A saved search keeps a set of filters so you can run it again with one click, and can mail you the new matches every day. Start by running any search, for example every domain with a Domain Authority of at least 30 and a Majestic Trust Flow of at least 15.
Save the search
Press Save Search in the button bar above the table. Give the search a name you will recognise in a list, and choose whether you want a daily e-mail with the domains that newly match it. Press Save Search.

Run it again
Your saved searches appear in the My Searches menu at the top of every page; pick one and the table reloads with its filters. The search remembers which list it was made in (Expiring, Expired or Archived).
The My Searches page, at the bottom of that menu, lists them all. There you can put searches into groups, switch the daily e-mails on or off for several at once, and delete the ones you no longer need.
The daily e-mail
All your searches with the daily e-mail switched on go into one message, sent each morning after the night's lists are built. It contains the domains that matched since the previous day, with the same columns you see in the table, and a star next to each domain that adds it to your WatchList with one click.
Tip: tick Load this search every time I visit above the search panel and the table opens with that search already applied whenever you log in.
