Every reminder counts: salonMonster runs revenue-critical messaging on Telnyx

A couple of no-shows in a single day can cost an independent stylist hundreds of dollars. Stretch that across a year and the hole grows to tens of thousands. That arithmetic is why salonMonster, a digital toolkit that builds the whole back office for independent stylists, salons, and other beauty professionals, treats a booking reminder as a piece of revenue rather than a courtesy text.

"Making sure those are delivered is so crucial for us," said Stephen Parslow, Co-founder and CEO of salonMonster. "It really changes their revenue over the year. A couple of no-shows in the day can cost them hundreds of dollars. You multiply that over a year and it ends up being tens of thousands of dollars."

Booking reminders and confirmations run on the Telnyx SMS API, and Parslow described Telnyx as instrumental in building out that messaging layer.

Onboarding with an engineer, not a manual

The relationship started with a person rather than a portal. "Telnyx was very good at setting us up with an engineer so that we were able to get onboarded onto the Telnyx system and understand what's involved in the integration process," said Parslow, "as opposed to us trying to feel our way around the system."

From there, salonMonster made an architectural choice that has protected the business ever since: appointment reminders live in their own channel, walled off from everything else. "Being able to separate out our appointment reminders into one channel and keep that separate from marketing messaging has been really helpful," said Parslow. Trial signups occasionally turn out to be bad actors, and a number that gets blocked for misuse can never be allowed to drag the reminder system down with it. "We really need to make sure that doesn't take down our reminder systems."

When filtering happens, Telnyx chases the carriers

Parslow was careful to draw a line between platform problems and carrier problems, because in several years on Telnyx he has only encountered the latter. "We haven't had any issues with it over the last few years that we've been with it," he said. "When we have encountered some deliverability issues, the Telnyx team has been good at following up with the carriers on our behalf. They haven't been Telnyx issues itself. It's been issues with carriers doing unnecessary filtering."

The detection side belongs to salonMonster, and the resolution side belongs to Telnyx. When a smaller carrier starts filtering traffic it shouldn't, the team spots it through the API and webhook data, then hands it over. "We're able to identify that through the API and webhook infrastructure and then pass that to Telnyx to resolve," said Parslow.

A number of their own for every salon

Messaging was the beginning, not the destination. "One of the reasons we moved to Telnyx was to give us the flexibility to give each of our customers their own number," said Parslow. "Part of that was infrastructure. Part of that was Telnyx made it within range price-wise for us to be able to do that."

Dedicated phone numbers per salon open a bigger door: moving each salon's phone system into the salonMonster app itself. "We're not quite there yet, but it's an area we're excited to be building into," he said. "Moving past the messaging side of things and into actually being able to do voice communications for them. And now that we're in the AI era, being able to do more text-based booking solutions or voice-based booking solutions, it's really easy to integrate with that."

One API for a continent of carriers

Building from Canada for all of North America means facing a sprawl of carriers, each with its own compliance quirks. Parslow's view is that this is exactly the layer a product company should not build itself. "There would be a lot of compliance and a lot of integration challenges around that, which Telnyx handles for us," he said. "We don't have to worry about dealing with each different carrier. We can just interact with the API, get our webhooks set up, and get the data back that we need."

The same pattern carried salonMonster beyond the continent. A smaller share of its messaging is international, and Telnyx set it up market by market. "We've been able to work with Telnyx to set that up for countries like Australia or the UK," said Parslow. "They've been able to help us deal with our compliance in those countries."

Well priced and robust

The recommendation Parslow offers other companies comes down to the two qualities a revenue-critical system demands. "We found Telnyx to be a really well-priced solution for what it offers, as well as it's been really robust for us," he said. For a platform where every undelivered reminder has a dollar figure attached, robust is the feature that matters most.
