What is Profile Enrichment, and what does it find?

More than 90% of the profiles Bread & Butter researches match the right person. That takes an enormous amount of work behind every single profile, because putting a name, a role and a company to an email address is far harder than it looks. People change jobs, share inboxes, register on someone else's behalf and use addresses that read like another person's name, and every source that holds information about them is partly out of date. The industry's own tests show how hard it is:

  • Even the best-known contact databases get a large share wrong. In a test of 50,000 contacts exported from three of the best-known contact databases in May and June 2026, only 65% to 71% of the email addresses could be confirmed valid, and 9% to 13% were invalid outright. (BounceZero, 2026)
  • Email-finding tools miss often. Across 15 email-finding tools tested on 20,000 contacts with real sends, about 1 in 6 of the addresses they returned was wrong on average, either bouncing or on the wrong company's domain. The weakest got close to 1 in 3 wrong. (Dropcontact, 2025)
  • Personal addresses are harder still. Across five data providers and 2,354 contacts whose personal addresses were already known, a personal email could be confirmed for only 43% of attempts. (Clay)
  • A personal address rarely leads to a work identity. Published benchmarks put the success rate for matching a personal address, such as Gmail, to the person's work identity at 12% to 28%, against 80% to 98% for a work address. (Crustdata, 2026)
  • Guarantees are narrower than they sound. One of the largest contact databases offers a 95% accuracy guarantee, but it covers only which company a person works for. (Amplemarket, 2026)
  • And all of it goes stale. At least 23% of an email list decays within a year. (ZeroBounce, 2026)

That is why Profile Enrichment never trusts a single source. The moment someone raises a hand on your website, AI research agents check several research services against each other: professional networks, corporate databases and company profiles, the company's own website, the press and the open internet. They compare what each one says about the person and keep the match the evidence supports best. When the evidence isn't conclusive, they write nothing rather than something that might not be true.

A bought list gives you a name, a title and an email address that hundreds of other companies bought too, and tells you nothing about whether that person has ever heard of you. Profile Enrichment starts from the other end. Someone has already been on your website, read your pages and raised a hand, and the research is cross-referenced into one profile of the person and the company behind them.

A profile in Bread & Butter is therefore two things joined together: the User Journey, recorded from the very first visit, and Profile Enrichment, researched the moment an email address arrives.

Before the hand goes up, every visit is already recorded. When an email address arrives, a work address or a personal one such as Gmail, Profile Enrichment researches the person (role and seniority, career path and highlights, location) and the company (what it does and recent news, who else works there, warm connections), and runs again on every return.

In short: More than 90% of Bread & Butter's enriched profiles match the right person, against an industry where even the best-known contact databases get a large share wrong. It takes real work behind every profile: Profile Enrichment checks several research services against each other, keeps the best-supported match, and writes nothing when the evidence isn't conclusive. When the research finds a clear match behind an address, it puts that person's name forward; you can choose to keep the names typed into your forms instead. Every profile is the User Journey, recorded from the first visit, plus this research, which runs again whenever the lead returns to your site. A bought list is the same contacts everyone in your category is emailing; an enriched profile is one person who came to you, with their whole journey and real research behind them.

What the User Journey records

The User Journey starts on the first visit, before anyone has told you anything about themselves. It records every page viewed, the source and campaign that brought the visit in, each return visit and the gaps between them.

One tracking code covers as many web properties as you run, so someone moving between your sites stays a single profile with a single journey instead of splitting into separate records you would have to piece together later.

By the time an email address arrives, the journey is already sitting there waiting for it. That is why a new lead in Bread & Butter does not start as a blank record: it starts as a history of everything that person read before they were willing to tell you their name.

What Profile Enrichment researches

Profile Enrichment runs the moment an email address is captured. It doesn't need to be a work address: a personal address, Gmail included, is researched the same way, because the research starts from the person, not the domain. AI research agents take the address and cross-reference it across several research services, professional networks, corporate databases and company profiles, the company's own website, the press and the open internet, then build the profile out around it.

The person

  • Email address, validated through a multi-step check as a deliverable account before it is recorded
  • First and last name. Not every form asks for a name, and many people skip the fields or type something that isn't theirs, so when the research finds a clear match behind the address, it puts that person's name forward. If you'd rather keep the names typed into your forms, your account can be set to never replace them, and, when no name was entered, to propose one or leave it blank
  • Current role or position, with seniority level, which is what lead routing keys off
  • Location and local city events, which gives a rep a better opening than the weather
  • Profile summary, a narrative account of their professional background rather than a list of fields
  • Profile highlights, meaning specific milestones such as authored articles, awards or speaking engagements

The company

  • Company summary, a high-level overview of the organization
  • Company social accounts, with direct links to the corporate LinkedIn and X (Twitter) profiles
  • Company highlights, covering buying triggers and organizational milestones
  • Company recent news, from ongoing monitoring of the company's presence in the press
  • Company events, including webinars, product launches, conferences, awards and industry recognition
  • Company employees, a map of internal stakeholders so your rep can see who else might be a champion
  • Potential connections, the warm paths into the account through shared professional circles

Every enriched profile gets the full picture. There is nothing to switch on and nothing extra to buy.

How accurate is it?

More than 90% of enriched profiles match the right person. The research starts from nothing more than an email address, and an email address doesn't always belong to the person who used it, so the rest can go wrong in a few familiar ways:

  • An assistant registers for someone else. An executive assistant or an office administrator fills in a form on behalf of a colleague, with their own address or a shared one.
  • A shared address. A team inbox, a family address or a front-desk address is used by more than one person.
  • A different name on the form. Someone registers under one name with an address that belongs to, or reads like, another.

These happen most often on company domains, where one address can stand for a role, a team or the person who manages someone else's inbox, and different sources can point to different people.

That's why the research never relies on a single source and leaves out what it can't confirm rather than guessing. When our research and a corporate database disagree about who is behind an address, our research should win. It's a delicate balance: a database is often right, and research can find a namesake too, so the two are weighed against each other rather than either one being trusted blindly. The email address the person typed always stays exactly as they gave it.

How it compares with a bought list

A contact database sells the same records to everyone in your category, which is why one prospect receives eleven near-identical emails in a month. The person on the list never asked to hear from you, the title is often a year out of date, and nothing on the record says whether they have ever looked at what you sell.

An enriched profile is the opposite on every count. The person came to you and raised a hand, so their email address is their permission to be known. The research is done now, not when the list was compiled, and it runs again every time they return. And the profile sits next to the journey, so the rep sees what this person read, how often they came back and which campaign brought them, alongside who they are.

How the research feeds Focused Score and your ideal customer profile

The research isn't only for the rep to read. Once someone raises a hand, what Profile Enrichment finds feeds their Focused Score alongside everything they did on your website: their role, their career path, the company they work for and who they're connected to. A deeply engaged visitor who turns out to be a student isn't a buyer, and a perfect-looking profile who left after four seconds isn't one either; the score reads both halves together.

The same two halves build your ideal customer profile. It starts from your first Engaged Leads, sharpens as contacts move up your lead stages, and learns most from every deal you mark Won/Closed, when it looks back over everything that person did and who they turned out to be. There is nothing to set up and nothing to adjust: it starts on its own and keeps learning the longer it runs. That profile is what the lookalike prospects are matched against, so each batch that arrives is closer to the people who already bought. See How Bread & Butter finds lookalike prospects from your best closed deals.

The research re-runs on a return visit

Enrichment is not a snapshot frozen on the day of capture. When a lead comes back to your website, the research runs again against the same profile.

This matters because the facts move. People get promoted, change employers, and end up at companies that have just raised a round or shipped something. A lead who first appeared eighteen months ago and has just returned is not the same prospect as the one in your original record, and the profile your rep opens reflects the current version rather than the historical one.

A return visit is also the moment the information is worth the most. It is the clearest signal you get that an account has gone live again, which is exactly when a rep needs the research to be current.

Where the results show up

The enriched profile sits on the lead's record next to the User Journey, so the research and the behaviour are read together rather than in two different places.

From there it feeds the surfaces your team works in. The Intelligence Brief is the per-lead write-up a rep reads before making contact, delivered where the team already works: the CRM, Slack or the inbox. The Intelligence Stream is the running feed of what is happening across your leads. The Nurture Action Queue prioritizes the Engaged Leads worth acting on, and enrichment details are available as selectable items inside Nurture drafts so a rep can pull a specific highlight or news item straight into a message.

For industries that will not accept anyone emailing on a rep's behalf, the Intelligence Brief carries the first draft and the rep sends it from their own CRM.

Who owns what

Your User Journey, and the first-party data about how people behave on your own website, belongs to you. We do not resell it.

The enrichment profile is a different thing. It is researched from professional networks, corporate databases, company profiles and the open internet, so it is not your data. You get the benefit of that research on every lead you capture, and it travels with the profile inside Bread & Butter, but the underlying profile is not yours to own.
