How can I improve SMS deliverability?

We use the leading provider in the SMS market to send your messages. However, countries tend to be very strict when it comes to automatic SMS. Therefore, here are a few tips you should follow when defining the content of your messages:

  • Keep the messages short (ideally, they should fit within the 160 character limit).
  • Avoid vulgar/offensive words or slang. Some carriers may categorize those messages as spam and block them.
  • Do not include any political words. Some carriers may block the messages directly.

You can also use our pre-defined messages that were written to improve deliverability.
