What is Mailreef?

It gives each customer a fully dedicated mail server and dedicated IP address, so no other sender can affect their reputation.

The platform is made for teams that need to send large amounts of cold email without using shared servers or rotating IPs.

Mailreef allows 1-click domain and mailbox creation and automatically sets up SPF, DKIM, and DMARC for every domain.

All mailboxes support standard SMTP and IMAP, so they can connect to tools like Smartlead and Instantly.

Mailreef also provides live deliverability support to help users monitor, fix, and optimize email delivery while they scale.

Here are the top pros and cons of Mailreef:

Is Mailreef the Right Fit for You?

If your goal is to scale cold email sending with your own dedicated server and full control over deliverability, Mailreef is a strong option.

But if you want an all-in-one outreach app with sequencing, lead sourcing, and campaign management built in, you will still need to connect Mailreef to a separate sending tool.

I. Mailreef is right for you if:

• You send high volumes of cold email and need stable, private infrastructure.
  
  
• You want a dedicated mail server and dedicated IP instead of shared inboxes.
  
  
• You need fast domain and mailbox creation using API or one-click setup.
  
  
• You are ready to warm up inboxes before starting campaigns.
  
  
• You can follow safe limits like around 20 cold emails per mailbox per day.
  
  
• You use tools like Smartlead or Instantly and need SMTP/IMAP access.
  
  
• You want automatic SPF, DKIM, and DMARC setup for every domain.
  

II. Mailreef might not be ideal if:

• You only send low volumes and need just 1–2 simple inboxes.
  
  
• You want built-in sequencing, CRM, or lead management.
  
  
• You do not want to spend time on warmup and gradual ramp-up.
  
  
• You prefer shared providers like Google or Microsoft with simple UI.
  
  
• You do not want to manage multiple domains for safe scaling.
  

Best Mailreef Alternative for Google & Microsoft Cold Email Mailboxes → Primeforge

Mailreef focuses on private SMTP servers and full server control. 

But many teams prefer sending from real Google Workspace or Microsoft 365 inboxes because recipients trust those providers more.

Primeforge is a cold email infrastructure platform that provides fully compliant, pre-warmed Google Workspace and Microsoft 365 mailboxes built specifically for cold outreach and deliverability.

Here’s a quick comparison between Mailreef and Primeforge:

In short, choose Mailreef when you want full private server infrastructure. 

Choose Primeforge when you want real Google or Microsoft inboxes that are fast to launch, pre-warmed, and built to land in the primary inbox.

Is Mailreef Worth It?

Mailreef is a good option if you need full control over cold email infrastructure. 

It gives you a dedicated server, your own IP, and automated setup for domains, DNS, and mailboxes. This makes it useful for teams sending large volumes of cold email.

Mailreef works well for agencies and teams that want private SMTP infrastructure and are comfortable managing warmup, daily sending limits, and careful ramp-up.

However, if your goal is stronger inbox placement using native Google Workspace or Microsoft 365 mailboxes that recipients already trust, Primeforge is the better choice.

Primeforge creates real Google and Microsoft mailboxes that are pre-warmed, ready to send fast, and optimized for cold outreach.

It also supports profile pictures, GIFs, and works with any cold email software, helping emails look more real and land in the inbox more often.

If deliverability matters most to you, Primeforge is the better option to start with.
