Targeting & ICP
What Is an Ideal Customer Profile (ICP)?
An ideal customer profile describes the companies most likely to buy, get real value from the product, and stick around, described in specific, filterable terms like industry, size and business model, not a vague sense of "our best customers." For direct mail, it matters more than in most channels, since every name on the list has a real cost attached to reaching it.

The short definition
An ICP is a description of the type of company that gets the most value from what you sell and is the most likely to actually buy it. It's built from real characteristics, industry, size, geography, business model, not aspiration. A company you'd like to have as a customer isn't automatically a good ICP fit if it doesn't share the traits of the accounts that actually convert and succeed.
ICP vs buyer persona
These two get conflated often, but they answer different questions. The ICP answers "which companies should we target." The buyer persona answers "who inside those companies makes or influences the decision, and what do they care about." A direct mail campaign needs both: the ICP determines the list, the persona determines who at each company receives the piece and what the message should emphasize.
What actually belongs in an ICP
Firmographic traits, industry, employee range, revenue band, geography, business model, form the backbone. Behavioral or situational signals, active hiring, a recent funding event, a known technology in use, can sharpen it further where that data is available. The test for any criterion is whether it has a real, explainable relationship to whether a company would buy and succeed as a customer, not just whether it's easy to filter by.
Where a good ICP comes from
The strongest starting point is your existing customer base: which accounts converted fastest, which ones expanded or renewed, which ones churned or never got value. Patterns across that group, more than any assumption about the market, tend to produce an ICP that actually predicts good-fit accounts rather than a list of characteristics that sound reasonable but don't hold up.
Frequently asked questions
Related but more specific. A target market can be broad, "mid-market logistics companies." An ICP narrows that down to the specific traits that predict a good fit within that market.
As few as actually explain buying behavior. Extra criteria added because the data is available, rather than because it predicts fit, usually make the list harder to reason about without making it more accurate.
Not necessarily. A company selling into multiple distinct segments, for example both mid-market and enterprise, may reasonably have more than one ICP, each with its own criteria and messaging.
Periodically, especially after enough new customer data accumulates to check whether the criteria still predict good-fit accounts. An ICP built once and never revisited tends to drift out of date.
Account value matters more, since every name on a mail list has a real cost attached. A general marketing ICP can afford to be looser than one built specifically for a physical channel.

How Yotru turns your ICP into a target list
Once you've defined the firmographic traits and account value that describe your ICP, Yotru uses that definition to build the actual mailing list, filtering to companies that match and, within them, identifying the right contacts to receive the piece. The ICP tells us who belongs on the list; from there we handle turning it into a real, personalized campaign. .
