Email Template Variables Showing Blank in Lovable App
Emails sent from your Lovable app contain blank spaces or literal placeholder text where dynamic content should be — for example, 'Hello {{name}}' instead of 'Hello John', or 'Your order #{{orderId}}' with blank values.
This makes your app look unprofessional and can confuse users. They receive emails that don't contain the information they need, like order details, account information, or personalized content.
The issue might affect all emails or only certain templates, and might work correctly in development but fail in production.
Error Messages You Might See
Template variable 'name' is undefined
Cannot read property of null
Email sent but content is empty
Common Causes
- Wrong template syntax — Using {{ }} when the email service expects {{{ }}} or ${} or other syntax
- Variables not passed to send function — The email sending code doesn't include the dynamic data in the API call
- Async data not awaited — Data is fetched from the database but the email is sent before the query completes
- Case sensitivity — Template uses {{Name}} but code passes {name} (case mismatch)
- Null or undefined values — The data exists in the database but is null for some users
How to Fix It
- Check your email service documentation — Verify the correct template variable syntax for your email provider (Resend, SendGrid, etc.)
- Log the email data before sending — Add console.log to verify all template variables have values before the email is sent
- Add null fallbacks — Use default values for any variable that might be null: name || 'there'
- Test with hardcoded values — Replace variables with static text to verify the template renders correctly, then add variables back one by one
- Check async/await — Ensure all database queries are awaited before passing data to the email function

Basel Issmail
’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

Get HelpFrequently Asked Questions
Why do my emails work in testing but not production?
Common causes include different environment variables, different database data (test users have all fields filled, real users may have null fields), and different email service configurations between environments.
How can I preview my emails before sending?
Most email services offer a preview feature. You can also send test emails to yourself with sample data. Services like Resend and SendGrid have built-in template previews.
