Detect disposable and temporary emails
Block throwaway addresses at signup so trials, discounts and free tiers go to real users — not bots farming freebies.
Disposable email providers give users a temporary inbox that self-destructs in minutes. People use them to claim free trials repeatedly, dodge verification, and abuse referral or coupon systems — inflating your numbers while costing you money.
The Email Validator recognizes disposable and temporary domains and flags them so you can reject or step up verification at signup. It also catches role accounts and dead domains in the same pass.
Use it inline on registration, or batch-check an existing user table you suspect is polluted — and slice the results with Text-to-SQL if you need to.
