# How to Add Mailboxes to a Domain You Already Own

Learn how you can add mailboxes to a domain you already own

Already have a domain purchased through SmartSenders?

You can add more mailboxes to it directly, without buying a new domain or paying a domain fee.

### **Here’s how to add mailboxes to a domain you own:**

From the left sidebar, click **_Sender Accounts_** _»_ **_Email Accounts_**_._

In the top-right corner, click **Purchase**.

This opens the mailbox purchase modal.

You'll see two options:

-   **Pre-Warmed Mailboxes**
    
-   **Fresh Mailboxes**
    

Click **Get Fresh Mailboxes**.

Fresh mailboxes allow you to:

-   Start with brand-new inboxes
    
-   Control the sending strategy
    
-   Warm them gradually for long-term deliverability

If you're looking to buy pre-warmed mailboxes, here's a [guide](https://helpcenter.smartlead.ai/en/articles/429-pre-warmed-mailboxes-by-smartlead.md) to help you get started.

Click on **Add Mailboxes option.**

On the next screen, select **Add mailboxes to existing domain** and click **Add Mailboxes**.

This option has no domain fee - you only pay per mailbox, and it preserves the domain's existing warmup reputation.

Search or browse your domains, then select the one you want to add mailboxes to.

Use the filter icon to narrow the list by domain health (Healthy / At Risk / Near Expiry) or by how many mailboxes a domain already has.

Choose how many mailboxes to add - the screen shows how many additional mailboxes that domain can still take, based on its current mailbox count.

You can also choose which domain(s) to apply it to, using the All Domains dropdown.

Once done, click **Continue**.

Note: some words aren't permitted in sender names and will show a validation error if used.

Review your order. The **Cost Summary** shows **Domain fee: FREE** (no new domain purchased) plus the monthly mailbox cost, then click **Complete Purchase**.

These new mailboxes join the domain's existing monthly subscription and are billed pro-rata for the rest of the current billing cycle, and will be delivered within **24-48 hours**.
