A foreign student emailed me and asked if I could share a copy of my article. Yes or no?

New faculty here. I published a journal article last year and it was well-reviewed. Yesterday a student located in an underdeveloped country wrote to me and explained that she was finishing her thesis and found my publication highly relevant to her research. However, it was paywalled and her library doesn’t have access to it. Purchasing a PDF version on the official website would cost more than her monthly living allowance. In this case, should I just send her a PDF version of my article or not? (Also, she emailed from her private Gmail account rather than a school email ending in “.edu” so idk)
