The same title means different things at different sizes
At a forty-person company, a Head of Operations may own tooling, vendors, process and budget. At a four-thousand-person company the same title sits inside a function, owns one slice of it, and has no route to the decision you are describing. Filtering a title across a mixed-size target market therefore returns two populations that have almost nothing in common, and a campaign written for one will read as noise to the other.
Titles inflate and deflate by market
Some industries hand out director-level titles early; others keep senior people on modest ones for years. Agencies, financial services and early-stage technology companies all title differently for equivalent work. A seniority filter applied uniformly across a mixed list will over-collect in some segments and miss the right people entirely in others.
What to use instead, in combination
- Department, so the person sits in the function that owns the problem.
- Seniority, read relative to the size and shape of that specific company.
- Role context: what the role actually covers at this employer, not what the words usually mean.
- Whether the function exists at the company at all — often the fastest disqualifier.
The most senior person is frequently the wrong one
It is tempting to aim high on the assumption that a senior contact can always delegate. In practice, senior contacts delegate to the person who was the right contact in the first place, and the message arrives second-hand and diluted. For most operational purchases the right target is the person whose week the problem lands in, which is often one or two levels below the top of the function.
The cost of getting it wrong is not the bounce
A wrong-person record usually has a perfectly valid email address, so it passes verification and counts toward a healthy delivery. It costs you in the places that are harder to measure: reply rate, sales confidence in the file, and the complaints that accumulate when people receive messages that were obviously not meant for them. Email verification confirms the address. It cannot tell you whether the person behind it is relevant.
