How verification works

Verified before you send, not after you bounce

Most contact databases sell you a static list that ages the moment it's built. Lakewave verifies at the moment you search.

1

Logic base matching

Cross-references known email patterns and domain structures to generate the most likely address for a given contact and company.

2

MX record validation

Confirms the domain's mail servers actually exist and are configured to accept mail, filtering out dead or misconfigured domains immediately.

3

Probe confirmation

Performs a safe server-level check against the actual mailbox without sending an email, confirming the address is live before it ever reaches your outreach.

Confidence, not guesswork

Every contact gets a star rating

Set a minimum confidence threshold — like 4 stars and up — so you never waste a send on an uncertain address.

★★★★★ Confirmed mailbox, verified today
★★★☆☆ Valid domain, pattern-matched
★☆☆☆☆ Unverifiable, excluded by default
FAQ

Questions, answered

How is Lakewave's email verification different from a bounce check?

A bounce check only tells you after you've already sent. Lakewave verifies before you send through a multi-step waterfall — logic base matching, MX record validation, and probe confirmation — so you catch bad addresses before they ever hit your sender reputation.

What is a confidence star rating?

Every contact gets a 1-5 star rating based on how confident the verification waterfall is in that email address. You can set a minimum star threshold so you never send to a low-confidence contact.

How often is contact data refreshed?

Contacts are verified at the time you search rather than pulled from a static, aging database, so job changes and email updates are reflected immediately rather than months later.

Does verification hurt my email sender reputation?

No — verification happens before any outreach email is sent, using MX validation and probe methods designed not to trigger spam flags, so your sending domain's reputation stays protected.

Stop sending to guesses.
