Twilio gives you raw SMS infrastructure that you have to build into a working product yourself — InfinitySMS gives real estate agents and teams the same sending power with bulk messaging, two-way inbox, merge tags, opt-out handling, throttling, and 10DLC compliance already built in, for a flat $99/mo + $0.02 per message.
Why are real estate professionals searching for a Twilio alternative?
Twilio is genuinely impressive infrastructure. It powers SMS for thousands of apps and moves messages reliably at scale. The problem is that it's an API — a set of building blocks for developers. When a real estate agent, investor, or brokerage signs up for Twilio, they're not getting a texting platform. They're getting raw materials and a bill that requires a spreadsheet to decode.
To send a compliant bulk SMS to a lead list with Twilio, you'd need to build or buy: a web application, a contacts database, opt-out tracking (legally required), message throttling, a two-way inbox for replies, merge tag logic for personalization, and complete your own 10DLC brand and campaign registration. That's a software project, not a marketing tool.
InfinitySMS was built specifically for real estate SMS marketing — for agents, teams, brokers, and investors who want to send messages, not write code. Every feature Twilio requires you to build is already there.

What does 10DLC compliance actually mean, and why does it matter?
10DLC (10-digit long code) is the US carrier framework that governs application-to-person (A2P) text messaging from standard phone numbers. Since 2023, any business sending bulk SMS in the US must register a brand and a messaging campaign with The Campaign Registry. Unregistered traffic gets filtered or blocked by carriers — your messages simply don't arrive.
With Twilio, you're responsible for completing that registration yourself. The process involves submitting your business details, EIN, use case, message samples, and opt-in language — then waiting for approval. Mistakes or rejections are common for first-timers. With InfinitySMS, 10DLC registration is handled for you as part of the onboarding process. You don't file paperwork. You just start texting.
How does the pricing actually compare at real sending volumes?
Twilio's pricing is not simple. The per-message rate for outbound SMS in the US is publicly listed, but your total bill depends on the number type you use, inbound messages, phone number rental fees, and whether you're using any add-ons. There's no single number you can plan around.
InfinitySMS charges $99/mo flat plus $0.02 per message sent. No per-seat fees. No credit expiry. One number to put in your budget.
| Monthly sends | InfinitySMS total cost | What Twilio requires first |
|---|---|---|
| 500 messages | $109/mo ($99 + $10) | A developer, an app, and 10DLC registration |
| 1,000 messages | $119/mo ($99 + $20) | A developer, an app, and 10DLC registration |
| 2,500 messages | $149/mo ($99 + $50) | A developer, an app, and 10DLC registration |
| 5,000 messages | $199/mo ($99 + $100) | A developer, an app, and 10DLC registration |
| 10,000 messages | $299/mo ($99 + $200) | A developer, an app, and 10DLC registration |
The comparison above isn't really about per-message cost. It's about what you have to build and pay for before you can send a single compliant message with Twilio vs. InfinitySMS. If you already have a developer-built Twilio integration running, the math looks different. If you don't, InfinitySMS is the faster and more predictable path.
Who should actually use Twilio?
Twilio is the right choice if you have a development team building a custom CRM, a proptech product, or an internal tool that needs SMS as one component. It's powerful, flexible, and well-documented. If you need to embed SMS into software you're already building, Twilio is a reasonable foundation.
It's not the right choice if you're an agent, team, brokerage, or investor who wants to text leads, respond to inquiries, and run drip campaigns — and you need that working this week, not after a software development engagement.
Who should use InfinitySMS?
- Real estate agents who want to text leads from a list without touching code
- Teams and brokerages that need a shared two-way inbox for lead replies
- Investors running high-volume outreach to motivated seller lists
- Brokers who want predictable SMS costs without per-seat pricing as the team grows
- Anyone who has tried to set up Twilio and hit a wall at 10DLC registration
What features does InfinitySMS include?
- Bulk SMS — send to contact lists in a few clicks
- Two-way inbox — see and respond to replies, no separate app required
- Merge tags — personalize messages with contact name, address, or any field
- Opt-out handling — STOP replies are processed automatically, keeping you compliant
- Message throttling — sends are paced to avoid carrier filtering
- 10DLC registration — handled during onboarding, not your problem to manage
- Flat pricing — $99/mo + $0.02/send, no per-seat fees, no credit expiry
Can I switch from Twilio to InfinitySMS without losing my contacts?
Yes. InfinitySMS lets you import contact lists, so you can bring your existing leads over. You won't need to rebuild your list from scratch.
Does InfinitySMS handle TCPA opt-out compliance automatically?
Yes. When a contact replies STOP, they are automatically removed from future sends. You don't need to build or manage that logic yourself — it's part of the platform.
Is InfinitySMS really $99/mo flat, or are there hidden fees?
The pricing is $99/mo plus $0.02 per message sent. There are no per-seat fees and no credit expiry. 10DLC registration is handled as part of onboarding. That's the full picture.
