How to Manage an International SMS Campaign?

Sending marketing SMS messages internationally represents a tremendous opportunity for businesses looking to communicate with their customers all over the world. But between local regulations, costs that vary by country, and technical requirements, an international campaign is not something you can improvise.

In this article, we present : how to effectively manage an international SMS campaign, while staying compliant and optimizing your performance.

1. Managing Sending Permissions: Respecting Local Rules

Each country has its own regulations regarding marketing SMS sending. Before launching any international campaign, it is essential to verify the legal requirements and obtain the necessary permissions where the law requires it.

A few concrete examples:

United Kingdom : sending is governed by the Privacy and Electronic Communications Regulations (PECR). Explicit consent from the recipient is mandatory.
Morocco : commercial SMS campaigns must be approved by operators. Messages must clearly identify the sender.
Canada : the Canada’s Anti-Spam Legislation (CASL) requires a clear opt-in and proof of consent.

On the platform, we help our clients with compliance for their international campaigns. Our teams are familiar with the legal requirements of each market and help you follow best practices to avoid any blocking or penalties. To submit a sending request to an international destination, you can

2. Managing Pricing: Anticipating and Controlling Costs

The cost of an international SMS varies depending on the destination country, the operator, and sometimes even the type of message (A2P, alphanumeric, Unicode, etc.).

Effective pricing management is therefore essential to keep your budget under control.

Key points to watch:

Price per country : some markets, such as the United States or Canada, have higher rates than intra-European sends.
Message length : a standard SMS = 160 characters (in GSM). Beyond that, it is split into multiple segments billed individually (Try the SMS character counter)
Tracking and personalization : shortened links, dynamic variables, and click tracking can affect billing.

3. Managing Opt-Outs: Guaranteeing the Right to Unsubscribe

Managing opt-outs is a legal obligation and a sign of respect for your recipients.
Regardless of the country, your contacts must be able to unsubscribe easily and free of charge from your communications.

Two main mechanisms exist:

The STOP keyword : by replying “STOP”, the contact is automatically removed from the sending list.
The unsubscribe URL : an unsubscribe link (often better suited to multilingual and international campaigns).

Please note: some countries require a specific mention. For example, in France, it is mandatory to display « STOP au 36XXX » for all marketing SMS messages.

On the SMS Partner platform, each message can automatically include an unsubscribe link or keyword compliant with local standards.
Your contact list is updated in real time to ensure full compliance with GDPR and international laws. ✅

4. Managing Phone Country Codes: A Technical Must

When sending SMS messages abroad, it is crucial to correctly format phone numbers by adding the international country code of the destination.

Examples of country codes:

France ?? : +33
Belgium ?? : +32
United Kingdom ?? : +44
Morocco ?? : +212

An incorrect format can prevent message delivery. Before any send, you must therefore clean and normalize your database to the international format (E.164).
