Which countries can you send messages to using Campaigns?

With Campaigns, you can reach your audience across multiple messaging channels — but availability depends on the channel, the destination country, and local regulations.

Here’s how each channel performs globally.

SMS — global coverage

SMS enables you to reach customers almost anywhere in the world.

• ✅ Available in 200+ countries and territories 
• ✅ Supported across thousands of carrier networks
• ✅ Compatible with virtually all mobile phones

This makes SMS the most reliable option when you need to communicate at scale, across multiple markets.

Note that messaging requirements vary by country. Depending on the destination, you may need to:

• Register your sender ID
• Adapt your message content
• Comply with local regulations.

You can find detailed requirements in the Country Information section of the Sinch Build Dashboard.

RCS — expanding global coverage

RCS is a fast-growing channel that enables rich, interactive messaging experiences directly in the native messaging app.

Availability depends on carrier support and market adoption, which continues to expand worldwide.

With Campaigns, you can use a capability check to identify which recipients support RCS and target them accordingly.

WhatsApp — global, app-based reach

WhatsApp allows you to reach users globally, regardless of country, as long as they use the app.

• ✅ Available in most countries worldwide
• ❌ Only reaches users who:
  • Have WhatsApp installed
  • Are connected to the internet
  • Have opted in to receive your messages.

Reach depends on WhatsApp adoption in each country, which can vary significantly across regions.

MMS — limited availability

MMS is available in a small number of countries only.

• ✅ Supported in:
  • United States
  • Canada
  • Australia.
• ❌ Not available in other countries

In addition, MMS delivery depends on:

• Device compatibility
• Recipient mobile plan
• Carrier support.

MMS is most relevant for targeted campaigns in these specific regions.

What else can impact country availability?

Even when a channel is technically supported, delivery may be affected by:

• Local regulations and compliance requirements
• Carrier and network limitations
• Sender ID restrictions or registration rules
• Device and channel eligibility.
