Most companies don’t need to evaluate all three services at once. They come to us with a specific situation — and the right service depends on that situation.

Senders offers three services: Outbound Operations, Managed Email Infrastructure, and Deliverability Consulting. They work independently or together. You can start with one and add others as your needs change.

Here’s how to decide which one to start with.

You Want Pipeline but Don't Have the Team to Run Outbound

Start with Outbound Operations.

This is the right fit if:

  • You need outbound producing results, but don’t want to build the internal function.
  • You’re a founder-led or lean growth team that needs immediate pipeline.
  • You’re hiring SDRs but need pipeline now.

What Outbound Operations includes:

  • Full execution: audience building, data sourcing, campaign construction, copy, testing, iteration, and scaling.
  • Minimal team involvement: your role is strategic direction and follow-up (<1 hour/week).
  • Managed Email Infrastructure is included underneath: aged domains, pre-warmed IPs, controlled DNS, continuous monitoring — the full sending layer.
  • Everything we build is yours: audiences, campaigns, copy, data — real-time access for your team.

Most companies start here when they want outbound as a channel but lack internal infrastructure to support it.

Your Team Can Run Campaigns, but the Sending Layer Is the Problem

Start with Managed Email Infrastructure.

This is the right fit if:

  • You have an internal team or agency running campaigns, but deliverability is degrading.
  • Email volume can’t scale due to IP throttling, domain reputation loss, or unexplained bounce rates.

What changes with Managed Email Infrastructure:

  • Keeps your existing tools: Apollo, Outreach, Salesloft, HubSpot, etc.
  • Professionally managed sending layer: aged domains, pre-warmed IPs, tight authentication, continuous monitoring, and active intervention.
  • Clean separation between execution and infrastructure, supporting future transitions from Outbound Operations to internal execution.

Common path: start with Outbound Operations, hire your team, then keep Managed Infrastructure running underneath.

Something Is Broken and You Need Clarity Before Committing

Start with Deliverability Consulting.

This is the right fit if:

  • Deliverability has dropped and no one can explain why.
  • You inherited a sending setup that seems unhealthy.
  • You want to verify infrastructure before scaling.
  • A migration went sideways, and recovery has stalled.
  • You need an independent audit of email authentication posture.

What happens in the Diagnostic & Quick-Fix session:

  • Reviews authentication, domain/IP reputation, sending behavior, and inbox placement signals.
  • Identifies many issues immediately; scopes follow-on engagement if needed.
  • Your team retains full ownership and implements fixes. No commitment to ongoing services unless desired.

Good starting point for first-time evaluation, ensuring clarity before making a bigger decision.

Evaluating From an IT, Security, or Operations Perspective

  • Ongoing governance needs → Managed Email Infrastructure: managed, documented, defensible, with line-by-line DNS review, tight authentication monitoring, and intervention protocols.
  • One-time assessment needs → Deliverability Consulting: audit DNS, verify email authentication, understand exposures.

Decision boils down to:

  • Configuration problem: fix once, maintain internally → Deliverability Consulting.
  • Operational problem: requires continuous monitoring → Managed Email Infrastructure.

Many teams start with consulting, discover systemic issues, and then move to Managed Infrastructure.

Not Sure Where the Constraint Is?

Most companies aren’t sure.

  • A conversation with our team helps determine what fits.
  • Sometimes it’s one service, sometimes a combination.
  • Sometimes no service is needed immediately — and we’ll tell you.

Design principle:

  • Each service delivers value independently.
  • Transition between services is clean: no lock-in, no forced bundling, no dependency traps.

Common Progressions We See

  • Outbound Operations → Managed Infrastructure: Start with execution support, hire SDRs, transition campaigns in-house, keep Managed Infrastructure.
  • Deliverability Consulting → Managed Infrastructure: Start with diagnostic, discover systemic problems, move to managed infrastructure.
  • Managed Infrastructure → add Outbound Operations: Stabilize infrastructure first, then add execution support for faster results.
  • Deliverability Consulting → done: Fix problems identified by diagnostic; no ongoing services needed.

None of these paths are mandatory — they’re just common patterns.

The Short Version

  • Need pipeline without building internal operations? → Outbound Operations
  • Have a team running campaigns but infrastructure is the bottleneck? → Managed Email Infrastructure
  • Something is broken and you need clarity before committing? → Deliverability Consulting
  • Need ongoing governance and defensibility? → Managed Email Infrastructure
  • Need a one-time assessment or audit? → Deliverability Consulting
  • Not sure? → Talk to our team

Every engagement starts with a conversation — not a pitch deck or demo. We figure out what fits, and if nothing fits, we tell you.

We’d love to learn more about your business, email deliverability and outreach goals, and see if we might be able to help.

Whether you have questions about what we do, how Protocol works, or you’d just like to pick our brains on some of our best practices, we’d be happy to chat.

Senders Case Studies

See All Case Studies

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
