Cold email lead generation
Cold email still works — when the list is targeted, the addresses are verified, the domain is warm and the message is relevant. Here's how cold email lead generation actually works end to end, and the mistakes that send it to spam.
- Verified emails = fewer bounces
- Checked against the live mail server
- 5 free contacts, no card
- GDPR & DPDP compliant
In this guide
Most "cold email doesn't work" stories are really "my list was bad and my domain was cold" stories. Get the plumbing right and cold email is one of the most cost-effective lead channels in B2B.
The five steps
-
Build a targeted list
Start from your ideal customer profile and find the specific people who fit — right role, right company — usually on LinkedIn. A small, precise list beats a big, vague one every time.
-
Get verified emails
This is where campaigns are won or lost. Every unverified address is a bounce waiting to happen, and bounces destroy deliverability. Use a finder that verifies against the live mail server.
-
Warm up the domain
A brand-new sending domain with no reputation goes straight to spam. Warm it up gradually, and set up SPF, DKIM and DMARC before you send a single campaign.
-
Personalise and send
Relevance beats volume. A short, specific message to 50 well-chosen people outperforms a generic blast to 5,000.
-
Follow up
Most replies come from follow-ups, not the first email. Two or three polite, spaced touches — then stop.
Step two, solved
GetLeadz returns the verified work email from a LinkedIn profile, checked against the live mail server — so your list bounces less and lands more. Five free to start, nothing charged on a miss.
Lower bounce rate, better deliverabilityDeliverability: the hidden killer
You can write the best cold email in the world and never know, because it landed in spam. Deliverability is decided before anyone reads a word:
- Verify every address. A bounce rate above a few percent gets you throttled by Gmail and Outlook.
- Authenticate the domain. SPF, DKIM and DMARC are non-negotiable.
- Warm up gradually. Ramp volume over weeks, not days.
- Keep volume human. Blasting thousands from one inbox is a spam signal in itself.
Writing cold email that gets replies
- Short. Five sentences or fewer. They'll read it on a phone between meetings.
- Relevant. Reference something specific about them or their company, not a template variable.
- One ask. A single, easy next step — a question or a low-friction call.
- Human. Write like a person, not a marketing sequence.
Staying compliant
B2B cold email is permitted in most markets under conditions: be transparent about who you are, keep it relevant to the person's role, offer a genuine opt-out, and stop when asked. The EU (GDPR legitimate interest) and the US (CAN-SPAM) differ in detail but agree on those principles. See ethical ways to find contact information. This is general information, not legal advice.
FAQ
What is cold email lead generation?
Cold email lead generation is the practice of generating B2B leads by emailing prospects who have had no prior contact with you. Done well it means a tightly targeted list, verified work emails, careful deliverability, relevant personalised copy, and compliance with rules like GDPR and CAN-SPAM.
Is cold email legal?
B2B cold email is permitted in most markets under conditions: in the EU legitimate interest usually applies if you're transparent, relevant and offer an easy opt-out; the US CAN-SPAM Act requires accurate headers, a physical address and a working unsubscribe. Contacting a work address about a work role is treated more leniently than a personal one. This is general information, not legal advice.
Why do my cold emails land in spam?
Usually deliverability, not content. Sending to unverified addresses causes bounces that wreck your sender reputation; a cold domain with no warm-up, missing SPF/DKIM/DMARC, and high volume all push you to spam. Verify every address, warm up the domain, and keep volume sane.
How do I find emails for cold outreach?
Build your target list on LinkedIn or from your ICP, then get each person's verified work email with a contact finder. GetLeadz returns the verified email — checked against the live mail server — from a LinkedIn profile, so your list bounces less and lands more.
