A simple way to check and validate UK address data.
OptiMail validates every address against the live Royal Mail PAF, catches gone-aways before they cost you, and flags customers who've moved. Plugs into your checkout, your CRM, or your data flow.
Pay only for what works
Address checks are charged per record. Mover and gone-away flags are charged only when we find one. No flag, no fee.
Live in minutes
Three-step setup, email verification, Direct Debit, and you're validating. No procurement cycle.
Use what you need, when you need it
