Back-in-stock pings work when they are timely and optional. Spammy urgency trains unsubscribes.
Consent is the product
Only alert people who asked for that SKU. Broad "everything is back" blasts burn trust.
One SKU, one message
Include size/color, price if changed, and a direct link. Skip stacked upsells in the same ping.
Timing windows
Send soon after restockβnot three days later when ads already moved on.
Handle the reply surge
Stock alerts create "is this authentic / shipping?" questions. Staff the inbox.
Helpful alerts feel like a favor. Automate them carefully in Connectora Sync.
