PTo start building your database, you'll need to create custom data types for different entities in your marketplace. Here’s how to do it:

Navigate to the Data Tab:

• Go to the Bubble editor and click on the 'Data' tab.

Add New Data Types:

• Click on 'Data types' and then 'New type'. Name it according to the entity you want to create, such as Shop or Product.

Define Fields for Each Data Type:

• For each data type, add fields that capture relevant information. For example:

Shop :

• Name (text)
• Description (text)
• Location (geographic address)
• Owner (user)

Product :

• Name (text)
• Description (text)
• Price (number)
• SellerShop (Shop)
• Genre (option set: Book Genre)
• Format (option set: Book Format)

Implementing Option Sets

Option sets are useful for defining pre-defined choices that users can select from, such as book genres or formats.

Create Option Sets:

• In the same ‘Data’ tab, click on 'Option sets' and then 'New option set'. Name it appropriately, such as Book Genre or Book Format.

Add Options to Option Sets:

• For each option set, define the possible values. For example:
• Book Genre: Fiction, Non-Fiction, Mystery, Sci-Fi
• Book Format: Hardcover, Paperback, eBook

Link Option Sets to Data Types:

• Go back to your custom data types like Product, and add fields that reference these option sets.

By following these steps, you establish a solid foundation for your marketplace app’s database structure on Bubble.io.

This setup not only organizes your data but also simplifies future enhancements and integrations into your marketplace app.

3. Enhancing User Engagement with Backend Emails and Follow Functionality

Using backend workflows in Bubble.io for email communication between sellers and customers can significantly enhance user engagement in a marketplace app. These workflows automate email notifications, thereby improving the overall user experience without manual intervention.

Importance of Backend Workflows for Email Communication

Backend workflows allow you to set up automated processes that can handle complex tasks seamlessly. In a marketplace app, these workflows can:

• Send order updates to customers
• Notify sellers about new orders or inquiries
• Schedule promotional emails

By leveraging these functionalities, you ensure timely communication between users, which enhances trust and keeps them engaged on your platform.

Creating a Shop Admin Page

To manage these email communications effectively, you'll create a dedicated shop admin page. This page will serve as the control center for all email-related activities, allowing sellers to draft, delete, and schedule emails.

Steps to Create the Shop Admin Page:

1. Set Up the Page Layout

• Add a repeating group to list all emails.
• Include input fields for drafting new emails: Subject Line, Body Text, and Send Date.
• Integrate buttons for actions like "Send Email," "Save Draft," and "Delete Email."

2. Drafting Emails

• Use input fields for the subject line and body text.
• Save drafts in the database under a new data type Email with fields such as:
• Subject Line
• Body
• Send Date
• Status (e.g., Draft, Scheduled)

3. Deleting Emails

• Add a delete button within each email item in the repeating group.
• Set up a workflow that triggers when this button is clicked to remove the email from the database.

4. Scheduling Emails

• Create a backend workflow to handle scheduled emails.
• When an email is drafted and scheduled, store it with a send date.
• Use Bubble.io's API workflows to send emails at the specified time.

Implementing Email Features Using Backend Workflows

Backend workflows in Bubble.io enable you to automate complex tasks:

• Drafting Emails: Store drafts in the database so they can be edited or sent later.

• Action: Schedule an API workflow called send-email at email's Send Date
• Create Another API Workflow Named send-email
• Parameter: email
• Action: Send email using constraints on related follows; pull subject line and body from parameter email
• Integrate Workflow Triggers
• Trigger schedule-email workflow when an email is scheduled
• Trigger send-email workflow at the predetermined send date

Implementing these backend workflows will not only streamline your email management process but also ensure reliable communication between users in your marketplace app.

Enhancing user engagement through these functionalities makes your marketplace more robust and user-friendly, setting it apart from competitors who might not offer such seamless communication capabilities.

• Modify the delete workflow to show this popup first, then proceed with deletion if confirmed.

Managing Email Lists

• Regularly check and manage email lists through this admin interface.
• Enable additional functionalities like sorting or filtering emails based on criteria such as date or subject line.

This setup provides admins with full control over email communications within their marketplace app, ensuring that unwanted or outdated emails can be efficiently removed from the system.

Sending Scheduled Emails
