Comparison
ColdOps vs Peeker: different jobs, honestly compared.
Peeker sells inboxes that monitor and replace themselves. ColdOps is independent monitoring and client reporting for agencies — and sells no inboxes at all.
When a client's domain burns, who profits?
Same event, two business models. Follow the money down each lane.
The vendor grading your inboxes also profits when they fail.
We only win if your clients' campaigns stay healthy.
The short version
Choose Peeker if…
- You want to buy Google or Microsoft inboxes with warmup, burn detection, and automatic replacement handled for you.
- Infrastructure babysitting is your bottleneck and you're happy to pay per inbox for a vendor that swaps burned ones automatically.
Choose ColdOps if…
Most agencies are here- You run an agency and need every client's campaigns, mailboxes, and domains watched in one place — on whatever infrastructure you already use.
- Your real risk is a client finding a problem before you do — so you want health scores, one-alert-per-issue, and the Friday client update written for you.
And yes — you can run both: Peeker provisions and swaps your inboxes, ColdOps independently monitors every client workspace and writes the reports. They meet at your sending platform, not in each other's way.
The structural difference
Peeker's free monitoring is an on-ramp to inbox sales — so the vendor grading your infrastructure also profits when it fails. ColdOps sells nothing downstream of an alert, so the only thing we're protecting is your client.

Questions, answered.
Is ColdOps a Peeker alternative?+
For deliverability monitoring and agency reporting, yes. For inbox infrastructure, no — Peeker sells Google and Microsoft inboxes with automatic replacement; ColdOps doesn't sell inboxes at all. If you want to buy self-replacing inboxes, use Peeker. If you want independent monitoring of every client workspace plus client-ready weekly reports, use ColdOps.
Does ColdOps replace burned inboxes automatically?+
No. ColdOps detects the failure, alerts you once by email or Slack, explains the likely root cause with AI, and can auto-pause the affected campaign or mailboxes (reversibly, with an audit trail). Replacement stays your call — because we don't sell the replacements, we have no reason to push them.
Can I monitor Peeker inboxes with ColdOps?+
Yes. ColdOps monitors whatever your sending platform sees. If your Peeker inboxes send through Instantly, Smartlead, or EmailBison, connect the workspace API key and ColdOps tracks those campaigns, mailboxes, and domains like any other — alongside every other client, with health scores and weekly reports on top.
Why is Peeker's monitoring free when ColdOps charges for it?+
Different business models. Peeker's revenue is inbox sales, so monitoring is a free on-ramp — each detected burn can become a replacement order. ColdOps sells the monitoring and reporting itself, flat-rate, with no infrastructure to upsell. You're paying for an independent referee instead of getting a free one from a team that's also playing.
What does each one cost for a typical agency?+
They price different things. Peeker charges per inbox ($2.80–$3.50/inbox/mo, Google or Microsoft, domains extra on Azure) — for 400 inboxes that's roughly $1,200/mo, including the infrastructure itself. ColdOps is a flat $49–$249/mo for monitoring and reporting across your whole book, whatever inboxes you already run and keep paying for elsewhere.
