Thinking about adding SMS marketing to your agency’s services? Smart move! Text messaging is one of the fastest and most effective ways to connect with an audience. But here’s the thing: not all SMS providers are created equal. Some are modern and powerful, while others… well, they’re sending the same generic message to everyone with no way to track results.

Here’s how to pick the right partner for your agency (and avoid a few headaches along the way).

Your team is running multiple campaigns and juggling several clients at once. The right SMS provider makes that simple by letting you manage all campaigns in one dashboard. No messy log-ins, no confusion over which client is sending what. Just clean, organized access that saves time and stress.

Look for providers that offer white-label solutions, allowing you to brand the platform as your own. This means your clients see your agency’s branding throughout their experience, reinforcing your professional relationship and keeping your brand front and center.

Example: Imagine being able to schedule a flash sale for one client, a holiday promotion for another, and a customer reminder for a third all from the same account!

Text marketing has rules. People have to say “yes” before you can send them texts, and they need an easy way to say “stop” if they change their mind. A good SMS provider handles all of this automatically, so you and your clients don’t have to worry about compliance or upsetting customers. Ensure your provider has opt-in, opt-out management, and provides support for registering your phone number properly.

Clients don’t just want to know that messages were sent. They want proof that those messages worked. They want results! Did people click the link? Did sales go up? The best SMS providers give you clear reports so you can show clients exactly how their campaigns are performing.

Beyond initial campaign results, look for providers that help you re-engage subscribers who clicked through follow-up sequences and send reminder messages to those who didn’t open or click. This ensures you’re maximizing every campaign’s potential and getting the most value from your subscriber lists.

It’s the difference between saying, “We sent 1,000 texts” and “We sent 1,000 texts, 200 people clicked the link to buy, and we followed up with the remaining 800 through a targeted reminder sequence.”

Great SMS marketing is about timing and relevance. Automation means texts can be sent automatically based on a trigger–a welcome message right after someone signs up or a birthday coupon sent on their big day. Personalization makes texts feel human, like including a customer’s first name or recommending products based on past purchases.

Your SMS provider should also offer flexible billing options that work with your agency model. Whether you prefer to bill clients directly or have the agency handle all billing to package SMS with other services, the right provider accommodates your business structure. Look for transparent pricing that clearly shows carrier fees, setup costs, and any additional charges–no hidden surprises that complicate your client relationships.

Instead of a generic “Shop our sale,” it could be, “Hi Sarah, your favorite sneakers are back in stock! Grab them before they’re gone!”

Even with the best software, questions come up. You want an SMS provider with quick, helpful support that treats you like a partner, not just another number in the queue. The right team will guide you through setup, share best practices, and help your agency (and your clients) succeed.

Look for providers offering white-glove onboarding. Personalized setup assistance that gets your agency running smoothly from day one. The best providers also assign you a dedicated account manager who understands your business and offers live chat support for immediate assistance when you need it most.

Choosing an SMS provider doesn’t have to feel overwhelming. Look for one that’s easy to manage, keeps you compliant, proves real results, offers smart tools like automation and personalization, and backs it all up with friendly, reliable support.
