will older guests be okay with online bridal shower invitations??

I’m helping plan a bridal shower for my best friend. She’s quite traditional, and her mum cares a lot about these kinds of things. Most of the guests are in their 30s, but some are 60+ and live in different cities, so paper invites are a lot of work and money. Is it normal to send digital invites for a bridal shower now, or do people still expect paper? If you went with digital, did anyone have an issue with it? Or how can I create invites that look nice enough for more traditional guests?
