AI SDR

An AI SDR that finds leads, writes every email and books the call.

FirstSales does the repeat work of a sales development rep: it finds people who fit, writes each one a personal email, follows up until they reply and offers your booking times. You approve what goes out and take the calls.

  • 01

    Finds leads that fit your ideal customer

  • 02

    Writes each email from company and role

  • 03

    Follows up until a reply, then stops

  • 04

    You approve before anything sends

The problem

Outbound needs a rep. Most teams can't keep one busy, or can't afford one.

Somebody has to find the leads, write the emails and chase the replies every single day. When that somebody is you, outbound is the first thing to slip. When it is a new hire, you wait months for them to ramp, and the work still stops when they are out.

Prospecting eats the day

Finding the right people, checking their email addresses and building a list takes hours before a single email goes out.

Generic emails get ignored

A template blasted to a list sounds like a template. Writing a real note to each person takes time nobody has.

Follow-ups fall through

Most replies come after a follow-up. When follow-ups depend on someone remembering, they stop the first busy week.

What changes

From empty calendar to calls you didn't chase.

Set the AI SDR up once. After that, the work runs every day and you step in only where a person helps.

  1. 01

    Tell it who you sell to

    Describe your ideal customer and your offer. Add your knowledge base so it knows your product, your proof and the questions buyers ask.

  2. 02

    Approve the first drafts

    Read what it wrote. Edit the tone or reject a draft. It learns your writing from emails you really sent.

  3. 03

    Take the meetings

    Replies land in one inbox and booked meetings land on your calendar. You show up, listen and sell. The AI SDR keeps the next list moving.

A day with an AI SDR

Your day on the left. The AI SDR's day on the right.

An SDR's job is mostly the same small tasks, again and again. Here is how a normal day splits once FirstSales takes the repeat work and you keep the calls only a person should make.

  1. Morning

    You:Open the approval queue with your coffee. Approve, edit or reject the drafts waiting for you.

    Your AI SDR:Sends the approved emails from your warmed-up mailboxes, spread across them with sending rotation.

  2. Late morning

    You:Take the calls already on your calendar. No prospecting before them.

    Your AI SDR:Looks for new leads that match your ideal customer, with AI search and Google Maps.

  3. Afternoon

    You:Read the replies that need a person: a real objection, a pricing question, a referral.

    Your AI SDR:Checks every new contact before it sends and leaves out the ones that would bounce.

  4. Evening

    You:Log off. Nothing waits on you to keep the pipeline moving.

    Your AI SDR:Writes tomorrow's first emails and follow-ups, each one from the contact's company and role.

  5. Overnight

    You:Sleep.

    Your AI SDR:Watches the health of every inbox each hour and keeps new mailboxes in their warm-up plan.

  6. Next morning

    You:New drafts and new replies are waiting in one place.

    Your AI SDR:Stops the sequence for anyone who replied or opted out, so nobody gets a follow-up by mistake.

Why it works

An SDR's whole job, done the same way every day.

A good SDR is steady more than clever. FirstSales is steady by design: it does not get tired, skip follow-ups or forget a lead.

  • Leads that fit

    AI search and Google Maps find people who match your ideal customer, not a bought list of strangers.

  • Personal emails at volume

    Each email is written for one person, from their company and role. No mail merge with a first name.

  • Follow-ups that never slip

    It follows up until the person replies and stops the moment they reply or opt out.

  • You stay in control

    Drafts wait in Needs approval until you approve, edit or reject them. Turn on AI Autopilot when you trust it.

  • Your inboxes stay healthy

    Every mailbox warms up for 21 days, every contact is checked before it sends and each inbox gets a health grade.

  • Meetings, not just replies

    Meeting campaigns offer your booking times, so an interested reply can turn into a call on your calendar.

Five jobs yourAI SDR does for you

Each job is a step in one campaign workflow: Contact Harvester, Segmentation, Email Scheduler, Email Drafter, Content Approval and Email Sender. You can see every step, change it and check what it did.

  1. Prospecting

    Find people who fit, and check them first

    Tell FirstSales who you sell to. AI agents look for matching people with AI search and Google Maps, then check every address before it is used. Contacts that would bounce are left out.

    • AI search and Google Maps. Two ways to find people, from software teams to local businesses.
    • Every address checked. Format, mail server and mailbox, before anything sends.
    • Dirty contacts skipped. Disposable and risky addresses never reach a campaign.
  2. Writing

    A personal email for every person on the list

    The Email Drafter writes each first email from the contact's company and role. Your knowledge base, offerings and writing profile tell it what you sell and how you sound.

    • Knowledge base. Your product, your proof and your answers, in one place it reads from.
    • Writing profile. Learns your tone from real emails you sent.
    • Get-reply campaigns. A short first email with one easy question to start a conversation.
  3. Approval

    Nothing sends until you say so

    New drafts wait in Needs approval. Read each one, then approve, edit or reject it. When you trust what it writes, turn on AI Autopilot and let approved campaigns run on their own.

    • Approve, edit or reject. One click per draft, with the full email in front of you.
    • AI Autopilot when you're ready. Hand more over once the drafts read like you.
    • Template mode. Prefer your own words? Send your template with no AI writing.
  4. Follow-up

    Follow up until they reply, then stop

    Each follow-up is written for the same person, not copied from the first email. The sequence stops on a reply or an opt-out, so nobody gets chased after they answer.

    • Stops on reply. A reply ends the sequence for that person at once.
    • Stops on opt-out. An unsubscribe is respected on every campaign.
    • One inbox for replies. Unibox brings replies from every mailbox into one list.
  5. Booking

    Turn an interested reply into a meeting

    Connect Google Calendar or Outlook Calendar. In a meeting campaign, FirstSales offers your booking times, and with AI Autopilot on it answers interested replies for you.

    • Google or Outlook Calendar. Connect the calendar you already use.
    • Your booking times. Offered in the email, so the next step is easy.
    • Answers interested replies. With AI Autopilot on, it replies to people who want to talk.
Who does what

The AI does the steps. You make the calls.

Every lead moves through the same six stages. The tag on each stage shows who owns it. You can move the line: turn on AI Autopilot to hand more over, or keep every email in the approval queue.

  1. AI SDR

    Find

    Builds a list of people who fit your ideal customer and checks each address.

  2. AI SDR

    Write

    Drafts a first email for each person from their company and role, in your tone.

  3. You

    Approve

    You read the drafts in Needs approval. Approve, edit or reject each one.

  4. AI SDR

    Send and follow up

    Sends from your mailboxes and follows up until the person replies.

  5. You

    Reply

    Replies land in Unibox. You answer the ones that need a person.

  6. AI SDR

    Book

    In a meeting campaign, offers your booking times so the meeting lands on your calendar.

Prefer to write every email yourself? Template mode sends your own words with no AI writing at all. You still get lead finding, contact checks, warm-up, follow-ups that stop on a reply and one inbox for every answer.

See it in the app

Every step of your AI SDR, in plain view.

This is the real FirstSales app with sample data. Open a campaign and you see each lead, each draft, each send and each reply. No black box.

  • Each lead and why. See the contacts it found and the check status for each.
  • Each draft before it sends. Read, approve, edit or reject in the approval queue.
  • Each reply in one place. Unibox shows every answer from every mailbox, next to the email that earned it.
  • Each inbox's health. Warm-up score and health grade for every mailbox.
Plain guide

What an AI SDR is, and what it is not

A short, honest guide for founders and sales leads deciding whether to hand outbound to software.

  1. 01

    An AI SDR does the repeat work

    A sales development rep finds leads, writes first emails, follows up and books meetings. An AI SDR does those same steps with software. It does not replace the person who closes the deal.

  2. 02

    It works best with a clear offer

    The AI writes from what you tell it. A clear ideal customer, a clear problem and a clear offer give it something true to say. A vague offer gives you vague emails.

  3. 03

    Start with approval on

    Read the first drafts before they send. Fix the tone, add proof to your knowledge base and reject anything off. Turn on AI Autopilot once the drafts read like you, not before.

  4. 04

    Give it a narrow first list

    Start with one clear group of people: one industry, one role, one problem. A narrow list makes it easy to see what works, fix what doesn't and then widen the search with AI search or Google Maps.

  5. 05

    Judge it on conversations

    Opens are a weak signal. Count replies from the right people and meetings booked. FirstSales shows sends, replies, bounces and meetings per campaign, so you can see which offer and which list earn real conversations.

  6. 06

    Deliverability still matters

    A great email in spam does nothing. FirstSales warms up every mailbox for 21 days, checks each contact before it sends and grades each inbox, so the emails have a fair chance to be seen.

  7. 07

    Keep the human parts human

    Hard objections, pricing talks and the call itself belong to you. The AI SDR clears the path so you spend your time there.

Before you switch on

your AI SDR

A short setup that makes every email better. Do it once, before the first campaign, and update it as you learn what your buyers answer.

  • Write one sentence on who you sell to
  • Write one sentence on the problem you solve
  • Add your offer and price to Offerings
  • Add product facts and proof to the knowledge base
  • Connect your mailboxes and let warm-up start
  • Check that SPF, DKIM and DMARC pass
  • Connect Google Calendar or Outlook Calendar
  • Pick a goal: get replies or book meetings
  • Approve the first drafts yourself

01What is an AI SDR?

An AI SDR is software that does the repeat work of a sales development rep: finding leads, writing first emails, following up and booking meetings. FirstSales does these steps for you while you approve what goes out and take the calls.

02Will the emails sound like a robot wrote them?

Each email is written for one person from their company and role, using your knowledge base and offerings. The writing profile learns your tone from emails you really sent. You read and approve the drafts before they go out.

03Can I check emails before they send?

Yes. New drafts wait in Needs approval, where you approve, edit or reject each one. Turn on AI Autopilot only when you are happy with what it writes.

04Where do the leads come from?

AI agents look for people who match your ideal customer with AI search and Google Maps. You can also import your own contacts. Every contact is checked before it sends, and Dirty contacts are skipped.

05Can it book meetings for me?

Yes. Connect Google Calendar or Outlook Calendar and run a meeting campaign. FirstSales offers your booking times in the email, and with AI Autopilot on it answers interested replies.

06Does an AI SDR replace my sales team?

No. It does the repeat work so your people spend time on real conversations. Objections, pricing and the call itself stay with a person.

07Will sending more email hurt my domain?

FirstSales protects the mailboxes it sends from. Each new mailbox warms up for 21 days in three phases, every contact is checked before it sends, SPF, DKIM and DMARC are checked when you connect, and each inbox gets a health grade watched every hour.

08How much does it cost?

Plans start at $29/mo with unlimited mailboxes, warm-up and team members. You can try it for $1 for 3 days and cancel anytime from your dashboard.

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.
