# Connect Maildoso Mailboxes

# Connect Maildoso Mailboxes

## Purpose

This article is for teams who use [Maildoso](https://maildoso.com) to host email accounts and want to bulk-import those accounts into SuperSend as senders. You will get a personal access token from Maildoso, connect it in SuperSend, and add selected mailboxes in one flow.

## Prerequisites

- A Maildoso account with at least one **active** Maildoso email account to import.
- Permission to add email senders in SuperSend (the **Senders** flow).
- To **save** the token under **Admin** → **Integrations** first, you need permission to create team integrations (same as other sending-provider credentials).

## Step 1: Get your token from Maildoso

Maildoso issues a **personal access token** for API access. SuperSend’s forms label this value **Maildoso API Key** — it is the same credential.

1. Sign in to Maildoso.
2. Open **General** settings in the Maildoso app: [https://app.maildoso.com/settings/general](https://app.maildoso.com/settings/general).
3. Create or copy your personal access token and keep it private.

If Maildoso’s UI also exposes the token under **Settings → API Keys**, you can use either path as long as the token you paste into SuperSend is current and has access to the accounts you want to import.

## Step 2: Import mailboxes from Senders

1. In SuperSend, go to **Senders** in the left sidebar.
2. Click **Add Sender** → **Email Sender**.
3. On the method screen, click **Connect Your Own Mailboxes**.
4. Choose **Maildoso** (bulk-import mailboxes from your Maildoso account).

You will see **Connect Maildoso** with the short explanation: enter your Maildoso API key to import existing mailboxes as senders.

5. Either:
   - Pick a **Saved Maildoso connection** if your org already stored a key, or
   - Choose **Use a different API key**, paste the token into **Maildoso API Key**, and optionally leave **Save this key for future imports** checked (shown when you have no saved connections yet).
6. Click **Connect Maildoso**.

SuperSend validates the key and lists your Maildoso accounts. Unlike some other provisioning providers, **Maildoso does not use a workspace step** — you go straight from the key to the mailbox list.

7. On **Select Mailboxes to Import**, select the mailboxes you want.
8. Click **Add N senders** (the label reflects how many you selected; if none are selected, the button prompts you to select mailboxes).
9. When you see **Import Complete**, click **Done**.

Imported accounts appear under **Senders** → **Mailboxes**. SuperSend uses Maildoso’s SMTP and IMAP endpoints for those senders.

## Optional: Save the key in Admin first

Saving the token in the Integration Library lets teammates reuse it without re-pasting.

1. Go to **Admin** → **Integrations** → **Integration Library** tab.
2. Select a **team** from the team dropdown (required to open the library).
3. Optionally click **Sending Providers** to narrow the list.
4. Find **Maildoso** and click **Add**.
5. Enter the **Maildoso API Key** and complete the save flow in the panel.

After that, the **Add Sender** → Maildoso path can select that saved connection instead of a new key.

## Expected Result

- **Senders** → **Mailboxes** lists the imported Maildoso accounts.
- The bulk-import success screen shows how many senders were added, skipped (already existed), or failed.

You still need to attach those mailboxes to a **sender profile** before using them in a campaign. See [Create and Use Sender Profiles](https://help.supersend.io/en/article/create-and-use-sender-profiles-1g4rjqt/).

## Troubleshooting

- **Issue:** **Connect Maildoso** fails or shows an error when validating the key.  
  **Fix:** Confirm you copied the full token with no leading or trailing spaces. Generate a new token in Maildoso’s [General settings](https://app.maildoso.com/settings/general) if the old one was rotated or revoked.

- **Issue:** **Select Mailboxes to Import** shows “No mailboxes found.”  
  **Fix:** In Maildoso, confirm you have **active** Maildoso email accounts. Inactive or non-Maildoso accounts may not appear in the list SuperSend receives.

- **Issue:** Some rows **Failed** on the import summary.  
  **Fix:** Read the error text under **Failed imports** on the success screen. Fix the underlying mailbox or credential issue in Maildoso, then run the import again for the failed addresses.

- **Issue:** Mailboxes imported but campaigns don’t send.  
  **Fix:** Open **Senders** → **Sender Profiles**, add the new mailboxes to a profile, and assign that profile to your campaign. See [Senders Overview](https://help.supersend.io/en/article/senders-overview-vqg87v/).
