It looks like the email you are referring to is in the newest version of our editor. We do not have a specific PayPal button for this editor. However, you can upload an image of a PayPal button and use that to link to your payment page. I can definitely pass along your feedback that you'd like to see the PayPal button added back in to our product, though. Thank you for your understanding.
Thank you for your feedback!
In this case I suggest creating your own payment button and linking that to your payment account. Click Here for more information on creating/inserting a button into our new editor.
Thanks and have a great day!
