Concise
Flash messages should be informative, yet concise. Try to limit the message to a single phrase or one short sentences. Use positive, clear language.
Warning links
In the case of alerts or warnings, it is okay to include a second sentence that is a link to a followup action or more information.

Do
Success links
For success messages when something new has been created, it is usually a good idea to provide a link to go to that item.

Do
Success messages
Confirmation or success messages should appear when the user completes an action, confirming that the action has successfully completed. For example:
Item deleted
Item saved
Item created
Task completed
File uploaded
Concise
These messages should be clear and concise. Don’t include unnecessary words, including articles like “the" and "a". It’s almost always unnecessary to include “successful” or “successfully”, since that is redundant.
Warnings and alerts
See Error Handling.
