AI SDR

An AI SDR that earns replies instead of burning your domain

Most AI SDRs just send more email faster. Tin Computer researches each account, reaches out when there's a real reason to, and protects your deliverability — outbound that reads like your best rep wrote it.

An AI SDR (sales development representative) is software that automates top-of-funnel sales: finding prospects, researching them, and sending personalized outreach to book meetings. Tin Computer works as an AI SDR that prioritizes quality over volume — it builds a tight ICP-matched list, enriches and researches each account, warms your sending domain, and personalizes every message, so replies go up instead of your domain reputation going down.

The AI SDR category got a bad reputation fast, and for a fair reason: most tools optimized for volume, flooded inboxes with thin personalization, and torched sender reputations. The work that actually books meetings — sharp targeting, real research, deliverability hygiene, genuine personalization — is the work Tin Computer focuses on.

How it works

  1. 01

    Define and build the ICP list

    It clarifies who actually buys, then builds and enriches a targeted list — not a 100,000-row dump you blast indiscriminately.

  2. 02

    Set up deliverability

    Domains, SPF/DKIM/DMARC, and inbox warmup are handled first, so messages land in inboxes rather than spam.

  3. 03

    Research, then personalize

    It researches each account and writes outreach with a real, specific reason for the message — the opposite of merge-tag spam.

  4. 04

    Send, follow up, and route replies

    It runs the cadence, follows up, and surfaces interested replies to you so a human closes — the agent handles the grind, you handle the conversation.

Aren't AI SDRs just spam with a UI?

That's the honest reputation of the category, and it's earned by tools that optimize for send volume. The thing that breaks outbound is generic messages at scale: low reply rates, blocked domains, annoyed buyers. Tin Computer is built the other way — tight targeting, real per-account research, deliverability hygiene, and human handoff on live replies. If 'AI SDR' means 'send 1,000 generic emails in 20 minutes,' that's exactly what this isn't. The point is fewer, better-aimed messages that earn replies.

Proof it ships

14× MRR in 57 days

Claw Messenger was flat — $40 MRR, four paying customers, most of them the founder testing his own product. We turned on Tin Computer on March 25 and walked away. Eight weeks later: $560 MRR, 66 paying customers, 125 commits shipped. The AI launched a referral program the same day a user asked if there was one, and a reseller tier the day after another customer said they wanted to resell.

What the AI SDR handles end to end

  • ICP definition and validation against your actual customers.
  • Lead-list building and enrichment from real signals.
  • Email infrastructure: domains, SPF/DKIM/DMARC, and inbox warmup.
  • Personalized cold email and LinkedIn sequences with real research.
  • Follow-up cadences, reply routing, and meeting booking.

Outbound as part of full-stack growth

Tin Computer isn't only an SDR — it's a growth agent that also runs SEO, ads, and CRO. That matters for outbound: it can align cold-email messaging with the landing pages it ships and the positioning it tests, so the whole funnel says the same thing. An SDR that knows what your site and ads are saying writes better outreach than one bolted on in isolation.

What good outbound numbers actually look like

Healthy cold outbound is measured by reply and meeting rates, not send volume. A well-targeted, well-researched campaign aims for low-single-digit positive reply rates and protects deliverability so it can keep sending. The failure pattern is the opposite: huge volume, sub-1% replies, rising spam complaints, and a domain that lands in junk within weeks. Tin Computer optimizes for the first profile — fewer, sharper messages that keep your domain healthy and your reply rate worth the effort.

  • Deliverability: messages landing in the inbox, not spam — the precondition for everything.
  • Positive reply rate: the real signal, driven by targeting and personalization.
  • Meetings booked: the outcome that matters, handed to a human to close.
  • Domain health: kept safe with warmup and sane volumes so the channel lasts.

Frequently asked questions

What is an AI SDR?
An AI SDR is software that automates early-stage sales — finding and researching prospects and sending personalized outreach to book meetings — then hands interested replies to a human to close.
Do AI SDRs actually work?
They work when they prioritize targeting, research, deliverability, and real personalization. They fail when they optimize for raw send volume. Tin Computer is built for the former, which is what produces replies rather than spam complaints.
Will an AI SDR replace human SDRs?
It replaces the repetitive grind — list building, research, sending, follow-up — so humans focus on live conversations and closing. The judgment and relationship work stays with people.
How is this different from other AI SDR tools?
Most optimize for volume. Tin Computer optimizes for reply quality: tight ICP lists, per-account research, deliverability hygiene, and human handoff — and it aligns outreach with the rest of your funnel.
Will it hurt my domain reputation?
Not if set up correctly, which it handles: dedicated domains, SPF/DKIM/DMARC, inbox warmup, and sane send volumes. Protecting deliverability is part of the job, not an afterthought.
Is AI SDR outreach legal?
Cold outreach is legal in most regions when you follow rules like CAN-SPAM and GDPR — accurate sender info, opt-outs, and legitimate targeting. Tin Computer follows these conventions; you remain responsible for your jurisdiction's rules.
How much does an AI SDR cost?
Tin Computer runs $49-$499/month depending on weekly task volume — far below the per-seat cost of dedicated AI SDR platforms, and it does SEO, ads, and CRO too. Start with a free scan.
How fast can it start booking meetings?
Infrastructure and domain warmup take a couple of weeks to do right before high-volume sending. Targeting and research begin immediately; first meetings typically follow within the first weeks.
