What it helps with — Domains, hosting and email
Two companies.
One job.
Neither one documents the other half.
Your registrar’s help pages stop at your host’s edge. Your host’s stop at the registrar’s. The part in between — the part that takes your site or your mail down — is the part nobody writes down.
What it runs
- Point a domain at a new host
- A record or CNAME, apex or www, at the registrar or at the host — four decisions that look interchangeable and aren’t.It reads the panel you’re actually in — Hostinger, GoDaddy, Namecheap, Cloudflare — and names the field on your screen, not the one in a screenshot from 2021.
- Move hosting without downtime
- The old site has to keep serving while the new one comes up, and TTL decides how long you’re exposed.It gets the TTL lowered before anything else changes, then holds the order of operations for you across both dashboards.
- Email records that stop spam
- SPF, DKIM and DMARC. One SPF record per domain is a hard rule, and a second one silently breaks the first.It checks what’s already there before adding anything, and tells you when a provider’s copy-paste instructions would collide with a record you already have.
- Mail broken after a migration
- The site came back and the email didn’t. Usually MX records that went with the old host’s default DNS.This is the acute one. It starts from what’s live now rather than from what should have happened, because you need mail back today.
- Custom domain on a deployment
- Vercel, Netlify, Framer, Webflow, Render. Each wants a slightly different record and each verifies differently.It works across both screens — the platform’s domain settings and the registrar’s DNS panel — and waits with you for propagation instead of declaring victory early.
- Move a domain between registrars
- Unlock, auth code, 60-day transfer locks, and the DNS that may or may not travel with it.It tells you what will break at the moment of transfer, before you start it, rather than after.
From a real session
The record you were about to delete.
Forty minutes earlier in the same session, the goal had mentioned that mail ran on the same domain. Nothing on the DNS panel says so. The panel shows a list of records and a delete button next to each one.
Holding that one fact across forty minutes is the whole product.
Minute 41
Before you delete that old record — your email runs on this domain too. Removing it takes your mail down with the site.
Worth knowing first
- It can be wrong
- It reads one still frame at a time and tells you what it sees. It is not certain, and it says so when it isn’t.Read the step before you act on it. DNS changes are slow to undo.
- You make every change
- It never clicks, types or edits a record. It tells you which field, and you fill it.You end up able to do it again, which is the point.
- Chrome or Edge, on a computer
- Desktop or laptop. English.A phone can’t share a screen this way.
