# Custom Return-Path

The **Return-Path** (also known as the envelope sender or `bounce` address) specifies where receiving mail servers send non-delivery reports (NDRs) and bounce notifications.

## Why Customize Your Return-Path?

By default, Mailofly uses a shared return-path address (e.g. `bounces@mail.mailofly.com`). Setting up a custom return-path allows you to:

* **Achieve Full SPF Alignment**: SPF authentication passes under your own domain name (e.g. `pm.yourdomain.com`), satisfying strict DMARC alignment requirements.
* **Brand Consistency**: Removes third-party sending signatures in header previews.

## DNS Setup

When adding a domain in Mailofly, you will be prompted to add a CNAME record for your return-path subdomain:

| Type    | Name / Host         | Target / Value          |
| :------ | :------------------ | :---------------------- |
| `CNAME` | `pm.yourdomain.com` | `feedback.mailofly.com` |
