Best SMS App | SMS Text Message Automation

SMS is still one of the most reliable ways to reach people. Emails get ignored, push notifications get muted, and chat tools depend on users being online. A text message, however, is almost always seen within minutes. For businesses, this makes SMS a powerful communication channel but only if it is used correctly. Manually sending messages does not scale, and one-off SMS campaigns rarely deliver consistent results. The real value of SMS emerges when it is automated and connected to the tools teams already use.

Today, companies use SMS to:

• Notify customers about completed tasks or requests

• Remind users to submit documents before deadlines

• Alert internal teams about urgent updates

• Support sales, support, and marketing workflows

In this article, we’ll look at the best SMS apps for business use, including NetGSM, Textlocal, Twilio, MessageBird, JustCall, Aircall, and Pushbullet, and show how they can be combined with Monkedo, a no-code automation platform, to build practical SMS automations without writing code.

We’ll also walk through five real-world SMS automation scenarios, covering customer notifications, internal alerts, marketing messages, and partnership workflows.

Best SMS Apps

Choosing the right SMS app is a critical step when building reliable text message automation workflows. While consumer-facing messaging apps like Google Messages, iPhone Messages, WhatsApp, or Samsung chat apps focus on personal communication, business SMS tools are designed for sending messages programmatically, integrating with other systems, and delivering notifications at scale.

In this section, we cover some of the most widely used SMS and messaging apps in 2025, each offering different strengths for sending messages, notifications, reminders, and system alerts. These apps are commonly used in combination with automation platforms and integrations to connect CRM systems, forms, work OS tools, or marketing software with SMS messaging.

NetGSM

NetGSM is a Turkey-based SMS app and messaging service provider focused on business SMS delivery. It allows companies to send text messages via API integrations, making it suitable for automated notifications, reminders, and transactional messages. NetGSM is commonly used for compliance-friendly SMS communication, including sender ID management, delivery reports, and encrypted message transmission where required by regulation. It is primarily preferred by businesses operating in Turkey that need reliable local SMS delivery and system-to-SMS integrations.

Textlocal

Textlocal is an SMS messaging platform designed for sending bulk and transactional text messages across multiple countries. It provides tools for SMS campaigns, scheduled reminders, and automated notifications through API and dashboard-based messaging. Textlocal is often used by businesses that need a straightforward texting app for sending messages at scale, with features such as message templates, delivery tracking, and contact management. It is commonly integrated into forms, CRM systems, and notification workflows.

Twilio

Twilio is a global communications platform that enables developers and businesses to send SMS, voice messages, and chat messages through APIs. It is widely known for its flexibility, deep integration capabilities, and support for SMS, WhatsApp, and other messaging channels. Twilio is frequently used for automated text messages, OTP delivery, notifications, and two-way messaging workflows across Android, iOS, and web applications. Its API-first approach makes it a common choice for large-scale and international messaging systems.

MessageBird

MessageBird is a cloud-based messaging and communications app offering SMS, voice, and chat messaging through a single platform. It supports sending text messages globally and integrates with business systems via APIs and automation tools. MessageBird is often used for customer notifications, reminders, and multi-channel messaging strategies, including SMS and WhatsApp. Businesses prefer MessageBird when they need centralized message delivery, reporting, and customization across regions.

JustCall

JustCall is a business communication app that combines SMS texting and calling features in one platform. It is primarily used by sales and support teams to send text messages, follow up with leads, and manage customer conversations. JustCall integrates with CRM systems and helpdesk tools, allowing automated SMS notifications and reminders linked to customer records. It is commonly preferred by teams that rely on SMS as part of daily customer communication workflows.

Aircall

Aircall is a cloud-based phone and messaging app built for support and sales teams. In addition to calling, it supports SMS messaging for notifications, follow-ups, and internal communication. Aircall integrates with CRM and helpdesk tools, enabling automated SMS messages triggered by system events. It is often used by teams that want structured communication, call tracking, and messaging combined in a single platform.

Pushbullet

Pushbullet is a cross-device messaging and notification app that allows users to send and receive SMS messages from their desktop by syncing with Android devices. It also supports push notifications, links, and file sharing. Pushbullet is commonly used for personal productivity, internal alerts, and lightweight SMS notifications rather than large-scale customer messaging. It is preferred by individuals and small teams who want quick message delivery and device-to-device integration.

Text Message Automation with Monkedo

Most SMS apps and messaging platforms already offer basic automations or native integrations. For example, you can trigger a text message after a form submission, a CRM update, or a campaign event. While these built-in features work for simple use cases, they often fall short when businesses need more flexibility, different triggers, or deeper customization.

In real-world operations, companies use a wide range of tools: different CRMs, work OS platforms, form builders, databases, and internal systems. The applications supported by native integrations may not match the software teams actually use. In addition, more advanced workflows, such as multi-step approvals, conditional logic, or cross-system data handling, are usually not possible with standard SMS automations.

This is where Monkedo comes in. Monkedo acts as an automation and integration layer between your SMS app and the rest of your software stack. It allows teams to connect any supported application, define custom triggers and actions, and build end-to-end SMS automations without writing code. With Monkedo, SMS messages become a flexible part of broader business workflows rather than isolated notifications.

Send an SMS to Customers When a Task Is Completed

In this scenario, a task is marked as completed in a CRM or work management system. Monkedo Automation Tool detects the status change and automatically sends a text message to the customer via an SMS app. The message can include task details, completion confirmation, or next steps, creating a timely and consistent customer notification experience without manual follow-up.

Send Document Reminders via SMS Before a Deadline

A form or document collection tool tracks required submissions and due dates. Monkedo Automation Platform monitors the deadline and triggers an SMS reminder if the document has not been submitted by a specific date. This automation helps reduce delays by sending clear text message reminders directly to the recipient’s phone, improving response rates compared to email alone.

Notify Team Members via SMS for Internal Updates

When an important update occurs in a work OS or project management tool, Monkedo sends an SMS notification to relevant team members. This is especially useful for urgent changes, approvals, or incidents where immediate attention is required. SMS notifications ensure the message is delivered even if team members are not actively using the messaging app or chat tool.

Marketing SMS Automation Across Different Tools

Marketing teams often use multiple platforms for lead capture, segmentation, and campaigns. Monkedo No-Code Automation Tool connects marketing tools with SMS apps to trigger text messages based on user actions, list changes, or campaign rules. This allows teams to automate SMS messaging as part of broader marketing workflows while maintaining control over timing, content, and customization.

Partnership and Referral SMS Automation

In partnership-driven workflows, actions such as a new referral, deal status change, or partner submission can trigger an SMS notification. Monkedo No-Code Automation Platform connects partner portals, CRM systems, or databases with SMS apps to send timely updates to partners or internal teams. This automation improves communication, reduces manual coordination, and keeps all parties informed throughout the partnership lifecycle.

Find the Best Texting App

Finding the best SMS app is no longer just about sending text messages. In 2025, the real value of a texting app comes from how well it integrates with your existing tools and how easily it can be automated to support daily operations. Whether you are sending customer notifications, internal alerts, reminders, or marketing messages, SMS works best when it is connected to the systems that already run your business.

Each SMS app covered in this article (NetGSM, Textlocal, Twilio, MessageBird, JustCall, Aircall, and Pushbullet) serves a different purpose. The best SMS app for your business depends on where you operate, who you communicate with, and how complex your workflows are. Some teams prioritize local delivery, others need global reach, while some focus on sales, support, or internal communication.

What turns any of these tools into the best SMS app for real-world use is automation. By using Monkedo, businesses can go beyond limited native integrations and build custom SMS automations that match their exact processes. Instead of adapting your workflows to fit a messaging tool, Monkedo allows your SMS app to adapt to your workflows.

If you are looking to move beyond manual texting and disconnected notifications, combining the right SMS app with Monkedo is the most effective way to build reliable, scalable, and customizable SMS messaging automation.
