Transactional Email Service Integration

Job ID: 39228578

Budget: $15 – $25 USD

I've developed a tool on lovable.dev and need help integrating a transactional email service. The tool can be viewed here: https://fair-holiday-harmony.lovable.app/.

Here's what I've already done:
- The project is fully developed and available on GitHub.
- I've created a structured emailService.ts file with placeholder functions that need to be implemented.
- Improved securityUtils.ts with better token generation/validation (though it still needs enhancement for production).
- Core components have been modified to use the email service instead of console logs.
- A comprehensive DEVELOPER_GUIDE.md with detailed instructions has been added.

What I need from you:
- Choose a third-party email service provider (I suggest SendGrid).
- Update the email service functions with actual API calls.
- Enhance the token security for production use.
- Test the complete email flow.

The email service will primarily be used for sending transactional emails, with a specific focus on user notifications such as inviting a second user to confirm or edit data.

Ideal skills for this job include proficiency in TypeScript, experience with email service integration (preferably SendGrid), familiarity with GitHub, and a solid understanding of security measures for production environments.
