Greece has high mobile use, and Viber is unusually popular alongside Messenger and WhatsApp. SMS is used for appointment reminders, deliveries and bank codes.
Card payments grew rapidly after the 2015 capital controls, and IRIS instant payments are now used for transfers. Tourism dominates the summer economy, so many businesses market in English and other visitor languages from April to October. Easter, the August holidays and Christmas shape domestic demand.
Greece's economy depends heavily on tourism, which brings over 30 million visitors a year to the islands, Athens and Thessaloniki, and on shipping: Greek owners control one of the largest merchant fleets in the world. Agriculture (olive oil, feta, fruit) and a growing technology scene add to this. The standard VAT rate is 24%. Law 3471/2006 requires consent for electronic marketing, supervised by the Hellenic Data Protection Authority. Many Greeks celebrate name days as well as birthdays, which gives retailers extra occasions for greetings and offers.
