Find verified email addresses: verified at send time, not once at purchase.
B2B data decays 2-3% a month. The only verification that holds is the one that happens when you send.
Know which one your tool sells you
Many tools guess from name-and-domain patterns and market it as verification:
- Verified: confirmed live at SMTP level, ideally the moment you pull or send.
- Guessed: first.last@company.com assembled and hoped; the leading bounce cause.
- The tell: a tool that returns an address for every lookup is guessing.
- The gap: vendors claiming 95-98% accuracy whose users report 20-30% bounces.
The thresholds that protect your domain
Bounces are not wasted sends; they are a tax on every send after:
- Under 2%: the safe hard-bounce line; above ~3% you read as a spammer.
- 4-8 weeks: typical reputation recovery after one bad list.
- The decay clock: 2-3% of the list goes stale monthly; verification is a moment-in-time fact.
- The fix: verify at send time + bounce auto-pause, so bad data stops itself.
Catch-alls and role addresses
Two address types need special handling in every list:
- Catch-all domains: accept everything, so no tool fully confirms the mailbox; treat as medium-risk.
- Role addresses: info@, sales@, support@ reply rarely and complain often; filter them out.
Ask where the data actually lives
Sourcing decides how fast accuracy decays and who is accountable:
- Owned: collected and re-verified by the provider you pay; freshness has one owner.
- Rented: resold from third parties, rarely refreshed, nobody accountable.
- Run the 100-record test: on your exact ICP before any contract; it beats every accuracy claim.
The phone side matters as much
Calls on verified mobiles are the highest-connect touch in most sequences:
- Demand mobiles, not switchboards: coverage differs 10x between providers.
- Salesgear: 95% direct-dial accuracy across 800M+ owned contacts, wrong numbers swapped free.
- Verified on request: each email re-checked the moment you pull it, which is what holds bounces under 2%.
Finding verified email addresses, answered
How do I find verified email addresses?
Use a provider that SMTP-verifies each address at the moment you pull or send it, not one that pattern-guesses from name and domain. The test that settles any vendor claim: pull 100 contacts matching your exact ICP, bounce-test them, and reject anything over 5% hard bounces. Verification timing matters because B2B data decays 2-3% every month as people change jobs.
What is the difference between verified and guessed emails?
A verified email has been confirmed live and accepting mail via SMTP-level checks. A guessed email is assembled from a pattern (first.last@company.com) and may not exist. The tell: a tool that returns an address for every single lookup is guessing, and 'accuracy' claims that cover guessed data are marketing. Some vendors' users report 20-30% real-world bounce rates behind 95%+ accuracy claims.
Why do bounces matter so much?
Keep hard bounces under 2%. Above roughly 3%, mailbox providers treat you as someone mailing addresses you do not know, your domain reputation drops, and even your valid sends start filtering to spam. One bad list can tax deliverability for 4-8 weeks after you stop using it.
What are catch-all and role-based addresses?
A catch-all domain accepts mail for any address, so verification cannot fully confirm the individual mailbox; treat catch-alls as medium-risk and send to them from warmed inboxes. Role addresses (info@, sales@, support@) belong to teams, reply rarely, and attract complaints; filter them out of outreach lists entirely.
Can I get phone numbers along with verified emails?
The strongest providers pair both. Salesgear couples verified emails with 95% direct-dial accuracy across 800M+ contacts, with wrong numbers replaced at no charge. Since calls on verified mobiles are the highest-connect touch in most sequences, the phone side of a data provider matters as much as the email side.
