You open it from the Extensions Portal. Anyone who can see the **QB Courier** tile in **Browse Extensions** can open and use it. It has three sections: | Section | What you do there | | --- | --- | | **Courier Configurations** | Create, edit, duplicate, and test the configurations that tell Courier what to send, to whom, and when. Run On Demand configurations and see each configuration's activity. | | **Mail Servers** | Optional. Add your own mail server (SMTP, Gmail, or Office 365), so emails come from your own address instead of Courier's shared sender. | | **Email Message Subtables** | Create reusable tables of related records that you can add to any Courier email. | To learn how Courier processes and sends emails, see [Overview of QB Courier](/quickbase-extensions/docs/courier-for-quick-base-overview). ## Open the Courier Configurator 1. Sign in to the [Extensions Portal](/quickbase-extensions/docs/juiced-cloud-overview) and select your company. 2. Open the **QB Courier** extension's page: select its tile in **Browse Extensions**, or select **Open** next to it on **My Extensions**. 3. At the top of the page, select one of the three buttons. Each opens the configurator at a different section: | Button | Opens | Also shows | | --- | --- | --- | | **Configurations** | Courier Configurations | How many configurations you have of each kind: **Scheduled**, **On Demand**, and **Trigger** | | **Mail Servers** | Mail Server List | The total number of mail servers | | **Email Message SubTables** | Email Subtable list | The total number of subtables | The configurator opens in a window inside the portal. See also [Extension tiles and pages](/quickbase-extensions/docs/add-on-tile-info#extension-specific-panels). ## Move between sections - The configurator has no side menu. Use the buttons at the top of each list: - **Courier Configurations** list: **Mail Servers** and **Email Message Subtables**. - **Mail Server List**: **Courier Configurations** and **Email Message Subtables**. - **Email Subtable** list: **Courier Configurations** and **Mail Servers**. - If you leave the Configuration, Email Options, Email Message, or Email Attachments tab with unsaved changes, your browser asks *Discard changes?* Select **Cancel** to stay on the tab and save your work. ## Close the Courier Configurator - Select the **X** at the top right of the window. Clicking outside the window or pressing **Esc** doesn't close it. - When you open it again, it starts fresh at the section you choose. Save your changes before you close it. ## If the configurator doesn't open The portal shows one of these messages: - *We were unable to determine which company you are working with.* Select your company from the **COMPANY** dropdown at the top of the portal, then try again. - *Invalid response from server.*, *Unable to send token to Courier app.*, or *There was a problem showing the Courier configurations.* Close the window and select the button again. If a list is empty when you expect items in it, close the window and open it again. If the problem continues, open a [Quickbase technical support case](https://help.quickbase.com/docs/get-help-from-quickbase-technical-support). ## What's in this section - [Courier Configurations list](/quickbase-extensions/docs/courier-configurator-configurations-list): search, filter, duplicate, Execute Now, and authorize new apps. - [Create or edit a configuration](/quickbase-extensions/docs/create-or-edit-a-configuration): the six tabs, and View Limits. - [Configuration activities](/quickbase-extensions/docs/courier-configurator-configuration-activities): run history, Processing Details, and resending triggered emails. - [Mail servers](/quickbase-extensions/docs/courier-configurator-mail-servers): send from your own mail server, including Gmail and Office 365. - [Email Message Subtables](/quickbase-extensions/docs/courier-configurator-email-message-subtables): reusable tables of related records.
