Smart Attachment Routing for Text Messaging (MMS or URL) Follow

Salesmate allows you to send images, videos, documents, and other files through text messages using either MMS or secure URL delivery. When attachments are smaller in size, they are sent directly as MMS. If the total attachment size becomes larger than 5 MB, Salesmate automatically converts the attachments into secure downloadable links so you can continue sharing large files without interruption.

This enables you to share large videos, documents, and media files without being restricted by carrier MMS limits.

Prerequisites

Before sending large attachments through URL delivery, ensure that:

• URL Shortener is configured for your account.
• You have access to a Unified Inbox number.

For more information, see the URL Shortener setup documentation here.

How Attachment Delivery Works

Salesmate continuously calculates the combined size of all attachments added to a message.

When Total Attachment Size Is Less Than 5 MB

• MMS is selected by default.
• Attachments are delivered directly within the message.
• You can manually switch the delivery method to URL if preferred.
• Send options remain available.

When Total Attachment Size Exceeds 5 MB

• MMS becomes unavailable.
• URL delivery is automatically selected.
• Each attachment is uploaded to Salesmate's secure storage.
• Every file is converted into an individual shortened URL.
• URLs are included in the SMS message body.

Delivery Method Options

MMS Delivery

MMS is available when:

• Total attachment size is less than 5 MB.
• A supported Unified Inbox or Text Inbox number is selected.

Benefits:

• Attachments appear directly within the message.
• No additional storage charges apply.

URL Delivery

URL delivery is available for Unified Inbox numbers.

Benefits:

• Supports large files and high-resolution media.
• Generates trackable shortened links.
• Allows sending files beyond MMS carrier limitations.

Attachments are automatically converted to shortened URLs when:

• Total attachment size exceeds 5 MB.
• Or URL delivery is manually selected.

File Limits and Retention

Attachment Limits

• Maximum 10 attachments per message.
• Total file size supported up to 500 MB per message.

MMS Delivery

For attachments under 5 MB sent through MMS:

• Standard MMS carrier charges apply.
• No attachment storage fees are charged.

URL Delivery

For attachments delivered as URLs:

Two charges apply:

1. Standard SMS charges for the text message.
2. Attachment storage charges for uploaded files.

Storage pricing:

• $0.002 USD per MB
• Rounded up to the nearest MB
• Charged at send 

Important Notes

• The 5 MB limit is calculated using the combined size of all attachments.
• Multiple files under 5 MB each may still trigger URL delivery if their combined size exceeds 5 MB.
• URL delivery remains available even when automatic link shortening for text messages is disabled.
• Storage charges apply regardless of whether the recipient opens the attachment link.
