GeminiAn outbound agency runs the whole machine, not just the sequence.
Anyone can buy a sending tool. Targeting the right ICP, getting you into the inbox, and writing sequences that earn a reply is a different job. Here are the four things we own.
- Targeting
ICP and lead lists built on data, not a scraped dump
Bad lists kill outbound before the first send. We define your ICP with you (industry, headcount, role, trigger), then build clean lead lists from Apollo, Clay and LinkedIn Sales Navigator, enriched and verified so bounces stay low. The point is reaching the exact people who can buy, with the data to write a message that lands, not blasting ten thousand addresses and hoping.
See a typical setup - Deliverability
Inboxing infrastructure SPF, DKIM, DMARC and warmup
If you land in spam, nothing else matters. We set up the sending infrastructure properly: dedicated domains, SPF, DKIM and DMARC records, mailbox warmup, and inbox rotation so volume never burns your main domain. This is the unglamorous half of outbound that decides results, and the part most teams skip until their open rate quietly collapses.
See the method - Sequences
Multichannel cadences cold email plus LinkedIn outreach
One email is not a campaign. We build multichannel sequences across cold email and LinkedIn outreach, with an SDR cadence of spaced follow-ups, and we A/B test the copy, the subject and the angle. Messaging is written for your ICP and your offer, not a swipe file, so the reply actually starts a conversation worth your sales team's time.

Replies routed, qualified meetings on the calendar
A reply that dies in an inbox is a wasted lead. We wire the handoff: positive replies routed into your CRM (HubSpot, Pipedrive, Attio), meetings booked on your calendar, and the cadence tuned on what actually converts. We're an automation and growth agency first, so the outbound machine plugs into how your sales team already works instead of sitting beside it.

We treat outbound like infrastructure, not a spray.
Most outbound dies the same way: a tool bought, a scraped list, no warmup, everything blasted from the main domain, and the open rate collapses by week two. So we treat it like a system: the right ICP, deliverability set up to inbox, multichannel sequences tested against your offer, and every reply routed to your sales team.
- Audit · map your ICP, your offer, and whether cold outbound fits your sales motion at all
- Infra · dedicated domains, SPF/DKIM/DMARC, warmup and inbox rotation, set up to inbox
- Build · lead lists, multichannel sequences and copy, A/B tested against your ICP
- Run · route replies to your CRM, book qualified meetings, and tune the cadence on real data
We run outbound for ourselves.
We don't sell a guaranteed-meetings package. We run cold email and LinkedIn outreach for our own pipeline, so we set up the deliverability the way it actually inboxes: dedicated domains, warmup, inbox rotation, clean lists, and copy tested on real replies. That's exactly the half most outbound skips before the open rate quietly collapses.
- We run outbound for ourselves, so we set up the infrastructure the way it actually inboxes, not the way a sales deck describes it.
- Honest by default: list quality and deliverability decide results, so we'll tell you if cold outbound is wrong for your motion instead of selling you a sequence anyway.
- You leave owning it: the domains, the accounts and the playbook are yours, so your team can run the machine without us.
- No guaranteed-meetings gimmick. We're judged on a clean pipeline of qualified conversations, not an invented reply rate on a slide.
Outbound at the core, your sales stack around it.
We build the parts that turn cold outreach into a reliable pipeline, then connect them to how your sales team already works. Here's what a real outbound setup covers.
- Setup
ICP & lead lists
We define your ideal customer profile with you and build clean, enriched lead lists from Apollo, Clay and Sales Navigator, verified so your bounce rate stays low and your domain reputation safe.
- Setup
Deliverability setup
We configure dedicated domains, SPF, DKIM and DMARC, run mailbox warmup, and set inbox rotation so volume scales without burning your main domain or landing in spam.
- Setup
Cold email sequences
We write and ship cold email sequences with spaced follow-ups, personalised to your ICP, and A/B test subject lines and angles so the copy keeps improving instead of going stale.
- Setup
LinkedIn outreach
We add LinkedIn outreach to the cadence (connection, message, follow-up) so prospects hear from you on more than one channel, which lifts engagement over email alone.
- Setup
Tooling: Clay, lemlist, Instantly
We set up and run the stack that fits your volume: lemlist or Instantly for sending and warmup, Clay and Apollo for enrichment, so the machine is reliable and you own the accounts.
- Setup
CRM handoff & reporting
We route replies and booked meetings into your CRM (HubSpot, Pipedrive, Attio), and report on what's sent, opened, replied and booked, so you see the pipeline, not vanity metrics.
We pressure-test your outbound fit, you leave with a plan.
Before quoting anything, we take 60 minutes to look at your ICP, your offer, your deal size and your sales cycle. You leave with an honest read on whether cold outbound fits, what infrastructure to set up first, and what a realistic cadence looks like. Zero pitch, just a straight take on your prospecting.

- The deliverability infrastructure to set up first
- The ICP and channels worth targeting
- A frank take on where outbound won't help
How we run an outbound engagement.
Five steps, in order. We don't send at volume before deliverability is healthy, we don't launch without a clean ICP, and you own the domains and accounts at the end. Each step has a deliverable and you sign off before we move on.
- Step 1 · Outbound audit
Check whether cold outbound actually fits
We sit down with you and look at your offer, your ICP, your average deal size and your sales cycle. Half the value is an honest answer on whether cold outbound is the right channel: it works for a clear B2B ICP with a repeatable offer, and it's a bad fit for long relationship-led deals or pure B2C. We'd rather tell you that now than after three months of sending.
- Step 2 · Inbox infrastructure
Set up the infrastructure so you actually inbox
We register dedicated sending domains, configure SPF, DKIM and DMARC, warm up the mailboxes, and set inbox rotation so volume never torches your main domain. This is the part that decides whether your sequences are read or filtered, and it's where most outbound quietly fails. Nothing goes out at volume until the infrastructure is healthy.
- Step 3 · Lists & sequences
Build the lists and the multichannel sequences
We build clean, enriched lead lists from Apollo, Clay and Sales Navigator matched to your ICP, then write multichannel sequences across cold email and LinkedIn outreach with spaced follow-ups. Copy is written for your offer and A/B tested on subject, angle and CTA. The goal is replies that start a real conversation, not opens that go nowhere.
- Step 4 · Launch & route
Launch the cadence and route every reply
We launch the SDR cadence, monitor deliverability and reply quality daily, and route positive replies straight into your CRM (HubSpot, Pipedrive, Attio) with meetings booked on your calendar. We watch the numbers that matter, sent, opened, replied, booked, and adjust targeting and copy on what converts, not on a guess.
- Step 5 · Tune & hand over
Tune the machine, then hand you the keys
We keep tuning the ICP, the lists and the sequences on real reply data, and document the playbook so your team can run it. The domains and accounts are yours from day one. If you want to bring outbound in-house, we hand over the system and train your SDR. If you want us to keep running it, we talk about that separately.
We're judged on the pipeline that lands.
No guaranteed-meetings badge to display, so we lead with what matters: feedback from the teams whose outbound machine we built, and whether the qualified conversations kept coming after we tuned it. Our Trustpilot reviews come from those teams, not from a marketing deck.
- The domains and accounts live in your name, owned by your team
- Deliverability healthy before anything ships at volume
- Sequences A/B tested and tuned on real reply data
- Trustpilot reviews come from the teams we ran outbound for
The questions we get asked on repeat.
What does an outbound agency actually do?
An outbound agency builds and runs proactive B2B prospecting for you so you book qualified meetings without standing up an internal SDR team. We define your ICP, build clean enriched lead lists, set up the deliverability infrastructure (dedicated domains, SPF, DKIM, DMARC, warmup, inbox rotation), write and A/B test multichannel sequences across cold email and LinkedIn outreach, and route replies and booked meetings into your CRM. The point is a steady pipeline of real conversations, not a one-off blast that burns your domain.How much does outbound cost?
It depends on scope: setting up the infrastructure and one cold email sequence is nothing like running a multichannel machine across several domains with full CRM handoff. We don't throw out a flat package. We start with a free 60-minute audit to check whether cold outbound fits your motion, then quote a fixed scope. Sending tools like lemlist or Instantly and enrichment credits in Clay or Apollo you pay the vendors directly; we set up the usage so the bill stays predictable.Will outbound guarantee us meetings?
No, and anyone promising a fixed number of meetings is selling you a number, not a method. Results depend on your ICP, your offer and the market, and on two things we control tightly: list quality and deliverability. We can guarantee the machine is built right (clean lists, healthy inboxing, tested sequences, fast reply routing), and we'll be honest about what the market is telling us. We optimise for qualified conversations, not a vanity reply rate on a slide.How do you keep cold email out of spam?
Deliverability is half the job and the half most teams skip. We use dedicated sending domains so volume never touches your main domain, configure SPF, DKIM and DMARC correctly, warm up every mailbox before it sends at volume, and rotate inboxes so no single one gets overloaded. We keep lists clean and verified to hold bounce rates down, and watch open and reply signals daily. Good infrastructure is what keeps your sequences in the inbox instead of the spam folder.Which channels and tools do you use?
We run multichannel: cold email as the core, LinkedIn outreach layered into the cadence so prospects hear from you on more than one channel. On tooling, we set up what fits your volume: lemlist or Instantly for sending, sequencing and warmup, Clay and Apollo for enrichment and lead lists, LinkedIn Sales Navigator for targeting, and your CRM (HubSpot, Pipedrive, Attio) for the handoff. You own the accounts and domains, so the machine stays yours.When is cold outbound NOT the right fit?
When your sales motion is long and relationship-led (big enterprise deals that close on warm intros and events) or when you're pure B2C, cold outbound usually disappoints, and we'll say so in the audit. It also struggles without a clear ICP or a repeatable offer, because targeting and copy have nothing to anchor to. Outbound works best for a defined B2B ICP with a concrete value proposition and a sales cycle short enough that a booked meeting leads somewhere.How long before we see results?
Plan for a ramp. The first stretch goes to infrastructure: registering domains, configuring SPF, DKIM and DMARC, and warming mailboxes, which can't be rushed without hurting deliverability. Then lists and sequences go live and we start reading reply data. Outbound is a system you tune, so the early weeks are about getting the infrastructure healthy and the targeting right before volume scales. We'd rather inbox slower than burn your domain fast.Do you hand it over or run it for us?
Either, and the domains and accounts are yours from day one regardless. If you want outbound in-house, we set up the full machine, document the playbook, and train your SDR to run the cadence, the lists and the deliverability. If you'd rather we keep running it, we do that as a separate engagement. The point is you're never locked in: the system lives in your accounts, so you own the pipeline you build.
Stop blasting cold lists. Build the machine.
A 60-minute audit, an honest read on your outbound fit, a plan with the deliverability infrastructure baked in. If your team can run it in-house after setup, we'll hand you the playbook. If we're the right fit, we run it.
