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.
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.
