best cpaas companies

Communications Platform as a Service companies, or CPaaS companies, are cloud-based platforms that integrate communications capabilities into existing business applications. 

These fully supported platforms facilitate real-time customer interactions for improved marketing, sales, customer service, and more–without developers needing to spend extensive time building individual integrations with communications service providers from scratch. 

Which CPaaS company should you use? This article will review CPaaS benefits, features, and the best Communications Platform as a Service for this year.

What is CPaaS?

CPaaS, or Communications Platform as a Service, is a software category of cloud-based platforms that enables businesses and developers to integrate communications capabilities directly in their applications. 

Users can easily create secure, highly scalable communications solutions that can be integrated with other cloud-based services or existing on-premises systems. These platforms offer features ranging from communications integrations to data intelligence, messaging, speech recognition and synthesis, call conferencing, and more. 

CPaaS removes the burden of manually building communications features from developers, and supports richer customer engagement opportunities that legacy communications solutions cannot provide.  Plus, by freeing up developers’ time, they can focus on building capabilities specifically designed to increase revenue and adoption.

Benefits of using Communications Platforms as a Service

CPaaS is becoming more popular for a reason: it provides incredible communication abilities without time-consuming backend work. Frost & Sullivan found that 74% of IT decision-makers expressed familiarity with CPaaS and programmable communications, citing their invaluable benefits.

Some of the many benefits of implementing CPaaS include:

Better communication

CPaaS offers a range of customer engagement tools that help businesses connect with their customers in real time. As an emerging technology that offers numerous advantages over traditional legacy technologies, CPaaS provides a unified communications experience across multiple providers. This allows businesses to connect with customers on various channels while maintaining the same user experience. 

CPaaS also offers a next-generation customer experience with features like real-time analytics and multi-channel engagement. These advanced capabilities give businesses greater flexibility and control in customer interactions. Plus, CPaaS requires minimal setup and maintenance costs compared to legacy systems, making it ideal for businesses looking to update their communications infrastructure quickly and cost-effectively.

Cost optimization

CPaaS provides organizations with access to cost-effective, secure, and reliable platforms that minimize the costs associated with developing, maintaining, and deploying communications integrations and features in-house.

Instead of a team of developers spending one to two years (or more) creating their own platform, the best CPaaS helps an organization add communications capabilities into their application in just a few sprints.  These platforms also drastically reduce ongoing maintenance, bug resolution, and unanticipated customer requests that will sidetrack your engineering resources for years to come. 

Product and engineering teams at leading brands and fast-growing startups have leveraged CPaaS to rapidly stand up engaging communications features that boost ARR 150%, reduce churn 75% and increase users by 580%.  

Operational efficiency 

CPaaS enables businesses to quickly and easily scale their communication infrastructure up or down as needed, with minimal disruption. This makes it ideal for rapidly growing or changing companies since they can expand their messaging capabilities without the extra cost of hardware and software. CPaaS solutions are incredibly flexible, allowing users to customize their messaging platforms according to their needs. 

CPaaS also offers improved reliability and uptime compared to traditional communication solutions. Businesses don’t have to worry about outages disrupting their operations or poor performance degrading user experience. 

The best CPaaS companies leverage workflow automation to eliminate the need for organizations to build additional quality-of-life features that save customers time and make them more productive. 

Improved customer experience

Using a Communications Platform as a Service allows businesses to add various communication channels to their customer-facing applications. This makes it easier for customers to reach out for support and for customer service teams to resolve queries. 

CPaaS also allows businesses to send personalized SMS or email messages to customers based on their profiles. This helps create a more personalized and engaging customer experience.

CPaaS features to look for

What features should your Communications Platform as a Service include? Let’s take a look.

1). Integrations

Integration options allow CPaaS users to connect their applications with other communications channels, systems, and services. These include everything from email, calendar, and contacts to other business applications like CRMs to external APIs and webhooks.

2). Intelligence

CPaaS has a wide range of features to offer, but one of the most valuable is its intelligence analysis capabilities. The best CPaaS providers can efficiently fuel business intelligence and unlock holistic views of customers by making sense of unstructured communications data.

For example, Nylas offers out-of-the-box analytics such as open rates, reply tracking, and link tracking to help build robust email capabilities quickly and effectively. Real-time scheduling capabilities can provide instant booking based on availability across many calendars and time zones. These advanced features allow businesses to maximize customer engagement, loyalty, and revenue via personalized experiences.

3). Scalability

Scalability allows for increased capacity and performance with minimal effort. This feature is especially beneficial for businesses that may experience heavy and unexpected demand spikes from customers. Companies can quickly scale up their resources to meet the sudden demand without investing in more hardware or personnel.

4). Security & privacy

Prioritizing security and privacy ensures the confidentiality, integrity, and availability of communication and applications, as well as protects user data. A CPaaS should have measures in place to encrypt data in transit and at rest, provide robust access controls, protect data privacy, and undergo regular security audits and testing.

Administrators can create multiple layers of security for their system, including setting user access levels, enforcing password policies, and using two-factor authentication.

5). Ease of use

An easy-to-use CPaaS minimizes the learning curve for new users and increases the adoption and usage of the platform.  Platforms should offer an intuitive user interface, available comprehensive documentation and support resources, automation, and self-service features. 

This helps with the quick deployment of communications applications, reducing time-to-market for organizations looking to bring new services to their customers.
