The Service:

Outbound Operations is our full-service execution layer for teams that want
outbound run well, quickly, and without hidden risk.

Where Managed Email Infrastructure provides a stable sending foundation, Outbound Operations is how that foundation is actively used: audiences arebuilt, campaigns are launched, tested, adjusted, and scaled, without introducing fragility or operational drag.

Dedicated account management (a named operator, not a ticket queue)

Every person on our team has been running production-grade outbound for 4+ years. This is not a training environment, and we are not learning on your domains, your volume, or your reputation. We build our combined expertise into every strategy we deliver to you.

Concierge setup and ongoing maintenance

We compress the operational burden on your team to under one hour per week. Your input setsdirection, but we handle implementation.

Fully managed Apollo execution (seat, targeting, campaigns, iteration)

We do not lock you in through opaque systems or propri-
etary complexity. All outbound lives in tools your team can access at anytime. Audiences, campaigns, copy, and performance are fully visible and portable (you can transfer it all to your internal workflows at any time).

Unlimited access to audiences, campaigns, and data

We do not “cap” audience count or campaign count – but we do insist on gradual scaling. You can test parallel motions, explore new segments, or increase throughput without changing the operating model.

Plus:

Ongoing strategic guidance on targeting, sequencing, and volume

Support for increased volume and multiple senders within safe bounds

Continuous A/B testing without destabilizing the system

Advanced data cleaning and validation pre-send

Production-grade copy execution built to communicate your credibility

Why This Matters:

Outbound often breaks not because the idea was wrong – but because execution introduces hidden fragility. Over-complex workflows, opaque agency setups, and uncontrolled testing quietly degrade reputation and learning over time.

Outbound Operations is designed to move fast without breaking the system underneath it, so results compound instead of resetting.

This Is For Teams That:

Want outbound that remains viable months and years into scale

Need execution speed without sacrificing system integrity

Cannot afford domain churn, account churn, or reputation erosion

Want outbound to behave like an operational function, not a gamble

If you want outbound that holds up as expectations and volume increase, this is how it gets run.

Momofuku

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.

  • Momofuku reached out to Senders to run a diagnostic test on their sending infrastructure and find the root cause
  • Senders deliverability experts discovered an issue with their DMARC, which was preventing emails from being sent, as their WordPress wasn't aligned with their SPF
  • Senders provided the most effective solution helping Momofuku restore safe sending, and suggested next steps to ensure everything keeps running smoothly on their end
  • The client reported that Senders helped identify the problem and got them back on track 

Andrew Yeung

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.

  • Andrew came across deliverability issues that prompted him to get in touch with Senders and look into the best possible solutions
  • The Senders team made the necessary domain configuration adjustments, with a focus on the domain’s email authentication settings to enhance security and deliverability
  • The SPF record was updated to include “Brevo” (Sendinblue) to strengthen authentication and reduce the chance of landing emails into spam
  • The DMARC policy update enabled better readability of DMARC reports for human analysts, which is essential for preventing email spoofing and phishing
  • Senders fixed the missing DKIM setup with Google, so that it now shows the email hasn’t been tampered with in transit
  • As a result, the client now has better, more stable email deliverability and security

Myrina.ai

Stands out as a trailblazer in empowering women entrepreneurs through technology and a supportive community.

Myrina.ai offers a cutting-edge range of AI-powered SaaS marketing and sales tools that cater specifically to female entrepreneurs and women-led businesses. Myrina.ai enables users to automate marketing and sales, while helping them scale their authentic selves while saving time and boosting conversions. Their Myrina’s Army community fosters a supportive platform that champions female entrepreneurs and their values, empowering them to conquer barriers and achieve their business goals. The company's dedication to providing not only top-notch technological solutions but also a platform for networking and mentorship underscores their commitment to fostering success among women in the entrepreneurial space.

Naturally, they wanted to make sure their email sending infrastructure was set up correctly to protect their reputation and successfully reach their recipients. Our deliverability team worked with the client’s team on:

  • Aligning the client’s three domains with Amazon to make sure they are compatible and optimized in order to integrate with Amazon’s system
  • Setting up a proper DMARC policy to protect their domains against unauthorized use and phishing scams
  • Enhancing email deliverability as well as security, so that each email sent from these domains can be properly authenticated and more likely to land in the right inbox
  • As a result, the client can protect the reputation of their business and domains, while safely sending out their email campaigns

Physician’s Choice

Sometimes the sheer number of options of any product can be daunting – how on earth do you pick the right one? This is especially true with supplements, as we can find them just about anywhere, but we can rarely understand a third of the ingredients listed. Unlike most, Physician’s Choice provides supplements with pure, potent ingredients that work. No fillers or “proprietary” blends with unidentified ingredients. They do the research, so you don’t have to.

  • The client’s team spotted issues with DMARC failures in Google Postmaster
  • The Senders deliverability team worked with the client to update the DMARC configuration to enable report collection
  • The client is now able to obtain detailed reports to diagnose the exact causes of the failures and prevent them in the future with proper DMARC setup

Use Cases

It’s more than just keeping your emails out of spam – our approach protects your domain reputation, while helping you grow your sales pipeline with valuable, relevant prospects. Our infrastructure + methodology enable you to scale your cold campaigns safely and focus on engagement and closing deals. 

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.

FAQ

What does Senders actually do when you say “Outbound Operations”?

Outbound Operations is our full-service execution layer. We run outbound end-to-end: audience identification and building, campaign construction, copy, testing, iteration, and scale – all running on top of our Managed Email Infrastructure service (the dedicated sending layer we operate for our clients).

That means your team is not managing domains, warming IPs, debugging deliverability, or assembling campaigns from scratch. We handle the operational weight so you can focus on evaluating results and pointing us toward new opportunities.

This typically centers on cold email, but depending on the engagement, we also coordinate LinkedIn outbound, align with other parts of your marketing stack, and execute one-off pushes tied to your broader go-to-market motions. Some of these are included; some are priced separately depending on scope.

The distinction from “we just send emails for you” is important. We treat outbound as an operational function – not a bag of tactics – and we build it to remain stable, transferable, and understandable as it scales.

What does day-to-day execution look like once we’re live?

Think of it like sitting in the passenger seat. You point at new markets, new angles, new opportunities – and our team does the work of making it happen. We assemble the audience, pull the data together, write and refine the copy, get your approval, and launch.

The typical rhythm looks like this: we send you new copy and targeting for review, you approve it, and by the time you get on your weekly check-in call with our team, the audiences are loaded and the copy is in the sequence. Each week you get an export of everyone who replied with interest. Reporting lives inside Apollo – replies are categorized (Interested, Not Interested, etc.) so you can see exactly where things stand. On the call, we adjust targeting, tweak copy, and explore new audiences based on what the data is telling us. Decisions get made through a direct line to your account manager – not a ticket queue.

Behind the scenes, there’s a layer of work you don’t see but benefit from con- stantly. Our Outbound Operations team interfaces with our backend infrastructure team to check on new sender warmups, ramp-ups, and deliverability signals.

They relay and explore specific issues that come up. They talk with other members of our team to gather insights and feedback – everyone at Senders has direct experience with outbound motions. That invisible work is what keeps everything running smoothly as volume and complexity grow.

What tools do you use, and do we get access to everything?

Apollo.io is the primary surface area you interact with. That’s where audiences, campaigns, copy, and performance data live – and you have full access to all of it. No black boxes, no proprietary dashboards you can’t see into.

On the backend, we run a separate layer of tools that manage deliverability, infrastructure health, warming, and sending optimization – this is our Managed Email Infrastructure service at work. We don’t burden you with the details of which IP pool is active or which warming protocol is running on a given day – that’s our job.

The way to think about it: everything above the sending layer is fully transparent and yours. Everything below it is handled by us so you don’t have to think about it. You get the benefit of a professionally managed backend without the operational overhead of understanding or maintaining it.

How is this different from hiring a cold email agency?

On the surface, we look and feel similar to a cold email agency. We run campaigns, write copy, build audiences, and generate leads. The difference is in how we think about our position in your setup.

Most agencies operate on top of whatever infrastructure is available – often disposable domains, rotated inboxes, or shared sending pools. When deliverability dips, they cycle infrastructure and start over. The result works for a while, but it’s inherently fragile and creates lock-in through opaque systems that are hard to internalize or diagnose.

Outbound Operations runs on our Managed Email Infrastructure – your aged domains deployed through our pre-warmed IPs, controlled DNS, and continuous monitoring. That means campaigns are built on a foundation designed to hold up under scrutiny, not just produce short-term activity.

Beyond infrastructure, everything we build is yours and fully portable – we don’t create lock-in through opaque systems or retained artifacts. Every person on our team has been running production-grade outbound for 4+ years. This is not a training environment. We are not learning on your volume, your domains, or your reputation.

Why not just hire an SDR or build an in-house team?

There’s nothing wrong with having an SDR – and many of our clients do. The question is really about how much of the outbound function you want to centralize and how you want it structured.

Some teams centralize outbound through us and distribute interested replies to their SDRs for follow-up and closing. Others run multiple SDRs with their own outbound channels, using our infrastructure underneath. Some don’t need an SDR function at all – they’re doing founder-led sales and need a team that can move fast without building an internal operation from scratch.

Where in-house teams typically hit a wall is on the backend. An SDR can manage the frontend – targeting, messaging, follow-up – but scaling the sending infrastructure without running into spam, reputation degradation, or deliverability problems is a different skill set entirely. That combination of expert execution on top of production-grade infrastructure is what Outbound Operations provides.

If you already have an SDR in a good position and they’re handling the frontend well but struggling to scale volume safely, you may not need full Outbound Operations. Our Managed Email Infrastructure service can sit underneath their existing workflow and make sure the sending layer holds up as they grow.

What makes your team different from freelancers or contractors?

Freelancers and contractors can often handle the tactical side of outbound – writing sequences, pulling lists, setting up campaigns. Where they consistently run into trouble is at scale.

To send more volume, a freelancer typically needs to spin up more domains, rotate more inboxes, or cycle infrastructure when things degrade. These are the patterns that enterprise-grade filtering systems are specifically designed to detect and penalize. It works until it doesn’t, and when it breaks, recovery is slow and expensive.

Our Outbound Operations runs on top of Managed Email Infrastructure – a carefully managed shared sending layer with pre-warmed IPs and proven reputation that a freelancer simply doesn’t have access to. That’s the difference between scaling safely and scaling until something breaks.

Beyond the technical layer, our team thinks at the system level, not just the campaign level. Decisions are informed by years of direct exposure to real sending constraints across industries and environments – not templates or theory.

And importantly, nothing we build is proprietary to us. Your campaigns, data, and structure are fully portable from day one.

What kinds of companies use Outbound Operations?

Our clients tend to be companies in high-trust, high-scrutiny industries – healthcare, fintech, cybersecurity, legal, HR tech, and enterprise SaaS among them. These are environments where sender credibility and domain reputation materially affect whether email reaches the inbox at all.

We work with hyperscalers and soon-to-be hyperscalers – companies backed by Y Combinator, Sequoia Capital, Founders Fund, Index Ventures, and Thrive Capital, among others.

The common thread isn’t industry – it’s posture. Our clients are real companies emailing into real companies. They can’t afford to burn domains, churn infrastructure, or show up in enterprise inboxes looking like a fly-by-night operation.

They want outbound that reflects the kind of company they are.

Typical profiles include founder-led sales teams that need to move fast without building an internal operation, lean growth teams that want execution speed without sacrificing system integrity, and companies scaling into enterprise or regulated markets where the target audience actively filters recently spun-up senders.

How long does it take to see results?

Honest answer: outbound is not instant, and anyone who tells you otherwise is cutting corners somewhere.

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. The specifics depend on your sending environment, the domains we are working with, and the target audience – but as a general guideline, most setups reach full operational run rate and results begin to normalize within about 30 days.

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 to, what messaging lands, what objections come up. That signal is how we dial things in.

Most of our clients commit to a multi-month engagement because they understand that iteration is how outbound actually works. The goal is not to get lucky with one campaign – it’s to build a system that produces consistent, compounding results over time. 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 does pricing look like for Outbound Operations?

Outbound Operations is typically $3,600 per month. That covers the full operational 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 our Managed Email Infrastructure.

When you break down what’s included, that $3,600 is covering the data you need, the backend infrastructure that keeps things out of spam, 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 less risk of things going sideways.

The system is also modular. If at some point you want to bring the campaign execution in-house but keep the infrastructure running, you can transition to Managed Email Infrastructure on its own. You’re not locked into the full service if your needs change.

Additional scope – like LinkedIn outbound coordination, multi-sender setups, or one-off campaign pushes – may be priced separately depending on the engagement. We are transparent about what’s included and what’s not.

Can we add more senders or increase volume over time?

Yes. The system is designed to scale with you without changing the operating model.

Adding senders, expanding into parallel audiences, or increasing throughput works within the same framework – same infrastructure, same operational approach, same quality controls. You don’t need to switch tools, rebuild campaigns, or renegotiate the engagement to grow.

Each additional sender goes through the same controlled warmup and ramp-up process to ensure the infrastructure remains healthy. Volume scales gradually and deliberately, not through hacks that introduce fragility.

If your outbound ambitions grow significantly – say, from a single-sender motion to a multi-sender, multi-audience operation – we accommodate that within the system. Operationally, very little changes from your perspective. The backend adjusts; the frontend experience stays the same.

What happens to our data and campaigns if we stop working together?

Your Apollo account, all campaign data, audiences, copy, and campaign structure are yours and immediately portable. You can disconnect and take all of that with you.

What isn’t portable is the sending infrastructure. The pre-warmed IPs, the IP reputation we’ve built, the backend sending layer – that’s our Managed Email Infrastructure, and it stays with us. Your domains are yours (they always were), but the IP backend that helps you scale is what you’re renting access to through the engagement.

The most common transition pattern we see is clients moving campaign execution in-house while continuing to use our Managed Email Infrastructure. That way, they keep access to the production-grade sending layer and run their own campaigns on top of it. It’s a clean handoff because the system is designed to support that separation.

If you’re leaving entirely, you walk away with your Apollo account, your data, your copy, and your domains. The infrastructure relationship ends, but nothing on the campaign side disappears.

We already have outbound running. Can you take over without starting from scratch?

Yes. We regularly onboard teams that have existing outbound operations – whether they’re running things in-house, working with another agency, or managing a patchwork of tools and freelancers.

The process starts with understanding what you have: what’s working, what infrastructure is in place, what data and campaigns exist, and where the current setup is fragile or underperforming. Some of what you’ve built will transfer cleanly. Other parts may need to be rebuilt – particularly if the underlying infrastructure relies on disposable domains, fragmented inboxes, or systems that won’t hold up under scale.

We prioritize continuity during the transition. The goal is to get you onto production-grade infrastructure and operational execution without a gap in activity or a loss of the momentum you’ve already built. Depending on the state of your current setup, that transition can happen quickly – often within the first few weeks.

If your current outbound is working well enough on the frontend but the backend is the problem (deliverability issues, infrastructure fragility, scaling bottlenecks), you may not need full Outbound Operations. Our Managed Email Infrastructure can slide underneath your existing workflows without disrupting what’s already running.
