Do You Need a Custom Domain for a Newsletter?
No, you don't need one to send a newsletter. It works fine on a shared subdomain. A custom domain is a branding and ownership choice, not a requirement for delivery.
Do you actually need a custom domain to send a newsletter
Sending a newsletter and owning the domain it lives on are two separate questions. Email delivery, sign-up forms, and post publishing all work fine on a shared subdomain. What a custom domain changes is the URL readers see and remember: yourdomain.com instead of a platform's subdomain. If you're just starting out and want to see whether people actually read what you write, a shared subdomain costs you nothing and loses you nothing technically. The domain becomes worth it once the newsletter has an audience you want to build a lasting, portable brand around.

What changing your setup looks like (moving off a shared URL)
Point your domain
Add the DNS records Floggy gives you at whatever registrar you bought the domain from.
Wait for verification
Floggy checks the records and activates the domain once they resolve. DNS propagation timing depends on your registrar, not on Floggy.
Switch your newsletter over
New posts and outgoing newsletter emails use your custom domain going forward.
Clean up old references
Update social bios, past email footers, and anywhere else that still points at your old shared subdomain.
Custom domain plus newsletter plus analytics in one place
Custom domain
Connect your own domain on Pro and write from the same editor, no separate DNS product to manage.
Newsletter
Send posts to subscribers straight from the editor you already write in.
Analytics
See opens, clicks, and traffic without wiring up a third-party analytics tool.
Headless CMS
Manage custom collections through the same account, reachable by API, SDK, and CLI.
Agent publishing
Let an AI agent draft, publish, and run SEO on a schedule using the same CLI, on the same domain.
When it's worth upgrading from a free plan
Reasons to upgrade
Pros- You own the domain outright and can take it anywhere if you ever switch platforms.
- Newsletter emails and post links carry your own name, not a shared platform subdomain.
- One address to promote, instead of explaining a subdomain to new readers.
Reasons to wait
Cons- You have to buy and renew the domain yourself, which is one more thing to manage.
- If you're not sure the newsletter has an audience yet, a shared subdomain works fine and costs nothing to try.
- A custom domain adds a DNS step that a shared subdomain skips entirely.
Frequently asked questions
Do I need a domain for a newsletter?
No. Sending a newsletter works on a shared subdomain. A custom domain is about ownership and branding, not a requirement for delivery.
Is there a free email service with a custom domain?
On Floggy, the custom domain is a Pro feature; the free tier runs your blog and newsletter on a shared subdomain instead. Other platforms structure this differently, so check their current plan pages if you're comparing options.
Is a custom domain email worth it?
It's worth it once you have readers you want to keep long-term and a brand you don't want tied to someone else's subdomain. If you're still testing whether the newsletter has an audience, it's fine to wait.
Custom domains and newsletters: what's the real tradeoff?
The tradeoff is ownership versus simplicity. A shared subdomain has zero setup and no DNS to manage. A custom domain takes a short setup step but gives you an address you control and can move if you ever change platforms.
Do Buttondown or Ghost support custom domains?
We haven't verified their current plan details, and plan features change over time, so check Buttondown's and Ghost's own plan pages for what's included today. On Floggy, custom domains are a Pro feature alongside the newsletter, CMS, and analytics in the same account.
