Here's the trap. You run a full-stack tool for eight months, it does not work, and you cancel. Then you discover that the domains were theirs, the mailboxes were theirs, and the eight months of sending reputation you built went with them. You are not back where you started. You are six weeks behind it.
Outbound builds exactly one durable asset: warmed sending domains with a reputation attached. The copy is reproducible in a week. The list is buyable in an hour. Reputation is the only part that takes calendar time, and calendar time cannot be bought back.
So the real question in the AI SDR category is not which product performs better. It is which model leaves you holding the asset when the arrangement ends, and on every published estimate for this category, it ending is the likely outcome rather than the unlucky one.
What is the actual difference between the two models?
Managed means the vendor runs the whole motion on their infrastructure. They register the domains, they provision and warm the mailboxes, they send. You get results and a dashboard. 11x and Artisan sit here.
Owned means you assemble it: a research layer, a sequencer, and your own domains and mailboxes. Clay plus Instantly or Smartlead is the common shape. You get more work and everything stays in your name.
Most comparisons stop at cost, which is the least interesting axis because the answer is obvious and does not settle anything.
What does each one cost?
| Line | Rate | Monthly |
|---|---|---|
| Sequencer, Smartlead Base | $39/mo for 6,000 sends | $39.00 |
| 10 mailboxes, Mailforge | $3 each, billed yearly | $30.00 |
| 4 domains, Mailforge | $14 a year each | $4.67 |
| Sending infrastructure subtotal | $73.67 | |
| Clay, research layer | entry tier | $185.00 |
| Owned total | $258.67 |
That is $3,104 a year, excluding verification, warmup and optional SSL, computed from rates published in August 2026. Against it, the median managed contract in our records is $45,000 a year, with observed values running from $9,000 to $65,640.
The gap is real and it is not the argument. The owned stack needs a person to run it and the managed one is sold on not needing one, which we went through task by task in what an AI SDR actually does all day. Cost tells you what you are paying. It does not tell you what you are left with.
What do you keep when it ends?
| Managed | Owned | |
|---|---|---|
| The contact list | Usually exportable | Yours |
| The copy that worked | Yours | Yours |
| The warmed domains | The vendor's | Yours |
| The sending reputation | Gone | Intact |
| Time to restart sending | Weeks of re-warming | None |
The first two rows are why this rarely comes up in a sales conversation. You do get your data back, in the ordinary case, and the messages are yours. It reads like a clean exit right up until you try to send anything.
We made the same point about agencies from the other direction: ask who owns the domains and settle it before the first send. If the agency registered them, a departing client cannot take the reputation. If the vendor registered them, neither can the agency. Either way it is weeks of warmup that nobody gets back, and it is the cheapest clause to agree at signup.
Why does this matter more than it sounds?
Because leaving is the normal outcome in this category, not the unlucky one. The cancellation estimates run from 11x's own implied 21 percent, derived from the 79 percent retention it published, up to the 70 to 80 percent a former employee described to TechCrunch. A widely repeated category range of 50 to 70 percent sits between them, and we could not reach a primary source for it, so treat it as circulating rather than measured.
Under any of those numbers, a large share of buyers will be exiting within a year or two. Exit terms are not a corner case to be handled if things go wrong. They are the modal experience of buying in this category.
That puts domain ownership in the same class as the break clause, which we found is worth more than a 20 percent discount at any cancellation rate above 30 percent. Nobody negotiates either one, and both cost nothing to ask about at signup.
So which should you choose?
- If you have never proved the motion by hand, own the infrastructure. At $73.67 a month for the sending layer you can afford to be wrong, and if it works you keep the warmed domains and can then buy anything you like on top of them.
- If you are buying managed, ask three questions in writing. Who registers the domains. Whether they can be transferred to you on exit and at what cost. And what happens to the mailbox warmup history if they are.
- Treat the answers as a price adjustment, not a detail. If the domains do not transfer, the real cost of the contract includes rebuilding six weeks of reputation afterwards, and that belongs in the comparison alongside the annual figure.
- Register the domains yourself even under a managed arrangement, if they will allow it. It is about $14 a year each. It is the cheapest insurance in the whole category and the only version of this problem that has a simple fix.
- Whatever you choose, budget the identities separately. Mailbox and domain costs scale linearly with volume and are rarely on a pricing page, which we itemised in what cold email actually costs.
The difference between the two models does not show up in the first month or in the price comparison. It shows up on the day you leave, which for most buyers in this category arrives sooner than the contract does.
