[Getting Started](https://support.postworks.co.uk/knowledge/fastrack?hsLang=en#getting-started) # How to apply Fastrack™ to letters ## Find out how to apply Fastrack™ to your letters for same day posting ### Before you begin Make sure Fastrack™ is switched on for your account and in your user permissions. If you’re not sure, contact your Account Administrator or email [support@postworks.co.uk](mailto:support@postworks.co.uk). - You need enough credit in your account to cover the charge, including VAT. - You can only apply Fastrack™ to letters in **Post Tray** or **Post Room** status. These are letters that haven’t yet been handed over to the delivery network. ### 1. Select your letters On the Postworks Send dashboard, click **Post Tray** or **Post Room**. ### ![Screenshot 2026-10-22 013515](https://support.postworks.co.uk/hs-fs/hubfs/Screenshot%202026-10-22%20013515.png?width=320&height=111&name=Screenshot%202026-10-22%20013515.png) Tick the box at the start of the row for each letter you want to send the same day. The number of letters you’ve selected is shown above the list. ![image-png-Oct-21-2026-06-02-06-5152-PM](https://support.postworks.co.uk/hs-fs/hubfs/image-png-Oct-21-2026-06-02-06-5152-PM.png?width=600&height=195&name=image-png-Oct-21-2026-06-02-06-5152-PM.png) ### 2. Apply Fastrack™ After you apply Fastrack™ or Fastrack™ Ultra, you can no longer recall those letters. Click the **Fastrack™** button. ![Screenshot 2026-04-14 095724-1](https://support.postworks.co.uk/hs-fs/hubfs/Screenshot%202026-04-14%20095724-1.png?width=160&height=50&name=Screenshot%202026-04-14%20095724-1.png) Check the charges, then click **Fastrack™ items**. ![Screenshot 2026-04-14 095801-2](https://support.postworks.co.uk/hs-fs/hubfs/Screenshot%202026-04-14%20095801-2.png?width=480&height=200&name=Screenshot%202026-04-14%20095801-2.png) #### Applying Fastrack™ Ultra (4pm to 5pm) Between 4pm and 5pm, the **Fastrack™** button turns yellow and applies Fastrack™ Ultra at £1.99 + VAT per letter. The steps are the same as above, but you’ll click **Apply** to confirm. Hover over the button to see how much time is left. ![button hover w message](https://support.postworks.co.uk/hs-fs/hubfs/button%20hover%20w%20message.png?width=320&height=278&name=button%20hover%20w%20message.png) ![image (6)-1](https://support.postworks.co.uk/hs-fs/hubfs/image%20(6)-1.png?width=480&height=207&name=image%20(6)-1.png) ### What happens next A Fastrack™ icon appears in the column next to the tick box for each letter. Hover over it to see who applied Fastrack™. ![Screenshot 2026-10-22 021239-976](https://support.postworks.co.uk/hs-fs/hubfs/Screenshot%202026-10-22%20021239-976.png?width=300&height=203&name=Screenshot%202026-10-22%20021239-976.png) ### Important information - If you select letters that already have Fastrack™ or Fastrack™ Ultra applied, you won’t be charged again. - Account Administrators can apply Fastrack™ to letters uploaded by other users. ### Troubleshooting **“Fastrack™ cannot be applied”** One or more of your letters isn’t in Post Tray or Post Room status, or the cut-off time has passed. After 5pm, letters are posted on the next working day. **“Insufficient funds”** Your balance doesn’t cover the charge, including VAT. Add credit to your account and try again. **The Fastrack™ button isn’t available** Check that you’ve selected at least one letter. If the button still can’t be used, ask your Account Administrator to check your permissions.
