The dead database: the elephant in every CRM team's room

Intuitively, the reasoning goes: if the customer doesn't open your emails, they've lost interest. Sometimes that's true. But sometimes they aren't even seeing you, and then the problem isn't content, it's infrastructure.

At my first agency after arriving in Madrid, with a client in entertainment and streaming, the problem started with a real pain: the percentage of the database in spam was high, they pointed it out in every meeting, and it was putting the account itself at risk.

In one of those famous crisis-turned-opportunity moments, going through options and ideas, we reached the question: do they really not want us, or are they simply not seeing us? In "Recapturing Lost Customers", Thomas, Blattberg and Fox argue that most companies treat reactivating inactive customers as a repeat of their acquisition strategy, without first diagnosing why those customers left. In plain terms, every silence is read as the same cause.

Understanding the limitations of User.com as a CRM, we built the plan from there. The idea was a hook email with an eye-catching subject line, selling nothing yet, just generating curiosity. Inside, a real instant prize: products discarded from past events for the client's series, merchandise that would otherwise have gone in the bin and that we would use as an incentive. Merchandise that people appreciate and even collect in other contexts.

The email's mechanics were designed around a key restriction of the email clients themselves: you couldn't see what the prize was without clicking the CTA, and that CTA only activated once the email left the spam folder. In other words, to get something for free, the user had to do, without knowing it, exactly what we needed: mark us as a trusted sender and take us out of that folder.

The result was the recovery of 22% of a base that was already considered lost. And it wasn't an isolated effect: the impact was sustained afterwards with +102% subscriptions, +24% CTR and a +30% uplift in sales, once those contacts were back in the normal communication flow.

What I take from that experience is that the "dead database" tends to be the elephant in the room for any CRM team: everyone sees it, nobody points to it, and it's more comfortable to walk around it than to ask it directly what's wrong. Before accepting the easy diagnosis, it's worth doing exactly that, addressing the elephant: asking the base why it doesn't respond, instead of assuming it has nothing left to say.
