Primarily English speaking countries see the word "Mate" and pronounce it as "Meit" as in a partner, friend, etc. "What's up mate". In the context of Yerba Mate tea however, it is pronounced as “Yerba MAH tay” or if you’re in Argentina “Sherba MAH tay.” An easy way to remember is that it rhymes with "latte". Here's a good link if you want to never forget how to say it: https://youtu.be/xTUVOBsxqHkYou may also see mate spelled with an accent mark "maté." English speaking countries tend to spell it with an accent “maté” to lessen the confusion but in spanish this means “I killed” so I try to avoid it. I tend to write "Yerba mate" to make it easier to understand I’m referring to a Tea rather than a partner/pal/friend.
