Sending attachments in Shout (MMS settings)
There are two ways to send attachments:
- MMS attachments are sent directly to a device via the wireless carrier and displayed in the device's messaging app.
- Short links are sent as a text link. In most cases, recipients will need to click or tap the link to see the file.
Choose how to send an attachment
From a message composer:
- Click the paperclip icon to attach a file
- Select a file to attach
- The file will appear as a thumbnail above your message
- Click on the MMS or Link icon on the thumbnail to choose how the attachment should be sent, if possible
- Some attachments can’t be sent as MMS. See limitations below.
Cost of MMS and short links
An additional segment counter is shown in a message composer after you attach a file.
- MMS attachments cost two message segments each
- Short links cost one message segment each
Default attachment options
To choose your default attachment settings:
- In the left navigation, click Settings
- Under Services, click Texting
- Under MMS Settings toggle the checkbox to select the way Shout should send attachments by default
Limitations of MMS messages
Carriers impose limitations on MMS messages. Please note:
- MMS messages can be .jpg, .png, .tiff, .mp4, .ac3, .wav, .gif and some others.
- MMS messages sent via a Marketing number will be limited to 300 KB in size.
- MMS messages sent via a Customer Service number will be limited to 922 KB in size.
- Images (.jpg, .tiff, .png) uploaded to send as MMS messages are compressed to fit carrier limitations. Compression may cause a reduction in quality.
- All GIFs are limited to 300 KB in size.
- Any attachment exceeding these limitations will be sent as a short link regardless of your default settings.
- To maintain control over the quality of your uploaded images, consider compressing them before uploading them to Shout to ensure they are less than the size limits described above
- Use MMS images in all types of messages, including individual messages, group messages, bots, and drip campaigns.
- Short links have no file type restrictions and will accept sizes up to 20MB.
