What it is
What is bulk SMS?
Bulk SMS are text messages a company sends to many recipients at once from a platform, to notify, remind, verify or promote. Unlike a personal SMS, they are sent from a business sender , personalized with each customer’s data, and every message returns a delivery report.
In Mexico, 84.6% of people aged six and over use a mobile phone, according to INEGI’s ENDUTIH 2025. SMS reaches every one of those phones with no app, no data plan and no permissions, which is why it remains the most direct channel for messages customers need to see.
How it works
Send your bulk SMS in 3 steps from the platform
- Upload your contacts from an Excel or CSV file, or connect your system via API. See how to send bulk SMS from Excel.
- Write and personalize the message with variables such as name, date or amount. The counter shows how many segments will be billed before you send.
- Send or schedule the campaign and track in real time how many messages were delivered, how many failed and why.
Platform
Everything the platform includes
Encoding of your choice
You choose GSM7 or UCS-2. With GSM7, unsupported characters are replaced automatically so you don’t pay for extra segments.
Validation of every number
Every number is checked against Mexico’s National Numbering Plan to know whether it is a landline or mobile before sending, so you don’t spend on messages that cannot arrive.
Your brand as the sender
Alphanumeric sender IDs, short codes and long numbers, so customers recognize your company from the notification.
Real-time reports
Delivery status for every message in the panel and via webhooks, at no additional cost.
Tracking links
Know who clicked in each campaign without changing the domain the customer sees.
Flash and two-way SMS
Messages that appear directly on screen for urgent matters, and customer replies to confirm or survey.
Blacklists
Opt-outs and failing numbers are automatically excluded from future sends.
API with sandbox and encryption
Integrate from your ERP, CRM or app with the SMS API, test without sending real messages and encrypt sensitive content.
Specialized support
Priority 24/7 support and custom development when your operation requires it.

Notices and campaigns: each with its own rules
A payment notice, an order confirmation or an access code are transactionalmessages: the customer expects them. A promotion is advertising and requires prior consent. We separate both types of traffic so a campaign never delays an access code, and we help you meet the requirements for commercial SMS in Mexico.
How much does bulk SMS cost?
You pay for each message sent to the carrier. Encryption, webhooks and delivery reports have no additional cost. The final price depends on volume and on how many segments each message uses: a text longer than 160 characters, or with accents and emojis, may be billed as two. We explain it in detail in how much bulk SMS costs in Mexico.

Channels
Why SMS and not just WhatsApp or email?
Every channel has its place. SMS is the one that reaches any phone in seconds, with no app or data, which is why it is the main channel for critical messages and the backup for the others. See the SMS vs WhatsApp vs email comparison.
