For agencies
Lead generation software for agencies, one workspace per client
FoxKnock is lead generation software for agencies that run outbound for clients: each client gets a separate workspace with its own data, mailboxes, suppression list and approvals, and by default every email waits for a person to approve it.
Running outbound for clients means sending from their domains, under their names, with your reputation attached. Research is cited, so you can show a client where each researched fact came from.
500 free credits, no card, and every email waits for your approval by default.
What gets in the way today
Every email goes out under a client's name
A wrong job title, an invented compliment or a congratulation that is two years late lands in a real inbox, from a domain your client built. The client sees the complaint, not your tool.
Client lists bleed into each other
When several clients share one account, an unsubscribe, a bounce or a do-not-contact rule at one client can miss another, and a mistake in one campaign can pause everyone's sending.
Clients ask where each line came from
"Why this account? Where did you get that detail?" Answering from memory or a spreadsheet takes time, and an answer you cannot source erodes trust faster than a slow month.
How it works for agencies
- 1
Open a workspace for each client
Create the workspace, paste the client's website (or a short description if there is no site) and, if you have them, their best customers. FoxKnock writes a playbook with the offer, value props, 3 to 5 segments and "never claim" rules. Everything in it is editable.
- 2
Start from the Today queue
Each workspace ranks up to 25 accounts by fit, signal strength and freshness. Find more with Describe, Lookalikes, Local businesses or People search, and pay only for the results you accept. With signals (a Growth plan feature and above), monitors check hiring, funding, news and tech changes hourly, daily or weekly.
- 3
Research, draft and approve
Standard research turns an account into evidence cards with source links. AI drafts cite those cards, a quality gate blocks unsupported claims, and your team approves in a keyboard-first queue (A approves, E edits). Start at review each, then move steady sequences to batch approve.
- 4
Handle replies and report
The AI inbox sorts replies into 13 classes, and hot replies and meetings can post to a Slack channel you choose. Each workspace has its own analytics page, and the REST API and signed webhooks feed whatever report you build for the client.
What you can count on
Product facts, not promises: each one is how FoxKnock works today.
- Up to 25 client workspaces on the Agency plan ($399/month), each a separate tenant with its own data, mailboxes, suppression list and approvals.
- Four approval levels, set per sequence, with review each as the default. Auto within limits unlocks only after 50 emails approved one by one, with under 10% edited and under 5% rejected, and nothing is ever approved by a timer.
- Every research fact is an evidence card with a source URL, a verbatim quote and a read date. Cards expire (90 days for news, hiring and funding, a year for the rest), and specific claims in AI drafts must cite one.
- Per-mailbox guardrails: 25 sends a day by default (50 at most), a send ramp that takes 21 days to reach the limit, and an automatic pause above 2% bounces (last 100 sends) or 0.1% complaints (last 1,000 sends, from feedback-loop reports).
- Suppression, country rules and lawful basis are checked when a contact is enrolled and again at send time, per workspace, with a kill switch that pauses one client's sending without touching the others.
- A REST API and 13 signed webhook events (including message.replied and meeting.booked) so reporting can flow into your own tools.
What to look for in outbound agency tools
Outbound for clients is different from outbound for yourself. Emails go out from a client's domain, replies belong to the client's pipeline, and sooner or later the client asks where a claim came from.
When you compare outbound agency tools and other lead gen agency software, check three things:
- Separation. Can you change or pause one client's sending without touching another's?
- Brakes. Does a person approve what goes out, and are risky moves slowed down?
- Trail. Can you show a client where each claim came from?
FoxKnock is built around those three. It is designed for researched, small-batch outbound, not for blasting thousands of contacts a week.
One workspace per client
On the Agency plan one person can own up to 25 workspaces, and the one that holds the subscription counts toward the 25. Each is a separate tenant with its own data, mailboxes, suppression list, approvals, country rules and kill switch.
- An unsubscribe at one client stays on that client's suppression list.
- Pausing one client's sending leaves the rest running.
Each workspace also gets its own playbook. FoxKnock reads the client's website and drafts the offer, segments and a set of "never claim" rules. Those rules are hard constraints for both the email writer and the claim checker.
How to manage cold email for clients
Start every client sequence on review each, the default: a person approves each email before it sends. A quality gate runs first. It blocks drafts with unsupported claims or unresolved variables and flags spam words and AI-sounding phrases, so your team's time goes on judgement calls.
You can loosen this later, one sequence at a time:
- Batch approve lets you approve in bulk the drafts that passed the gate.
- Auto within limits has to be earned per sequence, as approval-first outreach explains.
- The one send that needs no per-message approval is an opt-in auto-reply that sends your own booking link to a meeting request. It is off by default.
Under all of that, each mailbox is capped and ramped, and pauses itself on high bounces or complaints. These guardrails are meant to lower the risk to a client's domain. They cannot promise inbox placement.
For EU clients, FoxKnock includes built-in GDPR tools, but compliance stays with the sender and the rule packs are not legal advice.
Connecting client mailboxes
FoxKnock connects mailboxes only with a password over SMTP and IMAP. That means Google Workspace or any SMTP and IMAP mail server, connected with an app password. There is no Google or Microsoft sign-in.
- Google Workspace: an app password needs 2-Step Verification and may not be offered on some work accounts, so someone with access to the client's mailbox has to create it.
- Microsoft 365: limited. Microsoft says it has disabled Basic authentication for IMAP in all tenants and is retiring it for SMTP AUTH. A password is Basic authentication, so a Microsoft 365 mailbox may not connect or may not sync replies, and reply sync needs IMAP. Test a client's Microsoft 365 mailbox before you plan around it, or use a mailbox on another SMTP and IMAP provider.
What lead gen agency software costs per client
Credits and plans are per workspace
Read this before you plan a budget. Plan, credits and the monthly spend cap are set per workspace today, and credits are not pooled.
- The Agency subscription's 60,000 monthly credits go to the workspace that holds it.
- A new client workspace starts on the Free plan with its own billing page and no credits. You fund each one on its own, with a plan or with top-up packs.
- A workspace on the Agency plan has unlimited seats and mailboxes. Every other workspace has the seats and mailboxes of its own plan (a Free workspace has 1 seat and 1 mailbox).
- There is no client portal and no per-client invoicing, so you bill your clients yourself.
An example month (hypothetical)
For example, a 3-person agency runs outbound for three clients. In each client workspace it adds 80 companies, researches the 20 best fits and contacts one person at each company. The figures use default credit prices (they may change, see pricing), where 1 credit = $0.01 at list price.
| Step | Volume | Credits |
|---|---|---|
| Accept discovery results | 80 × 15 | 1,200 |
| Standard research on the best fits | 20 × 225 | 4,500 |
| Find one contact per company | 80 × 5 | 400 |
| Find and verify one email per contact | 80 × 11 | 880 |
| AI-personalized first email for researched accounts | 20 × 20 | 400 |
| Total per client | 7,380 |
That is about $74 at list price per client, or about 22,100 credits across the three workspaces, each funded separately. Three things to know about the table:
- It assumes every lookup succeeds (failed lookups are free).
- It leaves out signal monitors, regenerated drafts and the 1-credit re-check before sending, which applies when an address was last verified more than 14 days ago.
- The other 60 accounts get a template email, which costs nothing but is not claim-checked, so keep specific claims out of it.
When a client asks where a detail came from, open the research report: each one shows its sources.
Which plan fits
- One client: you do not need 25 workspaces. Growth ($149/month, 20,000 credits, 5 seats, 15 mailboxes, one workspace) covers the example month with room to spare, and unused credits roll over.
- Two or more clients: Agency ($399/month, 60,000 credits) is the plan that lets you own more than one workspace, up to 25 (Enterprise is custom). Put the subscription on the workspace that will use the most credits, and budget the others separately, as above.
What FoxKnock will not do for agencies
- No white-label reports. There is no report builder and no client branding. You get an analytics page per workspace, CSV exports of companies and contacts, the REST API and webhooks, and the work of building the report you want.
- No pooled credits, client portal or client invoicing.
- No open or click tracking. Reporting rests on replies and on meetings your team marks as booked.
- LinkedIn stays manual. FoxKnock does not scrape LinkedIn. LinkedIn steps become tasks with a drafted note your team sends by hand.
- No one-click mailbox connect, and Microsoft 365 is limited. Mailboxes connect with a password over SMTP and IMAP, not with Google or Microsoft sign-in (details are under connecting client mailboxes).
- No promises on inbox placement or reply rates.
Try it first
Try FoxKnock on your own market with the free credits: 500 one-time credits, given once per person to the first workspace you create (after you verify your email), with no card needed. Writing a playbook costs no credits, and 500 credits cover two standard research reports at default prices.
Frequently asked questions
How do I manage cold email for clients?
Give each client a workspace. Connect that client's mailboxes with an app password over SMTP and IMAP (Google Workspace or any SMTP and IMAP mail server), set the approval level on each sequence, and approve drafts in the queue. Suppression, country rules and the kill switch are per workspace, so one client's settings do not carry over to another.
How much does lead generation software for agencies cost?
FoxKnock's Agency plan is $399 a month for up to 25 client workspaces and 60,000 credits, which go to the workspace that holds the subscription. Each other client workspace is funded on its own. A single client can run on Growth at $149 a month. In the example month on this page, one client uses about $74 of credits at default prices (they may change, see pricing).
Can agencies share credits across client workspaces?
No. Plan, credits and the monthly spend cap are per workspace today. The Agency plan's 60,000 monthly credits go to the workspace that holds the subscription. A new client workspace starts on the Free plan with no credits, so you fund it with its own plan or top-up packs.
Can I connect my clients' Microsoft 365 or Outlook mailboxes?
Not reliably. FoxKnock connects mailboxes only with a password over SMTP and IMAP, and Microsoft says it has disabled Basic authentication (passwords) for IMAP and is retiring it for SMTP AUTH. A Microsoft 365 mailbox may therefore not connect, or may not sync replies. FoxKnock does not offer Microsoft sign-in. Google Workspace or any SMTP and IMAP mail server, connected with an app password, is the way to connect.
Does FoxKnock have white-label reports for clients?
No. There is no report builder or client branding. Each workspace has an analytics page with reply, positive reply and meeting rates and cost per meeting (meetings count only when your team marks them as booked). You can also export companies and contacts as CSV, or pull data through the REST API and webhooks into your own reports.
Does approving every cold email slow my team down?
A little, and on purpose. The approval queue is keyboard-first, and the quality gate has already blocked drafts with unsupported claims, so your time goes on judgement calls such as whether the offer fits the account. Steady sequences can move to batch approve, which only covers drafts that passed the gate. Auto within limits is optional and has to be earned per sequence.
Does FoxKnock help with GDPR for client campaigns?
It includes built-in GDPR tools: country rule packs, lawful-basis tracking, a privacy-notice link in first emails, suppression lists, retention, and access export and erasure. Compliance stays with the sender, and the rule packs are a starting point, not legal advice.
Where is my clients' data stored?
FoxKnock runs on a Hetzner server in Nuremberg, Germany. AI features use Claude, by Anthropic, so the text those features work on (research, drafts and replies) is sent to Anthropic. Lookups may also go to the data and search providers behind them. Tell your clients before you add their data.
