Hi @CaptainMike, 

Thanks for the question! A winback flow or re-engagement campaign could be helpful, depending on your specific use case. I’ve included some differences between the two below: 

Winback: 

• a series of emails sent to customers who previously engaged with your brand, but have not interacted with you for a certain period of time
• triggered by the Placed Order event and sends when a certain amount of time has passed after the purchase

Re-engagement:

• a one-off email rather than a sequence of emails
• should only be a single email that is sent infrequently to those who are not going to receive a winback flow (once a year is a good rule of thumb)

If deliverability is a concern, I recommend taking a look at our understanding deliverability best practices article. Keep in mind that is is always important to keep your unsubscribe link prominent in any message. It’s both a legal requirement and the best way to prevent unengaged subscribers from hurting your deliverability.

I hope this helps you go down the right path. I’d love to hear from others in Community to see what’s worked well for them too!
