My name is Boris and I am Support Representative of CS Networks
It is possible to send SMS from email.
You just need to configure the email client you have. Ex. Microsoft Outlook
All you need to do is in "To" field put the recipients number with @domainyouwant.com. In "Subject" field you put the sender name. Note: I have not tried sender name with spaces and special characters.
For any info or question contact me via pm or however is easier for you.
