Help > Character limits
Forms typically have a character limit of 50,000 characters.
When you submit a form, we take the information and format it in a way that can be sent back to Slack. This is done using Slack's "Blocks" which have character limits (typically 3,000 characters).
To avoid this and allow you to send longer messages, we will split your message into multiple bocks if required.
If you have a need to send messages with more than 50,000 characters, let us know.
