Features
Everything You Need to Verify Emails With Confidence
Our multi-layered email verification engine checks every address at every level — from format to mailbox existence — so you can trust your data completely.
Syntax Validation
Instantly check whether an email address follows RFC 5322 formatting standards. Supports Unicode domains and catches typos before they reach your database.
MX Record & DNS Verification
Confirm that the recipient's domain has active mail servers configured and is capable of receiving email — a critical step in reducing hard bounces.
Disposable Email Detection
Block throwaway addresses from fake signups. Our continuously updated database flags temporary email providers so only genuine users enter your list.
Real-Time Email Validation
Get verification results in under 100ms on average. Perfect for validating emails at point-of-entry on sign-up forms, checkout pages, and lead capture.
SMTP Mailbox Verification
Go deeper with optional SMTP verification. We connect directly to the mail server and confirm the mailbox exists — without sending a single email.
Bulk Email List Cleaning
Upload CSV files with thousands of email addresses and get a clean, validated list back in minutes. Ideal for list hygiene before major campaigns.
Catch-All Domain Detection
Identify domains that accept every incoming email, regardless of whether the mailbox exists. Know your deliverability risk before you hit send.
RESTful Email Verification API
Integrate in minutes using our developer-friendly REST API. Full documentation, code samples in 10+ languages, and instant API key access after signup.
Dashboard Analytics & Usage Tracking
Monitor your validation history, credit usage, success rates, and deliverability insights from a clean, real-time dashboard built for teams of all sizes.
Deliverability
A Clean List Is Only Half of Reaching the Inbox
The other half is the domain you send from. PilotVerify checks your DNS and authentication, watches the Spamhaus blocklists, and turns the DMARC reports receivers already send into something you can read.
Explore the deliverability toolsClean the list
Verification strips dead addresses, spam traps and typo domains before a send, so your bounce rate stays where mailbox providers expect it.
Build the reputation
Get MX, SPF, DKIM, DMARC and MTA-STS right once, and receivers start treating your authenticated mail as authenticated mail.
Monitor inbox health
Reputation decays between campaigns. A Spamhaus listing, an expired DKIM key or a new sender spoofing you becomes an email to you, not a quarter of missing replies.
