Most outbound gets the account right and the person wrong. You define a sharp ICP, build the list, and then write a single message aimed at the company. But a company does not read email; people do, and the people inside one account want opposite things.
ICP picks the account, personas win the person
The ICP describes the company worth targeting. The persona describes the human inside it: their role, their goal, the objection they will raise first. You use the ICP to choose who to reach and the persona to decide what to say. Blur the two and you write to an average person who does not exist.
Three messages, same account
Take one ICP and split the buying committee into the few personas that matter, usually the economic buyer, the champion who feels the pain daily, and the blocker who has to sign off. Each gets its own angle: outcome and risk for the buyer, time and frustration for the champion, control and safety for the blocker. Same proof, three doors in.
Where it plugs in
This is also how paid and outbound reinforce each other: matched audiences and ABM surround the whole committee, while your sequences speak to each persona directly. Precision on the person is what turns a good list into replies.
Common questions
What is the difference between an ICP and a persona?
An ICP describes the ideal account or company to target; a persona describes an individual person within it. You target the ICP and write to the persona.
Why split personas in outbound?
Because one account contains people with different roles and motivations, so a single message fits none of them well. Splitting the buying committee into a few personas lets each get an angle that actually resonates.
