Subscription failed / refund emails do not easily identify the channel.
Subscription reminder emails received an update (per https://twitch.uservoice.com/forums/310231-subscriptions/suggestions/43444125-subscription-reminder-emails-lack-critical-informa ) but other types of subscription emails do not display this information directly.
For payment declined notifications this information IS in the attached invoice (at the very bottom) but requires the extra step of accessing the invoice to get the name.
For refund notifications, this information does not appear to be included AT ALL (only an invoice reference for the original transaction, requiring search for the original email.)
As such, in the event of card problems (like card getting blocked for security, etc.) it is difficult to tell quickly and at a glance which subscriptions may be affected.
Only a small thing in the scheme of things, but when one email template was changed to include this, why not include this information in other templates?
