How to choose an SMS provider

Here are the key factors you should consider when choosing an SMS provider.

Deliverability & performance

You’ll want to look for a business SMS provider with a proven track record of handling high text message volumes. You might want to consider a provider that uses a cloud-based infrastructure or is well-known in the CPaaS space.

If a provider isn’t forthcoming about their SMS delivery rates, it could indicate messages may not be consistently reaching their recipients. This would be a good reason to discount them from your list of candidates.

Scalability

You’ll want to ensure that you pick a provider that can handle your current volume of text messages and scale as your business grows.

If a provider claims to be able to accommodate your needs, but this comes at the cost of performance, they won’t be able to grow with you and likely aren’t a worthwhile investment.

Security

Meeting regulations like EU’s GDPR is a must for any SMS service provider. Their security should be up to industry standards, as they will handle sensitive customer information and data.

Encryption, two-factor authentication, and secure data storage are features to watch for. A history of data breaches might indicate that their security is not up to scratch.

Compliance

When engaging your global audience over SMS, you must ensure that your content complies with local SMS laws. Look for a provider that knows SMS compliance – so that you don’t have to.

SMS providers that operate internationally through locally established offices will know the rules and help you and your business stay compliant.

Coverage & connections

If your customer base is global, it’s a good idea to opt for an SMS provider that offers broad coverage across multiple countries. You might want to see examples of the local carriers that they are partnered with. The more mobile network operators in different countries, the wider reach you can expect to have.

Look for a provider that lists how many direct connections they have to operators around the world. This ensures that your business has direct connections to customers, globally.

Routing

Making sure that your business text messages reach their recipients reliably and in good time can also be enhanced with good message routing. Essentially, this refers to how an SMS provider determines the best path for delivering messages from the SMS gateway to your customers’ mobile devices.

Integrations

Your provider should be able to help you integrate a business SMS service into your existing systems. However, some services are bound to be more compatible than others.

You may need to verify with your CRM, marketing automation and customer support software that the SMS platform will work well alongside them. The goal is to have a streamlined workflow, not crosscurrents.

API

If an SMS API sounds ideal, but is difficult to integrate with your existing marketing channels, then is it truly perfect?

Your development team will appreciate all of the supportive resources they can get – if your chosen provider offers lots of options, such as SDKs, docs or support forums, it shows that not only are they keen on you using their services, but they want you to be able to get the most out of them.

Message types & features

Make sure that you understand the types of text messages and levels of message customization on offer from each SMS provider you look into.

You might be interested in a high level of personalization in your customer service, or looking to use advanced SMS service features, like A/B testing, for example, and connect with your audience in an engaging way. Scheduling and delivery tracking features should also be high on your priority list.

Analytics & reporting

One of the main benefits of using SMS for business is the fact that SMS has a much higher open rate than email – but if your provider can’t give you the data to back this up, you might not be able to prove its worth to your stakeholders.

Analytics and reporting capabilities should be a key element for any SMS provider, as it is these insights that will allow you to optimize your SMS campaigns and get the most out of this communication channel.

Customer support

While your preferred method of customer support is an individual preference, it is prudent to opt for an SMS provider that is known for being responsive and helpful, whichever way they choose to communicate.

You’ll want to know that, should an issue arise, you’ll be able to get quick and efficient technical support before there’s a chance for anything to go wrong.

An added bonus is if your SMS provider has offices around the world that can provide support in your local language and be on top of regulations in your area.

Pricing & contracts

It’s always a good idea to shop around to make sure you’re getting the best price, and SMS is no different. You may already have a budget in mind, but be willing to renegotiate for the right provider.

Similarly, contracts and terms and conditions should be thoroughly understood before any commitments are made, as there may be cancellation policies or minimum requirements. Just like with so many things – you get what you pay for.

Check the quality of the connections versus the price. Some providers may have lower prices, and while this may be great for your budget, it could prove disastrous for your delivery rates, delivery times, compliance etc. This is because most low-cost providers don’t have direct connections to operators and instead rely on different aggregators, and this can potentially result in lost traffic.

Trial & testing

It’s always good to see if your SMS provider offers a demo or trial period. This means that you can experience their service firsthand before agreeing to a contract or partnership.

SMS pricing can vary significantly depending on your needs, and you don’t want to end up paying high prices for a service that ultimately doesn’t suit your needs. Offering a demo is a sign that a provider is so confident in their offerings that you’ll have no reason not to commit after trying them for yourself.

Even if you’re only browsing, taking advantage of free trials and demos is a great way to develop a more rounded opinion on what features you need from your provider.

Reputation & reviews

While public perception of a service may not always be 100% accurate, first-hand accounts of services are an invaluable source of information. A provider may tick all of your boxes, but if their reviews consistently mention issues and setbacks then it would be an easy decision to steer clear of their services.

A tried and tested method is to pay attention to middle-of-the-road reviews. These reviews – the three stars, or the five out of tens for example – often show a lot of thought has gone into their evaluation, as they often list both pros and cons of the service they are reviewing.
