# Vercel docs recommend unmaintained library that breaks newer nextjs applications

Moving from this GitHub issue: https://github.com/vercel/vercel/issues/11359

https://vercel.com/guides/sending-emails-from-an-application-on-vercel

The guide above recommends `mailing` to send emails from Vercel applications, but this package appears to be unmaintained since before app router was implemented. It breaks if imported into newer NextJS applications and throws errors about ugilfy-js, which is one of its dependencies.
