Lovable: Authentication Emails from Custom Domains
LovableLovable now sends authentication emails (sign-up confirmations, password resets, magic links) from the app's custom domain instead of a generic Lovable address. This removes a common friction point where end users received auth emails that appeared to come from an unfamiliar sender, improving deliverability and brand trust for production applications.

Authentication Emails from Custom Domains
Lovable updated its authentication system on March 16, 2026, to send transactional emails from the application's custom domain rather than from a generic @lovable.app or similar Lovable-branded address.
The Problem This Solves
When developers build applications with Lovable's built-in authentication, the platform sends emails for common auth flows: sign-up confirmations, password reset links, magic link sign-ins, and email verification. Previously, these emails came from a Lovable-branded sender address, which created several issues:
- End users didn't recognize the sender, leading to confusion about whether the email was legitimate
- Email deliverability suffered because the sending domain didn't match the application's domain
- Brand consistency broke down when users received emails from
lovable.appwhile interacting with a completely different branded application
How It Works Now
For applications configured with a custom domain, Lovable automatically routes authentication emails through that domain. The emails appear to come from the application itself rather than from Lovable's infrastructure. This requires no additional configuration beyond having a custom domain already set up — the change applies automatically.
Why This Matters
Custom domain email sending is a standard expectation for production applications. Without it, apps built on Lovable looked obviously platform-hosted to end users, undermining the professional appearance that custom domains are meant to provide. This update closes that gap, making Lovable-built applications indistinguishable from traditionally developed ones in terms of email communications.
