MailScale is a popular option for creating inboxes for cold email campaigns. But as outbound programs grow, many teams start looking for alternatives that offer real Google Workspace or Microsoft 365 mailboxes, better deliverability, or more control over their email infrastructure.
The reason is simple. Your mailbox setup plays a major role in whether emails land in the inbox, spam folder, or get blocked altogether. Choosing the wrong provider can make it harder to scale outreach, manage multiple domains, and maintain a healthy sender reputation.
That's why agencies, SDR teams, SaaS founders, and GTM teams often compare different mailbox providers before committing to a long-term setup.
In this guide, I'll compare the best MailScale alternatives for real workspace mailboxes, including Primeforge, InfraForge, Mailreef, Mailpool, and Inboxkit. We'll look at their features, pros, cons, and ideal use cases so you can find the right provider for your outbound infrastructure.

Primeforge is one of the strongest MailScale alternatives for businesses that want real Google Workspace and Microsoft 365 mailboxes for cold outreach.

2. InfraForge
Best For: Agencies, outbound teams, and businesses that want more control over their email infrastructure than MailScale provides.
This image shows the Infraforge homepage
If your main goal is getting more control over your email infrastructure, InfraForge is one of the strongest MailScale alternatives to consider. While MailScale focuses on making inbox creation fast and simple, InfraForge takes a different approach.
It gives you private email infrastructure with dedicated IPs, multi-IP provisioning, and advanced infrastructure controls that are built specifically for cold outreach.
What I like is that InfraForge still removes much of the technical work. It automatically handles SPF, DKIM, DMARC, DNS setup, and mailbox provisioning, so you can get started quickly without manually configuring everything yourself.
For agencies, outbound teams, and businesses sending large volumes of cold emails, the extra control can be valuable as campaigns grow.
Key Features of Infraforge
Dedicated IP infrastructure.
Automated SPF, DKIM, and DMARC setup.
Automated DNS configuration.
Domains and mailboxes ready in around 5 minutes.

3. Mailreef
Best For: Agencies and outbound teams that want dedicated servers, dedicated IPs, and more control over their cold email infrastructure.
This image shows the Mailreef homepage
Mailreef is a cold email infrastructure platform built around dedicated servers and dedicated IPs. The biggest difference I noticed is that Mailreef focuses heavily on dedicated infrastructure. I
nstead of using shared resources, every customer gets a dedicated mail server and dedicated IP address. The platform is built specifically for cold email teams that send large volumes of outreach and want more control over their sending environment.
I also like that Mailreef keeps setup simple. You can create domains and mailboxes quickly, SPF, DKIM, and DMARC records are configured automatically, and the platform integrates with popular sending tools like Smartlead and Instantly.
That said, Mailreef is more infrastructure-focused than MailScale. If your goal is simply creating inboxes as quickly and cheaply as possible, MailScale may feel easier. But if you want dedicated servers and dedicated IPs, Mailreef offers something different.
Key Features of Mailreef
Dedicated mail server.
Dedicated IP address.
Automatic SPF, DKIM, and DMARC setup.
One-click domain purchases.
One-click mailbox creation.
Unlimited inboxes.
API access.
Server and mailbox monitoring.

This image shows the Mailpool homepage
Mailpool is one of the most flexible MailScale alternatives I came across. Instead of locking you into a single type of infrastructure, Mailpool lets you create inboxes on Google Workspace, Microsoft 365, Mailpool's own infrastructure, or dedicated servers from the same platform.
What stood out to me is how much of the setup is automated. You can buy domains, create inboxes, configure SPF, DKIM, and DMARC records, set up forwarding, and connect your outreach tools without handling the technical work yourself.
This image shows the Purchase domains on Mailpooli
I also like that Mailpool is built for teams that need to scale. Whether you're managing a few inboxes or hundreds of them, everything can be managed from a single dashboard. Compared to MailScale, Mailpool gives you more flexibility when it comes to mailbox providers and infrastructure options. That makes it a good fit for teams that want more choice as their outbound setup grows.
Key Features of Mailpool
Dedicated infrastructure options.
Automated SPF, DKIM, and DMARC setup.
Bulk domain purchases.
Unlimited inbox rotation .
Domain and IP blacklist monitoring.
Deliverability audits.
One-click exports to outreach tools.

This image shows the Inboxkit homepage
InboxKit is a cold email infrastructure platform built for teams that want Google Workspace, Microsoft 365, and Azure mailboxes from one dashboard. What I like about InboxKit is that it is not just a mailbox-buying tool.
It also helps with DNS setup, warmup, deliverability monitoring, inbox placement tests, analytics, and sequencer exports. So instead of buying inboxes in one place and checking deliverability somewhere else, you can manage most of the infrastructure workflow inside InboxKit.
Compared to MailScale, InboxKit feels more feature-heavy. MailScale is simpler if you only want fast inbox creation. But InboxKit is stronger if you want more visibility, monitoring, integrations, and control over your cold email infrastructure.
Key Features of InboxKit
Google Workspace mailboxes.
Microsoft 365 mailboxes.
Azure mailboxes.
Automated SPF, DKIM, and DMARC setup.
Built-in warmup add-on.
InfraGuard monitoring for blacklist, DNS, bounce, and inbox placement issues.
Inbox placement testing.
Mailbox analytics dashboard.
24+ sequencer integrations.
Full API access with webhooks.
Unlimited team members and workspaces.
