SMS is an essential communication channel thanks to its reliability, versatility, delivery speed, global reach and cost-effectiveness. It's also one of the best mediums for getting your message seen; according to research and consulting firm Gartner, text messages achieve open rates as high as 98%.

For these reasons, it makes good sense to leverage SMS for a holistic marketing approach. However, to unlock the power of SMS, you'll likely need assistance from an SMS agency. Keep reading to discover why you need an SMS marketing agency and six providers to check out when you're ready to start.

What is an SMS marketing agency?

An SMS marketing agency can help you design and execute marketing and communication activities via the SMS (short message service) communication channel.

SMS marketing primarily relates to sending promotional text messages, such as special offers, customer loyalty campaigns, product launches and abandoned cart reminders. But it can also include conversational and transactional messages – the former being back-and-forth chats and the latter including business-critical communications like order confirmations, delivery updates and 2FA PIN codes.

SMS marketing is often part of a larger suite of services offered by digital marketing agencies. Some provide individual solutions like SMS API testing and compatibility, while others focus on content creation or auditing and assessment. And some supply the complete package, helping you manage all aspects of your SMS marketing campaigns.

Why you need an SMS advertising agency

SMS delivers everything a strong communication channel should – impressive open rates and great accessibility (every mobile phone has a built-in SMS app). It's also highly reliable, with messages transmitted over cell networks, not WiFi. You probably already use SMS and may wonder whether you can send business texts yourself from your mobile phone. Well, that would be ineffective. Because only an SMS agency can help you with the following:

  • Campaign management – an SMS advertising agency gives you a platform where you can manage multiple SMS campaigns side-by-side, even if you're sending to hundreds or thousands of recipients. This would be virtually impossible to do from your own mobile phone. An agency can also help ensure you're not violating SMS marketing laws and make it easy to manage subscriber opt-ins and opt-outs.

  • Saves time and effort – you can quickly compose a text and send it to your entire subscriber base or specific groups over a single connection, as SMS agencies have agreements with multiple operators worldwide.

  • Masters in SMS marketing – such agencies live and breathe text marketing and know what works and what doesn't. They can advise on creating campaigns that resonate with your audience, including how to write impactful SMS copy, the best times to send messages and how to boost SMS signups.

  • Message customization – the top SMS platforms offer bulk messaging, where you can send a single text to a vast audience and personalize it so the recipient feels like they're getting a one-to-one text from your business.

  • Built-in tools – tracking and improving SMS campaigns is simple with an agency's analytics and educational resources.

  • Access to industry insights – SMS marketing agencies must be at the forefront of business messaging, so when rules, regulations and marketing trends change, you'll be among the first to know.

How to find the right SMS advertising agency for your business

Take into account your specific requirements when exploring SMS marketing agencies. Your budget is an essential factor when comparing pricing plans, but also consider the following:

  • What kind of SMS campaigns do you need to run? For full-scale marketing, you might need help with content creation and automation, so check if your preferred agency offers this.

  • Coverage – what regions does the agency serve? Can they cover all your existing and potential customers' locations?

  • SMS compliance – do they comply with local and international SMS rules and regulations? What measures are in place to ensure no messaging or marketing laws will be broken?

  • Case studies and testimonials – always check the agency's track record with previous or current clients to learn about their experience and expertise.

IMPORTANT! Check the SMS marketing agency is using the right routing service at their backend. For example, Messente is an SMS API provider with partnerships with over 800 mobile networks and hubs – giving you global coverage, optimized routes and high delivery rates.

Choosing the right SMS marketing agency for you

SMS offers you a powerful way of connecting with customers and other stakeholders. It's a direct, efficient, fast and affordable channel for short promotional, transactional and conversational messages. But you can't utilize SMS for business messaging effectively by yourself – you'll need to enlist an SMS marketing agency.

SMS agencies vary in terms of services. Some are specialist SMS platforms, like Messente, with APIs and access to network carriers. We give you all the tools you need to create and manage your own text message campaigns successfully – while we take care of message routing and delivery. You just pay for the texts you send.

The wider service digital marketing agencies handle the creation and execution of your SMS campaigns on your behalf, often alongside other marketing channels, in exchange for a monthly fee plus the cost of sending text messages.

Which SMS agency you choose depends on your budget and specific requirements – the type of texts you want to send, the locations you're sending to and whether you wish to manage your campaigns yourself.
