Time-critical sends
Passcodes, alerts, and confirmations on high-priority routes so they arrive in seconds, not minutes.
Communications Cloud
The delivery layer your business actually runs on.
SMS, voice, email, and phone numbers through one set of APIs — routed across multiple carriers, tracked message by message, and reachable in 190+ countries and regions. It's the backbone under every AtomMatrix agent, and it holds up just as well on its own.
What it is
One API for every channel that matters.
Communications Cloud is a CPaaS — a communications platform you reach through APIs instead of signing a stack of separate carrier contracts.
Send a transactional text, place an automated call, deliver a receipt email, or provision a local number — all with the same authentication, the same webhooks, and the same dashboard. We take on the parts that are tedious and easy to get wrong: carrier connections in each market, delivery receipts, opt-out and suppression handling, sender registration where regulators require it, and rerouting the instant a route starts to degrade. You send an API request; we make sure it arrives.

Messaging · SMS
Text that gets delivered and reports back
From a single passcode to a million-message campaign, with the delivery receipts and controls you need to trust the numbers.
Campaigns at volume
Bulk sends with throughput that holds up during peaks, plus scheduling and per-segment tracking.
Inbound & keywords
Receive replies, run keyword flows (STOP, HELP, JOIN), and hand conversations to an agent.
Delivery receipts (DLR)
Per-message status — sent, delivered, failed — so you can retry, reroute, or reconcile against billing.
Sender IDs & numbers
Alphanumeric sender IDs, short codes, and long numbers, chosen by what each market allows.
Opt-out & suppression
Automatic unsubscribe handling and suppression lists so you stay compliant without extra plumbing.
Answered by an agent
Put an AI agent behind a number and inbound texts are understood, acted on, and answered over SMS — automatically, with human handoff when it counts.
Voice & calling
Programmable calls, in and out
Notifications that go out, service lines that come in, and menus that route callers — all as events you can build on.
Voice notifications
Deliver time-sensitive updates by phone and capture the customer's response.
Menus & DTMF
Build interactive menus, collect keypad input, and branch callers to the right place.
Service lines
Answer, route, queue, and record inbound calls with events for every step.
Text-to-speech
Read dynamic content aloud in 90+ languages, or play your own audio.
Call events & recordings
Ringing, answered, completed, and recording events feed workflows and analytics.
Machine detection
Tell a person from a voicemail so outbound campaigns leave the right message.
AI voice agent on the line
Hand a live call to an AI voice agent that listens, reasons, calls your systems mid-call, and transfers to a person when needed.
Email that lands in the inbox
Deliverability is a discipline, not a setting. We handle the authentication, reputation, and hygiene that keep you out of the spam folder.
Receipts & alerts
Order confirmations, statements, and notifications sent the moment they're triggered.
Campaigns & journeys
High-volume sends with templating, segmentation, and per-recipient tracking.
SPF · DKIM · DMARC
Guided domain authentication so mailbox providers trust your sending domain.
Sender reputation
Monitoring and warmup guidance to build and protect your domain's standing.
Bounces & complaints
Hard and soft bounces, complaints, and list hygiene handled automatically.
Open, click & delivery
Engagement events you can act on — and feed straight into analytics.
Replies handled by an agent
Route inbound replies to an AI agent that reads the thread, drafts a grounded answer, and sends it back — escalating anything sensitive.
Verification · OTP
One-time passcodes that actually arrive.
A passcode that shows up 40 seconds late is a login that failed. Verification sends codes over the fastest healthy channel and falls back automatically when one stalls.
SMS and voice codes
Send passcodes by text or read them aloud on a call, from one API.
Automatic fallback
If an SMS route doesn't confirm quickly, switch to voice or another carrier without extra code.
Expiry, retries & rate limits
Set how long a code lives, how many tries are allowed, and how often one number can request codes.
Velocity & fraud controls
Spot abuse patterns and pumping before they hit your bill or your users.
Step-up inside an agent
An AI agent can verify a customer mid-conversation before a sensitive action — the code is read back in the same thread and checked before anything changes.
Numbers · DID
A local presence, wherever you operate
Provision the number types each market supports, and use them for two-way messaging and voice.
Local & national
Numbers that look familiar to your customers and improve answer rates.
Toll-free
Where available, toll-free numbers for support and inbound campaigns.
Messaging & voice
Send and receive on the same number, across SMS and calls.
Fast provisioning
Search, buy, and configure numbers by API, with the registration steps handled.
Number pools
Rotate through pools for high-volume outbound while respecting local rules.
Market by market
Availability and number types differ by country — we confirm what you can use where.
Global routing
The reliability isn't luck. It's the routing.
Delivery rates hold up because traffic is never tied to a single carrier. Routes are chosen by quality and live health, and rerouted the moment one starts to slip.
Ask about your markets →Multiple carriers per market
Every destination has more than one path, so no single provider is a single point of failure.
Quality- and delivery-aware
Routing weighs delivery receipts and latency, not just price, and shifts away from routes that degrade.
Automatic failover
A failed or slow send retries on a healthy route in real time — before it becomes your problem.
Throughput for peaks
Reserve capacity ahead of a launch or seasonal spike so nothing gets throttled at the worst moment.
Availability & compliance
The fine print, up front
What varies by market. Channel availability, sender registration, number types, throughput limits, and content rules differ from country to country and by use case. Some markets require sender ID or business registration before you can send. We confirm what's possible in your specific regions during onboarding, handle the registrations we can on your behalf, and are direct about anything we can't. Data can be handled in-region where finance and education requirements call for it.
