Clean data and low bounce rates — the thing that keeps your domain alive.
Verification is not housekeeping. Bounce rate is a signal mailbox providers use to decide whether your domain deserves the inbox, and a single unverified campaign can undo months of careful warming. It is the cheapest insurance in outbound and the most commonly skipped.
The problem
Providers read a bounce spike as a sign you are mailing a purchased or stale list. The penalty lands on the domain, not the campaign, and it outlives the mistake.

Catch-all servers accept everything, so a verifier returns 'valid' and the mail still goes nowhere. Treating catch-alls as clean is how a list passes verification and fails anyway.
Lists are checked at import and never again. With decay running continuously, a list verified in March is a liability by September.

What we do
The cheap eliminations before anything expensive runs: malformed addresses, dead domains, missing mail records.
Mailbox-level checks run through more than one provider, because verifiers disagree more often than their marketing suggests.
Catch-all domains are separated into their own risk tier and sent to at low volume from a dedicated pool, so an unknown never threatens your main sending domains.
info@, sales@, known trap patterns, previously bounced records, unsubscribes and current customers all stripped before a campaign starts.
Standing re-checks before each cycle, so decay is caught before it becomes a bounce rate.
What you get
How we’re different
You get an expected bounce figure with the cleaned file. If it is above target we fix the list rather than launching and hoping.
They are never mixed into your primary sending pool. This one decision prevents most avoidable domain damage.
Opt-outs, current customers and live opportunities are blocked at the sending layer. Nobody gets prospected by us while your AE is closing them.
Questions we get
Most tools do a basic syntax and domain check. That catches obvious errors and misses catch-alls, traps and role accounts — which are the ones that actually hurt you.
Sometimes, carefully. Plenty of legitimate mid-market Indian companies run catch-all servers, so excluding them entirely can remove a chunk of your market. We mail them at low volume from separate infrastructure and watch engagement closely.
Before every campaign cycle, and no less than quarterly for a list in active use. With decay compounding monthly, anything slower means you are sending to records you already know are questionable.
Where the numbers come from
Figures are industry benchmarks published by third parties, cited so you can check them. They describe the market, not a promise about your results.
Send us a sample. We'll verify it, forecast the bounce rate, and show you what would have failed.
