I'm working on an email web client using NextJS where users can connect their Gmail or Outlook accounts to send and receive emails, similar to what Superhuman offers. I'm currently focused on backend integration and I'm unsure about the most cost-effective methods. Is it enough to use OAuth 2.0 for user connections, or should I consider services like Resend or AWS SES? I've researched those options and I'm also using Supabase, which has built-in OAuth. I plan to deploy on AWS eventually and am open to learning about SES if it's a good fit. As I'm only integrating Gmail and Outlook for now, I'd prefer to avoid complicated setups with SMTP and IMAP. If anyone has suggestions on the best practices or alternative solutions, I'd love to hear them!

What would make your email client more appealing than Gmail or Outlook? It's crucial for your service to at least match their features like rules and folders. Building a full-fledged email client alone seems pretty ambitious to me.
Is this project just a side gig for you, or are you planning to turn it into a full business?
It's just a side project for now, but I'd like to make it practical enough for others to use too if it all works out. I’ve explained more about my vision in other replies!
Actually, my email client is just part of a larger web app that connects multiple communication channels. Users can manage messages from WhatsApp, Telegram, Instagram, and more in one place, customizing workflows without dealing with multiple apps. I get that competing with established giants is tough, but my focus is really on integration and convenience, which addresses my own frustrations with managing messages.
