Última atualização em April 22, 2024

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.

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

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.

Key features

  • 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.

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.

Key features

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.

12. Zoom

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.

It supports audio, video, text, file sharing, and more—making it possible to communicate and engage with customers in whatever way they prefer.

Key features

  • 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.

14. Slack

Slack for customer support

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.

Key features

  • 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.

Key features

  • 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.
