How to manage email requests in Bubble

In any workflow, add the 'Send Email' action (found under Email in the action list). Configure: To (recipient email — dynamic expression like Current User's email), Subject (text with optional dynamic inserts), Body (HTML or plain text with dynamic data), and optionally CC/BCC. The body supports HTML for formatting. Insert dynamic data using Bubble's expression builder: click 'Insert dynamic data' and select fields like Current User's first_name or the result of a previous workflow step. This uses Bubble's built-in email service (Postmark) which works for basic needs.

Create a SendGrid account at sendgrid.com (free tier: 100 emails/day). In SendGrid, go to Settings → API Keys and create an API key with Mail Send permissions. In your Bubble app, go to Settings → Email. Enter your SendGrid API key in the SendGrid field. Configure your sending domain: in SendGrid, go to Settings → Sender Authentication → Authenticate Your Domain. Add the required DNS records (CNAME entries for DKIM and SPF) at your domain registrar. Verify the domain in SendGrid. Your emails now send through SendGrid with proper authentication.

For consistent branding, create email templates using HTML. Build a template with your logo, brand colors, and layout. Store the template HTML in an Option Set attribute or a Data Type field. In your Send Email action, use the template HTML as the body and insert dynamic data using Bubble expressions. For example: replace {{first_name}} in your template with the recipient's actual first_name using Bubble's Find & Replace text operator. Alternatively, use SendGrid's Dynamic Template feature: create templates in SendGrid's dashboard and call them via the API Connector with dynamic variables.

Set up automated email workflows for: Welcome email (trigger: when User is signed up), Order confirmation (trigger: when Order status changes to confirmed), Password reset (built into Bubble's auth system), Reminder emails (scheduled backend workflow), and Weekly digest (scheduled backend workflow running every 7 days). For each workflow, use the Send Email action with the appropriate template and dynamic data. For bulk emails (newsletters), use a recursive backend workflow that sends one email at a time with a pause between sends to avoid rate limits.

In SendGrid's dashboard, monitor key metrics: Delivery Rate (target: 95%+), Open Rate, Bounce Rate, and Spam Reports. Set up SendGrid webhook notifications in the API Connector to receive delivery status callbacks. Create an Email_Log Data Type with fields: recipient, subject, status (sent/delivered/bounced/opened), and timestamp. When SendGrid sends a webhook for a bounce, update the Email_Log and mark the user's email as invalid in your database. Suppress future emails to bounced addresses to maintain your sender reputation.
