Reckon App | Verify Emails - Improve Deliverability

# Reckon Real-time email verification API for developers and small teams. Reckon checks whether an email address is valid and deliverable before it enters your system — at the point of signup, form submission, or API call. Single-address, real-time verification only. No bulk list processing. ## What it does - Validates syntax (RFC standard), including plus-address detection - Checks domain and MX records - Detects disposable/temporary email addresses - Detects role-based addresses - Identifies accept-all (catch-all) domains - Verifies mailbox existence via SMTP - Returns a clear top-line determination with additional context - If Reckon can't return a clear answer, you don't pay for that check ## Who it's for Soloprenuers and small teams who need to stop bounces at the source. Common use cases: SaaS signup flows, lead capture forms, CRM data quality, cold outreach list cleanup. ## Pricing Subscription plans with monthly credits included. No credit card required for trial. Credit rate decreases at higher tiers. - Starter: $12/mo — 1,000 credits @ $0.007 each - Standard: $18/mo — 2,000 credits @ $0.0065 each - Growth: $35/mo — 5,000 credits @ $0.006 each - All plans: optional overage spending with caps Credits expire at the end of each billing cycle.
