How to Build a Messaging App Like Textline

Today, businesses rely on instant communication, either to engage customers or to resolve queries without delay. This immersive dependence underscores the importance of an app like Textline, a solution for business-to-customer conversations. Such apps help businesses replace slow email threads and missed calls with clear conversations that customers prefer. Therefore, a brief outline of the app development process, including benefits and cost considerations, is provided below for reference.

What is Textline?

Textline app is a business texting app that allows companies to send and receive text messages with their customers. Without using personal numbers, teams can communicate with their customers via messages during working hours. This app is made for organizations and their teams, not for customers to download.

Customers can continue using their normal texting app, while the companies use the Textline app to read and reply. To keep it simple, Textline’s mobile app turns a smartphone into a portable customer messaging hub. Hence, the work text remains organized and separate from personal messages while still being easy to use.

Key Features of a Textline Messaging App

To value a business messaging platform, it’s important to look beyond the interface and focus on the functionality. With this foundation in place, explore the key features of the Textline conversation app that make messaging customer-focused:

1. Syncs with Web and Devices

The app syncs with the Textline web service to send and receive messages on desktops. Moreover, it helps keep conversations up to date across your phone, computer, and team without missing anything.

2. Team and Multiple Numbers

Textline allows many teams and departments to share one or more business phone numbers. This way, each agent has an account, but customers always see a single, consistent business number.

3. Manage Conversations

Assign conversations to specific teammates so everyone knows who should respond to each customer. Plus, its internal “Whispers” allow staff to add private notes inside the chat that only teams can view.

4. Fast, Consistent Replies

Shortcuts let you save and reuse message templates for common replies, keeping responses consistent. Furthermore, an address book stores customer details and notes, making it easier to personalize messages.

5. Alert and Availability Capability

Instant notifications alert you on your phone or desktop whenever a new customer message arrives. Additionally, you can set auto-responses for greetings and after-hours messages, along with away/available status options.

6. Allows Scheduling a Message

Teams can draft a message now and schedule it to be sent at a future time. This way, you can plan various reminders, follow-ups, and even decide on announcements in advance.

7. Facebook Messenger Inbox

Your Facebook page can be added as an extra department, where Facebook messages can be created just like SMS chat.

8. NPS SMS Surveys

This app can send Net Promoter Score (NPS) surveys by SMS, allowing customers to respond quickly to business recommendations.

9. Integrations With Other Apps

You can integrate it with platforms such as Zendesk, Slack, and Zapier, enabling Textline messages to trigger actions in your other systems.

How Does Textline Work?

As elaborated, the Textline app allows business teams to send and receive customer text messages from their phones. Here, everything is synced with the main Textline account, where team members can see the shared business inbox. Hence, once logged in, they can reply to messages at any time, as long as they have Wi-Fi.

How It Works for Customers

Customers don’t install or use Textline login; they simply text your dedicated business using their normal texting app. Their messages are delivered into your Textline account, and your replies appear to them like a regular SMS message. Therefore, the working on customer’s side is simple and doesn’t require any special setup or learning curves.

How It Works for Your Team

Your business staff downloads the app from the App Store or Google Play and signs in with their Textline credentials. Additionally, they get a shared mobile space to read, manage, and respond to customer messages in real time. For businesses, it’s a secure way to engage with customers in the field or away from the office.

Connectivity and Compliance

The app requires an internet connection (Wi-Fi or data) to sync messages with Textline’s servers in real time. This allows employees to stay compliant while texting business contacts from anywhere around the globe.

Key Components Needed for a Textline-Like App

Before the technical architecture for a Textline competitor, consider the listed fundamentals that will help you shape a better solution:

1. Shared Inbox and Conversation Management

A shared team inbox is essential, where all incoming customer messages are visible to multiple agents for review and response. Moreover, the ability to add private comments to threads can help teams collaborate on customer concerns. Proper logical assignments to specific agents or departments should be determined by rules such as availability.

2. Contacts, List, and Segmentation

There should be a well-constructed address book for storing customer details, history, and notes associated with their phone numbers. Additionally, tools to import contacts via CSV or sync from external systems such as CRMs. Tags or locations should be used to precisely group contacts to support targeted campaigns and announcements.

3. Real-Time Communication with Customers

You can use ZEGOCLOUD to integrate real-time communication APIs, including video and voice calling. This way, teams can incorporate direct, high-quality one-on-one calls with any specific customer for a serious query. Furthermore, you can create a separate room and start a group call with multiple customers with the same query. The adoption of mass texting makes announcements easier, addressing many customers at once.

4. Survey, Metrics, and Analysis

For SMS surveys, use built-in NPS or CSAT surveys sent via text messages to capture feedback. Make use of performance dashboards, where metrics for messages, response times, and agent performances can be analyzed. In addition, the ability to export reports or push statistics to BI tools can be incorporated to enable deeper analysis.

5. Automation and Productivity Features

As with the Textline sign-in, the messaging app should include templates for frequently asked questions to speed up replies. Plus, rules for out-of-office replies, after-hours messages, and instant confirmation for customer texts. The ability to schedule texts for later or activate alerts for an automated send based on events or routes.

Plan for real-time updates, high availability, and horizontal scaling, allowing the system to grow from a few teams to thousands.

3. Add Automation and Productivity-Focused Tools

Start with core productivity: templates, scheduled messages, and simple keyword or time-based auto-responses. Later, build visual automation flows for reminders, drip campaigns, and lead sequences that mix SMS and other channels. Afterward, incorporate a visual automation builder that lets users drag and drop steps without requiring developers’ assistance.

4. Incorporate One-on-One Chatting with ZEGOCLOUD

Use ZEGOCLOUD In-App Chat SDKs to create a one-on-one chat space for a specific customer privately. You can even create unlimited open channels and send messages to connect hundreds of users. Additionally, add a group chat button directly within the chat to enable real-time conversations with multiple clients. Its pre-installed UIKits provide ready-made screens for call invitations, screen sharing, and virtual backgrounds.

5. Design and Build Client Apps

For web apps like Textline, follow a familiar shared-inbox pattern: left panel for inbox and filters, center for conversations. Include UX details such as keyboard shortcuts, quick actions, and inline tagging to reduce friction for heavy users. However, for mobile, prioritize a fast chat screen, reliable push notifications, and simple status changes (away/available).

6. Test Thoroughly and Monitor

Finally, set up automated tests (unit and end-to-end) and run a load test that simulates spikes in messages. Additionally, adding observability and alerts enables engineers to quickly detect and resolve issues in production. Most importantly, collect structured feedback from early customers and watch how they actually see the app.
