📬 Trigger, Render, Deliver: Email Templates Made Easy with DotLiquid & EasyLaunchpad

Email is one of the most vital — yet frustrating — parts of any SaaS product.

Whether it’s sending a password reset, welcome message, or invoice, developers often struggle with:

• Designing clean, responsive templates

• Injecting dynamic content

• Handling different environments (dev, staging, prod)

• Debugging delivery issues

• Scheduling or retrying failed emails

That’s why EasyLaunchpad .NET Core boilerplate ships with a built-in DotLiquid-powered email system — giving developers the ability to manage transactional emails easily, flexibly, and professionally from day one.

Why DotLiquid? And What Is It?

DotLiquid is a safe, powerful, and developer-friendly templating engine for .NET. It enables dynamic email content by using placeholders (tokens) like:

Hello {{User.FirstName}}, your order {{Order.Number}} has been shipped!

This means:

• You don’t hardcode values

• You reuse templates

• You personalize emails at scale

And yes — DotLiquid supports loops, conditions, and filters out of the box.

Email System Included in EasyLaunchpad

When you start a new EasyLaunchpad-based project, you already have:

✅ A centralized email sender service

✅ Support for SMTP and async background delivery

✅ DotLiquid rendering with token support

✅ Built-in template structure (stored in DB or flat files)

✅ Admin dashboard to manage and preview templates

✅ Easy token injection from any module (auth, payments, onboarding, etc.)

You don’t just get “email support” — you get a full-featured email engine that scales with your SaaS.

Template Example: Password Reset

Inside the system, you’ll find default templates for:

• Account registration

• Email verification

• Password reset

• Payment confirmations

• Plan upgrade/downgrade

Here’s a simplified version of the Password Reset template:

<p>Hello {{User.FirstName}},</p>

<p>Click the button below to reset your password:</p>

<a href=”{{ResetLink}}”>Reset Password</a>

At send time, EasyLaunchpad .NET Core boilerplate replaces {{User.FirstName}} and {{ResetLink}} with actual values passed into the email model.

Triggering Emails: How Developers Use It

Need to trigger an email after a user signs up?

You can call:

await _emailService.SendAsync(“WelcomeEmail”, user.Email, model);

Where:

• “WelcomeEmail” is the template key

• user.Email is the recipient

• model contains token values like FirstName, PlanName, TrialEndDate

It’s fast, intuitive, and works across all modules (auth, payments, onboarding).

Managing Templates from the Admin Panel

You don’t need to redeploy your code just to fix a typo in an email.

The built-in Admin Panel lets you:

• View and edit templates

• Test rendering with sample data

• Enable/disable specific templates

• Assign templates to specific actions (user created, license expired, etc.)

This is a huge win for product teams, especially when scaling or iterating on your messaging.

Test and Preview System

Don’t worry about sending broken emails in production.

EasyLaunchpad .NET Core boilerplate gives you:

• Live previews of rendered templates

• Sample data loader for each template

• Logs for each email sent via Serilog

• Retry logic for failed deliveries (via Hangfire)

This level of control is unheard of in most boilerplates — but essential for real apps.

Background Processing with Hangfire

All emails are dispatched using Hangfire background jobs, meaning:

• No slow responses for users

• Retry on failure logic is built-in

• You can scale email delivery with queued workers

If your SMTP server goes down? Jobs retry.

If your traffic spikes? Jobs queue.

It’s bulletproof.

Multi-Environment Ready

The email system is environment-aware:

• Use test SMTP credentials in staging

• Production keys only activate in prod

• Disable real delivery when ENV=Development

No more accidental emails from localhost.

Design That Matches Your Brand

Each email template supports:

• Custom CSS styling

• Logos and header/footer blocks

• Token-based personalization

You can build a professional-looking brand email system in hours — not days — with no need for third-party editors.

Licensing and Feature Access

Want to restrict email features to certain plans?

The built-in Packages & Licensing system allows you to:

• Enable premium email templates only for Pro users

• Add usage limits (e.g., 10 emails per day for Free plan)

• Track email quota via background metrics

This makes your email system a part of your monetization strategy — not just a communication layer.
