WhatsApp is a multi-purpose messaging application that allows sharing of images, videos, and documents across Android, iPhone, and Blackberry devices. It has over 50 billion messages sent daily and does not require logging in or out. Some companies have used WhatsApp successfully for marketing, including an online retailer that updated customers on deals and an American food brand that engaged consumers for 65 minutes on average through a cooking campaign. However, WhatsApp lacks some enterprise features such as data protection, separating business and personal communication, and ecosystem integrations with other business software.
