If you've already used the text marketing setup wizard to configure the welcome message that customers receive after signing up for your text message marketing, you can update it using the new & improved text marketing setting page.
To get started, navigate to the Nurture app. Next, click Settings from the App menu, then select Customize Welcome Message from the settings menu on the left side of the page.
From there, enter your new welcome message and click Save.
If your welcome message is updated successfully, you'll see the a confirmation message and your new message will be displayed in the Welcome Message panel near the top of the page.
