Messaging - SMS Segments Calculator

SMS Messaging is a powerful way to send information directly to your guests, bypassing email, with automated templates and triggers.

However, it's important to create clean and concise SMS messages so that you aren't billed a lot of money each month as OwnerRez fires out messages on your behalf.  We bill you per segment, not per message, so it's important to know what a "segment" is.

Use our Segment Calculator, shown below, to see the details of your message so that you know how special characters and emojis affect the overall length and segment count.  Copy/paste your message into the below box, or just start typing, and you'll see the calculator adjust as you type.
