Ask any HCP platform whether their audience is verified and the answer will almost certainly be yes. The more revealing question is: verified how?
The audience a platform claims to offer is only as valuable as the processes used to verify it. And as evidence increasingly shows, those processes vary enormously across the industry.
Across the industry, the term ‘verified’ covers a remarkably wide spectrum – from a confirmed email address at one end, to full credential validation against an official medical registry at the other. The difference between these two points on that spectrum can represent 40% or more of your campaign budget.
The verification spectrum
At the lowest end, verification means nothing more than email confirmation – a user has clicked a link in a welcome email. This confirms that an email address exists. It says nothing about whether the person behind it is a doctor, or whether their credentials are genuine.
One step up, some platforms accept self-reported professional status – a user states their specialty, seniority and registration number without those details being checked against any external source. This is marginally better than email-only, but remains highly susceptible to inaccuracy. Vague classifications such as ‘probably a doctor’ – which do appear in some platform reporting – are a direct product of this approach.
At the gold-standard end, verification means something entirely different: credentials are checked against official medical registries. Automated partnerships with bodies such as the UK’s General Medical Council (GMC), Spain’s CGCOM, Germany’s Bundesärztekammer and France’s Conseil National de l’Ordre des Médecins ensure that registration numbers match the person submitting them. Discrepancies are reviewed manually. Accounts that fail verification are deleted – not retained, not reclassified, but deleted.
Why the distinction matters
The practical consequence of this spectrum is significant. Analysis of one European HCP platform revealed that out of 112,987 total accounts, only 60% (67,811) were fully validated. Of those, only 57.85% had been active within the last 365 days.
For a pharmaceutical marketer running a campaign against that database, the effective verified active reach is less than 35% of the headline figure. The CPM quoted bears almost no relationship to the CPM actually paid to reach a verified, active doctor.
The activity dimension
Verification of credentials is only one part of the picture. A doctor who was verified 3 years ago, and has not logged into the platform since, is not meaningfully reachable – but on many platforms, they remain in the database and in the reach figures.
The result is a database that reflects the actual, current, active doctor population – not a historical snapshot padded with accounts that have long since become unreachable.
The verification tier system
A clear framework for understanding audience quality distinguishes between four categories:
✅ Fully verified: email and credentials match the official registry perfectly – the only category that should be counted as verified reach
❌ Partially verified: email and professional ID exist but details don’t match exactly – falls short of full verification standards
❌ Unverified: email only, no credential validation – should not be counted as doctor reach
❌ Incomplete: no email validation – should be deleted within 30 days
Only fully verified doctors should have access to specialist pharmaceutical content. Any platform that counts partially verified or unverified accounts in its reach figures is overstating the quality of its audience.
Speed without compromise
One common concern about rigorous verification is the impact on campaign timelines. With automated registry partnerships handling the majority of verifications instantly, and manual review reserved for discrepancies, average verification time can be as low as 1 day and 15 hours. Rigorous verification and campaign speed are not mutually exclusive.
What this means for pharmaceutical marketers
The next time a platform tells you their audience is verified, ask them to be specific. What percentage is fully credential-verified against an official registry? What percentage is email-only? What are their MAU and YAU figures? What is their deletion policy for inactive accounts?
The answers will tell you whether the verification behind their reach figures is gold standard – or whether ‘verified’ is doing a lot of heavy lifting on very little substance.
