You need outbound to work. Not just this quarter — as a reliable, scalable part of how your company generates pipeline over time.
The problem is that most outbound setups are designed for short-term activity, not long-term performance. Disposable domains, rotating inboxes, agencies that cycle infrastructure when deliverability dips, freelancers who can execute tactics but can’t explain why results stopped. These approaches produce motion. They rarely produce durability.
And the cost isn’t just bad results — it’s wasted time. Your time. Diagnosing why campaigns stopped working. Evaluating the next tool, the next agency, the next workaround. Starting over when something breaks.
Production-grade outbound is built differently. It treats email infrastructure, execution, and deliverability as a system that should get stronger over time — not weaker. It’s designed for companies that want outbound to reflect the kind of business they’re building.
Senders offers three services that work independently or together. Here’s how each relates to what you’re solving.
You want outbound producing pipeline — without building an internal operation to run it.
Outbound Operations is our full-service execution layer. We run outbound end-to-end: targeting, data sourcing, campaign construction, copy, testing, iteration, and scale — all on top of controlled sending infrastructure.
This is built for founders and CEOs who want pipeline without the overhead of hiring, training, and managing an outbound team from scratch. Your input shapes direction — new markets, new angles, new hypotheses — and our team handles implementation. The typical operational burden on your team is under one hour per week.
Everything we build is yours. Audiences, campaigns, copy, data, and structure live in tools your team can access in real time. Nothing is proprietary to us. If you eventually bring outbound in-house, you take everything with you. This is designed as an operational function you can own, not a black box you depend on.
Every member of our team has been running production-grade outbound for 4+ years. This isn’t a training environment. We’re not learning on your domains, your volume, or your reputation.
You have people running campaigns. You need the sending layer underneath to stop being a liability.
Maybe your team is already running outbound — or you have an agency handling it — but deliverability is inconsistent. Emails aren’t landing. Volume can’t scale without things breaking. The infrastructure underneath is fragile, and you’re not sure why.
Managed Email Infrastructure is the sending layer that sits underneath your campaigns. We operate the systems that determine whether your email actually reaches the inbox: aged domains deployed through controlled subdomain architecture, pre-warmed IPs with proven track records, tight DNS and authentication alignment, and continuous monitoring with active intervention when conditions change.
Your team — or ours, through Outbound Operations — still controls what gets sent: the tools, the copy, the audiences, the strategy. We manage the foundation underneath so they don’t have to think about warming, reputation, DNS configuration, or why Gmail suddenly started throttling their sends.
This matters most when your target audience includes enterprise buyers, regulated industries, or organizations with serious security postures. These environments actively filter recently spun-up infrastructure. Sender credibility isn’t optional — it’s the prerequisite for the conversation starting at all.
Something is wrong with your email and you need to know what’s actually broken — fast.
Not every problem requires handing over infrastructure. Sometimes you need experienced judgment: a clear diagnosis of what’s wrong, why it’s wrong, and exactly how to fix it.
Deliverability Consulting is a scoped, advisory engagement focused on diagnosing and correcting deliverability issues within your existing email system. It starts with a Diagnostic & Quick-Fix session — a 90-minute deep review of your authentication, reputation, sending behavior, and inbox placement signals. Many issues can be identified and resolved within that session. When they can’t, it establishes the foundation for targeted follow-on work.
You retain full ownership of your domains, IPs, email systems, and execution. We provide the expertise to figure out what’s actually happening and guide your team through the fix.
This is especially relevant if something broke recently — a sudden drop in placement, a deliverability crisis, a migration that went sideways — or if you’re about to raise and you need your email systems to be buttoned up.
Talk to our team. We’ll dig into what you’re working with, what’s not working,and what the right path forward looks like — whether that’s Outbound Operations, Managed Infrastructure, Deliverability Consulting, or some combination.No pitch deck, no demo loop. Just a real conversation about your setup andwhat would actually move the needle.
We work with companies from a wide variety of industries, predominantly in the B2B sphere, but we don't play favorites.
You want to move upmarket, but enterprise inboxes don’t trust new senders. We help you build the reputation that opens doors beyond SMB.

Founded by chef David Chang, Momofuku is a renowned culinary brand with a nation-wide presence, including restaurants and an online store with delicious goods. They ran into an issue with their email sending – high bounce rates and blocked sending. With hundreds of thousands of people on their email lists eager to stay informed, and an impeccable reputation to uphold, Momofuku wanted to nip this problem in the bud quickly.
Where many others see a problem, Andrew sees an opportunity. His work may center around product leadership at Google (and previously Meta), but his true calling is all about bringing brilliant change-makers together.
How it started: Andrew hosted small-scale dinners for a handful of people at the peak of the pandemic in NYC, to enable safe connections during the most isolating times. How it’s going: His events now count as many as 2,000 tech leaders each, and he has set up 100+ such parties for more than 15,000 people in the past couple of years. Andrew understands that if two minds are better than one, putting two thousand together, preferably in the same room, can make a profound difference.
Given the impact of his community-building efforts, people want him to be able to reach out – and email is often the best way to do so. So, we helped out a bit.

Senders Protocol works for every kind of email, including your newsletter and opt-in marketing campaigns. Setting up and keeping your sending systems in good shape will boost your inbox placement, and free up your time to focus on strategy and creative – although we can help with those, too.
If you’re using email as one of your main internal communication channels – sending out employee newsletters, company announcements, invites, etc – deliverability matters here, too. Our methodology focuses on safety across the board, so your internal emails can grow on pace with your team, and always land where they need to.
Time-sensitive, system-triggered emails are a crucial part of your customer experience, as well as your overall reputation. To make sure they arrive on time (every time) and land in the inbox, Senders optimizes your infrastructure and separates transactional from marketing or cold emails (using subdomains/IPs), preventing one from harming the other’s performance.
Our Deliverability expert will put your sending problems in perspective, determine the root cause, and suggest the best solutions to implement.
Production-grade outbound means treating email as a system that should get stronger over time — not weaker. It's the opposite of the disposable, cycle-and-replace approach that dominates most of the cold email market.
In practice, it means three things. First, the infrastructure underneath your outbound — domains, IPs, DNS, authentication — is built for durability. We use aged domains with real history and pre-warmed IPs with proven track records, not freshly registered infrastructure that has to earn trust from scratch. Second, execution is disciplined. Volume scales gradually and deliberately, campaigns are tested and iterated, and nothing happens that degrades the foundation your outbound runs on. Third, the system is designed so that every day of sending makes the next day's sending more effective. Reputation compounds. Credibility deepens. The infrastructure earns trust rather than burning through it.
The reason this matters for CEOs specifically is that the alternative — disposable infrastructure, agency churn, tools that produce short-term activity but long-term headaches — creates a hidden cost. You spend time diagnosing why campaigns stopped working, evaluating the next tool, starting over when something breaks. Production-grade outbound eliminates that cycle by building on a foundation that holds up as your company grows.
Honest answer: outbound is not instant, and anyone promising pipeline in week one is cutting corners that will cost you later.
Every new sending setup begins with a warmup period to establish the infrastructure's credibility with inbox providers. From there, sending volume ramps up gradually to build a stable behavioral profile. As a general guideline, most setups reach full operational run rate within about 30 days, and results begin to normalize from there.
The more important framing is this: outbound is iterative. Even if the first campaigns don't produce the exact results you're looking for, they generate real signal — what audiences respond, what messaging lands, what objections come up. That signal is how we dial things in. Some clients see strong results in the first month. Others need two or three months of iteration before the pattern clicks. Both are normal.
What we can tell you is that our approach — aged domains, pre-warmed IPs, production-grade execution — eliminates the most common reason outbound stalls: infrastructure failure. When the sending layer works, results come down to messaging and targeting, which are problems we can solve through iteration. When the sending layer doesn't work, nothing else matters because the email never reaches the inbox.
On the surface, we look similar. We run campaigns, build audiences, write copy, and generate leads. The difference is in what's underneath and how we think about our position in your setup.
Most agencies and freelancers operate on top of whatever infrastructure is available — often disposable domains, rotated inboxes, or shared sending pools provisioned through resellers. When deliverability dips, they cycle infrastructure and start over. This produces results for a while, but it's inherently fragile. And it creates a dependency: you can't see into the system, you can't take it with you, and when something breaks, nobody can explain why.
Senders is different in three ways. First, Outbound Operations runs on our Managed Email Infrastructure — aged domains deployed through pre-warmed IPs, controlled DNS, and continuous monitoring. Campaigns are built on a foundation designed to hold up under scrutiny, not just produce short-term activity. Second, everything we build is yours and fully portable. Audiences, campaigns, copy, data — all of it lives in tools your team can access in real time. There's no lock-in through proprietary systems or retained artifacts. Third, every member of our team has been running production-grade outbound for 4+ years. This is not a training environment. We are not learning on your domains, your volume, or your reputation.
The practical result: outbound that doesn't need to be rebuilt every few months because the foundation underneath it is built to last.
You can absolutely start with just one. Each service is designed to work independently.
The most common starting points depend on where you are:
The services are modular by design. Many clients start with one and add others as their needs evolve. Outbound Operations clients who build internal capacity often transition to Managed Email Infrastructure on its own. Deliverability Consulting clients who discover systemic infrastructure issues often move into Managed Email Infrastructure. The transitions are clean because the services are built to complement each other, not create dependency.
If you're evaluating this from an operations or systems perspective, our Sales & Revenue Operations page walks through how the services fit into existing tech stacks.
Outbound Operations is typically $3,600 per month. That covers the full scope: dedicated account management, audience building, data sourcing and cleaning, campaign construction, production-grade copy, A/B testing, iteration, strategic guidance, and a dedicated Apollo.io seat — all running on top of Managed Email Infrastructure.
When you break down what's included, that $3,600 covers the infrastructure that keeps you out of spam, the data you need, the copywriting and campaign setup, and ongoing optimization. Compared to the cost of hiring an SDR, engaging a traditional agency, and separately managing infrastructure and deliverability, it's a significantly more efficient path — with considerably less risk of things going sideways.
Managed Email Infrastructure and Deliverability Consulting are priced separately based on scope. For full pricing details on each service, see the individual service pages.
The way to think about the investment: outbound either works as a reliable, scalable pipeline source, or it becomes a recurring cost center that produces inconsistent results and endless troubleshooting. Production-grade outbound costs more upfront than the cheapest alternatives, but it eliminates the hidden costs — wasted time, agency churn, infrastructure failures, reputation damage — that make cheap alternatives expensive in practice.
Yes. The services are designed to be modular and to scale with your needs.
The most common progression we see: teams start with Outbound Operations because they want pipeline without building internal operations. As they grow and hire their own people, they transition campaign execution in-house while keeping Managed Email Infrastructure for the sending layer. The handoff is clean because everything was built in tools the team already has access to.
Another common path: a team starts with Deliverability Consulting because something is broken. The diagnostic reveals that the infrastructure issues are systemic, not one-off. They move into Managed Email Infrastructure to solve the root problem rather than repeatedly patching symptoms.
The key design principle is that no service creates lock-in that makes other services harder to adopt or harder to leave. Your domains are always yours. Your data and campaigns are always portable. The infrastructure layer is a service you can add, remove, or keep independently of what else you're doing.
This is one of the most important and least-asked questions in outbound. The short answer: production-grade outbound is designed to reflect your company's credibility, not undermine it.
The reason most outbound "looks like spam" isn't the copy — it's the infrastructure. When you send from freshly registered domains, rotate through dozens of look-alike sender identities, or use inboxes provisioned through third-party resellers, the sending pattern itself signals that you're trying to evade filtering. Enterprise inbox security systems are specifically designed to detect these patterns. Your email gets suppressed not because of what you said, but because of how you showed up.
Our approach is the opposite. We use fewer domains — aged, established, tightly controlled. We build deep sending history on each one. We maintain coherent authentication and consistent sending behavior. The result is a sender identity that looks like what it is: a real company running a real business program. Enterprise filters see consistency and coherence, not fragmentation and evasion.
This matters not just for deliverability but for brand perception. When your outbound looks professional — from a known domain, with proper authentication, with consistent sender identity — it reflects the kind of company you're building. When it looks like one of dozens of rotating identities, it doesn't.
If you're on Managed Email Infrastructure (which is included with Outbound Operations), we catch most issues before you notice them. Our monitoring tracks bounce classifications, rejection patterns, inbox placement signals, and enterprise gateway behavior continuously. When something deviates, we intervene — usually before the problem becomes visible in your campaign metrics.
When an IP starts underperforming, it gets replaced immediately without pausing your sending. When a domain shows early signs of reputation degradation, we diagnose the source and adjust. The system is designed for proactive intervention, not reactive firefighting.
If something more significant happens — a deliverability crisis, a blacklisting event, a sudden external change that affects placement — we have defined escalation protocols. We identify the cause, implement the fix, and communicate clearly about what happened and what we did. Nothing happens in a black box.
If you're not on a managed service and experience a crisis, our Deliverability Consulting engagement provides rapid triage. The Diagnostic & Quick-Fix session can be deployed as crisis support: fast identification of the root cause, clear remediation path, and guided recovery.
Tools like Apollo, Instantly, and Smartlead handle campaign execution — the front end of outbound. They let you build audiences, write sequences, and manage outreach. What they don't handle is the infrastructure underneath that determines whether your email actually reaches the inbox.
The core issue: these tools need to send from somewhere. If they're sending from fresh domains, inboxes provisioned through Google Workspace or Microsoft 365 resellers, or self-managed SMTP services, you're managing the reputation, warming, DNS, and deliverability problems yourself — whether you know it or not. At low volume, this works. As volume increases, infrastructure becomes the bottleneck, and the tool can't help you solve that.
Senders separates the two layers. Your team (or ours) can use Apollo, Outreach, or any campaign tool on the front end. Underneath, Managed Email Infrastructure provides the sending layer — aged domains, pre-warmed IPs, tight authentication, continuous monitoring — that those tools send through. The tool handles what to send. We handle whether it actually gets delivered.
The difference is most visible when you're targeting enterprise buyers or regulated industries, where inbox security systems actively evaluate sender credibility before they evaluate your message. In those environments, the sending layer is the prerequisite — and no campaign tool solves it.
That's exactly what Deliverability Consulting is for. It's a scoped, advisory engagement — not a long-term commitment or an infrastructure handover.
It starts with a Diagnostic & Quick-Fix session: a working review of your authentication, reputation, sending behavior, and inbox placement signals. We get into your systems and tell you what's actually causing the problem, what to fix first, what to leave alone, and how to verify the fix worked. Many issues — misconfigured authentication, DNS inconsistencies, workflow problems — can be identified and resolved within that session.
You retain full ownership of everything. We diagnose and guide; your team implements. If the issue turns out to be deeper than a quick fix, the diagnostic establishes the foundation for a scoped follow-on engagement — but you're never committed to more than you need.
This is a good starting point if you're not sure what's wrong or how big the problem is. It gives you clarity before you decide whether you need ongoing services or just a targeted correction.
