The Instantly agency.Cold email that lands.

Instantly scales cold outreach, but volume on a cold domain just lands you in spam. We build the infrastructure first (domains, SPF/DKIM/DMARC, warmup, rotation), run the campaigns and sequences, and watch deliverability so replies reach real inboxes.

What we do

An Instantly agency builds the infrastructure, not just the campaign.

Anyone can write a sequence. Standing up domains, warming inboxes, sizing rotation and keeping deliverability healthy at scale is a different job. Here are the four things we own.

Method · 4 stages

We run Instantly like infrastructure, not a blast tool.

Most cold email programs die the same way: a fresh domain, no warmup, a bought list, a thousand sends, and the domain in the spam folder by week two. So we treat Instantly like infrastructure: domains authenticated, inboxes warmed, lists verified, rotation sized to volume, and deliverability watched the whole time.

  • Audit · map your ICP, your offer, and whether cold email is even the right channel
  • Infra · domains, SPF/DKIM/DMARC, warmup and inbox rotation, before any send
  • Launch · campaigns, sequences and verified lists, scaled by warmed accounts
  • Enable · hand over the playbook, the API hooks and the reporting your team needs

Differentiator · no badge

We run cold email on Instantly ourselves.

We don't sell a partner tier. We run outbound on Instantly for our own pipeline, so we set it up the way deliverability actually works: domains authenticated, inboxes warmed, lists verified, rotation sized, and placement watched. That's exactly what's missing when a cold email program ends at importing a list and hitting send.

  • We run cold email on Instantly ourselves, so we set up the infrastructure the way deliverability actually works, not the way a demo suggests.
  • Deliverability first by default: we wire warmup, rotation and verification so volume doesn't torch your sender reputation.
  • You leave autonomous: the campaigns, the API hooks and the reporting live in your account, so your team owns it without us.
  • No badge to sell. We're judged on whether replies land and your domains stay healthy after we leave, not on a partner tier.

What we set up

Instantly at the core, your cold email stack around it.

We configure the parts that turn cold email into a reliable channel, then connect them to how your team already sells. Here's what a real setup covers.

  • Setup

    Domains, SPF/DKIM/DMARC

    We register and configure sending domains and mailboxes with the right DNS authentication, so providers trust your mail before the first cold email goes out.

  • Setup

    Email warmup

    We run Instantly warmup on every account until it has a real sending history, then keep a warmup baseline running so the inboxes stay trusted as volume climbs.

  • Setup

    Inbox & sending rotation

    We connect unlimited email accounts and set sending rotation with sane per-account limits, so volume scales across warmed inboxes instead of stressing a few.

  • Setup

    Campaigns, sequences & spintax

    We build the campaigns and multi-step sequences, write the copy for your ICP, and use spintax to vary each send, so messages read like a human wrote them.

  • Setup

    B2B lead finder & database

    We use the Instantly lead finder and B2B database to build targeted lists, then verify them, because a clean list protects deliverability and beats a bigger dirty one.

  • Setup

    Unibox, API & CRM sync

    We centralise replies in the Unibox and wire the Instantly API to your CRM, so positive intent reaches your reps and reporting reflects pipeline, not vanity opens.

Free audit · 60 minutes

We pressure-test your outbound, you leave with a plan.

Before quoting anything, we take 60 minutes to look at your ICP, your offer, your list sources and your current deliverability. You leave with an honest read on whether cold email fits, what infrastructure to build first, and what reply rate is realistic. Zero pitch, just a straight take on your outbound.

  • An honest read on whether cold email is your channel
  • The domains, warmup and rotation to set up first
  • The campaigns and lists worth running
  • A frank take on the deliverability and compliance risk

Our approach

How we run an Instantly cold email setup.

Five steps, in order. We don't send before the domains are warmed, we don't scale before the reply rate proves out, and your team owns it at the end. Each step has a deliverable and you sign off before we move on.

  1. Step 1 · Outbound audit

    Check whether cold email is even your channel

    We sit down with you and look at the real picture: your ICP, your offer, your list sources, and what you've sent before. We check whether cold email fits, because for some markets it doesn't, and a great setup against a weak offer still flops. Half the value is telling you honestly where Instantly helps and where it won't, so you don't pour budget into a channel that won't convert for you.

  2. Step 2 · Build the infrastructure

    Domains, warmup and rotation before a single send

    We register the sending domains, set up the mailboxes, configure SPF, DKIM and DMARC, and connect unlimited email accounts in Instantly. Then we run warmup until the inboxes have a real history and set inbox rotation with sane per-account sending limits. Nothing goes out cold. You scale by adding warmed accounts, never by pushing volume through inboxes that aren't ready.

  3. Step 3 · Launch the campaigns

    Sequences and verified lists that earn replies

    We build the campaigns and multi-step sequences in Instantly, write the angles for your ICP, and use spintax so each send reads differently. We pull targeted lists from the lead finder and B2B database, then verify them before sending, because list quality decides results more than copy does. We start small, read the reply rate, and scale the winners across your warmed inboxes.

  4. Step 4 · Watch deliverability

    Keep you in the inbox, not the spam folder

    We treat inbox placement as ongoing ops, not a one-time setup. We monitor warmup, run placement tests, watch blacklists and bounce rates, and pause accounts before a bad list damages a domain. Replies centralise in the Unibox so nothing slips. When placement drops, we catch it before your reply rate does and fix the cause, whether it's the list, the copy or a domain that needs to cool down.

  5. Step 5 · Enable & hand over

    Hand you the playbook, then get out of the way

    We connect the Instantly API to your CRM so replies and positive intent reach your reps, set up reporting on reply rate and pipeline, and train your team to run campaigns without us. The setup lives in your account, not ours. If you want to go deeper on the automation around it, our wider work covers that. If you want us on call as you scale to more domains, we talk about that separately.

Proof · what the teams say

We're judged on the replies that land.

No partner badge to display, so we lead with what matters: feedback from the teams whose Instantly setup we built and ran, and whether their domains stayed healthy and replies kept coming after we left. Our Trustpilot reviews come from those teams, not from a marketing deck.

  • The campaigns and API hooks live in your account, owned by your team
  • Domains warmed and lists verified before any volume goes out
  • Deliverability watched, accounts paused before a domain burns
  • Trustpilot reviews come from the teams we ran cold email for

FAQ · Instantly agency 2026

The questions we get asked on repeat.

  • What does an Instantly agency actually do?
    An Instantly agency builds the cold email infrastructure behind your outreach and runs the campaigns, instead of leaving you with a login and a learning curve. We set up sending domains with SPF, DKIM and DMARC, connect unlimited email accounts, run warmup, configure inbox rotation and sending limits, build the campaigns and sequences, verify your lists, and watch deliverability. The point is replies landing in real inboxes while your sender reputation stays intact, not a tool you bought and never scaled.
  • How much does an Instantly cold email setup cost?
    It depends on scope: a domains-and-warmup setup is nothing like running multi-client campaigns across dozens of inboxes with CRM sync. We don't throw out a flat package. We start with a free 60-minute audit to find whether cold email fits your offer and what infrastructure you need, then quote a fixed scope. The Instantly subscription itself you pay Instantly directly; we set up the accounts and sending limits so the cost stays predictable as you scale.
  • Will my cold emails actually land in the inbox?
    We do everything to put them there, but no honest agency guarantees the inbox, and we won't. Deliverability is a moving target that depends on warmup, domain authentication, list quality, copy and how providers feel that week. We configure SPF, DKIM and DMARC, run real warmup, verify lists, keep per-account sending limits sane and monitor placement, which is what gives you the best shot. Cold email always carries some spam risk, so we tell you that up front rather than promising numbers we can't control.
  • How does Instantly warmup and inbox rotation work?
    Warmup builds a sending account's reputation by exchanging positive interactions across a network before you send any cold email, so providers see a real history instead of a cold domain blasting strangers. Inbox rotation spreads your campaign volume across many warmed accounts so no single inbox exceeds safe sending limits. We connect unlimited email accounts in Instantly, warm them, and set rotation to your real volume, so you scale by adding accounts, not by overloading the ones you have.
  • Can you connect Instantly to our CRM and tools?
    Yes, that's where the campaign becomes pipeline. We use the Instantly API to push replies and positive intent into your CRM, so your reps work qualified conversations instead of digging through an inbox. We centralise everything in the Unibox first, then sync the signals that matter. Reporting is set up on reply rate and pipeline rather than vanity opens, so you can see what's working and double down on it, not just admire an open-rate chart.
  • Is cold email with Instantly legal and compliant?
    It can be, and we set it up to stay on the right side, but it's your responsibility to follow the rules in the markets you target. Cold email carries compliance risk: rules like GDPR in the EU, CAN-SPAM in the US and similar laws elsewhere govern who you can email and how. We configure one-click unsubscribe, honour opt-outs, and keep complaint rates low because that's also how you protect deliverability. We'll flag where your use case looks risky rather than pretend the rules don't apply.
  • When is Instantly NOT the right fit for us?
    When cold email is the wrong channel for your market, no setup saves it. If your ICP is tiny and reachable by hand, or you sell to people who never read cold email, the volume play doesn't pay off. Cold email also carries deliverability and compliance risk, and list quality decides results more than copy. If you can't get clean, targeted lists, you'll struggle no matter the tool. We'll tell you that in the audit instead of selling you a setup that won't convert.
  • Do you train our team or just set it up?
    Both, and the handover is where it sticks. A setup nobody can run gets abandoned the first time deliverability dips. We build the infrastructure and the campaigns, then train your team to run sequences, read the reporting, manage the Unibox and keep warmup and rotation healthy. The whole thing lives in your Instantly account, not ours. If you want us on call as you add domains and clients, we scope that separately rather than locking you into a retainer you don't need.
