Broadcast Overview
Message Length
Each messenger has a different maximum message length. This applies to plain text messages as well as media messages with captions. Generally, plain text messages can contain more characters than the captions of media messages. If the limit for the caption is exceeded, Whappodo automatically packages your broadcast separately into a media message without a caption and a text message. The text part thus appears separated from the media part.
