Why Anesthesiologists Are Harder to Reach Than Dermatologists (And What That Says About Your Email Strategy) | NPLUS Global

The scenario below is a composite built from patterns we've seen repeated across the industry — not an actual client engagement. Names, numbers, and specifics are illustrative.

A mid-size medical device manufacturer was launching a perioperative monitoring product. The target buyer list spanned several specialties: orthopedic surgeons, anesthesiologists, hospitalists, and a smaller group of pain management physicians. The marketing team built one campaign, one list vendor, one cadence, and ran it across all four groups simultaneously. It seemed reasonable — same product category, same general hospital setting, same message about improving surgical outcomes.

The orthopedic surgeons responded reasonably well. Not spectacularly, but predictably — opens happened, a handful of replies came in, some meetings got booked. The anesthesiologists and hospitalists were a different story. Opens were negligible. Replies were essentially zero. The pain management group fell somewhere in between, which only added to the confusion, because on paper their day-to-day looked closer to anesthesia than to ortho.

What Didn't Work

The first instinct, understandably, was to blame the list. The team re-verified emails, ran a fresh append, tightened the NPI-to-email matching, and relaunched. Deliverability numbers looked fine — the emails were landing. They just weren't being opened, and when they were opened, nothing happened after.

The second instinct was to blame the message. They rewrote subject lines, shortened the copy, tried a more clinical tone versus a more commercial one. Marginal movement, nothing that explained the gap between orthopedics and anesthesia.

The mistake wasn't in the list or the copy — it was in treating "specialty" as the variable that mattered, when the actual variable was how that specialty practices and who controls their inbox.

The Diagnosis

Sit with the actual working conditions of these physicians for a minute, because they're genuinely different.

An orthopedic surgeon, especially one in a private or physician-owned group, often has an individual professional inbox they check between cases, at the end of the day, or on a phone during downtime. They own their practice's communications, or close to it. Their staff might filter some things, but the physician is still a reachable individual with agency over that inbox.

An anesthesiologist, by contrast, is very often hospital-employed or part of a large anesthesia group contracted to a health system. Their working day is a sequence of procedures with almost no scheduled desk time. Many don't have a personal professional inbox they check regularly — communications route through group administrators, or through institutional addresses that get filtered by hospital IT before a human ever sees them. The physician isn't ignoring the email. In a meaningful number of cases, they never see it.

Hospitalists share a similar problem from a different angle. They rotate, they move between employers more frequently than most specialties, and their institutional email addresses often have a short shelf life relative to how long that address sits in a third-party database. A hospitalist who left a health system eight months ago may still be "current" in a list that was refreshed six months ago — which looks like a deliverability issue but is really a turnover issue specific to how that specialty is employed.

The pain management group's mixed results made sense once this lens was applied — it's one of the few specialties that splits fairly evenly between hospital-employed and independent-practice models, so the list was effectively half "reachable" and half "structurally unreachable," blended into one undifferentiated batch.

None of this is really about email as a channel. It's about practice setting, employment structure, and who has functional control of an inbox — factors that overlay specialty but aren't the same thing as specialty.

What Changed

The team stopped running one campaign across four specialties and started treating employment model and site of care as the primary segmentation, with specialty as a secondary layer.

For the orthopedic surgeons, they kept doing roughly what was working — individual outreach, direct scheduling links, physician-level personalization.

For anesthesiologists and hospitalists, they shifted the goal of email away from "get a reply" and toward "create familiarity before a human touch." Email became a supporting channel rather than the primary conversion mechanism — used to seed awareness ahead of conference contact, group-practice outreach, or a rep who could get in front of a department administrator. They also adjusted timing: batch communications sent in the narrow windows around shift changes performed slightly better than the standard "Tuesday 10am" send logic that worked fine for office-based specialties but meant nothing to someone whose Tuesday was three back-to-back procedures.

They also went back to the data itself and stopped assuming a taxonomy code told the whole story. Two physicians both coded as "anesthesiology" can have completely different reachability profiles depending on whether they're in a large single-specialty group with an admin gatekeeper, a small independent practice, or a hospital employment arrangement. Some list providers — NPLUS Global among them — build in practice-setting and affiliation data specifically because specialty codes alone don't capture this, and for these harder-to-reach groups, that additional layer mattered more than another round of email verification did.

The Outcome

Nobody turned anesthesiologists into a highly responsive email audience — that's not really achievable given how the specialty works, and any claim to the contrary should be treated skeptically. What changed was the team's expectations and how they measured success. Email engagement among the hospital-based groups moved from essentially flat to modestly better, but more importantly, the overall pipeline improved because email was doing a smaller, more honest job — warming the ground for other channels — instead of being asked to close deals it was never going to close on its own.

The bigger shift was internal: campaign planning stopped assuming specialty was the segmentation, and started asking a more useful question first — does this person control their own inbox, or does someone else stand between them and it? For some specialties, the answer to that question tells you more about expected performance than anything in the subject line ever will.
