Tips without a sequence
A thread on subject lines, a post on warmup, a video on follow-ups. Each one makes sense alone. Together they do not tell you what to do first.

Every lesson maps to a step you can run
The problem
Cold email advice is everywhere, but it rarely comes in order.
You can find a tip for every step online. What is hard to find is the order they go in, and which ones matter for the problem you have today.
The setup gets skipped
Most guides jump straight to the copy. But a great email from a cold domain with no authentication never reaches the inbox, so the copy never gets a chance.
Knowing is not running
Even when you know every step, doing all of them every day for every lead is a full-time job. Most people learn the loop, then run out of hours to keep it going.
How it works
Read it, use it, then hand it off if you like.
The masterclass teaches the loop by hand, so you understand every part. What you do with it next is up to you.
- 01
Read the chapters you need
Go front to back, or pick a reading path for your situation. Each chapter is short enough for a coffee break and ends with what to do next.
- 02
Use one lesson at a time
Fix your setup this week, your list the next, your follow-ups after that. Small changes in the right order beat a full rebuild that never ships.
- 03
Let FirstSales run the loop
When you would rather spend your time on the calls, FirstSales finds leads, researches them, writes each email, sends from warmed inboxes and follows up for you.
The course
Fifteen chapters, in the order you need them.
Each chapter has its own page, so you can read straight through or jump to the problem in front of you. The early chapters set up your sending. The later ones help you measure, stay compliant and grow.

01
Foundations
Why cold email still works, the mindset that earns a reply, the domains and mailboxes you send from, warming them up, and building a list worth writing to.
02
Writing and follow-up
How a cold email is put together, how to make it about one person without spending all day on research, and how to follow up without nagging.
03
Delivery, channels and measurement
Keeping your mail out of spam over time, adding other channels where they help, using AI well, and reading the numbers that matter.
04
Compliance and scale
The rules you have to follow, how to grow volume without hurting your sender reputation, and a few tactics most senders never try.
Where to start
Short on time? Read the chapters for your problem.
You do not have to read all fifteen in one go. Pick the situation closest to yours and start there. Every chapter links to the next one when you are ready.
You have never sent cold email
Start with the why and the mindset, then set up your domains and mailboxes properly before you write a word. Most early mistakes happen here, not in the copy.

You send, but few people reply
Low replies are usually a list problem or a message problem. Check who you are writing to, then rebuild the email, the personal touch and the follow-ups.

What you get
A complete course, written in plain English.
No fluff, no upsell in every paragraph. Just the parts of cold email that decide whether you get replies, explained so you can act on them.
The full loop, start to finish
Mindset, setup, warmup, lists, writing, personalisation, follow-ups, deliverability, other channels, AI, measurement, compliance and scale. One course, one order.
Setup before copy
Three chapters cover domains, mailboxes, authentication and warmup before you write a word. That is where most cold email quietly fails.
Written for people who send
Founders, SDRs, agencies and consultants. Each chapter is about what you do on a Tuesday morning, not theory you will never use.
Free and open
Every chapter is a public page. There is no signup, no email gate and no paywall halfway through. Share it with your whole team.
Short chapters
Most chapters are a single sitting. Read one before a campaign goes out, or keep the whole course open as a reference while you work.
Ties into real tools
Where a lesson matches a FirstSales feature, like warmup, verification or follow-up sequences, you can see how it runs in practice.
How the masterclass fitsinto the work you already do
A course is only useful if it changes what you send. Here is how to read it, check your work against it and hand the routine parts to software.
- Read
A chapter for each part of the loop
Every chapter opens on its own page with the full table of contents beside it, so you always know where you are and what comes next. Read straight through, or open the chapter that matches today's problem and come back for the rest later.
- Table of contents. All fifteen chapters, one click away.
- Previous and next. Each chapter leads to the next.
- Read time shown. Know how long before you start.
- Check
Turn each chapter into a pre-send check
The chapters end with clear actions. Collect them into a short list and run it before every campaign: is the domain authenticated, are the mailboxes warm, is the list verified, does the email read like a note from one person, are the follow-ups spaced and does the sequence stop on a reply.
- One line per lesson. Short enough to run every time.
- Setup first. Delivery checks before copy checks.
- Catch it before you send. Not after a week of silence.
- See the loop
See how the parts connect
Cold email is a loop, not a list. Your setup decides whether you reach the inbox. Your list decides who reads it. Your writing decides whether they reply. Your follow-ups catch the ones who were busy. Your numbers tell you which part to fix next, and the loop starts again.
- Setup and warmup. Reach the inbox at all.
- List, write, follow up. Reach the right person, well.
- Measure. Know which part to fix next.
- Hand off
Hand the routine parts to FirstSales
Once you know how the loop works, you can decide which parts to run yourself. FirstSales warms your inboxes, verifies every address, researches each lead, writes each email for one person, sends the follow-ups and stops when someone replies. You keep the parts that need you: the offer, the rules and the calls.
- Warmup and verification. Running before the first send.
- Writing and follow-ups. One email per person, spaced out.
- You stay in charge. Your offer, your rules, your calls.
The short version
Six lessons that run through every chapter
If you only remember a few things from the masterclass, make it these. They hold whatever you sell and whoever you sell to.
- 01
Delivery comes before copy
If your email never reaches the inbox, nothing else matters. Send from a separate domain, set up SPF, DKIM and DMARC, warm new mailboxes slowly and keep daily volume modest per mailbox. Only then is it worth working on the words.
- 02
Your list matters more than your message
A perfect email to the wrong person goes nowhere. A plain email to the right person at the right moment often gets a reply. Spend real time on who you write to, and verify every address so bounces do not hurt your reputation.
- 03
Write to one person
A cold email should read like a note from one person to another. Keep it short, plain text, no images and no wall of links. Open with something about them, say why you are writing in one line and ask one easy question.
- 04
Most replies come later
People are busy, and the first email often lands at the wrong moment. Follow up a few times, space the emails out, add something new each time, and stop the moment they reply or ask you to stop.
- 05
Measure the few numbers that matter
Track bounces, replies and meetings by campaign. Open rates are a weak signal now that many mail apps load images on their own. If replies drop, look at the list and the message. If bounces rise, look at the list and the setup.
- 06
Grow slowly and stay within the rules
Add mailboxes and domains instead of pushing more through one. Honour every opt-out quickly, say who you are and why you are writing, and learn the rules for the countries you send to. Reputation takes months to build and days to lose.
Before your next campaign,
run through this list
One line for each part of the loop. If you cannot tick a line, the chapter for it is linked above.
- Sending domain is separate from your main domain
- SPF, DKIM and DMARC are set up and passing
- New mailboxes have been warmed up before cold sends
- Daily volume per mailbox is modest
- Every address on the list has been verified
- Each lead fits who you actually sell to
- The email is short, plain text and about them
- There is one clear, easy question at the end
- Follow-ups are spaced out and add something new
- The sequence stops as soon as someone replies
- Every email has a simple way to opt out
- You know which number you will judge it by
“One of the biggest pains in cold email is making sure that you have your DNS setup correctly. Firstsales has created a system to make sure you have done this correctly.”

01What is the FirstSales cold email masterclass?
It is a free course in fifteen chapters that covers the whole cold email loop: why it still works, the mindset, setting up domains and mailboxes, warmup, list building, writing, personalisation, follow-ups, deliverability, other channels, AI, measurement, compliance, scaling and a few advanced tactics.
02Is it really free?
Yes. Every chapter is a public page. There is no signup, no email gate and no paywall. You can read all of it without creating an account.
03How long does it take to read?
Each chapter shows its read time, and most take one short sitting. Together they add up to about two hours. You can read it all at once or one chapter at a time.
04Who is it for?
Anyone who sends or plans to send cold email: founders doing their own outreach, SDRs, agencies and consultants. The early chapters suit beginners. The later ones help teams who already send and want to grow.
05Do I have to read the chapters in order?
No. The order follows the loop, so reading front to back works well. If you have a specific problem, like low replies or emails landing in spam, use one of the reading paths above and jump straight in.
06Do I need FirstSales to use what I learn?
No. Everything in the masterclass works with any setup. FirstSales is there for when you would rather not run every step by hand: it can warm your inboxes, verify addresses, research leads, write each email and send the follow-ups for you.
07Is cold email legal?
In many countries cold email to businesses is allowed when you follow the rules, but the rules differ by country. The compliance chapter covers the basics. It is general information, not legal advice, so check the rules where you send.
08Can I share the masterclass with my team?
Yes. Share the link with anyone. Each chapter also has its own address, so you can send a colleague straight to the part they need.
Outreach that keeps going after you log off.Leads, emails, follow-ups and replies, handled.
Connect unlimited mailboxes and let AI agents find leads, write each email and follow up. Or send your own templates in manual mode. From $29/mo.
