Teams in Slack work together in channels that can be organized by project, department, office location, or anything else, really. This makes it easy for users to follow the topics that are important to them. Public channels are open to anyone on the team so marketing can see what designers are working on, sales can see what’s on the product team’s roadmap, and new hires can easily get up to speed instead of starting with an empty email inbox. \n\nSlack connects to the tools and services that businesses already use and centralizes the notifications, files, and data from hundreds of different applications. This means no more searching through emails for that one follow-up, constantly switching between different tabs and dashboards, or juggling dozens of tools - each with their own login. Slack helps teams work smarter by providing all of the information and context needed to make effective decisions quickly. \n\nEverything shared in Slack is automatically indexed and archived so that companies can create a comprehensive knowledge base with zero effort, simply by working in Slack. And, Slack’s search makes it easy find the information users need, whenever they need it.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/6e4849f1-8a0f-4dcb-9db2-e2cb8eaf92c1.png","url":"https://www.getapp.ca/software/91563/slack","@id":"https://www.getapp.ca/software/91563/slack#software","@type":"SoftwareApplication","applicationCategory":"BusinessApplication","publisher":{"@id":"https://www.getapp.ca/#organization"},"aggregateRating":{"@type":"AggregateRating","ratingValue":4.7,"bestRating":5,"ratingCount":24103},"offers":{"price":"8.75","@type":"Offer","priceCurrency":"USD"},"operatingSystem":"Cloud, Apple, Windows, Android, Platform ios, Platform ipad"},{"name":"Viber","description":"Viber is a mobile messaging platform, which helps businesses communicate and run promotional campaigns via one-to-one chats, video calls or text notifications.\n\nViber lets users call and message each other over Wi-Fi or internet connectivity. The application also allows marketers to utilize multiple placements options to run advertisements. The messaging platform lets users share images, files, and audio from any device such as desktops, laptops or smartphones. \n \nViber also allows marketing teams to improve audience engagement and brand awareness through its sticker content functionality.
