures that messages bypass unnecessary filtering, especially for promotional or transactional SMS.

‍

Implementing A2P 10DLC in Your SMS Strategy

To integrate A2P 10DLC into your campaigns:

1. Register Your Business: Ensure your brand and campaigns are registered with the appropriate carrier programs.
2. Optimize Your Content: Use compliant, non-spammy language, and always include opt-out options.
3. Choose the Right Platform: Partner with SMS platforms like Dripcel that support A2P 10DLC and provide tools for compliance and optimization.

The Role of SMS Delivery Reports
