Make sure you follow best practices when you collect your customer's phone number and consent. By providing consent data to Zaius, you can ensure your customers don't receive any unexpected messages. ## Message Segments The SMS protocols at the telephone carrier level have limitations. 160 characters per messages for standard messages, or 70 characters per message if your message contains non-latin characters, such as emojis or characters from Asian or Eastern European languages. Most phones will re-combine the messages so it's not often noticeable by your customer, but each message segment is billable, so it's important to be aware of your message lengths.
