AI SDR, outbound agency, in-house SDR, or an operated platform? Which one to pick when your buyers have a compliance team.
The short answer. An AI SDR gives you volume with nobody accountable for what goes out. An agency gives you activity that leaves when the retainer ends. An in-house SDR gives you a person who needs a system. An operated platform gives you the system, the strategy, and the people who run it, with your own team approving every send. For named accounts and regulated buyers, that last one is the right answer most of the time, and it is what Mabry does.
Below: the four options side by side, what each one owns and governs, the five questions a security review will ask each of them, and when each one is the wrong call.
Back to mabry.aiFour ways to run outbound, side by side
The feature comparison is where most of these guides stop. It is the least useful part. The rows that decide the choice are who approves each send, who holds your keys, and what you own when it ends.
| What matters | Operate (Mabry) | AI SDR | Outbound agency | In-house SDR |
|---|---|---|---|---|
| What you get | An operated platform in your systems, with the strategy and the people who run it | Software that sends at volume, per seat | A team running lists, sequences, and replies | A person, and whatever tools you give them |
| Who decides the accounts and the message | You, with our strategy team, working from signals in your market | The tool, from a list you upload | Mostly the agency | The SDR, or their manager |
| Who approves each send | Your person. Enforced in the platform, cannot be switched off | Usually nobody, by default | Their operator | The SDR, on their own |
| Where the research comes from | Sourced and dated. Nothing unsourced reaches a draft | Enrichment fields and a template | Their researchers, their standard | Whatever time they have |
| Time to first result | Weeks | Days | Weeks | A quarter to hire, a quarter to ramp |
| Who holds your credentials | You. We hold none | The vendor | The agency | You |
| What it does to your CRM | Creates records and notes. Cannot read a record | Reads and writes | Whatever access you gave them | Full access |
| What you own when it ends | Everything in your systems, plus the documentation | Seats | The meetings that were booked | The person, if they stay |
| Fits best when | Named accounts, regulated buyers, a motion that has to scale | A wide market and a simple offer | A short burst of activity | The system already exists |
Each one, honestly
1. Operate, with Mabry
The Mabry Signal Network running in your systems. It watches your market for the signals that mean an account is worth a conversation now, does the research with sources, and drafts what your team sends. A person on your team approves every send. We design the motion, run the platform, and answer for the number.
Autonomy. Nothing goes out without your approval, and no setting changes that. You also don't get the method: the drafts and the evidence are yours, the rubric and the prompts are ours. And no volume promises. Targets are set against your own baseline.
Your book is named accounts, your buyers have a security or compliance function, and you want the motion to scale without the exposure scaling with it. You want strategy, platform, and operation from one firm instead of three vendors.
You want a tool that sends on its own and you don't intend to review what goes out. That is cheaper. The exposure is yours.
2. An AI SDR
A product that writes and sends outbound at volume for a monthly fee per seat. Live in days. A dashboard of opens, replies, and meetings. For a simple offer into a wide market, it produces activity fast.
Anyone deciding which accounts, why now, or what the message should argue. The product is the motion. Most send without a person in the loop unless you configure otherwise, and most ask for read access to more of your CRM than the job needs. When a message lands wrong with a regulated buyer, the vendor's name is not on it. Yours is.
A wide, undifferentiated market, a simple offer, an ops person who understands deliverability, and nobody who will ever audit what was sent. Rare in B2B.
Named accounts, regulated buyers, or any book where a bad send costs more than a missed one. Then autonomy is the risk, not the feature.
3. An outbound agency
A team that runs it for you: lists built, sequences written, replies handled, meetings booked. Results in weeks. Someone to call when the number is off.
Anything that stays. The lists, the sequences, and the learning live in their tools. Your CRM gets the meetings, not the system that produced them. Approval is their operator's call, and the research is whatever their standard is that month.
You need activity for a short window and don't intend to keep the capability, and you're fine with the learning leaving when the retainer ends.
You want to own the motion in twelve months, or the work is complex enough that whoever does it needs to understand the business.
4. An in-house SDR, or a GTM engineer
Someone who learns your business and stays. An SDR runs the conversations. A GTM engineer builds the stack that feeds them. Over two years, with the system already in place, this is a strong seat to have.
The system, on day one. The person needs signals to work from, research to send, and a review step that doesn't depend on their judgment at 4:45 on a Friday. Good GTM engineers are scarce, take a quarter to hire and a quarter to ramp, and one person cannot also be the strategist and the governance function.
The motion is designed, the platform is running, and you want your own person in the seat. That is exactly the point where our clients add one, and the platform is what they ramp into.
You need the system before you can justify the hire, or you're hoping the hire will design the system. They'll spend the first year building tooling instead of pipeline.
What happens after a bad send
All four options look similar in a demo. They look nothing alike the morning after a message reaches a regulated buyer with a claim nobody can source, or a contact gets touched twice in the same week by two systems, or a record changes in your CRM and nobody can say why.
With an AI SDR, you find out from the buyer. With an agency, you ask them to check their tools. With an in-house SDR, you ask the person. With the platform, you open the log: who was contacted, when, why, which signal, who approved it. Every action is written at the moment it happens, and the log exports.
Any of these can produce activity in a pilot. The one worth choosing is the one that scales in production without scaling your exposure.
Five questions a security review will ask, whichever you pick
If you sell into financial services, insurance, healthcare, or anywhere with a compliance function, your security team or your customer's will ask these of whatever you choose. Ask them at the demo instead.
Mabry holds none. Approved work is handed to your own workspace to write on your own connections.
No. The approval step is enforced in the platform, not in a policy, and no setting turns it off.
Create records and notes. It cannot read a record that is already there. A daily ceiling and a contact suppression window are built in.
Yes. Every fact carries a source and a date. Every action is logged, and the log exports.
Everything the platform produced stays in your systems. Your data on our side is destroyed at term end and confirmed in writing.
Put the same five questions to an AI SDR vendor or an agency and write down the answers. That comparison decides more deals than the feature table.
Questions we get on this
Is an AI SDR compliant for financial services?
The tool isn't the compliance question. You are. Whatever you license, you remain the controller of the data it touches and the sender of every message. An AI SDR that sends on its own, with read access to your CRM, puts both of those on you with nothing in between. Compliance for outbound to regulated buyers comes down to a person approving each send, sourced claims, a suppression rule that actually holds, and a log you can produce a year later. Choose on those.
What's the difference between an AI SDR and an outbound agency?
An AI SDR is software that sends at volume with nobody accountable for the message. An agency is people who run the activity in their own tools and take the system with them when the retainer ends. One gives you seats, the other gives you meetings. Neither leaves you owning the motion.
Should we hire a GTM engineer instead?
Eventually, probably. Not first. A GTM engineer needs a designed motion and a running platform to work on, or they spend their first year building tooling. Our clients add that seat once the platform is running and the motion is proven, and the platform is what the hire ramps into.
Can an AI SDR replace our SDR team?
It can replace the volume. It cannot replace judgment, and it adds exposure your team didn't carry. For a simple offer into a wide market that trade can be fine. For named accounts and regulated buyers it usually isn't, which is why we built approval into the platform instead of around it.
What does operating with Mabry cost compared to an agency?
Engagements are fixed scope, quoted after the first working session, once we've seen your systems and the motion that matters most. What we'll say here: there is no per-seat fee and no retainer that ends with you owning nothing. Everything the platform produces is in your systems from the first week.
Bring us the motion that matters most.
In one working session we'll show you the motion running on the platform, before you spend a dollar. If it isn't revenue, say so. The platform doesn't care, and we'll tell you straight whether we've done it before.
First session is a working session, not a pitch · Your data never leaves your stack · If we're not the right fit, we'll tell you on the first call.
