DeBounce

DeBounce is an affordable email validation service that removes invalid, disposable, spam trap and deactivated addresses from your lists. It is a favourite of budget-conscious cold email senders because its prices are among the lowest available.

Standard verification uses one credit per email, and DeBounce offers add-ons for harder cases. Catch-all validation costs 10 credits per address and tries to resolve contacts on domains that accept all mail, and data enrichment costs 20 credits per successful match. It is also fast: DeBounce says it can process 10,000 emails in about 10 minutes and 100,000 in under two hours. A real-time API and form widget help stop bad addresses at signup.

DeBounce suits freelancers, agencies and small teams that verify often and want good results without paying premium rates.

New accounts get 100 free credits with no card required. Credits never expire and there are no monthly payments. Packages start at $10 for 5,000 verifications, and the price per email drops to a fraction of a cent at higher volumes.
