ColdOps

Comparison

ColdOps vs MailReach

MailReach warms your mailboxes and scores them on the warmup mail it sent itself. ColdOps reads the campaigns you actually send and writes the client's weekly update. Both are real tools; here is the honest line between them.

Start for free

One grades its own mail. The other grades yours.

This is the whole difference, and it is easy to miss because both produce a score. Look at which traffic the score was calculated from.

MailReach
Connect the mailbox over SMTP
It sends warmup mail to its own inbox network
A reputation score, from that traffic

Real, useful, and measured on mail that was never sent to a prospect.

ColdOps
Connect the client workspace once
Reads the campaigns you actually sent
Reply rate, bounces and volume against that campaign's own baseline

Measured on the mail that decides whether the client renews.

The short version

MailReach warms the mailboxes.
ColdOps watches what you send from them.

Choose MailReach if

  • You need warmup that actually sends — a 30,000+ inbox network, plus spam-placement tests and AI content fixing in the same plan. ColdOps does none of that.
  • You want a reputation score per mailbox, broken down by domain, tag and provider, with deliverability specialists to call.

Choose ColdOps if

Most agencies
  • You run an agency and need every client's live campaigns, mailboxes and domains watched in one place — across Instantly, Smartlead, EmailBison and Apollo, graded worst-first.
  • You want the alert to fire on the client's real reply rate sliding, not on a score calculated from warmup traffic — and the Friday client update written for you.

And yes — you can run both, and at scale most agencies should: MailReach warms the mailboxes and grades their reputation, ColdOps watches the campaigns running through them and writes the client reports. They meet at your mailboxes, not in each other's way.

The structural difference

MailReach tells you a mailbox's score moved. ColdOps tells you which client's campaign is dying, why, and what to say on Friday.
A score built from warmup traffic cannot see a reply rate. That is not a flaw in MailReach — it is what connecting at the mailbox instead of the campaign means.

Side by side

The highlighted rows are the ones that actually decide it, and two of them go to MailReach. We would rather you bought the right tool than the wrong one twice.

Questions, answered.

Is ColdOps a MailReach alternative?+

For watching what your clients' campaigns are actually doing and writing the weekly client update, yes — that is ColdOps' job and MailReach does not do it. As a warmup tool, no. MailReach runs a warmup network of its own and ColdOps sends no mail at all. A lot of agencies should run both: warm with MailReach, watch with ColdOps.

What is the real difference between them?+

What each one measures. MailReach connects to a mailbox over SMTP and grades it on the warmup mail it sent to its own network — a reputation score, per mailbox, moving over 48 hours. ColdOps connects to the sending platform and reads the campaigns you actually send: reply rate, bounce rate and volume against that campaign's own baseline. MailReach can tell you a mailbox's score dropped. It cannot tell you which client's campaign is dying, because it never sees the campaign.

Does ColdOps warm up mailboxes?+

No, and it is a deliberate no. Warmup means sending mail from your accounts, and the moment a monitoring tool also sends, its own traffic is in the numbers it grades you on. ColdOps only reads. If you want warmup, MailReach's network is a real one — 30,000+ inboxes across Google Workspace and Office 365, up to 100 warming emails per mailbox per day.

What does MailReach cost?+

Per mailbox, per month, in euros, on a volume ladder: €25 for 1–5 mailboxes, €19.50 for 6–20, €18 for 21–50 and €16 for 51–100. Annual billing takes 20% off each band. Above 100 mailboxes their pricing page stops and asks you to contact them, so there is no published agency rate. There is no free tier and no free trial. Figures read from mailreach.co/pricing on 23 August 2026.

So which is cheaper?+

They are not the same purchase, so the honest answer is that it depends what you need done. What can be said plainly is the shape: MailReach's bill grows with every mailbox you add, and ColdOps' does not move until your book crosses a band. At 100 mailboxes — the largest size MailReach publishes — their best published rate is €16 each. ColdOps Agency watches up to 1,500 mailboxes for $99 a month. But MailReach's price includes warmup that really sends and spam tests that really run. ColdOps does neither.

Can I use both?+

Yes, and it is the setup we would suggest for most agencies at scale. MailReach warms the mailboxes and tells you their reputation. ColdOps watches every client workspace across Instantly, Smartlead, EmailBison and Apollo, grades each client and writes the client-ready weekly update. They touch different halves of the same problem.

Keep warming your mailboxes. Add the layer that watches the campaigns.
