Needing to send required information to an unengaged profile

Hi all

I need some advice with regard to how to send necessary company updates (pricing update info) to customers I have suppressed due to low engagement. 

We send one marketing newsletter once a month, and we regularly move unengaged profiles to the suppressed list… However, annually we need to update our trade customers with our pricing information / file. 

Whilst it is fine for us to not get them the info if they are unsubscribed, we do need to attempt to send the pricing update to them, and if I have chosen to suppress them due to inactivity, that is unhelpful for them if they do wish to receive the annual pricing update info.

How can i navigate this? Suppressed contacts for one type of messaging, but necessary to receive another… and currently they’re not tagged as trade. 

I am thinking that I need to:

• import the list of trade customers without updating their subscription status allowing me to ‘tag’ them as trade
• set up a segment of ‘trade’ and ‘suppressed’
• reimport the new segment as ‘subscribed’
• then suppress them again?

Advice would be great.. as i am probably over complicating it, but new to Klaviyo and previous platforms wouldn’t allow you to reimport an unsubscribed contact so this wasn’t an issue. It looks like Klaviyo ignores unsubscribes when you reimport them. 

Thanks in advance!
