I'm not a Rogers customer myself, but I have a couple disappointed customers who are.
I've been trying to text them from email using the email@example.com address, but it just gets returned to me. Says something about "maillynx_smartrouter: Undeliverable". The numbers are correct, as I've checked them with the customers.
I can't do the web-based texts as it wants me to register for some reason, and I don't think I can send to more than one number at once.
