Other listed prices include Proofy from $5, QuickEmailVerification from $4 and NeverBounce's pay-as-you-go option at $8 one-time. Check the current pricing page for plan terms.
Choose a practical workflow
An API can suit software-based work, while a website or browser extension may fit a browser-led workflow. Compare the access method with where you handle email addresses.
Read the documentation and pricing details before choosing, especially when you need a free plan or a paid option.
