To send a text from an email client, email software, or webmail to a Koodo number don't use firstname.lastname@example.org . Instead, use email@example.com . It works great every time. Can be done from your PC. Both use the same network since Telus owns Koodo however, for some reason "@msg.koodomobile.com" no longer works. I have tried firstname.lastname@example.org to numerous Koodo numbers and everyone receives my text messages.
