Upgrading Your Newsletter Sending Domain to the New Setup

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.
