Your Shift4Shop Website has system messages already built in to warn, thank, or inform customers during certain situations on your online store. These system messages range anywhere from adding invalid credit card information to thanking them for signing up for the Mailing List. As with most functions in Shift4Shop, you have the ability to customize these messages to display whatever you want.
Edit System Messages
To edit the system messages:
Go to Settings > Design > Themes & Styles.
Once there, scroll down the page and click on the Edit button under "System Messages."
In the Message field, edit the message you would like to display to the customer.
4. Click Save when done.
Also, as with most text fields you can edit within Shift4Shop, basic HTML coding can be used to accentuate your text if/when necessary!
