SaaS cold email that reaches the right buyer and books the demo.

FirstSales finds the people who buy software like yours, writes a personal email for each of their roles and follows up until they reply. Every mailbox is warmed up and checked, so your launch email does not die in spam.

The problem

Great software, empty demo calendar.

Most SaaS teams do not lack a good product. They lack a steady way to put it in front of the people who would pay for it.

Inbound alone is slow

Content and ads take months to build up, and they bring in whoever shows up, not the accounts you want. Outbound lets you pick who hears from you.

Generic sequences get ignored

Software buyers get many cold emails a week. The ones that read like a template to a list are deleted in seconds or marked as spam.

Reps spend the day on admin

Finding leads, checking addresses and writing follow-ups eats the hours that should go to calls. The pipeline moves only when someone has time.

How it works

From ideal customer to booked demo, in three steps.

You describe who you sell to. FirstSales does the daily work and hands you the replies.

  1. 01

    Describe your buyer

    Company size, industry, the roles you sell to and the problem you solve. Or upload the account list you already have.

  2. 02

    It finds, writes and sends

    FirstSales builds the lead list, checks every address, writes a personal email for each person and sends from your warmed mailboxes.

  3. 03

    You take the calls

    Follow-ups go out on time. Interested replies get your meeting link, and every reply lands in one inbox.

Who you are writing to

Six people can say yes to a SaaS deal. Each one reads for something different.

A SaaS sale rarely has one buyer. FirstSales writes from each prospect's company and role, so the head of sales and the engineer who will run the tool do not get the same email.

  • 01

    Founder or CEO

    What they care about
    Growth, burn and whether a new tool will pull the team away from the roadmap. They read email between meetings and decide fast.
    The angle that earns a reply
    One sentence on the business result and one easy question. No feature list. Ask if the problem is on their plate this quarter.
  • 02

    Head of sales or VP of sales

    What they care about
    Pipeline, quota and how much time reps spend on work that is not selling.
    The angle that earns a reply
    Name the hours your product gives back to reps, and offer a short call, not a demo.
  • 03

    RevOps or sales operations

    What they care about
    Clean data, the tools already in the stack and anything that breaks a working process.
    The angle that earns a reply
    Lead with how your product fits the tools they run today and what it replaces.
  • 04

    Head of marketing or growth

    What they care about
    Leads, conversion and proving that spend turns into revenue.
    The angle that earns a reply
    Tie your product to one number they report every month, and say how you would measure it.
  • 05

    Engineering or product lead

    What they care about
    Build or buy, integration effort and the cost of keeping something running.
    The angle that earns a reply
    Be specific: the API, the docs and what a first week of setup looks like. Skip the hype.
  • 06

    IT, security or procurement

    What they care about
    Access, data handling and the paperwork every new vendor brings.
    The angle that earns a reply
    Do not cold pitch them first. Answer their questions fast once a champion brings them in.
What you get

Outbound for software teams, without hiring a room of SDRs.

Everything you need to run cold email for a SaaS product, in one app and on every plan.

  • Leads that match your ideal customer

    Describe the companies and roles you sell to. FirstSales builds the list for you, or works from your own CRM export.

  • One email per person, not per list

    Each email is written from the prospect's company and role. The VP of sales and the engineer get different reasons to reply.

  • Follow-ups that never slip

    Every prospect is followed up on schedule until they reply or opt out. Nobody is chased after they answer.

  • Your domain stays safe

    21-day warm-up, contact checks before every send and a health grade for each inbox. Sending rotates if one has trouble.

  • An AI that knows your product

    Add your website, docs and pricing to the knowledge base. Every email uses your real facts and only says what is true.

  • See what turns into demos

    Opens, replies, meetings and bounces per campaign. A/B test subject lines and keep what gets answers.

Set it up once,then let it run every day.

Four parts of the app do the work a SaaS outbound team usually does by hand.

  1. Connect

    Connect as many mailboxes as you need

    Add Gmail, Outlook or any SMTP inbox. Unlimited mailboxes on every plan means you can spread volume across several domains and keep each one at a gentle pace.

    • SPF, DKIM and DMARC checked. With the exact record to add if one is missing.
    • Warm-up starts at once. 21 days in three phases, in the background.
    • Sending rotates. Volume is spread across all your mailboxes.
  2. Teach

    Teach it your product once

    Software is easy to describe badly. Give FirstSales your website, docs and the notes your best rep would use. It reads them before it writes a single email.

    • Knowledge base. Your site and documents, used as background for every email.
    • Offerings. The exact plan or product you want to sell, named clearly.
    • Writing profile. Real emails that got replies, so it learns your tone.
  3. Write

    A personal email for every buyer

    Pick a tone and a writing style, add custom instructions and set how follow-ups build on each other. Read the drafts first, or let them send on their own.

    • Follow-ups that build. Each one can reference the last and rotate the value point.
    • Approval queue. Approve, edit or reject drafts before they send.
    • Manual mode. Prefer your own sequence? Send your templates, no AI.
  4. Reply

    Every reply, in one inbox

    Replies from every mailbox land in one place, sorted by what needs you. Interested prospects get your meeting times; drafts wait for approval if you want them to.

    • One inbox for all mailboxes. No logging in to ten accounts.
    • Stops on reply or opt-out. Sequences end the moment someone answers.
    • Meetings offered for you. Interested replies get your booking link.
Timing

The best SaaS cold email has a reason to arrive today.

A good reason to write beats a clever line. These moments make a SaaS buyer more open to a new tool. Add them to your list or your custom instructions, and the AI writer uses them in the first line.

  • They are hiring for the job your product helps with

    A company hiring several sales reps or a first RevOps lead is about to feel the pain your product solves. The job post is public and easy to mention.

    Sample first line

    Saw you are hiring three account executives. Most teams find the first month of ramp is the hard part.

  • A new leader just started

    New heads of sales and marketing review the stack in their first months. They want quick wins and are open to change.

    Sample first line

    Congrats on the new role. When you look at the outbound stack, is speed to first meeting on the list?

  • They raised money or announced growth

    New funding usually comes with growth targets and new hires. Mention the plan, not the amount.

    Sample first line

    Reading about your expansion into Europe. Who is building the pipeline there in the first quarter?

  • They launched a product or a new market

    A launch means a new audience to reach and a team under time pressure. Offer help with the part they will struggle with.

    Sample first line

    Your new self-serve plan looks great. Are you also reaching larger teams who need a sales touch?

Plain guide

How to run cold email for a SaaS product.

What works for software teams, in plain words. No growth hacks.

  1. 01

    Pick a narrow first segment

    Start with one kind of company and one role, where your product clearly saves time or money. A narrow list lets every email speak to one real problem. Widen it once you know which words get replies. FirstSales builds the list from your description, so a new segment is a few minutes of work, not a week.

  2. 02

    Sell the problem, not the feature list

    Software buyers do not wake up wanting a dashboard. They want fewer manual steps, faster reports or happier customers. Lead with the problem you solve for their role, in their words, and keep features for the call. The knowledge base gives the AI the facts; your offering tells it what problem to lead with.

  3. 03

    Ask for a reply, not a demo

    A first email that asks for 30 minutes on a calendar asks too much from a stranger. Ask one easy question instead: is this on your list this quarter? A reply starts a conversation, and the meeting comes next. FirstSales get-reply campaigns are built around that short first email.

  4. 04

    Write to the account, not only the person

    Several people at one company may care about your product for different reasons. Reach two or three roles with different angles, and never send them the same email. FirstSales writes each email from the person's role, so the sales leader and the engineer each hear what matters to them.

  5. 05

    Protect the domain your product emails come from

    If cold email burns the domain your app uses for password resets and invoices, your customers feel it. Send cold email from separate domains and mailboxes, warm each one for 21 days and keep volume per inbox low. FirstSales gives you unlimited mailboxes and rotates sending across them.

  6. 06

    Follow up, and know when to stop

    Most replies come after the first email, not from it. Plan several follow-ups, each adding something new: a short example, a question, a different angle. Stop the moment someone answers or asks you to. FirstSales follows up on schedule and ends the sequence on any reply or opt-out.

Real pushback

What SaaS buyers say back, and what to write next.

Most cold replies are not a yes or a no. They are a test. Here are the ones SaaS teams hear most, and a better next email for each. The AI writer can draft these replies for you to approve.

  • “We already use a tool for that.”

    Good. Ask what they would change about it, then name the one thing yours does differently. Do not attack the tool they picked.

  • “Send me some info.”

    Send one short page, not a deck, and ask one question about their setup so the next reply is a conversation.

  • “No budget until next quarter.”

    Ask when planning starts and offer to show them something useful before then. Then follow up on that date.

  • “Our security review takes months.”

    Offer your security documents up front and ask who runs the review. Starting early makes the wait shorter.

  • “Talk to my team.”

    Ask for the name of the right person and permission to mention them. A warm handoff gets read.

  • “How did you get my email?”

    Answer plainly: where you found them and why you thought it fits. Then offer to stop writing. Honesty keeps your domain safe.

Before you launch

A SaaS outbound checklist

Run through this before your first campaign goes out. FirstSales covers most of it for you.

  • One clear segment and two or three buyer roles picked
  • Your website, docs and pricing added to the knowledge base
  • Cold email sent from separate domains, not your product domain
  • SPF, DKIM and DMARC set up on every sending domain
  • Warm-up running, growing over 21 days
  • Every contact checked, and Dirty contacts left out
  • First email short, plain and asking one easy question
  • Follow-ups that add something new each time
  • A meeting link ready for interested replies
  • Drafts read for the first campaign before they send
“One of the best email outreach tools I have ever seen in my 9 years of business experience. It has solved the problem of email outreach for my cold emails.”

Why SaaS teams switch

SaaS outbound: FirstSales vs a typical tool

Many tools send what you give them. FirstSales also finds the buyers, writes the emails and protects your mailboxes.

Good practice

Cold email to software buyers: the rules of the road.

B2B cold email is legal in many places when done with care, but the rules differ by country. These are general truths most teams follow.

  • Say who you areUse your real name, company and a real reply address. Never hide who sent the email.
  • Keep the subject honestThe subject line should match what the email is about. Fake replies and fake forwards break trust and many rules.
  • Make it easy to say noGive a simple way to opt out and honor it. FirstSales stops follow-ups when someone replies or opts out.
  • Write to a work role, about workReach people because of their job and write about a problem that job has. Many privacy rules lean on that link.
  • Privacy law applies to people at companiesIn the EU and the UK, a work email address of a named person is still personal data. Know why you hold it.
  • Only claim what is trueDo not promise results, security standards or customers you cannot show. The knowledge base keeps the AI to your real facts.

This is general information, not legal advice. FirstSales gives you the tools to send with care; you decide who to contact and you are responsible for following the rules where you and your prospects are.

Questions,answered plainly.

Can’t find yours? Write to us.

01Does cold email still work for SaaS?

Yes, when it is targeted and personal. A short email to the right role, about a problem that role has, still gets replies. A template sent to everyone does not. FirstSales is built for the first kind.

02Can FirstSales find SaaS buyers for me?

Yes. Describe the companies and roles you sell to and FirstSales builds the lead list. You can also upload your own list or CRM export. Every contact is checked before it sends.

03Will the emails understand a technical product?

They use what you teach them. Add your website, docs and pricing to the knowledge base and your offering. The AI writes from those facts, and you can read every draft before it sends.

04Should I send cold email from my product domain?

Most teams use separate domains for cold email, so the domain your app uses for logins and invoices stays clean. FirstSales gives you unlimited mailboxes, each warmed for 21 days.

05Can our whole sales team use one account?

Yes. Team members, mailboxes and workspaces are unlimited on every plan, and every reply lands in one shared inbox.

06What does it cost?

Plans start at $29/mo with warm-up, list cleaning and monitoring included. Try it for $1 for 3 days. No contract: cancel any time from your dashboard.

07Who is this not for?

If you want to blast bought lists or need someone to promise inbox placement, FirstSales is not your fit. It is for SaaS teams who send real, targeted cold email and want it to reach a person.

Outreach that keeps going after you log off.Leads, emails, follow-ups and replies, handled.

Install with AI

Your coding agent sets up the FirstSales CLI and skills for you.

Prompt for Claude Code

I'm setting up FirstSales (https://firstsales.io), an AI outbound sales platform: campaigns, contacts, a reply inbox, deliverability and lead signals. Help me get my workspace sending real, good emails end to end, from Claude Code.

Read these first so you know how FirstSales works:
- Developer docs and API: https://developer.firstsales.io
- CLI: https://www.npmjs.com/package/@firstsales.io/cli
- Skills for coding agents: https://github.com/firstsalesio/firstsales-skills (read README.md and GUIDE.md)

Setup
1. Install the CLI: npm install -g @firstsales.io/cli
2. Install the FirstSales skills:
   claude plugin marketplace add firstsalesio/firstsales-skills
   claude plugin install firstsales@firstsales
3. Ask me if I already have a FirstSales account. If not, send me to https://app.firstsales.io to sign up.
4. Ask me to create an API key under Settings → API → API Keys, with only the scopes we need.
   Never ask me to paste the key into this chat. Tell me to run this in my own terminal, so the key stays hidden:
   read -rs FS_KEY && firstsales auth login --api-key "$FS_KEY"; unset FS_KEY
5. Run `firstsales whoami` and tell me which workspace and organisation we are connected to.

Then ask me about my business: what I sell, who I sell to (roles, company size, countries), my best customers, and what I use today for outbound (tools, lists, mailboxes). Walk me through:
1. Teaching FirstSales my business: website, offer, proof points and case studies in the knowledge base, so the AI writes like someone who knows the product.
2. Connecting my sending mailboxes and checking my sending domain: SPF, DKIM, DMARC and warm-up. If anything is unhealthy, tell me the exact DNS record to add.
3. Bringing in contacts: import my CSV or CRM export into a clean list, remove duplicates and bad emails, and block domains I must never email (customers, competitors, my own).
4. Building my first campaign: the right list, senders, steps and timing. Write the sequence with me, show me the drafts, and do not launch until I say yes.
5. Setting up Signals if it fits: find people engaging with LinkedIn posts about topics my buyers care about, and turn them into leads.
6. Inviting my team and giving each person the right access.

Once campaigns run, show me how to work the reply inbox from here: which replies need an answer, draft responses in my voice, and move good conversations into deals. If I use Cal.com, connect it so follow-ups can offer my booking link (not the first email).

Throughout, as you learn about my business, proactively suggest and help create:
- Reply templates for the questions and objections my prospects are likely to raise, based on my product, site and codebase if you can see them.
- Campaign ideas and segments worth testing, with the reason for each.

Safety rules:
- Show every change as a dry run (--dry-run) first and wait for my yes. Never send emails, launch campaigns or delete anything without my yes.
- Tell me before anything that spends credits, and how many.

Be opinionated. If the docs give a sensible default, just use it. Don't make me choose between five options.
