Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
1.4
GPA, above 1 of the 81 other cold outreach tools we grade
Mailreef provides a dedicated mail server with its own IP address and a pool of mailboxes that cold emailers connect to a sender such as Smartlead or Instantly. Domains and mailboxes can be created in one click, with SPF, DKIM and DMARC set up automatically. It is aimed at senders moving more than 20,000 cold emails a month.
To get you started, here are 8 things to know about Mailreef, taken from its own pages and our grades.
You book a demo, then connect mailboxes to a separate sender.
- 1
Best for a dedicated cold email server for high volume
It supplies mailboxes only, so you still need Smartlead, Instantly or another sender.
- 2
Paid plans start at $240 a month
As its pricing page puts it: $240 per month on a 12-month commitment, plus $0.001 per send.
- 3
It runs on Web
Web.
- 4
Dedicated server and IP
Each plan includes a dedicated mail server and IP address, with 150 or more mailboxes per server and no shared resources.
- 5
One-click domains and mailboxes
Domains can be bought and mailboxes created in one click, or you can bring your own domain. SPF, DKIM and DMARC records are created automatically.
- 6
Pre-warmed setup
The comparison table lists a pre-warmed server, domains and mailboxes so campaigns can start on the first day.
- 7
A 1.4 GPA, above 1 of 81
That is against the other cold outreach tools we grade, on value, the free plan, features, ease of use and platforms.
- 8
Keep it
To replace Mailreef you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for a dedicated cold email server for high volume
Mailreef gives you a dedicated mail server and IP with 150 or more mailboxes, for people sending over 20,000 cold emails a month. At $240 a month on a 12-month commitment, plus $0.001 a send, it is among the dearest in the category and is only bought through a demo. It supplies mailboxes only, so you still need Smartlead, Instantly or another sender.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | $240 a month on a 12-month commitment ($249 month to month), plus $1 per 1,000 emails. The dearest tenth of cold-outreach tools starts at $120, though you do get a whole dedicated server. |
| Free plan and trial | F | No free plan and no trial; both plans are booked through a demo. |
| Features | D | A dedicated server, mailboxes, monitoring and an API, but no sending tool, leads or sequences. It needs another product to be useful. |
| Ease of use | C | No store rating on record. You book a demo, then connect mailboxes to a separate sender. |
| Platforms and integrations | B | Web, with an API and Smartlead and Instantly connections. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Mailreef is for
- Fits if you send more than 20,000 cold emails a month and want your own server
- Works for agencies that already run Smartlead or Instantly
Who it is not for
- Not for you if you send a few hundred emails a month, as the plan starts at $240
- Pricey if you can't commit for 12 months: month to month is $249
- Skip it if you want to try before paying, since both plans go through a demo
- Watch out: $0.001 a send is added to the monthly price
- Too light on its own, because campaigns are sent from a separate tool
Good to know
Good for
- Agencies sending large cold email volumes
- Senders who want their own mail server and IP
- Teams already using Smartlead or Instantly for sending
Worth knowing
- A per-send fee of $0.001 is added to the monthly price, which is $1 for every 1,000 emails.
- The cheaper Agency price needs a 12-month commitment; month-to-month costs $249.
- Both priced plans are booked through a demo, and no free plan or trial is listed.
- It supplies mailboxes only: campaigns are sent from a separate tool.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Mailreef you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 77 of the 81 other cold outreach tools grade higher. It costs $2,880 a year.
What you could not
- A network of real inboxes that open and answer your emails.
- Reading the reports inbox providers send about your domain.
- It plugs into other products, Smartlead and Instantly among them, and has an API.
What this rests on. Mailreef’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
