You can define the limitation to:

Automatic alias detection

Drimify automatically detects common email aliasing tricks so the same mailbox cannot re-enter under a different spelling of its own address. When comparing a new entry against previous participations:

Capitalisation is ignored (User@example.com = user@example.com)
"+" tags are ignored for all providers (user+contest2@example.com = user@example.com)
For Gmail addresses, dots in the name are ignored (u.s.e.r@gmail.com = user@gmail.com), and googlemail.com is treated as gmail.com

The participant's email is stored and exported exactly as they typed it — the normalisation only applies to the duplicate check.

Please note that while enabling this option limits users to a single play with their email address, it won’t stop some users playing again with a different, genuinely separate email address. Where prizes are concerned, see Can I make sure each person wins only once?
