We suggest running templates through Sakari. Often, if you draft templates in Word Doc, or LLM's like Chat GPT, they input special characters that cost $$$ to send via SMS.. For example extra spaces, apostrophes or hyphens that read different in Twilio.
Check the difference on this example ..we run everything through it.. hope it helps , thank me later ;)
Something as simple as this will cut your bulk SMS cost by 50%
