The Sendmux integration shows your account’s email activity inside the Spotzee Email Proxy Tool. Connect with a Sendmux API key to view delivery metrics, provider status, billing balance, and delivery logs.
The Spotzee view makes read requests to Sendmux. Provider configuration, routing rules, quotas and sending domains are managed in Sendmux. The smx_root_ credential is a root key, so store and rotate it with the care you give other account credentials.

​
What you can see in Spotzee

Once connected, the Email Proxy Tool inside your project has two tabs:
  • Overview: send activity for the last 24 hours, 7 days, or 30 days; provider counts; billing balance; and 30-day spend.
  • Logs: per-message delivery logs with status, provider, and text filters. See Sendmux delivery logs.
What you can do only on Sendmux.ai (not in Spotzee):
  • Add or remove SMTP, Gmail, or Microsoft 365 providers.
  • Configure provider quotas, routing rules, and traffic distribution.
  • Manage sending domains, tracking domains, and DKIM.
  • Run test sends, import providers via CSV, and configure groups.
For all of those, follow the link from the Spotzee Tool to your Sendmux dashboard.

​
Before you connect

You’ll need:
  • A Sendmux account at sendmux.ai.
  • A Sendmux root API key that starts with smx_root_. Generate one in the Sendmux dashboard; Spotzee uses it for read requests.
  • The Spotzee project admin role.

​
Connect Sendmux

1

Open the Email Proxy Tool

Inside the project, open Tools and pick Email Proxy (Sendmux.ai). If no API key is configured, you’ll land on a setup screen.
2

Paste your Sendmux API key

Paste the API key that starts with smx_root_ into the field and submit.
3

Validate

Spotzee validates the key against Sendmux. On success, the Tool refreshes and the Overview tab populates with your account data.
If validation fails, the key was rejected. Common causes: wrong key copied (must start with smx_root_), key revoked in the Sendmux dashboard, or insufficient permissions on the key. Generate a fresh key and try again.

​
What the Overview tab shows

The data refreshes when you reload the page or select Refresh. Use the provider filter on the Logs tab to narrow individual message rows.

​
Disconnect

Removing the API key disconnects the integration. Spotzee stops calling Sendmux and the Tool surface returns to the setup screen.
1

Open the Email Proxy Tool

Open Tools and pick Email Proxy (Sendmux.ai).
2

Disconnect

Use the disconnect action on the Overview tab. Confirm at the prompt.
Disconnecting removes the saved API key from this Spotzee project. Your Sendmux account and providers remain available in Sendmux. Reconnect by entering a key on the setup screen.

​
Rotating the API key

Two-step swap, like any credential rotation:
1

Issue a new Sendmux API key

On the Sendmux dashboard, generate a new smx_root_ key.
2

Reconnect Spotzee

In the Email Proxy Tool, disconnect the old key, then enter the new key on the setup screen. Spotzee validates it before loading your account data.
3

Revoke the old key

On Sendmux, revoke the old key once Spotzee is using the new one.
