How free email verification works
Three simple steps to validate any email address before it hits your outreach sequence.
Enter the email
Paste any business email into the field above. No account, no credit card, no friction.
Real-time verification
Our engine queries MX records, runs an SMTP handshake, and scans for disposable domains and role accounts.
Get your verdict
See Safe, Invalid, or Unknown instantly — plus detailed signals so you know exactly why.
What we check
Every verification runs a full deliverability stack — the same engine powering Leadloadz lead search and API.
MX & SMTP validation
Confirms the domain accepts mail and the mailbox exists before you send.
Disposable & role detection
Flags throwaway addresses and generic inboxes that hurt deliverability.
Real-time results
Get a deliverability verdict in seconds — no batch upload required.
Catch-all & B2C detection
Identifies risky catch-all domains and personal emails for cleaner lists.
Full inbox & disabled flags
Surfaces mailboxes that are full or disabled so you avoid soft bounces.
No signup required
Use the tool instantly. Upgrade only when you need API or bulk access.
Why email verification matters
Sending to invalid or risky email addresses destroys your sender reputation, increases bounce rates, and wastes outreach budget. Email verification is the simplest way to protect deliverability and maximize ROI on every campaign.
Protect sender reputation
High bounce rates trigger spam filters. Verification keeps your domain trusted.
Save money per send
Most ESPs charge per email. Verified lists mean fewer wasted sends.
Higher open rates
Deliverable inboxes outperform stale purchased lists by 3-5x.
GDPR-friendly outreach
Verify before you store. Reduce compliance risk with accurate B2B data.
Frequently asked questions
Everything you need to know about free email verification, accuracy, and scaling to bulk checks.
Yes. Anyone can verify an email address on this page without creating an account. For bulk verification, API access, and MCP integration, upgrade to a paid plan starting at Starter.
We validate MX records, perform SMTP handshake checks, detect disposable domains, flag role accounts (info@, support@), identify personal/B2C addresses, and surface catch-all domains.
No signup is required to use this free tool. Create a free Leadloadz account if you want lead search, MCP server access, or unlimited verification through the API on paid plans.
Our 5-layer verification stack checks MX records, SMTP handshake, disposable domains, role accounts, and catch-all configuration. For most business domains, accuracy exceeds 95%. Catch-all domains and strict mail servers may return 'unknown' to avoid false positives.
Upgrade to Starter ($29/mo) or higher for REST API and MCP verify_email access. Connect Claude, Cursor, or any MCP-compatible agent for automated verification at scale.
A catch-all domain accepts email for any username, even if the specific mailbox does not exist. We flag these as 'unknown' rather than 'safe' because emails to catch-all addresses may still bounce or go unread.
Role accounts are generic addresses like info@, support@, sales@, or hello@. They are not tied to a specific person and typically have lower engagement rates. We flag these so you can prioritize personal decision-maker emails.
Yes. Paid plans include a REST API and MCP server. You can verify emails programmatically, sync results to Salesforce or HubSpot, and build automated workflows.
