When incorporating emojis into SMS campaigns, it’s essential to consider their impact on the encoding standards.

In today’s digital landscape, emojis have become integral to modern communication, adding depth, emotion, and context to text-based messages.

When incorporating emojis into SMS campaigns, it’s essential to consider their impact on the encoding standards: GSM-7 and GSM-8, which dictate character limitations and encoding compatibility.

Here’s a comprehensive guide on leveraging emojis effectively in SMS campaigns while navigating the intricacies of GSM-7 and GSM-8 encoding:

Understanding GSM-7 and GSM-8 Encoding

GSM-7 is a character encoding standard widely used for SMS messaging. It supports a limited character set of 128 characters, including alphanumeric characters, common symbols, and basic punctuation.

Emojis are not directly supported in GSM-7 encoding, as it lacks the necessary characters to represent them.

GSM-8, also known as UCS-2 or UTF-16, is an encoding standard that supports a wider range of characters, including emojis and other Unicode characters. It allows for the representation of up to 65,536 characters, making it suitable for languages with diverse character sets and symbols.

How Emojis Impact SMS Campaigns

In GSM-7 encoding, each character occupies 7 bits, allowing for the transmission of 160 characters per SMS. However, when emojis or non-GSM-7 characters are included, messages may be limited to 70 characters per SMS due to the need for GSM-8 encoding.

This reduction in character count can affect message clarity and content delivery.

When an SMS message exceeds the character limit imposed by GSM-7 encoding, it is automatically segmented into multiple parts by the network.

This segmentation can lead to fragmented messages, especially when emojis are involved, as they may require GSM-8 encoding and consume more character space.

Cost Considerations

SMS messages exceeding 160 characters (or 70 characters with emojis) are billed as multiple messages by most mobile carriers. Therefore, incorporating emojis may increase the overall cost of SMS campaigns, especially if message segmentation occurs frequently.

Compatibility Challenges

While modern smartphones and messaging apps support a wide range of emojis and Unicode characters, compatibility issues may arise when sending SMS messages to older devices or platforms that do not fully support GSM-8 encoding.

Emojis may appear as question marks or garbled characters on such devices.

Best Practices for Using Emojis in SMS Campaigns

Use emojis strategically to enhance the emotional impact and visual appeal of your SMS messages. Prioritize commonly supported emojis that are more likely to render correctly across devices and encoding standards.

Test Across Devices

Before launching SMS campaigns, test messages containing emojis across various devices, operating systems, and messaging apps to ensure compatibility and readability.

This proactive approach helps identify potential rendering issues and allows for adjustments as needed.

Message Formatting

Keep messages concise and avoid excessive emoji usage to minimize the risk of message segmentation and associated costs.

Strive for clarity and coherence in your messaging, balancing text and emojis effectively.

Monitor Campaign Performance

Analyze engagement metrics and feedback to assess the impact of emojis on your SMS campaigns.

Measure factors such as open rates, click-through rates, and conversion rates to determine the effectiveness of emoji usage and make data-driven adjustments.

By understanding the implications of emojis on GSM-7 and GSM-8 encoding standards and implementing best practices, you can harness the power of emojis to create compelling SMS campaigns that resonate with your audience while ensuring compatibility and message integrity across diverse devices and platforms.
