Create Cold Email Mailboxes Right Inside PenguinMails
No Gmail. No SMTP.
Just click “Create Mailbox” and start sending, because cold email needs control, and it starts with your inbox.
Don’t rent one. Own it.
You’re Not Connecting Mailboxes.
You’re Creating Them.
Most tools ask you to bring your inbox.
We let you create one inside PenguinMails.
No more SMTP errors, Gmail limits, tracking issues or setup headaches. Just connect your domain and start fresh.
You don’t need a third-party inbox.
You create real email accounts (mailboxes/inboxes) from scratch, on your own domain.
And they work like any regular inbox. You can send, receive, reply, and check everything from one place.
It’s not a mailbox connection. It’s mailbox creation.
Why It's Better Than Connecting Gmail/SMTPs
Built-In Mailboxes Beat Connected Accounts
Most tools ask you to connect Gmail or add a custom SMTP.
But that comes with problems:
→ API errors
→ Gmail sending limits
→ Broken email tracking
→ Poor deliverability
With PenguinMails, you skip all that.
You're not connecting, you're creating. Our inboxes are made to send cold emails, not handle newsletters or personal mail.
No Gmail logins or SMTP errors. Just email accounts that send and receive cold emails, without breaking or disconnecting.
You get better control, cleaner tracking, and better results.
Create and Use Mailboxes in 3 Simple Steps
Connect Your Domain
Connect your domain with PenguinMails and set up the necessary DNS records. Just like you would when setting up email hosting. We provide proper guides and tutorials for each and every step.
Step #1
Create Mailboxes
Click "Create Mailbox" to set up inboxes like [email protected]. These are full domain-based email accounts. You don’t need Gmail or SMTP.
Step #2
Start Sending Cold Emails
Use these inboxes to send, receive, and track your campaigns. These are real cold email inboxes, ready to go.
Step #3
You don’t bring inboxes from outside; you create them here. Real email accounts for cold outreach, made inside PenguinMails.
Does It Work Like Gmail or Outlook?
Yes, These Are Real Email Accounts
These are not fake inboxes or aliases.
You’re creating real mailboxes on your own domain, not just connecting someone else’s.
That means you can:
-
Send and receive cold emails
-
Check your inbox
-
Track replies
-
And manage it all from one place
Just like Gmail or Outlook, but made for cold email.
And unlike Gmail, there are no massive sending limits, no API errors, and no account bans.
Your email account lives inside PenguinMails, and works like a real inbox, because it is one.
Create Unlimited Mailboxes on Your Domain
(Free With Any Plan)
Most cold email tools limit how many inboxes you can use, or charge extra for each one. But PenguinMails gives you unlimited mailboxes at no extra cost.
You can create mailboxes directly inside your dashboard. Each one is a full cold email inbox that works just like Gmail or Outlook.
All inboxes are domain-based email accounts. Just connect your domain once, and start adding new addresses like [email protected] or [email protected].
And yes, they’re free mailboxes. You don’t pay extra, no matter how many you create. That means zero email hosting cost, even if you're running large campaigns with multiple senders.
Save $2,000+/Year by Creating Mailboxes
Instead of Buying Them
Running cold email campaigns at scale? You’ll probably need 20–50 inboxes.
With other tools, that means buying accounts from Google or Outlook and using SMTP integration to connect them. But that adds up fast, in cost and in tech issues.
Let’s break down the email hosting cost.

Frequently Asked Questions (FAQs)
Yes. These are new email accounts, so you must warm them up before sending cold emails.
Just like Gmail or Outlook, warming up helps your inbox build trust and land in inboxes, not spam.
