What Sent Solves

Sent isn't for every app, but once messaging grows beyond simple SMS notifications, the cracks start to show. At scale, you hit problems that adding another provider API can't fix. Those are infrastructure problems, and they are exactly what Sent is built to solve.

Where Messaging Gets Hard

Messaging might seem like a simple problem at first, but it quickly becomes complex as you scale.

Deliverability Guarantees

Some messages cannot fail. If they don't land, you break user trust or business operations:

Authentication & Security

Login codes, 2FA, fraud alerts, password resets. If delivery fails, users are locked out or left vulnerable. These need speed, redundancy, and reliability that a single provider can't guarantee.

Transactional Confirmations

Order confirmations, payments, shipping updates, account changes. Users depend on them to know something important happened, which is why tracking message status end to end matters as much as sending.

Critical Alerts

Outages, security incidents, or time-sensitive events. Sometimes you need to send on multiple channels at once to make sure users actually see them.

Multichannel Needs

As your user base diversifies, "just send SMS" stops working quickly:

Geography

SMS dominates in the U.S., WhatsApp in Latin America, and that mix keeps shifting.

Demographics

Younger users may lean on WhatsApp or iMessage. Older users expect SMS. Different devices and habits mean no single channel covers everyone.

Device Capabilities

Some users have flip phones. Others expect interactive, media-rich messages. You need to adapt per device, not pick one lowest-common-denominator channel.

Scaling Up

High-volume messaging introduces problems you can't solve with quick fixes:

Cost Pressure

At scale, every cent per message matters. Static routing wastes money. Dynamic routing based on price and delivery performance saves it.

Reliability

Depending on one provider is a single point of failure. Intelligent multi-provider failover is a must.

Compliance

Opt-outs, regulations, content checks. At low volume you can handle this manually; at high volume you need automation, from opt-out handling to regulatory compliance, or you lose time and risk fines.

When Sent Makes a Difference

What Sent provides:

Multi-channel delivery: One API for every supported channel: SMS, WhatsApp, RCS, and future ones. No juggling providers.
Deliverability guarantees: If a missed delivery is a business issue, you need fallback and redundancy.
Global reach at scale: Regional optimization and compliance built in, instead of cobbling together country-by-country setups.
Engineering focus: Keep your team focused on your product, not fighting messaging edge cases.
RCS rich messaging: Reach Android users with branded, interactive messages without building a separate integration. Automatic fallback to SMS means no recipient is left out.

RCS Use Cases

RCS unlocks richer interactions for Android users that plain SMS cannot match.

Interactive Campaigns

Suggestion chips generated from template buttons let you gather quick feedback ("Rate your experience: Good / Poor") or guide users through a flow ("Track Order" / "Contact Support") directly in the message thread.

Branded Transactional Messages

Delivery confirmations and appointment reminders sent with your company logo and verified checkmark build trust compared to an unknown short code number.

Rich cards and scrollable product carousels are part of the RCS standard but are not yet available through Sent. RCS messages currently render as text plus suggestion chips.

Who Benefits Most

B2C SaaS

Apps where messaging drives engagement, security, or operations.

Financial Services

Banking, payments, and investment platforms where trust depends on reliable, compliant delivery.

E-commerce & Marketplaces

Order/shipping notifications and customer service updates at scale.

Developer Platforms & ISVs

Platforms embedding messaging into their own products without wanting to manage provider sprawl.

Emerging Segments

AI-driven systems that generate huge volumes of context-sensitive messages.
IoT and connected devices that need guaranteed delivery across varying endpoints.
Logistics and supply chain platforms coordinating fast-moving operations.

Sent fits best when messaging is core to your business, multi-channel, or at scale. For the cases where a direct provider integration or an in-house build serves you better, Compare Your Options works through the full decision. If your scenario already matches the ones above, the quickstart takes you from account setup to your first delivered message.
