Let's break down how Mailreef works in simple steps so you can see if it’s the right choice for scaling your cold email outreach.
Trust me, it’s simpler than it sounds, and I’ll guide you through the process like a friend explaining over a coffee chat.
The first step is to set up an account on Mailreef's platform. This involves signing up and accessing their dashboard, where you can manage everything. The dashboard is user-friendly and straightforward, allowing you to navigate the various options without much hassle.
Once you're set up, you can purchase domains directly from the Mailreef dashboard with a single click. This is particularly useful if you want to create multiple domains for cold email campaigns.
After purchasing a domain, Mailreef allows you to create mailboxes quickly, and it automatically configures essential DNS records like SPF, DKIM, and DMARC.
This setup ensures better deliverability and reduces the chances of your emails landing in spam folders.
Mailreef promotes itself as offering "unlimited" mailboxes, which means you can create numerous mailboxes without additional costs per mailbox.
However, it's important to note that while Mailreef advertises unlimited sending, there are caps. For example, you can send up to 100,000 emails a month.
If you plan to send more, there’s an additional cost involved. So, while the term "unlimited" may sound appealing, it's essential to understand the practical limitations.
One of the standout features of Mailreef is the use of dedicated IP addresses for sending emails.
This is different from shared infrastructure services like Gmail or Outlook, where your email deliverability could be affected by other users.
With a dedicated IP, you have more control over your email reputation. However, the downside is that if you don’t manage your emails well, any negative impact is solely on you.
Mailreef also integrates with APIs and Zapier, allowing for automation of domain and mailbox creation.
This is particularly beneficial for users who want to scale up without getting bogged down in manual processes.
You can set up triggers and automate tasks, making it easier to manage a growing number of mailboxes and domains.
To help maintain a good sending reputation, Mailreef provides spam screening features. This helps filter out spam accounts and ensures that your email campaigns have a better chance of reaching the inbox.
This can be a helpful feature, but like all deliverability tools, its effectiveness depends on how well it's used in practice.

Lastly, Mailreef provides tools for monitoring your email campaigns, such as tracking open rates and bounce rates. These metrics help you gauge how well your campaigns are performing and adjust your strategies accordingly.
This kind of monitoring is standard among email service providers, but it's still a valuable feature for optimizing your cold email outreach.

When considering a tool like Mailreef for scaling your cold email campaigns, it's essential to weigh the advantages and drawbacks.
Here’s a breakdown of the 5 pros and 5 cons of using Mailreef:
Mailreef allows you to purchase domains and create mailboxes with just one click. This feature significantly reduces the time and technical effort required to set up email infrastructure, which is a huge advantage for businesses looking to scale quickly.
With Mailreef, you get dedicated IP addresses for your cold email campaigns. This ensures that your email reputation is in your control, unlike shared IP services where other users' actions can affect your deliverability.
Mailreef supports integration with APIs and Zapier, making it possible to automate the creation of new domains and mailboxes. This level of automation is ideal for users who want to streamline their workflow and reduce manual tasks.
The platform offers unlimited mailbox creation, allowing you to scale your cold email efforts without additional costs per mailbox. This can be particularly beneficial for businesses running large-scale campaigns that require multiple email accounts.
Mailreef includes a spam screening process that helps maintain high deliverability rates. This feature filters out potential spam accounts, helping you protect your sending reputation and ensuring your emails reach the intended inboxes.
Like what you're reading?
Infraforge does more, for less.
Same dedicated IPs and unlimited mailboxes — at just $3 to $4 per mailbox/month.
Transparent pricing, no per-email charges, fully scalable.
Or pay the markup. Your call.
While Mailreef markets its services as "unlimited," there are caps on certain features. For example, you can send up to 100,000 emails per month, and if you exceed this limit, additional costs apply. This can be misleading for users who expect true unlimited access.
Mailreef’s pricing can be confusing, especially with its combination of a flat monthly fee and a per-email cost. This may not be ideal for businesses looking for simple, transparent pricing. The additional fees for exceeding limits can add up quickly, making it less predictable.
Due to its pricing model, Mailreef can become expensive if you are running very large-scale campaigns. For instance, after a certain point, you might need to spin up additional servers, which means paying the monthly fee again. This could lead to higher costs than initially anticipated.
Having a dedicated IP address can be a double-edged sword. While it provides control, it also means that if you don’t manage your campaigns properly, you risk damaging your IP’s reputation. This could lead to lower deliverability rates and impact your campaign's effectiveness.
Mailreef is specifically designed for cold email campaigns, meaning it might not be as versatile for other types of cold email outreach. If you need a more comprehensive outreasch solution that handles both cold and warm emailing or other marketing tasks, Mailreef might not be the best fit.
Mailreef offers several compelling features for businesses focused on cold emailing, such as automated setup, dedicated IPs, and spam screening. However, it also comes with certain limitations, including complex pricing and hidden caps that could affect its cost-effectiveness. Weighing these pros and cons can help you decide if Mailreef aligns with your specific email outreach needs and budget.
Hidden caps adding up?
Infraforge skips the gotchas.
Flat per-mailbox pricing, no surprise overages, no per-email fees.
Scale outbound without watching the meter.
Or keep auditing line items every month.
Mailreef positions itself as an “unlimited” solution for scaling cold email infrastructure, but it's important to look closely at the details to understand what you're actually getting.

While the Mailreef pricing structure seems straightforward at first, there are some limitations and additional costs that you should be aware of.
Mailreef starts at $249 per month for unlimited mailbox creation. This flat fee covers the basic use of the platform, including setting up multiple mailboxes and domains.
However, this “unlimited” offering comes with certain restrictions that aren't immediately apparent.
On top of the monthly fee, you are charged $0.001 per email sent. This might seem negligible, but if you’re sending a large volume of emails, these costs can quickly add up.
For example, sending 100,000 emails would cost an additional $100.
Each domain purchased through Mailreef costs $19. If you're running multiple campaigns and need several domains to maintain deliverability, these costs can also stack up.
Although Mailreef promotes “unlimited” mailboxes and sending limits, there are actual caps. For instance:
So, while Mailreef advertises “unlimited” features, they are only unlimited within these boundaries.
Let’s break down a practical example to make things clearer. Imagine you run a cold email campaign where you plan to use:
Here's how the cost would look:
Total Monthly Cost: $249 (base fee) + $80 (per email cost) + $190 (domain cost) = $519
Now, consider that you want to increase your scale. If you send 120,000 emails and need 60 mailboxes (exceeding the 50-domain limit), you’d need another server. That’s another $249 added to your total, plus the extra cost of 20,000 more emails:
New Total Monthly Cost: $519 (initial total) + $249 (extra server) + $20 (extra emails) = $788
Mailreef offers robust tools for scaling cold email campaigns, but the pricing isn't as unlimited as it first appears. Costs can increase substantially depending on the number of emails sent and domains needed.
If you're considering Mailreef, it's crucial to understand these hidden costs and limitations to ensure it fits within your budget and campaign needs.

Infraforge starts at $3/mailbox.

Let's get straight to the point—is Mailreef worth it? If you’re like me, you want to make sure every dollar spent adds real value, especially when scaling your cold email campaigns.
If you’re running a smaller campaign and don’t mind the extra costs, Mailreef could still work for you. It does simplify many tasks and gives you control over deliverability.
Infraforge offers similar features—dedicated IPs, easy setup—but with a clear and straightforward pricing model. Starting at $4 per mailbox, no hidden fees, and no confusing limits. If you want something simple and cost-effective, Infraforge might be the smarter choice.

Bottom Line: Mailreef is powerful but potentially pricey. If you value simplicity and transparency, give Infraforge a look. It could save you money and make managing your cold email campaigns a breeze. Let me show you how.
