If you're using our new, updated gift sender experience, you can still easily access the old tools as needed. Use the navigation bar in the top righthand corner of your screen to access these tools by selecting "Legacy features" from the dropdown.
Next, decide if you want to access the old campaign tool (for gifting more than one person) or the old direct gifting tool (for gifting one person). Select the appropriate option from the pop-up and you'll be redirected to send gifts using the legacy tools.
