MMS (Multimedia Messaging Service) allows you to send images alongside text in SMS campaigns and automation, unlocking a more engaging way to connect with your audience than traditional marketing channels.
Images make your messages more eye-catching and help customers visualize products or offers before they click.

Differences Between SMS and MMS
SMS and MMS are both powerful messaging channels, but they serve different purposes. Understanding their differences helps you choose the right format for your marketing strategy.
Feature | SMS | MMS |
Character limit | Up to 160 characters | Up to 1,600 characters |
Media support | Text only | Text + 1 image |
Device compatibility | All mobile phones | Smartphones only |
Availability | Worldwide | US and Canada only |
Cost (US/Canada) | $0.015 per message | $0.045 per message (3×) |
Use SMS when you need to send short, time-sensitive messages, reach all device types (including basic phones), or run cost-effective, high-volume campaigns.
Use MMS when you want to include visuals, create more engaging messages, or promote campaigns like product launches, flash sales, or events.
💡 Tip: Use MMS for the initial, visually engaging message, then follow up with SMS for cost-efficient reminders.
How to Send MMS
To create an MMS, click Select file and add an image to your SMS message. You can choose an image from the library or upload one from your computer. That’s it! Your message will be sent as MMS.
MMS in Campaigns
Go to Campaigns → SMS → Create SMS Campaign. In the Content step, click Select File. Upload an image from your library or computer (max 500 KB).
MMS in Automation
Go to Automations → open or create a workflow. Add or edit an SMS block. Click Select File and upload your image (max 500 KB).
💡Preview your MMS for US/CA recipients to see how it will appear once delivered.
MMS Best Practices
Show products visually. When promoting a product, include an image so customers see exactly what they're buying. This reduces friction and increases click-through rates.
Lead with MMS for high-impact promotions. For flash sales or new launches, send an MMS first to grab attention. Follow up with text-only SMS reminders to balance cost and engagement.
Pair MMS with text-only SMS. Use MMS for your first message (visual impact) and SMS for reminders (cost efficiency). This maximizes engagement without overspending.
