No Gmail. No SMTP.

Don’t rent one. Own it.
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.
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.
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.
Click "Create Mailbox" to set up inboxes like [email protected]. These are full domain-based email accounts. You don’t need Gmail or SMTP.
Use these inboxes to send, receive, and track your campaigns. These are real cold email inboxes, ready to go.
You don’t bring inboxes from outside; you create them here. Real email accounts for cold outreach, made inside PenguinMails.
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:
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.
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.
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.

You’re getting unlimited mailboxes. These are real, domain-based email accounts, not temporary or shared inboxes.
Instead of buying inboxes, you create mailboxes inside PenguinMails. They're free mailboxes, fully included with your plan.
So you save money, skip hassle, and run more outreach, without limits.
Every cold email mailbox you create comes with built-in controls.
You don’t need to open cPanel or contact support.
You can:
You’re not just creating mailboxes, you’re in full control.
And yes, all this works with unlimited mailboxes, included in every plan.
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.
Yes. You’ll need to connect your domain first before creating mailboxes.
This includes setting up DNS records (we guide you), and it’s a one-time step per domain.
If you pause a mailbox, it stops working, but your data stays safe.
Even if you delete a mailbox, we don’t instantly erase the data.
Emails always stay in our system for a short time, giving you the option to restore them.
However, if we delete your private VPS (if you stop working with us) then recovery isn’t possible, but we'll notify you and give you options to export data.
Yes. Storage is shared across all mailboxes under your plan.
Here’s how it works:
Plan 1 → 1 GB
Plan 2 → 2 GB
Plan 3 → 4 GB
Plan 4 → 7 GB
1 GB = about 100,000 emails (sent + received).
If you hit the limit, you can either delete old emails or buy +1 GB storage for just $2.
Yes. All mailboxes are fully encrypted with SSL/TLS, and hosted on secure servers.
Your inbox is private, no one (not even us) can read your emails.
Passwords are hashed, and accounts are protected with strong access rules.
If your domain expires, all connected mailboxes will stop working, you won’t be able to send or receive emails.
Your data stays safe for a short time, until your private VPS stays. We assign separate VPS and IPs to every user.
Just reconnect or renew your domain to start using mailboxes again.
No. Right now, these mailboxes only work inside PenguinMails.
But soon, we’ll offer a separate service that lets you create mailboxes and use them anywhere, like a Gmail/Outlook alternative.
Two-factor authentication (2FA) applies to your main account, not individual mailboxes.
No hosting. No SMTP. No cPanel.
Just connect your domain and click “Create Mailbox.”
You’ll have a working cold email inbox, ready to warm up and send.
