Use the result well

A clear answer, with the assumptions visible

These recommendations turn the result into an operational next step without hiding the inputs behind a score.

  1. 1

    The message fits in one segment with the variable room included.

  2. 2

    The text stays in the lower-cost GSM-7 alphabet.

  3. 3

    Send a test with the longest expected client name before a bulk send.

How this tool works

  1. Check every character against the GSM-7 alphabet.
  2. Use the correct single and joined-message limits.
  3. Multiply segments by recipients and cost per segment.
