Outbound engine

Why list quality matters

A poor list causes most outbound problems at once: bounces that hurt reputation, irrelevant messages that earn spam complaints, and wasted sending capacity.

  • Your bounce rate is high or your platform warns about invalid addresses
  • Lists were bought or scraped and nobody knows how current they are
  • Contacts are the wrong role, size or industry for what you sell
  • The same people appear several times across campaigns

Deliverables

What you receive

Scope is agreed in writing before work starts. You can take the whole list or only the parts you need.

Process

How a list is built

You get a short update at each stage: what was done, what we found and what happens next.

  1. Define

    Agree the ideal customer, exclusions and the fields your copy will need.

  2. Sample

    Build a small sample first so you can confirm the targeting is right before the full list.

  3. Build and verify

    Source, enrich and verify the full list, then remove duplicates and exclusions.

  4. Deliver

    Hand over the file or import it, with a summary of counts and verification results.

Data-tool subscriptions are usually held in your account so the data and licence stay with you.

Data quality and responsibility. Verification greatly reduces bounces but cannot make any list perfect: people change jobs, and some servers accept every address. We label “catch-all” and risky results instead of hiding them. We collect business contact data only, and you remain responsible for how it is used under the rules in your markets.

How fresh is the data?

Data tools vary, so we verify every address close to the time it will be used. If a list sits unused for months, we recommend verifying it again before sending.

What does “catch-all” mean?

Some company mail servers accept mail for any address, so a verifier cannot confirm whether a specific person exists. We flag these separately so you can decide whether to send to them, usually in small volumes.

Can you clean a list we already have?

Yes. We can verify, de-duplicate and segment an existing list, and tell you which sources are producing the most invalid addresses.

Do you sell lists?

No. Each list is built for your criteria and your use, and the tool licences generally belong to whoever holds the subscription.
