Standard text message marketing apps aren’t built to handle real volume, compliance requirements, or the coordination needed across multiple departments. 

As your outreach grows, so do the operational gaps that make it hard to maintain professionalism and reliability.

A dedicated mass texting app solves these pain points by giving you a controlled, high-deliverability channel built specifically for scale.

In this article, we will break down the best apps for bulk text messaging and determine which SMS platform improves your communication, even when sending to thousands of customers.

Why Use a Dedicated SMS App for Mass Texting

Mobile phone users prefer fast, direct updates over cluttered inboxes. With the right platform, a single text blast becomes a powerful engine for customer engagement, revenue growth, and operational efficiency.

Faster Communication With Large Audiences

A mass texting app lets you reach big groups instantly without running into carrier restrictions or device limitations. Instead of pushing out mass text messages one at a time or juggling multiple phones, you can send a single update to thousands within seconds.

During time-sensitive situations like upcoming events, urgent alerts, or appointment reminders, these platforms make sure every recipient gets the message.

Higher Open Rates Compared to Email

Email inboxes are crowded and unpredictable. Meanwhile, people check their phones constantly, and SMS text messages rarely go ignored.

This makes SMS marketing one of the most reliable channels for ensuring your audience sees your content. If you regularly send SMS marketing campaigns, even a simple reminder can outperform a full email push. 

Increased Customer Engagement and Conversions

Because texting feels personal, people are far more likely to reply, click, or take action. A dedicated app gives you the marketing tools to personalize messages, segment contacts, and follow up automatically based on behavior.

You'll see a huge difference in sales and repeat engagement by switching from scattered communications to a coordinated texting strategy.

Cost-Effective Marketing for Small and Large Teams

Mass texting delivers powerful results without requiring a huge budget or complex systems. Texts are inexpensive to send, easy to automate, and consistently effective across industries.

Small teams save time with tools that let them schedule messages, launch mass text campaigns, or use built-in SMS templates.

Larger operations benefit from advanced features like unlimited contacts, unlimited users, and custom integrations that cover everything from call forwarding to syncing an email account.

10 Best Mass Texting Apps in 2025

As more organizations move away from disconnected communication tools and toward high-impact SMS strategies, choosing the right platform becomes essential.

The difference between a basic tool and a purpose-built system can influence engagement rates, customer satisfaction, and operational performance.

With that in mind, here are the 10 best mass texting apps, each offering strengths to help you communicate faster and with far greater precision.

1. TextUs

TextUs is an SMS engagement platform designed for real-time, two-way business texting. Unlike one-way blast tools, it combines bulk SMS capabilities with conversational texting for large-scale campaigns.

If you're a recruiter, sales teams, or service organization that need fast, high-touch communication, TextUs helps transition your bulk texts to one-on-one conversations for better lead conversion and sales close rates.

This mass texting service offers a full suite of SMS and marketing automation features built for efficiency. You can send unlimited-size text campaigns to large contact lists, with high throughput and deliverability.

Campaign tools include built-in A/B testing, drip sequence automation, and support for MMS messaging and branded short links to increase engagement. 

It also provides a shared team inbox for two-way messaging, so multiple staff can manage replies and ensure no customer text goes unanswered. 

The system’s user-friendly tools and text templates help teams respond consistently. TextUs supports unlimited custom keywords and integrates with popular CRMs to sync contacts and log SMS conversations in real time. 

TextUs stands out for its focus on performance SMS and business outcomes. The platform’s ease of use is frequently praised, and it becomes an organic extension of existing workflows.

2. MessageMedia

MessageMedia (recently rebranded under Sinch) is a business SMS platform for high-volume messaging and multi-channel capabilities.

It allows you to communicate with customers via SMS notifications, MMS, mobile landing pages, and convert web chats to text through its Chatbox-to-SMS feature.

This SMS software supports mass texting and two-way messaging, so you can instantly send group texts and also handle individual text replies or conversations.

MessageMedia provides a web-based interface for non-technical users and APIs for developers, including the ability to authenticate with an API key. 

It also offers dedicated virtual numbers, long codes, short codes, and toll-free numbers so brands can use a consistent sender ID for recognition.

You can also set up automated SMS triggers and drip campaigns using the platform’s workflow tools. Link tracking and mobile landing pages are built in, so you can include short URLs that lead to rich, trackable microsites.

However, some users stated that it would be challenging for non-technical people to learn all the options available. Others have experienced minor platform quirks, such as needing to refresh to see new replies or occasional login issues.

3. Omnisend

Omnisend is an omnichannel marketing platform tailored for e-commerce brands with built-in mass texting capabilities integrated with its email tools. 

You can send personalized bulk text messages and incorporate them into automated workflows for cart recovery, order confirmations, and more.

The platform provides free credits on certain plans to get started. It offers global reach, supporting texting to potential customers in multiple countries, and provides TCPA-compliant opt-in tools.

You can insert dynamic content into texts for one-to-one personalization, and Omnisend’s automation library makes it easy to launch pre-built SMS flows.

Still, some users report limited analytics depth and advanced reporting options. Teams that rely on detailed reports when reviewing performance across email and SMS find that it hinders campaign analysis.

Since Omnisend is geared heavily toward e-commerce use cases, a few users note it’s less suitable for non-retail contexts. It offers fewer general communication features for a small business that isn’t focused on online retail.

4. Attentive

Attentive is an SMS marketing platform with AI-driven personalization and a focus on mobile messaging. It enables you to deliver 1:1 customer experiences via text messaging and email, using advanced data capture and segmentation.

This messaging app provides a suite of tools for mass texting and two-way SMS interactions. It supports triggered messaging and automation flows that send texts based on customer behaviors.

Attentive can auto-generate high-performing message content and optimize send times and segments for better conversion. 

It also offers advanced audience building and dynamic segmentation, where you can target precise customer groups and leverage predictive AI to personalize messages.

It also supports next-gen messaging with RCS (Rich Communication Services) support, turning texts into interactive, media-rich experiences. It provides compliance safeguards and deliverability infrastructure, including carrier coordination to handle huge volumes.

Cost is the most common drawback mentioned. Attentive’s service can be pricey for smaller brands or large contact lists, given its enterprise orientation. Also, some cite feature gaps or usability issues, such as certain integrations may not be as fully featured or easy to implement.

5. TextMagic

TextMagic is a business texting service that caters to companies of all sizes for mass SMS communications. It offers a user-friendly web platform along with a dedicated mobile app for iOS and Android. 

You can import or build contact lists and then send SMS messages to thousands of recipients with a flexible pay-as-you-go model.

The mobile app is synchronized with the web app, sending push notifications for new messages and allowing team members to respond in real time from their phones.

TextMagic also lets you schedule texts, set up recurring messages, and use templates for efficiency. For larger organizations, it supports managing multiple dedicated numbers to handle texts from several department phone numbers within one app and switch sender IDs as needed.

A common critique is that TextMagic’s interface could be more intuitive and modern. Also, a minority of users have experienced delivery delays or stability issues during certain periods. 

These issues suggest that organizations relying on OTP codes or emergency alerts should monitor performance.

6. Salesmsg

Salesmsg is a business text messaging platform that supports two-way SMS and MMS. Its broadcast feature allows you to personalize outbound messages, schedule sends, and track campaign performance.

Through Workflows 2.0, you can trigger messages based on actions, schedule follow-ups, segment contacts, and integrate external services via Zapier. 

It also has support for international SMS, ringless voicemail, and more granular credit and campaign analytics for higher-volume messaging environments.

On top of that, the platform includes team-friendly features like shared or private inboxes, text-enabled business numbers, and integrations with CRMs.

However, some users report delivery issues or delays in messaging, with replies not showing up immediately or messages not always sending cleanly.

Some users found the mobile app or shared inbox experience a little less polished or slower than desired, especially when used in a fast-moving team environment.

7. SlickText

SlickText is an SMS marketing service that combines mass texting capabilities with list growth tools, automation, and two-way messaging. It supports personalization tags to insert customer names or other info into messages, and has an inbox for two-way texting. 

It provides unlimited SMS keywords and allows custom auto-reply messages for each keyword to confirm opt-in or deliver a coupon. There are also embeddable web signup forms and QR codes that you can use to capture opt-ins on your website or in-store signage.

SlickText also includes segmentation capabilities where you can group contacts by attributes or behavior. Its analytics lets you track delivery rates, opt-in growth over time, click-throughs on links, and measure ROI if you tie in sales data.

It natively integrates with major platforms like Mailchimp, Shopify, HubSpot, and Zapier, allowing data sync and cross-channel coordination. It offers a mobile app so you can run campaigns and respond to texts on the go.

However, SlickText is not as advanced in certain niche features. Some users have wished for built-in survey or polling features. There have been mentions that the platform’s UI can feel a bit outdated or clunky when navigating certain sections.

8. DialMyCalls

DialMyCalls is a mass notification platform that provides mass texting and automated calling capabilities, popular among organizations like schools, nonprofits, businesses, and community groups.

The platform offers a set of features for mass SMS and voice campaigns. For texting, you can create or import curated contact lists and send out a bulk SMS blast to everyone on the list simultaneously.

The DialMyCalls mobile app supports long-code, toll-free, and local phone numbers as senders, giving flexibility in how your messages appear. Other notable features include SMS templates for frequently sent messages or a text poll feature for gathering feedback via text responses.

Finally, the platform provides an API and pre-built integrations, so it can be connected to other systems or applications if needed for automated messaging workflows.

However, in earlier versions, responding to incoming texts wasn’t seamless for some users, who would receive a notification of a reply but had to log into the platform to view or respond.

Also, some found the fee for a dedicated outbound number high, leading them to use a personal number, which caused confusion when people tried to call back.

9. Klaviyo

Klaviyo is a marketing automation platform known for its integration with e-commerce platforms and its email marketing capabilities.

In recent years, Klaviyo has also made a major push into SMS marketing, which allows brands to manage email and text campaigns side by side for a true omnichannel approach.

Klaviyo offers mass promotional texting, automated flows, two-way response handling, and detailed analytics. It has a built-in customer data platform (CDP) that aggregates data from your store, emails, and other sources. It allows you to trigger and segment messages based on that data.

The platform lets you target SMS campaigns to segments using its filtering conditions. These segments update dynamically as customer data changes. You can also insert custom fields into texts and use conditional logic in messages.

However, Klaviyo can still be overwhelming for beginners, especially those new to segmentation or multi-channel automation. 

Some users also report that standard support for lower-tier plans can be slow or not as helpful. You have to rely on the community or documentation for non-urgent issues.

10. Sakari

Sakari is an SMS marketing and business texting platform that offers mass texting and contact management capabilities. You can upload or sync contact lists and segment them.

The platform provides customizable web forms to capture leads’ phone numbers, or it can take forms from other systems via integration. Once contacts are in, you can organize them into lists or use attributes for targeting.

On the campaign side, Sakari enables you to create and send bulk SMS campaigns. You can include short links in messages to measure click-through and source attribution.

It includes two-way texting where you can see incoming messages and reply in real time. The platform supports landline texting and enables texting on a business’s existing landline number.

Some feedback indicates the user interface is not as modern or slick as it could be. Also, if you’re not using one of the major CRMs it supports, you might rely on Zapier, which is an extra step.

While Sakari does offer a monthly plan, some users prefer the flexibility of pay-as-you-go pricing from other providers.

FAQs About the App for Mass Texting

What is the best app to send mass texts?

There’s no one-size-fits-all solution, and it depends on your goals, but TextUs stands out for organizations that want faster, more conversational outreach rather than old-school, one-way blast messaging.

TextUs is widely used in staffing, higher education, sales teams, and service-based industries because it combines mass texting with real-time two-way conversations. This is something many traditional SMS platforms don’t handle as well.

Other well-known choices like SimpleTexting or EZ Texting are solid for marketing-style broadcasts, but TextUs is ideal when engagement matters just as much as volume.

Which app is best for sending bulk messages?

TextUs remains a top pick if you want bulk messages to turn into actual conversations instead of getting lost among other messages your audience receives.

While tools like TextMagic or SlickText handle large-scale broadcasts, TextUs adds contact-level personalization, shared team inboxes, fast follow-ups, and integration with CRM and ATS systems.

How do I text 100 people at once?

Most mass-texting apps allow you to upload a contact list or sync your contacts from your CRM, then send a message to all 100 recipients at once. It works whether your team uses desktop tools or Android apps to manage campaigns.

TextUs makes this process easy through its broadcast feature, which lets you send one message to a group while still receiving individual replies in an organized inbox.

Regardless of the platform, make sure everyone on your list has opted in, then create your message, choose your audience, and send or schedule. Some platforms offer a free trial, so you can test the workflow before committing.

How can I send 1000 texts at once?

The process is much like texting 100 people, only scaled. You need to choose an SMS marketing software that supports high volumes, upload your contact list, draft your message, and select the entire list or a large segment, then schedule or send immediately. 

Many services list their pricing starting from modest volumes up to far higher. Also, be aware of carrier restrictions, spam rules, and sending limits that your provider may impose.

If your campaign relies on richer content, such as sending links, short videos, or attaching audio files, you need to confirm that your SMS provider supports those formats.
