If you already send newsletters from your own domain, you may have set it up the old way: an SPF TXT record, a DKIM TXT record, and sometimes MX records. That still works, and nothing changes unless you choose to upgrade.

But there's now a simpler, more secure setup, and moving to it takes one click.

## What's new

The new setup is **all CNAME records** – no TXT records to copy by hand, and no MX records on your side:

- **One CNAME** at your sending subdomain (for example `send.yourdomain.com`) pointing at `email.magicpages.co`. This publishes SPF for you, so there's no SPF TXT record to maintain.
- **Two DKIM CNAME records** (`pdk1._domainkey…` and `pdk2._domainkey…`) pointing at Mailgun. These use 2048-bit keys that rotate automatically – stronger than the old static key, and you never have to touch them again.
- An optional tracking CNAME for open and click analytics.

Your subscribers see exactly the same "from" address they always have. This is purely about the records behind the scenes.

## How to upgrade

1. Open your Magic Pages customer portal and go to the **Newsletter** tab.
2. If your domain is eligible, you'll see an **"Upgrade email security"** banner in the Email Configuration section.
3. Click it. We'll open the DNS Setup Guide with a single change that **adds** the new CNAME records and **removes** the old TXT records for you.
4. That's it. Your newsletters keep sending throughout – there's no downtime and no interruption.

## Do I have to do this?

No. Existing setups keep working exactly as they are. The upgrade is opt-in, and you can take it whenever suits you. If you'd rather leave things as they are, you don't need to do anything.

## Why a subdomain, not your main domain?

A common question: "Can't I just send from my main domain directly?" Your **from** address can absolutely be your main domain (for example `newsletter@yourdomain.com`) – that's what your subscribers see. But the technical *sending* domain has to be a subdomain, because your main (apex) domain can't hold the CNAME records email providers need. We handle that distinction for you, so you get the best of both: a clean from address on your main domain, and a properly configured subdomain doing the work behind the scenes.
