What delivery timeframes should I promise internationally?

Be realistic: express services (DHL/FedEx/UPS) typically deliver in 2-5 business days internationally. Economy/postal services take 7-21 days. Customs clearance can add 1-5 days on top. Always under-promise and over-deliver. 67.5% of shoppers won't return to a store that misses delivery promises. Swap's real-time tracking gives customers accurate visibility.
