Outbound stops when you ship
A launch week, a hiring push or a fundraise and the emails stop. When they stop, the pipeline dries up a month later.
Industries · Startups
Cold email for startups that finds your first customers while you build.
You have a product and no sales team. FirstSales finds the people most likely to buy, writes each one a personal email in your voice and follows up until they reply, so outbound keeps running on the days you are shipping.

The problem
The founder is the sales team, and the founder is busy.
Most early teams know outbound works. They just cannot do it every day next to everything else.
Hiring sales is too early
A first sales hire is costly and slow to ramp, and you still need to know what message works before you hand it over.
One domain, no room for mistakes
Blast from your main domain and investor updates, invoices and login emails start landing in spam too.
How it works
From a one-line pitch to booked calls, in three steps.
You describe your product and your buyer. FirstSales does the daily work and hands you the replies.
- 01
Tell it what you sell
Paste your website and a few lines on who you help. Describe the companies and roles you want as early customers.
- 02
It finds, writes and sends
FirstSales builds the lead list, checks every address, writes each person an email in your voice and sends from warmed-up mailboxes.
- 03
You take the calls
Follow-ups go out on time and stop on a reply. Interested people get your meeting link, and you see every reply in one inbox.
Your first month
From sign-up to first replies: what a founder's first 21 days look like.
You do not need a sales team or a long setup. This is the plain path most early teams follow, with the parts FirstSales does for you in the background.
Day 1
Connect a mailbox and teach it your pitch
Add a Gmail, Outlook or SMTP mailbox on a separate domain. Paste your website and a few lines on who you help. SPF, DKIM and DMARC are checked and warm-up starts on its own.
Days 2 to 6
Pick a first segment and build the list
Describe the companies and roles you want as early customers. FirstSales builds the lead list and checks every address. Contacts marked Dirty are left out before anything sends.
Day 7
Write the first campaign and read the drafts
Set your tone, add a few instructions and let the AI draft one email per person. Read them in the approval queue. Fix what sounds wrong once and the next drafts follow.
Day 21
Warm-up done, sending ramps up
The 21-day warm-up has run its three phases. Add more mailboxes if you want more volume, since they are unlimited. Sending rotates across all of them.
After that
Read replies, keep what works
Replies land in one inbox. Interested people get your meeting link. A/B test subject lines, change the angle that is not landing and open a second segment.
What you get
A full outbound motion, for the price of one tool.
Everything an early team needs to find first customers by email, in one app, on every plan.
Leads without a research week
Describe your ideal customer in plain words and FirstSales builds the list. Or upload the names you already have.
Your voice, not a template
Set the tone and style once and add your own instructions. Emails read like a founder wrote them, because the AI writes from your words.
Follow-ups while you build
Every prospect is followed up on plan until they reply or opt out. You do not have to remember who to chase.
Your main domain stays safe
Send from separate domains. Each mailbox gets a 21-day warm-up, hourly inbox monitoring and a health grade.
Room to grow
Mailboxes, workspaces and team members are unlimited on every plan. Your first sales hire joins the same account.
Learn what message works
Opens, replies, meetings and bounces per campaign. A/B test subject lines and keep the pitch that gets answers.
Set it up in an afternoon,then get back to building.
Four parts of the app do the outbound work a founder usually squeezes in late at night.
- Connect
Connect a mailbox on a separate domain
Add Gmail, Outlook or any SMTP mailbox. Keep cold email off the domain that sends your invoices and logins, and add more mailboxes when you want more volume.
- SPF, DKIM and DMARC checked. With the exact record to add if one is missing.
- Warm-up starts. 21 days in three phases, in the background.
- Sending rotates. Volume is shared across all your mailboxes.
- Voice
Make it sound like the founder
Pick a tone and a writing style, then add instructions the way you would brief a new hire: what to say, what never to say, how to sign off. The AI writes inside those lines.
- Tone and style. Short and direct, or detailed and warm.
- Custom instructions. Your rules, applied to every draft.
- Knowledge base. Your website and docs, so facts stay true.
- Write
One personal email per person
Each email starts from the prospect's company and role. Follow-ups can reference the last email and try a new angle, so a short sequence still feels like one conversation.
- Follow-ups that build. Each one can reference the last and change the angle.
- Approval queue. Approve, edit or reject drafts before they send.
- Manual mode. Prefer your own words? Send your templates, no AI.
- Reply
Every reply in one inbox
Replies from every mailbox land in one place, sorted by what needs you. Interested people are offered your meeting link, so a reply becomes a call without back-and-forth.
- One inbox for every mailbox. No logging in to five accounts.
- Stops on reply or opt-out. The sequence ends as soon as someone answers.
- Meetings offered for you. Interested replies get your booking link.
Your first buyers
Early customers come from a few kinds of people. Write to each one differently.
A startup rarely sells to one job title. These are the people founders most often reach first, what they want to hear and the angle that tends to start a conversation.
- 01
A founder at a company like yours
- What they care about
- Speed, cost and anything that saves the small team a week. They are open to new tools and decide alone.
- The angle that gets a reply
- Write founder to founder. One problem you both know, one line on how you fixed it, one easy question.
- 02
The person who feels the problem daily
- What they care about
- Their own workload. They will try something new if it removes a task they hate.
- The angle that gets a reply
- Name the task in their words and offer to show the shortcut. They often bring in the buyer for you.
- 03
A team lead at a mid-size company
- What they care about
- Hitting this quarter's goals without adding headcount or a long rollout.
- The angle that gets a reply
- Offer a small, low-risk start. A pilot with one team is easier to say yes to than a company-wide change.
- 04
A budget owner at a larger company
- What they care about
- Risk. A young vendor has to feel safe, clear and easy to stop.
- The angle that gets a reply
- Be plain about who you are and how small the first step is. Do not pretend to be bigger than you are.
- 05
A design partner
- What they care about
- Shaping a product to fit their need, and early access in return for feedback.
- The angle that gets a reply
- Ask for their opinion, not a purchase. Many first customers start as people who wanted to help build it.
- 06
A connector or advisor
- What they care about
- Helping good founders and looking smart to their network.
- The angle that gets a reply
- Ask for one specific intro to one kind of person. A narrow ask is easy to act on.
Plain guide
How to do cold email as an early-stage startup.
What works for founders selling their own product, in plain words.
- 01
Use outbound to learn, not just to sell
Your first campaigns tell you who cares and which words land. Treat every reply, even a no, as research. Change one thing at a time: the segment, the problem you lead with or the ask. FirstSales shows replies per campaign and lets you A/B test subject lines, so you can see what moved.
- 02
Pick a segment you can name in one line
"Heads of support at online stores with a small team" is a segment. "SMBs" is not. A narrow segment makes every email specific and every reply useful. Describe it in those plain words and FirstSales builds the list from that description.
- 03
Write like a founder, because you are one
Buyers answer people, not companies. A short note that says who you are, why you built this and one question is more honest than a polished pitch. Set your tone and instructions once and the AI keeps that voice in every draft.
- 04
Ask for a reply, not a demo
A first email that asks for 30 minutes asks too much of a stranger. Ask if the problem is real for them. A yes opens the door, and your meeting link does the rest.
- 05
Keep your main domain out of it
Buy a second domain for cold email and warm up each mailbox for 21 days. Keep volume per mailbox low and add mailboxes rather than pushing one harder. FirstSales gives you unlimited mailboxes and rotates sending across them.
- 06
Follow up, then stop
Most replies come after the first email. Plan a few follow-ups, each with something new, and stop the moment someone answers or asks you to. FirstSales ends the sequence on any reply or opt-out.
Real objections
What buyers say to a young company, and what to write back.
Early-stage founders hear the same doubts again and again. Each one has a calm, honest reply. The AI writer can draft these replies for you to approve.
What they say
What you write back
“You're too early for us.”
Agree on what is true and offer a small, safe first step. Ask what would need to be true for them to try it.
“Who else uses this?”
Be honest about where you are. Share what early users have said only if it is real, and offer a short trial.
“We could build this ourselves.”
They might. Ask what it would cost their team in time and what they would stop building to do it.
“Not now, maybe next year.”
Ask what changes next year and offer to check in then. Add them to a later follow-up, not a weekly chase.
“What happens if you shut down?”
A fair worry. Explain how they can export their data and stop at any time. Clear exits make starting easier.
“Send me a deck.”
Send one short page and a single question about their situation, so the next reply is a real conversation.

Good practice
Cold email as a small team: protect the one name you have.
A startup has one brand and often one domain. These are general truths that keep it safe while you reach new people.
- Keep your main domain cleanYour main domain sends invoices, logins and investor updates. Send cold email from a separate domain so a mistake there does not reach those.
- Say who you areReal name, real company, real reply address. A small company earns trust by being plain about itself.
- Do not fake tractionNo invented customers, logos or results. The knowledge base keeps the AI to the facts you give it.
- Make saying no easyOffer a simple way to opt out and honour it. FirstSales stops follow-ups when someone replies or opts out.
- Write to people about their workReach people in their work role about a work problem. Privacy rules in many places rely on that link.
- Start slowLow volume per mailbox, a warmed-up domain and a checked list matter more than a clever subject line.
This is general information, not legal advice. FirstSales gives you the tools to send with care; you decide who to contact and are responsible for following the rules where you and your prospects are.
