# LeadMagic > LeadMagic turns incomplete B2B lead records into verified work emails, direct mobile numbers, company intelligence, and buying signals for sales teams, developers, and AI agents. Teams use LeadMagic through CSV upload, REST API, LeadMagic CLI, hosted MCP, chat, and integrations. Credits are deducted only for valid results. Direct REST requests use an API key in the X-API-Key header. LeadMagic CLI uses secure browser sign-in through lm login; normal CLI workflows do not use a pasted LeadMagic API key. Hosted MCP uses OAuth in the AI client and does not accept static API keys in client configuration. Every interface shares the same LeadMagic account credit balance. Last updated: 2026-09-17.

[Email Verification Glossary](https://leadmagic.io/glossary): 9 curated B2B email and deliverability terms. - [Email verification](https://leadmagic.io/glossary/email-verification): Email verification is the process of gathering evidence about whether an email address is structured correctly, belongs to a mail-enabled domain, and is likely to accept a message. A robust result includes a status and reason codes rather than a promise that every future message will be delivered. - [Catch-all email](https://leadmagic.io/glossary/catch-all-email): A catch-all email is an address at a domain configured to accept mail for recipients even when the requested mailbox cannot be confirmed. The phrase usually describes a verification result rather than proof that a particular inbox exists. It is synonymous with accept-all email in most operational contexts. - [Accept-all email](https://leadmagic.io/glossary/accept-all-email): An accept-all email is an address on a domain whose mail server accepts mail for every recipient, including mailboxes that don't exist. Because the server says yes to everything, a standard SMTP check can't prove the person's inbox is real, so verifiers label it accept-all, catch-all, risky, or unknown instead of valid. - [Email deliverability](https://leadmagic.io/glossary/deliverability): Email deliverability is the ability of a message to reach the intended recipient's inbox or another desired folder after it has been accepted for delivery. It is broader than delivery rate: a delivered message can still be routed to spam, quarantined, or placed in a secondary tab. - [Bounce rate](https://leadmagic.io/glossary/bounce-rate): Email bounce rate is the percentage of attempted deliveries that the receiving system does not accept. It is commonly calculated as bounced messages divided by messages sent, multiplied by 100. Reporting should separate hard bounces from soft bounces because they signal different problems and require different actions. - [Email finder](https://leadmagic.io/glossary/email-finder): An email finder is a tool that identifies a likely email address for a person or company from inputs such as name, employer, domain, or professional profile. A finder may use known data, email-pattern inference, and verification signals. Finding and verifying are related but distinct operations. - [Bulk email verification](https://leadmagic.io/glossary/bulk-email-verification): Bulk email verification is the process of evaluating a file or database of many email addresses in one job. The service usually normalizes inputs, checks syntax and domains, performs mailbox-level tests where appropriate, and returns a status plus supporting reason codes for every row. - [DKIM](https://leadmagic.io/glossary/dkim): DomainKeys Identified Mail, or DKIM, is an email authentication method that adds a cryptographic signature to a message. A receiving server retrieves the sender's public key from DNS and verifies that signed headers and body content have not changed in a way that breaks the signature. - [DMARC](https://leadmagic.io/glossary/dmarc): Domain-based Message Authentication, Reporting and Conformance, or DMARC, is a policy and reporting protocol built on SPF and DKIM. It lets a domain owner state how receivers should handle messages when aligned authentication fails and provides reports about observed mail using the domain. ## About And Citation - [Company](https://leadmagic.io/company): About LeadMagic, customers, security, and contact. - [Status](https://leadmagic.io/status): Live API health check, service status, and incident reporting.
