Keep Customers Informed
with Automated SMS
Send order confirmations, shipping updates, appointment reminders, and alerts to customers in 190+ countries. SMS has 98% open rates — your notifications actually get read.
What is an SMS Notification?
An SMS notification is an automated text message sent directly to a customer's phone in response to a specific event or action. Unlike emails that sit in inboxes, SMS messages appear instantly on the lock screen and are typically read within 3 minutes.
SMS notifications bypass spam filters, don't require app installation, and work on every phone globally. They're used for time-sensitive alerts: order confirmations, shipping updates, appointment reminders, payment confirmations, security alerts, and operational notifications. With a 98% open rate and no reliance on internet connectivity, SMS is the most reliable way to ensure your message gets through.

Email is great for newsletters. Push requires an app install. SMS is the universal fallback that just works.
Instant Delivery
Messages arrive within seconds and are read within 3 minutes on average. No spam folders, no notification fatigue filters.
No App Required
Reach every customer regardless of whether they've installed your app or enabled push notifications. Works on every phone worldwide.
Proven ROI
Order notification SMS reduces support contact rate by 40-60%. Appointment reminders cut no-shows by up to 40%. The cost pays itself back quickly.
SMS Notifications vs Push Notifications
Both channels have their place. Here's how they compare.
| Feature | SMS | Push Notifications |
|---|---|---|
| Requires App Installation | ❌ No | ✅ Yes |
| Delivery Rate | 99.9% | 85-95% |
| Open Rate | 98% | 30-50% |
| Average Read Time | 3 minutes | 30 seconds |
| Internet Required | ❌ No (works on 2G) | ✅ Yes |
| Rich Media Support | Limited (text only) | ✅ Yes (images, buttons) |
| Cost | €0.02–0.10 | Lower per message |
| Best For | Urgent, guaranteed-read alerts | In-app engagement |
TL;DR: Use SMS for notifications that must be seen (orders, payments, security). Use push for engagement and rich interactions. Many successful businesses use both.
When to Send SMS Notifications
Timing and relevance are everything. Know when SMS is the right choice.
Send SMS When:
- • Order placed or confirmed — instant confirmation reduces "did it go through?" support tickets
- • Payment failed — customer needs to update card details immediately
- • Shipping update — delivery time, location changes, or out-for-delivery alerts
- • Appointment reminder — 24 hours and 1 hour before (proven to reduce no-shows by 40%)
- • Account security alert — new login, password change, suspicious activity
- • Password reset or 2FA — authentication codes must be delivered instantly
- • Time-sensitive offer — flash sale or limited-time code
- • Urgent operational alert — SLA breach, infrastructure issue, or downtime notification
Avoid SMS When:
- • Newsletter or bulk marketing — use email (lower cost, higher tolerance for volume)
- • Non-urgent information — general updates that don't need immediate action
- • Promotional content without value — pure ads annoy customers and increase churn
- • Messages during off-hours — respect time zones; schedule for business hours
- • Redundant notifications — don't repeat the same alert twice in a row
- • Customer hasn't opted in — legal requirement in most countries (GDPR, TCPA, etc.)
- • Rich media is essential — if you need images or buttons, push or email works better
- • Conversation required — complex customer service needs live chat or email threads
