Just adjusting my sneak peak email. How can I edit the subject and preview text for this email, if it is written into the code?

Drop in at 12 today if anyone wants to brain storm growth, product, tactics... https://www.skool.com/ooooby-growth/calendar?eid=1604a477838d455398e14d7eec703cb9&eoid=1785322800

The default is quite cold, even the sign off not in our voice. This is what I changed it to, simple edit. Hi {{ first_name }}, Your {{ hub_name }} delivery has been successfully cancelled, effective {{ cancellation_date | date_format_short }}. A note before you go. If you only meant to take a break, our holiday feature does exactly that, and takes about a minute to set up. And if the cost was the issue, reply to this email and we might be able to find a way to make it work, whether a smaller box, using a pick up point etc. {{~ if is_scheduled_payments_cancelled -}} All existing scheduled payments have been cancelled. {{~ end -}} Any outstanding balance will be collected in our next billing cycle. Warm wishes, {{ hub_name }} team _Grown · Seasonal · Cornish_
