Aftermarket monitoring watches the domain resale market for the names you already track, and tells you the moment one of them is listed for sale instead of dropping. It exists because the drop is not the only way a name leaves an owner: the good ones are often sold during the grace window, before they ever reach the public drop.
If you have ever watched a name for months, waited for it to expire, and then found it was already gone the day it became available, this is the reason. It did not drop. It was sold.
The two ways a name leaves an owner
When a domain expires, it can take one of two paths.
- The drop. It falls through its grace and redemption stages to a predictable public deletion, at which point anyone can register it for the standard price. This is the path an availability watch follows.
- The aftermarket. The registrar lists it for a fixed closeout price, or pulls it into a rising-bid auction, and it sells to a buyer. The name never reaches the public drop at all.
A person watching only for the drop sees the first path and is blind to the second, which is where most of the names actually worth having tend to go. A name with traffic, backlinks, or a clean spelling is worth more than a registration fee, so the registrar sells it rather than letting it fall back to the pool for anyone to grab.
What aftermarket monitoring does
Domainyze reads the domain aftermarket twice a day and matches every listing against your watch list. When a name you are already tracking is listed for auction or closeout, two things happen:
- Its lifecycle stage becomes Auction. This is visible to every account, on every plan. You see it on the domain and in your dashboard the same way you see any other lifecycle stage. An observation about a name is free.
- On a paid plan, you get an alert. The alert carries the marketplace, the sale type, the current price with its currency, and the deadline, whether that is an auction end time or a closeout drop time. How aftermarket alerts work covers this in full.
You do not add anything new for this to happen. Aftermarket monitoring rides on the watch list you already keep. The market is matched to your list, not the other way round, so you are never asked to sort a market of thousands.
Which marketplaces are covered
Coverage is GoDaddy and Dynadot, across their auction, closeout, and buy-now listings, refreshed twice a day. There is no fixed list of allowed extensions, so coverage is whatever those two marketplaces list. In practice that is led by the common extensions like .com, .co, .io, .net, .org, .app, .ai, and .dev, but it is not limited to them.
Auction, closeout, and buy-now
A listing is one of three shapes, and the difference matters because only two of them are treated as an event:
- Auction — a rising-bid sale that ends at a set time. Contested names go here instead of dropping. This moves a watched name to the Auction stage and can raise an alert.
- Closeout — a fixed, falling price the registrar sets on an expiring name before it deletes it. First to buy wins, no bidding. This also moves a watched name to the Auction stage and can raise an alert.
- Buy-now — a listing at a fixed asking price with no deadline. This shows up when you search the aftermarket, but a fixed price is information, not an event, so it never moves a name to the Auction stage and never raises an alert.
What happens if the name does not sell
Not every name sells at auction. Unsold names fall through to the ordinary public drop, on the usual schedule. The same watch carries over automatically: your availability and drop-imminent alerts take over, predict the release window, and tighten the checks into it. You never re-add the name, and you never have to choose between watching for the auction and watching for the drop. One watch covers both exits.
Where this fits
- Aftermarket monitoring is for names you already track. It is your watch list, extended across the resale market. See how aftermarket alerts work.
- Wantlists are the other direction: a saved search that surfaces names you have never seen the moment the market lists one that matches your criteria.
- Searching the aftermarket is browsing the whole market by hand, from the Aftermarket page in your dashboard, included on every plan.
Browsing the aftermarket is free on every plan. The alert on your own watched names is what a paid plan adds. See understanding plans and limits for the boundary.
