Swiss people have been able to vote via mail-in vote since forever and there were never any instances of large-scale fraud that I know of. It's true that in-person voting is safer. If you mail in your ballot, nobody can verify that you were truly alone and weren't coerced into giving your vote. And of course, it's not rare for e.g. a child to fill out the ballot for its senior parent etc. But it's still hard to commit large-scale fraud, as you'd need to be in control of the mail delivery.
