How do I style HTML emails?
Use inline CSS (not external stylesheets) since most email clients strip <style> tags. Use tables for layout (many clients don't support flexbox). Keep it simple: header with brand color, content section, and a call-to-action button. Test with mail-tester.com for spam score.

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.
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.
