Cold outreach dies in the inbox because it reads like everyone else's template. Your AI SDR researches each prospect first, writes every email for one person, and stops the moment they reply.

## See your AI SDR at work

- **Builds the lead list.** Companies and contacts that match your ideal customer, each with a reason it fits.
- **Writes every email for one person.** Researched first, then written to that prospect, not a template with a name swapped in.
- **Knows your pitch.** Your offer, case studies and common objections live in your Drive, so every email tells the story the same way.
- **Asks before the first send.** New sequences wait for your yes. Approve, edit or skip each draft.
- **Reports on the pipeline.** Who was contacted, who replied and which conversations are ready for you.

## What it does

- **Builds lead lists**: Finds companies and contacts that match your ideal customer profile, with a reason each one fits.
- **Researches every account**: Reads the company and the person before a single word is written.
- **Writes one-to-one emails**: Each email is written for one prospect, grounded in that research.
- **Follows up on a set schedule**: Up to three touches per prospect, and it stops the moment they reply.
- **Hands off replies**: Interested replies come to you with the thread and research attached.
- **Reports on the pipeline**: Contacted, replied and booked, with numbers you can check.

## Set up in three steps

1. **Hire in one line.** "Hire an SDR. We sell payroll software to finance teams at 50 to 200 person companies."
2. **Connect your lead source.** Add Apollo or your CRM, or share a list. Cold email goes from dedicated sending domains, never your main inbox.
3. **Approve the first emails.** It sends a small first batch of drafts. You approve, edit or skip each one.

## Works with your tools

Apollo, HubSpot, Salesforce, Attio, Gmail, Google Sheets, Google Calendar, Slack, and 1,500+ more tools.

## Nothing is sent without your yes.

- **Drafts first**: New sequences wait for your approval before the first send.
- **Limits built in**: Daily caps and one-to-one writing are part of the product, not a setting.
- **Every thread visible**: Each prospect, email and reply sits on one board you can read any time.

## What it won't do

- **No cold calls**: It emails; it never cold calls from its phone number.
- **No blasts**: Daily caps and one-to-one writing are built in, not optional.
- **No cold email from your main domain**: Cold email goes from separate sending domains, never your company inbox.

## Three ways to run outbound

| | Doing it yourself | A sequencing tool | AI SDR |
|---|---|---|---|
| Researches each prospect | If time allows | No | Yes, before writing |
| Writes each email | You | Templates with fields | One to one |
| Follows up | You remember | On a timer | On a set schedule |
| Stops when they reply | You | Usually | Right away |
| Protects your main domain | No | Depends on setup | Separate sending domains |
| Asks before sending | n/a | No | Yes, by default |

## Things to ask it

- Here is our ideal customer profile: B2B SaaS, 11 to 50 people, US-based, selling to finance teams. Build a list of 25 target companies with the right contact at each and a one-line reason they fit.
- Research these 10 prospects and write a personalized opening email for each, referencing something real about their company. Keep each under 90 words.
- Design a 3-touch follow-up sequence for prospects who did not reply to the first email: timing, angle for each touch, and when to stop.
- Give me a pipeline report for this month: who we contacted, reply rate, positive replies, and which segments are responding best.

## Frequently asked questions

### What is an AI SDR?

An AI SDR is an AI sales agent that builds lead lists from your ideal customer profile, researches each prospect, writes personal outreach and follows up on schedule.

### Is an AI SDR the same as an AI sales agent?

Mostly. An AI sales agent is the broader term; an AI SDR focuses on the top of the funnel: finding the right people, starting the conversation and booking the meeting.

### Will it send from my company email?

Not for cold outreach. Cold email goes from dedicated sending domains with warmed-up mailboxes, daily volume caps and automatic handling of bounces and unsubscribes, so your main domain stays safe. For people who already know you, like customers and inbound leads, it can use your own connected mailbox within tight daily limits.

### Where do the leads come from?

Your own lists, your CRM, or a lead database like Apollo if you connect one. It researches each company and only writes to people who fit.

### What happens when a prospect replies?

Follow-ups stop at once and the reply lands in its inbox for a considered answer. When a call is next, it hands off to you with the thread and research attached.

### Will the emails feel like spam?

The approach is small batches of researched, individual emails. Volume caps are built in, so it can't blast even if asked.

### What does it cost?

You pay for the work, not the hire. Hiring is free. Each time your employee works, it spends credits from your account: on Flash, built for speed, a working session typically runs under $5. On Max, our deepest reasoning, the same session runs up to about $25. From there the cost depends purely on how much work you assign. Start free, no credit card needed, with 200 credits.
