There any many ways to utilize an email server in a web app.
You can use a package like nodemailer , but since you’re a vibecoder with little knowledge of coding, I’d recommend you prompt the model to use a service like web3Forms.
If you’re just looking to send general emails out and you aren’t interested in code at all, then using a service like MailChimp or ConstantContact may work just fine for your use case.
I think you hit on a Startup idea. Curated content based on the personal individual as opposed to the generalized demographics. It’s something that I haven’t seen though other mailing services. A service like this would be possible now with the advanced of AI.
