# Sending out MMS messages

### **What is an MMS?**

MMS stands for "Multimedia Messaging Service," and it is used to send more complicated messages than SMS messages. MMS messages in Daisychain can can include images and/or up to 1,600 characters of text.

### **How do I send out an MMS message?**

There are two ways to send MMS messages in Daisychain:

#### **Adding several SMS segments worth of text**

If you send a long text in Daisychain which uses multiple SMS segments, we will automatically convert that message to an MMS if it is more cost-effective for you.

#### **Adding Pictures**

In the message composition window, click the image icon and select your file.

### Other questions

#### **How big can my image file be?**

Your file should be 500kb or less. If you need to resize your image, you can try using an online tool like [Image Resizer](https://imageresizer.com/).

#### **What dimensions should I use?**

In order to keep the file size small and the image easily viewable on a mobile phone, we generally recommend:

* Make your images square
* Making your image no more than 500px wide

#### **Any other tips?**

* **Don't Use Transparent Backgrounds:** These can appear as solid, randomly-colored backgrounds in the message thread, causing the image to look different than intended.
* **Consider using Charms and GIFs:** engaging, personalized content may get a better response than just text or a stock photo.
* **Use High Color Contrast:** Make sure the foreground and background colors are clearly different to prevent the image from appearing blurry or monochromatic.
* **Don't Use Borders:** On some iOS devices, borders may be displayed off-center.
