Verify550
Email and phone number verification service
Verify550 is an email and phone number verification service that screens contact lists to remove hard bounces, bots, spamtraps, role and catch-all addresses, disposable accounts, complainers, and other low-quality entries. Lists can be uploaded to the platform or connected through integrations, and the cleaned list can be downloaded afterward.
The service includes email verification, phone validation, and a real-time verification API with documentation, plus integrations with email service providers, e-commerce platforms, CRM systems, and search tools. Checks cover syntax, SMTP validation, roles, catch-alls, disposables, bot activity, spamtraps, and litigator patterns.
Verify550 is aimed at performance marketers, affiliate networks, and bulk senders. Pricing is credit-based, with pay-as-you-go one-time credit packs and monthly subscription plans whose rates vary by credit volume; credits can be applied to email or phone verifications. A free list analysis is offered, and higher volumes can be quoted directly.
