E-Gift Card

A friend of mine is currently suffering a loss, and I was thinking of sending them an E-Gift card for Insomnia Cookies. However, I do not have their email. I don’t really want to ask them for it during this time, I’d rather it just be a surprise if I can help it. If I put my email in for the E-Gift Card, can I somehow send it to them over text? Or is it really email only
