SMS Attachment Size Limits
Sending multimedia messages (MMS) via SMS is a powerful way to engage with your audience. However, it's crucial to understand the size limitations imposed by carriers and the CRM to ensure successful delivery.
Details
MMS Capability: Ensure your number is MMS capable. This information can be found in your account settings under the "phone numbers" tab.
Attachment Limits: The CRM supports up to 10 attachments, with the total size of the text and attachments not exceeding 5 megabytes. However, carrier limits vary, typically ranging from 300 kilobytes to 3.5 megabytes. For optimal delivery, it's recommended to keep attachments under 500 kilobytes.
Supported File Types: JPEG, PNG, and GIF are supported for SMS attachments.
Special Considerations: For toll-free numbers, ensure attachments are 600 kilobytes or smaller due to specific carrier restrictions.
Troubleshooting Tips
If an MMS fails to send, check the total size of your message and attachments. Reducing the file size may resolve the issue.
Verify that your number is MMS capable and that the file types are supported.
FAQs
Can I send MP4 files via SMS?
Currently, MP4 files cannot be sent directly. However, recording a video in the mobile app generates a clickable link for recipients. Ensure the link matches your domain and client's brand name for compliance with carrier regulations.
Email Attachment Size Limits
Email servers impose size limits on attachments to prevent server overload. Understanding these limits is key to ensuring your emails are successfully received.
Details
Server Limitations: Most email servers have a maximum size limit for emails, which includes the body text and attachments. Exceeding this limit results in bounced emails.
Provider Variations: Attachment size limits vary by email provider. For instance, Mailgun supports a maximum message size of 25 megabytes. It's advisable to keep attachments as small as possible to accommodate different providers.
Error Notifications: If an email exceeds the maximum size, you'll receive an error notification in your conversation tab, typically indicating the attachment size exceeded the allowable limit.
Troubleshooting Tips
To avoid exceeding size limits, consider compressing attachments or using lower-resolution images.
If an email bounces due to size limits, try reducing the attachment size and resending.
FAQs
Can I bypass maximum email size limits?
No, bypassing these limits is not possible. Instead, upload the files to a cloud service and include a download link in your email as a workaround.
