Sending custom emails via sms

Im using the task functionality to send my users daily emails. However, instead of emails, I’m sending them sms messages through the carrier’s email to text functionality. For example, I’m sending the email to

When I send a task email to any Verizon number (, the message ends with an extra blank line inserted and a ? below the blank line. This only occurs when sending to Verizon numbers and it only occurs when sending from knack. I have successfully sent email to text to other carriers without the awkward space and ? in it. I’ve also sent email to text to Verizon numbers from my email without the same awkward space and question mark.

Has anyone else had this issue? Does anyone know what’s causing it?
