Top 15 communication apps for customer service
Talk to customers like friends on the communication apps they know and love.
Last updated March 18, 2022
In the early 2000s, the thought of companies connecting with customers over communication apps would have seemed ludicrous. But in 2022? That’s the norm.
According to the Zendesk Customer Experience Trends Report 2022, inquiries over social messaging apps like Facebook Messenger and WhatsApp jumped 36 percent last year—higher than any other channel. This trend is here to stay, as consumers are increasingly turning to their favorite messaging platforms to connect with companies.
But it’s tough to know which communication app is the right choice because there are so many options available. We’re breaking down 15 different tools to help you pick the best one for your business.
What to look for in communication apps for customer service
First and foremost, find a communication app that’s simple to use. Your support agents and customers won’t want to deal with a complex tool.
Beyond ease of use, consider these other key factors when looking for an app:
- AI and automation. An app with these features can simplify internal workflows and reduce manual tasks, allowing your reps to spend more time with customers.
- Popularity. Choose a communication app that your audience already loves. If your target customers are loyal to a particular app, they’ll feel comfortable using it to reach out for support.
- Onboarding and support. There’s always a learning curve when adopting new technology. Minimize this friction by picking a communication app that offers an onboarding program and ongoing support and training for your team.
- Integrations. Find a tool that integrates with your existing tech stack so all your customer information is in one place.
- Goals. Whether you’re trying to reach more consumers or improve your conversational customer service, pick an app that aligns with your business objectives.
Once you’ve narrowed down your options, consider signing up for a free trial or piloting the app with a small group of customers. The experience will help you determine whether the communication app is a good fit for both you and your buyers.
The best communication apps
Best mobile chat apps
These mobile communication apps take the traditional text messaging experience to another level with additional capabilities and rich features that are ideal for providing customer support.
1. WhatsApp Business
With more than 2 billion users, WhatsApp Business is probably familiar terrain for your audience. Our research shows that more and more customers are using WhatsApp as a support channel—the volume of tickets submitted over WhatsApp skyrocketed 370 percent last year.
There are two options for businesses looking to connect with their customers: the WhatsApp Business App and the WhatsApp API.
The WhatsApp Business App looks just like a personal account on the platform, but it’s equipped with extra features for small-business owners. Contact numerous shoppers simultaneously with new offers and important information, and segment consumers to personalize your communication.
Opt for the WhatsApp Business API if you run a large business that relies on a CRM, contact center, or customer service software to engage with buyers. With the WhatsApp Business API, midsize and enterprise companies can reach their customers without the platform’s normal limits. The WhatsApp Business API also allows for more customization, integrates with other tools, and provides advanced security. You don’t have to figure it out by yourself, either—you can work with a developer and a WhatsApp Business Solution Partner to access the service.
- Quick replies. Save and reuse messages that you regularly send to customers for fast and efficient responses.
- Automated messages. Greet your customers instantly with pre-set messages that let them know when they can expect a response or where to find more information.

2. Apple Business Chat
Apple Business Chat gives your company an easy way to connect with the 1.65 billion people who use Apple devices. Your customers can find your business and initiate a conversation with you from Apple Maps, Safari, and Siri.
Apple Business Chat lets you send customers order status updates, location information, important materials, appointment reminders, high-quality images, and more. You can also receive payments from buyers via Apple Pay.

- Schedule appointments. Customers can set up meetings and appointments without having to open a separate app or browser window.
3. Google Business Messages
Google Business Messages allows customers to initiate a conversation with businesses directly from several Google platforms, including Maps and Search. Google occupies 92 percent of the search engine market share worldwide, so this messaging app is a key platform for connecting with customers. You can also use it to provide superior customer service.
Google Business Messages helped clothing company Levi Strauss keep its customers happy during tough times. The brand needed a way to connect with customers when the pandemic prompted a 30-percent increase in off-hours shoppers. Google Business Message allowed customers to reach the company without visiting the website, going to a store, or making a phone call. The result was higher customer satisfaction scores and 30x more store-related questions resolved.

Coca-Cola experienced over 680,000 chatbot interactions on Viber through its special Sticker Pack promo, with 29,000 codes redeemed.
While it’s free to communicate with other Viber users on the app, you’ll need to use Viber Out to contact people who don’t use the platform. Rates depend on the country, phone number, and type of plan you’re using.

10. Instagram Direct
Ninety percent of Instagram users follow a business account, making the app one of the top places for companies to reach customers, cultivate loyalty, and increase sales. Instagram Direct, an inbox where you can send and receive private messages, has proved to be an efficient customer service tool.
As customers view your Instagram photos, Reels, and Stories, they can easily click to message you for more information or ask questions. Businesses can also use ads to prompt customers to message them for personalized offers. Starbucks Indonesia was able to reach a 6x return on ad spend by running ads that linked to Instagram Direct.
Setting up an Instagram Business account is free. Similar to WhatsApp and Facebook Messenger, businesses can use the Messenger API for Instagram to handle customer conversations at scale.
- Quick contact options. Add a “message” button to your IG business profile (or use an IG.me link on your website) to make it easy for customers to connect with you on Instagram.

The fast-paced, conversational nature of Twitter makes it a perfect platform for helping customers. You can reply to a customer’s tweet, seamlessly move public conversations to a private inbox, and share helpful resources with your audience.
Consumers enjoy using Twitter to connect with companies, too. According to a survey by Twitter and Sprinklr, two out of three people prefer Twitter over other social networks for customer support.

Best voice and video communication apps
Sometimes, chatting through a problem via video or audio is the best way to provide great customer service. While many of the other apps on our list have video features, these apps set themselves apart thanks to their audio-visual focus.
According to Business of Apps, “Zoom was one of the fastest-growing apps of the pandemic, with meeting participants increasing by 2,900 percent.” As one of the most popular video platforms, Zoom is an ideal place to connect with customers.
Zoom allows you to do voice calls or video conferencing with one customer or hundreds all at once. It’s also simple to share your screen and send messages and links in the chat throughout the meeting.
Zoom has pricing tiers ranging from a free plan to enterprise-level plans at $240 per year, per license. There are a few other options for large groups and audio conferencing, too.
- Recording. Zoom allows you to record and save meetings for your customers to rewatch. You can also share them with your support team for internal training.
- Screen sharing. Support agents and customers can walk through solutions together by screen sharing during a video call.
- Easy scheduling. Schedule and track meetings directly from the Zoom desktop app (or use scheduling tools like Google Calendar and Outlook). Zoom also integrates with Zendesk, so you can schedule and launch a meeting right from a support ticket.
Originally designed with streaming and gamers in mind, Discord is a growing platform among young audiences. It’s also a great place to provide customer service.
Boasting 300 million registered accounts, the app enables businesses to create different servers (or channels) to separate conversations by specific customers, teams, or projects. It supports audio, video, text, file sharing, and more—making it possible to communicate and engage with customers in whatever way they prefer.
- Screen sharing. Like Zoom, Discord allows you to easily share your screen with customers and vice versa. If needed, you can even multi-stream and view screens from several customers at the same time. This can be helpful when trying to solve a complex or company-wide issue impacting multiple users.
- Quick switcher. This tool lets you jump between messages and servers via the CTRL+K or CMD+K keyboard shortcut, so you can respond to customers with just a quick click.
- Integrations. Discord has many integrations, including Twitch and YouTube. With the Zendesk integration for Discord, you can use ticket forms to gather information and add a chatbot to address customer questions on the platform.
Internal communication apps
Excellent customer service starts with smooth communication inside your company. Reps should be able to quickly communicate with fellow support agents and internal experts so they can provide customers with fast responses. The following internal communication apps will help you deliver that speedy, efficient service.
Over 12 million people use this communication app daily. Slack strengthens support teams by giving agents a single space to ask each other questions and share information. Teams can even create dedicated channels for high-priority clients and get automatic alerts when tickets come in.
Externally, businesses can set up a Slack community for customers, where they can answer questions and share key resources. They can also create a public channel to serve as a customer knowledge base.
- Bots and automation. Stay on top of your workflow with automated responses and processes. For instance, you can have a bot remind you to follow up on a ticket.
- Integrations. Slack integrates with hundreds of different apps—including Zendesk. Thanks to these integrations, all your tools can work together to speed up response and resolution times.
- Channels. Create multiple public or private channels within your workspace, or use Slack Connect to share channels with people outside your company. Use Slack’s search bar and filters to easily find information within channels.
15. Microsoft Teams
Like Slack, Microsoft Teams is a shared digital workspace. It offers numerous features—including shared channels, instant messaging, and video calls—that help support agents collaborate when solving customer issues.
Reps can also use Microsoft Teams to communicate directly with customers. REI, for example, holds “virtual outfitting” sessions via Teams, where they bring in customers for a digital shopping experience. Similarly, support teams can offer customers one-on-one product training or troubleshoot issues using Teams.
- Integrations. Save time and enrich internal and external communications by integrating Microsoft Teams with popular apps, such as Zendesk, Trello, Asana, and more.
- Team channels. Set up private spaces where your support agents can quickly share files, customer notes, and updates.
- Easy ideation. Encourage brainstorming and collaboration via the Whiteboard app—then save everyone’s ideas.
Keep the conversation going
Choosing the right business communication app is a great first step. Once you’ve decided on a platform, it’s time to take advantage of the speed and simplicity of these apps and provide your customers with rapid support.
