Hi all,

I am trying to wrap my head around the one-click unsubscribe requirement for “triggered flow emails”.

We use Klaviyo for our promotional emails but then send transactional / triggered flow emails through an API and our own custom email sending platform.

I know Klaviyo will add a one-click unsubscribe to all emails that aren’t true transactional emails.

But what about triggered flow emails like the welcome series. product review flow, abandoned cart flow, etc.

I have read a lot of mixed info on this now with some saying that these are transactional emails and don’t need an unsubscribe and some saying that they do in fact need an unsubscribe. I talked to Klaviyo support and they said they will add the unsubscribe automatically to all marketing flow emails.

Since we are sending triggered emails via our own custom platform I want to make sure we are doing it right.

Is a one-click unsubscribe or an unsubscribe in general needed for the welcome series, product review flow, abandoned cart flow, etc to adhere to the new Google and Yahoo requirements?
 

If yes, will that unsubscribe option have to unsubscribe people from all communications (not including true transactional emails, im thinking order confirmation, shipping updates, form submission confirmations, etc here)? Or can it unsubscribe someone from receiving the specific flow they are unsubscribing from? For example, lets say we have to add an unsubscribe to the product review flow, should that unsubscribe button remove the user from all email communications or just the specific product review flow?

I appreciate everyones help since i have been looking for hours and haven’t found any good info on this.
