An automated email system in Bubble sends emails based on triggers like user signup, cart abandonment, or inactivity periods. This tutorial covers creating email templates stored in the database, building trigger-based workflows for welcome emails and order confirmations, scheduling delayed emails for abandoned cart recovery and inactivity re-engagement, and managing all templates from a central admin interface.
Overview: Automated Email System in Bubble
This tutorial shows you how to build a complete email automation system that sends the right email at the right time based on user actions and inactivity patterns.
Prerequisites
- A Bubble app on a paid plan
- An email service configured (SendGrid, Mailgun, or built-in)
- Backend workflows enabled
- Basic understanding of scheduled workflows
Step-by-step guide
Create the email template management system
Create the email template management system
Create an 'EmailTemplate' Data Type with: name (text — identifier), subject (text), html_body (text), trigger_type (text — welcome, order_confirmation, cart_abandon, inactivity), delay_minutes (number — how long to wait before sending), is_active (yes/no). Populate templates for: welcome email (delay: 0), order confirmation (delay: 0), abandoned cart reminder (delay: 60 minutes), inactivity re-engagement (delay: 10080 minutes / 7 days). Build an admin page where you can edit each template's subject and body without touching workflows.
Expected result: Email templates are stored in the database and manageable from an admin interface.
Build instant trigger emails
Build instant trigger emails
For immediate emails: in the signup workflow, after creating the user, search for the active EmailTemplate where trigger_type = 'welcome'. Apply find-and-replace to substitute tokens like {{user_name}} with the user's data. Send the email. Repeat for order confirmation: after a successful payment, send the order_confirmation template with order details. These emails fire instantly as part of the triggering workflow with zero delay.
Expected result: Welcome and order confirmation emails send immediately when triggered.
Schedule delayed emails for cart abandonment
Schedule delayed emails for cart abandonment
When a user adds items to their cart, schedule a backend workflow called 'send_cart_reminder' to run after the delay (e.g., 60 minutes). Pass the user and cart reference as parameters. When the workflow runs, first check if the cart is still active (not converted to order). If yes, send the abandoned cart email with cart items listed. If the cart has been converted, do nothing. This prevents sending reminders to users who already completed their purchase.
Pro tip: Schedule a series of reminders: 1 hour, 24 hours, and 72 hours after abandonment. Each subsequent email should increase urgency or offer a small discount.
Expected result: Users who abandon their cart receive a reminder email after the configured delay.
Build inactivity re-engagement emails
Build inactivity re-engagement emails
Create a scheduled backend workflow called 'check_inactive_users' that runs daily. Search for users where last login date is more than 7 days ago (or your threshold) and who have not already received an inactivity email recently (check an 'inactivity_email_sent' date on User). For each inactive user, send the inactivity re-engagement template with personalized content. Update the User's inactivity_email_sent date to prevent duplicate sends. Schedule escalating messages: 7 days, 14 days, 30 days.
Expected result: Inactive users receive re-engagement emails at scheduled intervals to encourage return visits.
Track email performance and manage unsubscribes
Track email performance and manage unsubscribes
Create an 'EmailLog' Data Type: template (EmailTemplate), recipient (User), sent_at (date), opened (yes/no), clicked (yes/no). Create a log entry for every email sent. If using SendGrid or Mailgun, set up webhooks to receive open and click events and update the EmailLog. Build a dashboard showing: total emails sent per template, open rates, click rates, and unsubscribe rates. Add an 'email_subscribed' yes/no field to User. Check this before sending any non-transactional email. Include an unsubscribe link in every marketing email. RapidDev can help implement advanced email analytics with A/B testing.
Expected result: Email performance is tracked and users can unsubscribe from marketing emails.

Why it's a problem: Sending abandoned cart emails after the user has already completed the purchase
How to avoid: Always check if the cart has been converted to an order before sending the reminder
Why it's a problem: Not including an unsubscribe option in marketing emails
How to avoid: Add an unsubscribe link in every non-transactional email and honor opt-outs immediately
Why it's a problem: Sending duplicate inactivity emails to the same user
How to avoid: Track when each type of email was last sent to the user and skip if already sent within the defined period
Best practices
- Always check conditions before sending delayed emails
- Include unsubscribe links in all non-transactional emails
- Track email open and click rates for performance optimization
- Store templates in the database for easy editing without code changes
- Personalize emails with user data for better engagement
- Test all email templates across email clients before going live
- Respect user email preferences and opt-out requests immediately

Frequently asked questions
Do I need a third-party email service?
Bubble's built-in email works for low volume. For production apps, use SendGrid or Mailgun for better deliverability, tracking, and higher sending limits.
How many automated emails can I send per month?
This depends on your email service plan. SendGrid's free tier allows 100 emails/day. Bubble's built-in email has no official limit but is not designed for high volume.
Can I A/B test email subjects?
Yes. Create two templates with different subjects and randomly assign users to each variant. Track open rates per variant in EmailLog to determine the winner.
How do I prevent emails from going to spam?
Use a reputable email service (SendGrid/Mailgun), set up SPF, DKIM, and DMARC records on your domain, and avoid spam trigger words in subjects and content.
Can I schedule emails for specific times?
Yes. Use Schedule API Workflow with a specific date/time. Schedule emails for business hours in the recipient's timezone for better open rates.
Can RapidDev help build email automation?
Yes. RapidDev can implement complete email automation systems in Bubble including multi-step sequences, A/B testing, analytics, and deliverability optimization.
