Why finding work emails in bulk is harder than it looks
You have a list of people you want to reach. Maybe it's the attendees from a conference, the heads of marketing at 200 companies that just raised money, or a spreadsheet a colleague handed you with names and company names and nothing else. You can't do anything with it until you have a way to contact each person.
Finding one work email by hand is tedious but possible. You guess that the format is first name dot last name at the company's domain, try it in a verification tool, and move on to the next one. Doing that for 300 people takes days, and the guesses are often wrong. Companies use different formats, people go by nicknames, and two people at the same company can share a name.
Email finder tools exist for exactly this. They hold large databases of work addresses and check whether an address can receive mail. The trouble is that no single source has everyone. A tool that finds 60 percent of your list leaves you exporting the misses, uploading them to a second tool, and stitching the results back together. Then you still have to decide what to do with the addresses that come back uncertain.
That's a job an AI agent handles well, because most of it is careful, repetitive judgment: cleaning up the list so each row can be looked up, trying another source when one misses, reading each verification result, and deciding what's safe to send. Kite is an AI marketer. It researches your business, builds a growth strategy, and ships the work that brings you new customers. Finding email addresses for a prospect list is one of the jobs it does every day.
How Kite finds work email addresses for your whole list
Kite starts with whatever list you have. You can paste names and companies into the conversation, point Kite at a Google Sheet, or ask it to pull a list from your connected CRM. You can work with Kite in your browser or in Slack.
First, Kite makes sure every row can be looked up. An email lookup needs a person's full name plus their company's website domain, or a link to their LinkedIn profile, so Kite fills in what's missing and checks that each person still works where your list says they do. Then it sends the whole list through its built-in email finder, which searches several data sources one after another and passes the people one source missed on to the next.
Every address that comes back gets checked, and Kite labels each one with how confident you can be that it will reach the person. Finally, Kite delivers the list where you'll use it, with the label and the source beside every address, and tells you who it couldn't find and why.

Get each person on your list ready to look up
An email lookup only works when it knows exactly who it's looking for, so Kite's first job is to give every row a name and a company website, or a LinkedIn profile link. A name and a company name alone isn't enough. "Sam Patel at Acme" could match several companies called Acme, and the lookup needs the domain, such as acme.com, to search the right one.
When your list has company names without websites, Kite researches each company and adds its domain. When a row has only a first name, or a LinkedIn link and nothing else, Kite works with what's there and fills in what it can from the person's public profile.
Kite also checks whether each person still holds the role on your list. A list from last year's conference can be full of people who have since changed jobs, and finding the address at their old company wastes the lookup and bounces later. Kite confirms each person's current title and employer from their public profile or the company's own website. When someone has moved on, Kite flags the change, and it can find whoever holds the role now if you want that person instead.
If you don't have a list yet, Kite can build one from your ideal customer profile. That work is covered in Build qualified B2B lead lists.
Look up the whole list in one pass
Kite finds work emails for up to 1,000 people at a time, and you don't need an email finder subscription to do it. The finder is built into Kite. It tries each person against one email data source, then passes everyone that source missed to the next one, and keeps going until it has tried every source it has. A person who isn't in the first database often turns up in the second or third.
The lookup runs in the background, so a list of several hundred people doesn't hold up the conversation. Kite tells you when the results are ready.
Two rules shape what comes back. First, Kite only returns addresses a data source actually found. It never builds an address by guessing a pattern like first name dot last name, because a guessed address looks exactly like a real one until it bounces. Second, Kite only keeps work addresses. If a source returns someone's personal Gmail or Outlook address, Kite leaves it out and tries the next source for a work address instead.
If your team already pays for an email finder such as Hunter or Findymail, you can connect it and ask Kite to use that account instead, or to use it alongside the built-in finder for the people the first pass missed.

Check every address before anyone sends to it
Finding an address isn't the same as knowing it works, so Kite checks every address it finds and labels each one. The check asks the company's mail server whether the mailbox exists, without sending anything to it. The result is one of four labels:
- Verified. The mailbox exists and accepts mail. These are the addresses you can send to with the most confidence.
- Catch-all. The company's mail server accepts mail for any address at its domain, so the check can't tell whether this particular mailbox is real. Many small companies set up their email this way.
- Risky. The check returned a warning, or the data source had only weak evidence for the address.
- Unverified. The check couldn't reach a verdict, so Kite keeps the status the data source reported.
When a check shows that an address can't receive mail, Kite marks it invalid. When a data source flags an address as a spam trap or a do-not-mail address, Kite holds it back and looks for a different address for that person.
The labels matter most at smaller companies. In Kite's lookups, roughly half of the addresses found at small companies come back catch-all or unverifiable, because so many of those companies accept all mail at their domain. If you only want verified addresses, tell Kite, and it will look up about twice as many people as you need so the verified list still reaches your target. If you're happy to send to catch-all addresses, Kite keeps them in the list with their label so you can make that call.

Put the finished list to work
Kite delivers the list wherever you'll use it next, with every person's verification label and the source of each address beside their details. You get one row per person with their name, title, company, LinkedIn profile, and work email.
You can ask Kite to:
- Update your CRM. Kite creates or updates the contacts in a connected CRM such as HubSpot, Salesforce, or Attio, with the new email on each record.
- Fill in a spreadsheet. Kite writes the results to a connected Google Sheet or gives you a CSV file to download.
- Start the outreach. Kite researches each person's company, writes an email for each one, and sends the campaign from your team's Kite address or a connected email product once you approve it. It then reports which messages were delivered, which failed, and who replied.
Before a list feeds a send, Kite removes anyone your team has recorded as opted out, so a new list doesn't email someone who already asked you to stop.
Kite also tells you plainly about the people it couldn't find. Each one is marked with the reason, such as no source having an address for them, or the only address found being a personal one. A list of 300 that comes back with 240 addresses and 60 explained gaps is more useful than one that quietly drops the 60.
What you get
A contact list ready to use
One row per person with name, current title, company, LinkedIn profile, and work email, delivered in your CRM, a Google Sheet, or a CSV file.
A confidence label on every address
Each email is marked verified, catch-all, risky, unverified, or invalid, along with the source that found it, so you can choose what to send to.
A record of the people Kite couldn't find
Each gap comes with its reason, so you know whether to try a connected tool, find a different contact at that company, or reach the person another way.
Corrections to your list
People who have changed jobs are flagged, and companies missing a website have one filled in.
An outreach campaign, if you want one
Personalized emails for the people on the list, sent after you approve them, with a report on delivery and replies.
How to get started
Start by giving Kite your list and saying what it's for. You might write, "Find work emails for the people in this sheet. We're inviting them to a dinner in Austin," or, "Get me verified emails for the 150 heads of marketing in our CRM who don't have one yet."
Kite reads the list, tells you how many rows are ready to look up and what it needs to fill in, and asks any questions that change the result. For example, it may ask whether you want only verified addresses or whether catch-all addresses are fine. Then it runs the lookup and comes back with the finished list.
You don't need to connect anything to start, because the email finder is built in. Connect a CRM or Google Sheets when you want Kite to read the list from there or save the results there. Connect Hunter, Findymail, Dropcontact, Icypeas, FullEnrich, or BetterContact if your team already pays for one and wants Kite to use it. Kite asks for your approval before it sends any email, and you can give it more independence once you trust how it works.

Common questions
How do I find one person's work email address?
The quickest way is to give an email finder the person's full name and their company's website, or their LinkedIn profile. You can ask Kite the same way: "Find the work email for Priya Shah, head of growth at Northwind." Kite confirms she still holds that role, looks up the address, checks it, and tells you how confident it is. If you know the company but not the person, Kite can find who currently holds a role there first, then find their email.
Do I need my own email finder account to use Kite?
No. Kite's email finder is built in and searches several data sources without a separate subscription. Connecting your own Hunter, Findymail, Dropcontact, Icypeas, FullEnrich, or BetterContact account is optional. It's useful when your team already pays for one and wants to use those credits, or wants a second source for the people the built-in finder missed.
What does a catch-all email address mean, and should I send to it?
A catch-all address belongs to a company whose mail server accepts mail sent to any address at its domain. That means a verification check can't confirm whether the specific mailbox exists. Many catch-all addresses are real, and some will bounce. If your sending domain is new or your bounce rate is already high, send to verified addresses first. If you need to reach those people, send to catch-all addresses in smaller batches and watch the bounces. Kite keeps the label on every address so you can make that choice for each campaign.
Is it legal to send cold email to work addresses I find?
In the United States, the CAN-SPAM Act allows commercial email to people who haven't opted in, as long as the message identifies the sender honestly, includes a physical mailing address, and gives a working way to opt out that you honor. In the European Union and the United Kingdom, rules are stricter: data protection law generally requires a legitimate business reason to contact someone, and some countries require consent before emailing individuals. Check the rules for the countries you're emailing. Kite only collects professional details relevant to your business purpose, leaves personal addresses out, and removes anyone your team has recorded as opted out before a list feeds a send.
Can Kite find emails if I only have a list of companies?
Yes, but it finds the people first. Tell Kite which roles you want at each company, such as the head of marketing or the founder, and it identifies who holds those roles today, confirms each one from a public source, and then finds their work emails. If you want Kite to build the company list too, starting from your ideal customer profile, see Build qualified B2B lead lists.
