10 Best RCS Bulk Message Sender Platforms in 2025

In this hyper-connected world, having a constant channel to stay connected with your customers is a must. Long gone are the days when you can just send a couple of emails and get conversions. 

These days, you can constantly reach out to customers, remind them of your existence, and nurture them throughout the stages of the sales pipeline. That being said, you have to run marketing campaigns to reach out to both new and old customers. 

However, before you start sending bulk messages, you need to pick a channel for your choice. RCS or Rich Communication Service, is an emerging channel with modern communication features that rivals that of WhatsApp and Messenger. 

Having said that, the ability to send messages at scale can let you engage customers more efficiently. These platforms you choose to run the RCS marketing campaigns can greatly enhance the outreach experience.

So, in this blog post, I will explore the 10 best RCS bulk message sender platforms, evaluating their features and benefits, and how they can help you reshape your mobile marketing efforts. Let’s get into it starting with Zixflow. 

Zixflow

Zixflow is a Google-partnered RCS solution, that is both intuitive to use and is backed with powerful infrastructure to let you send thousands of messages at once. 

With its RCS Messaging Platform, you can set up dynamic marketing campaigns without requiring any coding knowledge. The campaign builder of Zixflow offers a no-code environment to design your bulk messaging campaigns effortlessly. 

Furthermore, using the built-in CRM of Zixflow, you can manage customer opt-ins. For example, you can create a separate column, where you can mark opt-out contacts within the CRM, and every time you run an RCS campaign, the system will automatically skip the opt-out contacts from the list. 

On top of that, since RCS requires you to engage contacts via a message template, Zixflow comes with a template builder to make it easy for you to design personalized messages. You can craft three types of messages:

‍

• Basic text
• Rich card 
• Carousel

‍

Based on your outreach strategy, you can create suitable templates and save them in the system for later use. 

Pricing

Zixflow offers three straightforward pricing plans that go from $39/month to $139/month. Each of these plans supports up to 3 users and you can try out the platform with a free 7-day trial. 

Why choose Zixflow?

Zixflow is a great platform for businesses of all sizes. It is a completely code-free solution that is easy to navigate and use. Plus, you can run multichannel communication across channels like WhatsApp, SMS, and email, on top of RCS. Pair that with the robust automation functionality and a centralized inbox, and you get a complete workplace suite for all your business needs. 

Twilio

Twilio has long been a leader in the world of cloud communications. With the introduction of RCS support, it has become a preferred choice for businesses that want to take advantage of RCS marketing and send messages at scale. The platform enables you to send rich, personalized messages to customers globally while maintaining high levels of automation and security.

Twilio is an API-based solution. This means you need to integrate these APIs with your existing systems or configure them according to your needs. Although these APIs are powerful and allow for greater customizability, they require a decent level of technical expertise to work your way around them. 

Moreover, the platform is highly customizable, where you can set up bulk RCS initiatives to engage your audience with tailored messages to drive interaction. With personalized images, product carousels, and suggested buttons, you can improve the performance of your efforts to get better results. 

Pricing

Pricing for Twilio’s RCS bulk messaging service varies based on factors like message volume, geographical location, and customization. However, Twilio’s pay-as-you-go pricing model allows you to scale without incurring hefty upfront costs. Get in touch with its sales team for more information about pricing.

Why choose Twilio?

Twilio is an excellent choice for businesses seeking a scalable solution with global reach and robust security features. However, to fully utilize the capabilities of the platform, you will either need a good idea about technical stuff or hire a developer to set it up for you.
