Top 10 SMS Gateway Features to Look For in a Service Provider

437 Views

An SMS gateway service enables businesses to send and receive text messages at scale for notifications, alerts, marketing campaigns and more. As SMS continues growing as a communication channel, choosing the right gateway platform is key to unlocking its full potential.

When evaluating sms gateway service providers, here are the top 10 essential features to look for:

1.  Reliable Delivery

The most important factor for an SMS gateway is reliably delivering text messages to recipients all over the world. When choosing an SMS gateway provider, it is critical to ensure they have a high delivery rate for messages sent to major countries and cellular networks. The provider’s ability to reliably deliver texts depends largely on how deeply integrated their system is with the direct infrastructure of individual carriers.

Providers have vastly different track records for successfully transmitting texts and seeing them received by users. It is important to examine recent delivery performance metrics to understand how reliably a given provider can deliver versus others on the market. Having direct connections established with cellular networks worldwide is key, as it removes unreliable middlemen from the transmission process and helps messages reach their destination. Minimizing the number of intermediaries that a message passes through reduces the chances of failure at each point.

Local infrastructure ownership by the SMS gateway provider also helps boost deliverability. Rather than relying on third-party networks in different locations, owning their own systems worldwide means the provider has more control over transmission and can quickly identify and address any issues that arise. This leads to fewer lost or undelivered texts and a more seamless experience for users. Reliable delivery is the core function of an SMS gateway, so these factors are critical to evaluate between potential providers.

2. Scalability

Scalability refers to a system’s ability to handle increasing volumes of work or demand. For SMS services, there can be sudden spikes in traffic that drive more texts being sent through the platform. This could occur during promotions where companies are offering deals or discounts, causing many customers to message about the offer. It could also happen if there are outages at other telecom providers, forcing more traffic onto the SMS platform.

It is important for SMS infrastructure to be able to automatically scale up in response to traffic spikes to ensure high uptime and performance even when at peak loads. Companies should ask their SMS partners about the largest traffic increases they have successfully supported in the past without issues. They should also inquire about the redundancy mechanisms in place, such as multiple data centers, that allow the platform to continue operating smoothly even if one component fails during times of high volume.

3. Flexible APIs

Developer friendly SMS APIs allow seamlessly integrating messaging into business apps and workflows. Look for diverse code libraries, detailed documentation and sample code to accelerate builds.

Beyond basic API capabilities, assess how easy providers make adoption through SDKs reducing dev time, integrated UI components, webhooks enabling real-time SMS triggers from systems and tools simplifying debugging. This developer experience ensures faster time-to-market.

4. Compliance Tools

Stay compliant across TCPA, GDPR, CASL and other regulations with consent tools, spam detection, customizable sender IDs and logs helping track messaging compliance.

Global policy shifts around consumer messaging require ongoing vigilance. Seek SMS vendors with processes helping ease compliance in regulated territories through double opt-in widgets, geo-targeting of messages, and tools simplifying reporting across norms. As guidelines evolve, being able to demonstrate adherence grows complex without support.

5. Rules Engine

Visually build advanced SMS automations like appointment reminders, alerts, keyword triggers and two-way conversations without complex coding.

Check whether rule builders allow easily setting up use cases like scheduled promotions, personalizing message flows using variables and contact attributes, routing inbound messages to different staff as needed and chaining career pathways using visual workflow. Pre-built templates can further simplify getting started for common scenarios.

6. Chatbot Capabilities 

Engage customers via conversational SMS-based chatbots using menus, quick replies and variables for personalized experiences.

Text-based chatbots streamline answering common questions, providing assistance or even driving transactions over SMS reliably. Evaluate tools to build and optimize chatbots without needing extensive technical knowledge. Having the option later allows scaling intelligent automation.

7. Number Provisioning

Buy local or toll-free numbers to enable customers to engage via two-way SMS easily without shortcodes. Long codes build familiarity with customers.

See whether service providers enable bringing custom phone numbers onto their platform or provide native long codes. Two-way interactivity depends on enabling customers to respond conveniently. vanity numbers are simpler recalling for consumers than short codes. They feel more responsive lifting engagement.

8. Message Tracking

Individual message tracking with statuses like ‘delivered’, ‘read’ etc. helps monitor campaign effectiveness and troubleshoot issues faster.

Check for real-time visibility into message delivery lifecycle down to individual IDs. This helps identify delays due to carrier rejections, spam filters or configuration issues quickly. With data on opens, link clicks etc. analyzing effectiveness also improves.

9. Analytics Dashboard

In-depth reporting around deliverability, response times, clicks, opt-outs etc. provides insight to optimize SMS approach. Segment contacts and track KPIs over time.

Robust analytics surfaces trends around core metrics allowing continuous SMS optimization. Custom reports bring visibility over what matters most per use case, while scheduled report automation saves management time. Can tools provide sufficient flexibility tailoring analytics views?

10.  Omnichannel Support

With capabilities like MMS, RCS, push, email etc. in one platform alongside SMS, you can coordinate broader customer engagement.

Evaluate the breadth of unified channels available beyond SMS for coordinating contextual messaging across media from one interface. Support for next-gen channels like RCS helps futureproof investment, while MMS and email build atop SMS. Having integrated customer profiles and segments amplifies orchestration.

Conclusion

Evaluating technical capabilities, deliverability, developer experience, security and compliance help find well-rounded sms gateway service to drive messaging growth. Keeping these top 10 features in mind while selection sets up success. Remember to assess domestic and international performance across use cases before finalizing providers.
