Which method suits you?
All five methods leave over the same Belgian gateway and cost the same per message. The difference lies in who initiates the sending and how much preparation it takes.
| Method | When to choose it | Technical knowledge | Typical volume |
|---|---|---|---|
| Web interface | You compose the messages yourself, whenever it suits you | None | 1 to 50,000 per campaign |
| Excel import | The list comes from another system and differs per campaign | None | 100 to 100,000+ per campaign |
| REST API | Messages need to leave automatically from your own software | Developer needed, one-off | Continuous, without an upper limit |
| Mail2SMS | Your system can only send email, not call an API | None | A few to hundreds per day |
| Windows software | You prefer working from the PC, independent of the browser | None | 1 to a few thousand per campaign |

SMS gateway & REST API
Integrate SMS sending into your CRM, webshop or application via our documented REST API. Includes webhooks for delivery reports, an official PHP SDK on GitHub and code examples for PHP, Python, Node.js, Ruby, C# and PowerShell. Operational in minutes.
Mail2SMS & MailNoti
Mail2SMS — send an email that is automatically converted into an SMS message. Works from any email program (Outlook, Gmail, Apple Mail…), without installation or API integration.
Address your email to the mobile number with country code followed by @sms2.eu (e.g. 32496123456@sms2.eu), put your personal API token in the subject and type your message — the text leaves immediately as an SMS via our Belgian gateway.
MailNoti — create a personal address (yourname@noti.smsbox.be) and link it to one or more mobile numbers. Every message to that address is automatically forwarded as an SMS — ideal for system and server alerts that can only send email.

Shortcode — short, recognisable and professional
SMSBOX has its own shared shortcode — a short number (4–6 digits) that is easy to remember and comes across professionally in your communication. Immediately available as the sender for your campaigns, opt-in flows, votes and contests — nothing to apply for. Your customers reply directly to the shortcode and the message lands straight in your dashboard or in your system via webhook.
