Create a templates object with functions for each email type (welcome, passwordReset, connectionRequest). Each function takes data and returns subject, html, and text. Use a sendEmail function that looks up the template and sends it.

Create a transporter with nodemailer.createTransport using SES SMTP credentials (host, port, user, pass). Then call transporter.sendMail with from, to, subject, and text or html. Always handle errors with try-catch.
Send both. Use the html field for the HTML version and the text field for a plain text fallback. Some email clients and accessibility tools prefer plain text. Nodemailer supports both in a single sendMail call.
EAUTH means authentication failed (check SMTP credentials). 554 means the email was rejected (check if recipient is verified in sandbox mode). Timeout means the SMTP connection failed. Always log errors and provide user-friendly messages.
