As answered by people managing Proofy and MockServer.
Proofy's answer
Proofy uses a multi-layer email verification process rather than relying on a single validation signal. It checks email syntax, domain and DNS configuration, MX records, SMTP and mailbox-level signals, disposable email addresses, catch-all domains, role-based addresses, mail-provider data, and additional risk indicators. Results are classified as Valid, Invalid, Risky, or Unknown, helping businesses make better decisions before sending. Proofy supports single verification, bulk email list verification, and REST API workflows in one platform.
Proofy's answer
Proofy is designed for businesses that need reliable email verification without unnecessary complexity. It combines multi-layer verification, bulk list cleaning, and API-based validation with straightforward pricing and high-volume processing. Credits do not expire, duplicate addresses are not charged, and Unknown results are not charged. This makes Proofy a practical option for marketers, sales teams, SaaS companies, agencies, and developers who need predictable costs and flexible verification workflows.
Proofy's answer
Proofy is built for email marketers, sales and RevOps teams, SaaS companies, developers, agencies, lead-generation teams, and businesses that manage large email databases. It is especially useful for organizations that need to clean email lists before campaigns, validate leads before they enter a CRM, verify signup addresses in real time, or integrate email verification directly into applications and backend systems.
Proofy's answer
Proofy was created to make email verification simpler, more scalable, and more transparent for businesses working with email data. The platform evolved around a multi-layer verification approach that combines technical validation, mailbox-level signals, bulk processing, and API access. Its focus is helping businesses reduce invalid and risky email data while keeping verification workflows straightforward and cost-efficient.

I've just found out MockServer and it looks awesome 🤩 so I wanted to check it out repeating the steps of my previous demo WireMock Testing which (as you can expect) uses WireMock, another fantastic tool to mock APIs. - Source: dev.to / over 4 years ago
