Message limitations

There are certain limitations in place for each message that is sent on Symphony. These limitations are detailed below:
Note: The limitations are only applied to the Symphony Desktop Application (SDA) or browser version.

  • The current limitation for a message is maximum of 30,000 characters.
  • This includes no more than 40 hashtag/cashtags in the same message.
  • The limit for @mentions is also 40 in the same message.

Attachments have their own set of limitations. Refer to the Knowledge Article found here on attachment limitations.
