What Cold Leads does
Clients from your website
A form, a button on your site or your mailbox — every contact lands in our CRM automatically.
AI writes and replies
Templates, campaigns and chat replies drafted for you — you approve.
Sending from your mailbox
Gmail, Microsoft 365, SMTP or your domain — with limits, dry-run and unsubscribe built in.
Works with your AI agents
ChatGPT, Claude, Copilot Studio, n8n or Make can call Cold Leads as a tool through the API (Business plan): verify lists, find addresses, push leads.
Deliverability check built in
SPF, DKIM and DMARC of your sending domain checked in one click, with the exact record to add — before your first campaign goes out.
Five things you never have to do again
No more writing campaign copy
Describe the goal in one line — AI drafts the template in your language and tone, you only approve.
No more watching your inbox
Client replies are picked up from your mailbox automatically and land in each contact’s chat — with an AI reply draft.
No more babysitting campaigns
Campaigns start on schedule, feed themselves with new contacts from your site and spread sending over time on their own.
No more doing outreach alone
Delegate sending to any teammate: their own role, daily limit and AI access — you keep control of billing and settings.
No more filling in contacts by hand
AI pulls the details together and suggests the full name from the e-mail address or social profiles — one click to accept.
Start in three steps
Sign up with your e-mail or Google
Import contacts — CSV, any text via AI, or a social link
Launch your first campaign with a safe dry-run
Inside the product
Pick your starting point
Your site brings leads. Cold Leads makes sure they become conversations.
Agencies lose projects in the gap between an enquiry and the follow-up. Cold Leads captures every website enquiry, keeps a focused list of businesses worth pitching, sends personal campaigns from your own mailbox and puts every reply and next step in one queue.
Learn moreE-mail verification API
Bounces get your domain blacklisted. Check every address before it enters a campaign — from your CRM, sign-up form or a script — with one HTTP call.
Learn moreTurn every website enquiry into a client record
Contact forms deliver e-mails that get lost. Cold Leads receives the same form and creates a contact with everything you need to follow up — and can send the first e-mail for you.
Learn moreCold e-mail from your own mailbox, replies in one place
Mail sent from your real Gmail or Outlook address is trusted by inboxes and by the people reading it. Cold Leads sends through your mailbox, paces it like a human and pulls the replies back into the CRM.
Learn moreThe CRM a small business actually uses
No pipelines to configure, no consultants. Put your contacts in, write a template, pick who gets it, launch — and see who answers. Everything else (limits, unsubscribes, bounces, history) is handled for you.
Learn moreReady to work through the API and AI agents
Everything that matters for lead generation in Cold Leads is reachable over HTTP: verify addresses, find e-mails by name and domain, push leads from any form or system, move contacts along the funnel. Hand an agent the OpenAPI spec (verification, e-mail finder, contact search, credits) plus the two hooks below, and it can work with the CRM as a tool without a human copying data between windows.

What the numbers mean
- Contacts — records stored in your CRM: a prospect or a customer with the whole history.
- Campaign recipients — how many contacts one campaign can reach; a contact may receive several e-mails over time.
- Verification credits — one credit checks one address or runs one e-mail-finder lookup; the allowance renews monthly, extra packs can be bought.
- Agents — team members who sign in and work in the workspace, each with a role.
- Unlimited AI — normal interactive use in the app; automated bulk generation is rate-limited to keep it fair for everyone.
Launch setup assistance: every registered customer can request a free setup call via support — we connect your website capture, build the first list and launch the first campaign together.

Clean, verified B2B lists — from our infrastructure, never your domain
Domain burn is brutal. Cold Leads can check addresses before you send — on import, on demand or for a campaign's audience: syntax, disposable domains, role accounts and MX records, and every result says whether the mailbox itself was checked. Accept-all, disposable and inconclusive addresses go to a separate Risky bucket; addresses verified as invalid are never sent to.
Verification engine
Multi-level checks with a 30-day cache; invalid addresses are skipped automatically in every campaign, so your sender reputation stays intact.
Headless API and white-label
Verify one address, bulk lists or find an e-mail by name and domain from inside your CRM or sales tool — rebrand it as your own feature.
Flat, predictable pricing
Business: 10 000 credits a month for $99, extra credits $5 per 1 000, five parallel jobs per account. No per-seat surprises.

Frequently asked questions
What happens when the free trial ends?
Your chosen plan starts automatically on the day the 5-day trial ends and the card on file is charged; we e-mail you before that. Cancel in Settings before the end date and nothing is charged.
Is a card required for the trial, and can I cancel any time?
Yes, a card is required to start the trial — it keeps the service free of abuse. You can cancel or change your plan at any time in Settings; access stays until the end of the paid period.
What is one contact, and what is a campaign recipient?
A contact is one record in your CRM. A campaign recipient is one contact reached by one campaign — Solo keeps 200 contacts and each of its 5 campaigns can reach 50 of them, so a contact may receive several e-mails over time.
What uses a verification credit?
One credit checks one e-mail address (syntax, disposable domains, role accounts and MX records; the result says whether the mailbox itself was checked) — from the app or the API; checking the same address again also costs a credit. Verified does not mean consented: you remain responsible for having a lawful basis to contact each person.
How many mailboxes and users can I have?
One sending mailbox per workspace on every plan (Gmail, Microsoft 365 or SMTP). Solo has 1 agent, Team up to 4, Business up to 10.
Do unused contacts or credits roll over, and what if I exceed a limit?
Contacts are a storage limit, not a monthly quota. Verification credits renew monthly and do not roll over; extra packs of 1 000 can be bought at any time. When a limit is reached the app tells you and offers an upgrade — nothing is deleted.
Can I import my own list, and does Cold Leads warm up my inbox?
Yes: import CSV, paste any text for AI extraction, or capture leads from your website. Cold Leads sends from your own mailbox with a daily limit you control; it does not run inbox warm-up, so start with small volumes and grow gradually.
Is onboarding help included?
Yes. Every registered customer can request free launch-setup assistance via support — one call where we connect your website capture, build the first list and launch your first campaign together. Business plans also get 24/7 premium support.
