SMSLocal: Empowering Long Text Messages for Seamless Communication

Long text messages, sometimes referred to as long SMS or concatenated SMS, are messages longer than the 160-character limit imposed by most carriers. While 160 characters may seem short for personal communication, it can be very restrictive for business use cases like sending promotions, announcements, alerts, multi-step instructions, etc. Thankfully, modern SMS software and gateways like SMSLocal allow sending long text messages seamlessly while optimizing deliverability.

What is a Long Text Message?

A long text message is any SMS longer than 160 characters (140 bytes). Most mobile carriers divide messages longer than 160 characters into 153-character segments, called concatenated SMS, so they can be recombined on the receiving device into one long message.

For example, a 300-character SMS would be sent as two 153-character messages and displayed as a single 300-character message on the recipient’s phone.

Benefits of Using Long Text Messages

Long text messages have many benefits compared to standard 160-character SMS:

  • Convey more information: With over 2x more characters, long text messages allow communicating complex ideas, detailed instructions, in-depth explanations, etc. This leads to better engagement.
  • Improve open rates: Recipients are more likely to open and read long informative messages compared to short generic ones. This increases response rates.
  • Deliver promotions: Long SMS can include detailed product/service descriptions, offers, coupon codes, website links, etc. ideal for marketing campaigns.
  • Send alerts and notifications: Long text message memes can provide context and detailed notifications for order updates, account changes, delivery alerts, etc.
  • Guide users: Step-by-step instructions, directions, troubleshooting tips, etc. are only possible with long text.

Examples of Using Long Text Messages

Here are some examples of effective uses of long text messages:

  • Welcome messages to new app/service users explaining features and settings
  • Appointment reminders with location maps and contact information
  • Shipping notifications with tracking info and delivery estimate times
  • Restaurant menus showcasing daily specials and new items
  • Class/event reminders with schedules, room numbers, speaker bios
  • Retail coupons with product images/descriptions and discount code
  • Password reset instructions with a reset link and steps
  • Automated chatbot conversations with contextual responses and questions

Best Practices for Long Text Messages

Follow these best practices when crafting and sending long text messages:

  • Lead with value: Start with the most useful info like offers, event details, alert reasons, etc.
  • Get to the point: Be concise and don’t make recipients scroll to get to the meat of the message.
  • Personalize: Use merge tags to include names, locations, purchase details, etc.
  • Use images wisely: Include only small, compressed images when necessary to augment text.
  • Make it scannable: Use bullets, lists, headers, and emphasis formatting to improve scannability.
  • Provide options: Include links, phone numbers, shortcut codes, etc. to provide value and get a response.
  • Test thoroughly: Check rendering on all major mobile platforms during QA. Use an SMS validator.
  • Segment audiences: Customize messages based on user preferences, demographics, past interactions, etc.
  • Analyze results: Use SMS analytics to identify popular messages and continuously improve campaigns.

Structuring Long Text Messages

Since long texts cannot be scanned as easily as short ones, structure is important. Here are some tips:

  • Start with a descriptive heading summarizing the content
  • Use numbered lists for step-by-step instructions
  • Break into paragraphs with blank lines for sections
  • Bold or italicize keywords, titles, and references for emphasis
  • Place links, phone numbers, etc. on their line for visibility
  • End with a call-to-action reminding recipients of key info

Keeping Long Text Messages Engaging

To maintain recipient engagement in a long text message, consider employing a variety of formatting techniques. Strategically incorporating emojis can help convey tone and emphasis, while relevant images, GIFs, and videos add visual interest when applicable. To break up the text and enhance readability, alternate between paragraph styles, such as bullet points, numbered lists, and headers. Utilize contractions and an active voice for a more casual and approachable tone. 

However, it’s important to limit the use of hard-to-read ALL CAPS, excessive return spaces, and special characters. Additionally, inserting questions and prompts can encourage recipient responses, fostering interaction. To keep the content engaging, sprinkle in interesting facts, statistics, and quotes related to the subject matter, creating a captivating and informative long text message meme that resonates with your audience.
