Templates sound like templates
Swap in a first name and a company, and it is still the same email everyone else got. Buyers can tell, and they do not answer.

The problem
Cold email is easy to send. It is hard to write well, at volume.
A good cold email is short, about the reader and easy to answer. Writing hundreds of those by hand does not fit in anyone's week.
Generic AI does not know your product
A chat window can write a nice paragraph, but it does not know what you sell, who it is for or what you are allowed to claim. You end up rewriting every draft.
Writing by hand does not scale
Researching each prospect and writing a real email takes minutes per person. Multiply by a list, and outreach stops the moment you get busy.
How it works
From your product facts to a sent email in three steps.
No prompts to engineer and no blank page. You set it up once per campaign.
- 01
Give it the facts
Connect a knowledge base for context and brand voice, and pick the offering the campaign is about.
- 02
It writes for each contact
The Email Drafter writes a new email for each contact, using their data and the campaign goal.
- 03
You approve, it sends
Approve, edit or reject drafts in the queue, or let them send on their own. Replies stop the sequence.
Inside one draft
What a first email looks like, part by part.
The writer aims for a short first email that is easy to answer. Here is an example draft, broken into its parts, with a note on why each part is there.
Example draft
01 Subject
Quick question about Northwind's front desk
Short and specific to their company. You can A/B test subject lines to see which one gets more opens and replies.
02 Opener
Hi Maya, I saw Northwind just opened a second clinic in Leeds.
One line about them, taken from the contact's data. It shows this email was written for one person.
03 Reason
Clinics that grow to two sites often find the front desk spends hours each week moving bookings between calendars.
Why it matters to them, in their words. This comes from your knowledge base, not from a guess.
04 Offer
We built a booking tool that keeps both sites on one calendar.
One sentence on what you sell, taken from the offering you picked. No feature list.
05 Question
Is that a problem at Northwind, or is it already handled?
One easy question. A yes or a no both start a conversation.
06 Sign-off
Thanks, Sam
Plain and short. No booking link in the first email: interested replies get it in a follow-up.
What you get
Real emails, written for one reader, sent to many.
The writer is part of every campaign, on every plan.
One new email per prospect
Each contact gets an email written for them, from their data and your facts. Not a template with a name swapped in.
Grounded in what you sell
The writer reads your knowledge base and the offering you picked, so it talks about your real product, in your words.
Your tone, learned from replies
Your writing profile learns how you sound from real emails that got replies, so drafts start closer to your voice.
Short and easy to answer
Get-reply campaigns keep the first email short and end with one easy question. The booking link waits for a follow-up.
Nothing sends without your say
Turn on approval and every draft waits in a queue. Approve it, edit it or reject it, and the writer learns from your edits.
Your own words when you want them
Switch to Manual mode and write the email yourself with merge fields. Same tracking, same schedule, same stop on reply.
Four settings that shapeevery email it writes
All of them live in the Email Drafter node, inside the campaign.
- Knowledge base
Give the writer your facts and voice
Turn on Knowledge Base in the Email Drafter and pick which of your workspace knowledge bases to use. The writer reads them for context and brand voice, so drafts describe your product the way you do.
- Your own sources. Pick the knowledge bases that fit this campaign.
- Context and voice. Product facts and the way you talk about them.
- Add more anytime. Add a knowledge base without leaving the campaign.
- Offerings
Tell it what you are selling
Turn on Offerings and pick the product or service this campaign is about. The writer uses it as the context for personalized outreach, so every email stays on one clear offer.
- One offer per campaign. Emails stay focused on what you picked.
- Products or services. Each offering is tagged by type.
- Reuse across campaigns. Set an offering up once and pick it again later.
- Email templates
Write it yourself when you need to
In Manual mode, open Email Templates and write the subject and body yourself. Use merge fields like {{first_name}} and {{company_name}}, format the body with the toolbar or the / menu, and add A/B variants to test subject lines.
- Merge fields. Names and companies filled in per contact.
- A/B variants. Test subject lines and keep the one that works.
- A full editor. Bold, lists, links and a / command menu.
- Tracking
See what happens after it sends
Tracking is built into every campaign email: delivered, opened, clicked, bounced and more are recorded on their own. Add your own tracking domain and FirstSales checks that it is set up right.
- Built in. No extra setup to start tracking.
- Your tracking domain. Links and opens tracked on a domain you own.
- Verified setup. See at a glance when the domain is ready.
Two ways to write
Let the AI write, or write it yourself.
Every campaign can run in AI mode or in Manual mode. Both send from your mailboxes, both stop on reply, and you can switch per campaign.
AI mode
Email Drafter, AI Mode on
The writer drafts a new email for each contact from your knowledge base, your offering, the campaign goal and the contact's data. No two contacts get the same email.
- A new email per contact, not a mail merge
- Follow-ups with a fresh angle each time
- Tone learned from your emails that got replies
- Optional approval before anything sends
Manual mode
Campaign builder, Email Template
You write the subject and body yourself, with merge fields like {{first_name}} and {{company_name}}. FirstSales fills them in for each contact and sends on your schedule.
- Your exact words, every time
- Merge fields for names and companies
- A/B variants to test subject lines
- Same tracking, scheduling and stop on reply
Plain guide
How to get good cold emails from an AI writer.
The writer is only as good as what you give it. These are the habits that make the biggest difference, in plain words.
- 01
Feed it real facts, not slogans
Put the details a buyer cares about into your knowledge base: what the product does, who it is for, what changes after they use it, and what it costs. Taglines give the writer nothing to work with. Plain facts give it something true to say.
- 02
Pick one offer per campaign
An email that pitches three things gets no answer about any of them. Choose one offering for the campaign and let every email in the sequence stay on it. If you sell to two kinds of buyers, run two campaigns.
- 03
Keep the first email short
The first email has one job: start a conversation. One line about them, one reason it matters, one easy question. Get-reply campaigns are built around that shape. Save the details and the booking link for later.
- 04
Write rules for what it must never say
Tell the writer in plain words what is off limits: no prices in the first email, no claims about integrations you do not have, no fake urgency. AI Instructions keep every draft inside those lines without you rewriting each one.
- 05
Read the first batch yourself
For a new campaign, turn on approval and read the first drafts. Approve the good ones, edit the close ones and reject the rest with a reason. The writer learns from those edits, and the next batch starts closer to what you want.
- 06
Let replies teach it your tone
Your writing profile learns from real emails that got replies. The more conversations you have, the more the drafts sound like you on a good day, not like a generic assistant.
- 07
Give it enough about each contact
A personal opener needs something personal to work from. A name and an email address are not enough. Add the company, the role and anything you know that matters, such as a new office or a recent hire. The more real context each contact has, the less the writer has to fall back on general lines, and the more each email reads like it was written by someone who looked them up.
- 08
Test one thing at a time
Change the subject line or the opening question, not both. A/B variants show which version gets more replies. Keep the winner and test the next thing.
Before you let it write
Ten checks for every new campaign
Run through these once before the writer drafts for real contacts. It takes a few minutes.
- Your knowledge base has plain facts about the product
- One offering is picked for this campaign
- The campaign goal says what a good reply looks like
- AI Instructions list what the writer must never say
- The first email is set to stay short
- Approval is on for the first batch of drafts
- Contacts have the data the opener needs
- Mailboxes are connected and warm-up has started
- A tracking domain is added and verified
- Test Workflow ran without errors
