Setting up email alerts with PubMed has just a few steps:
In order to create an alert, you must be signed in to your free My NCBI account. Find the "Sign in to MyNCBI" link at the top right of the PubMed homepage to sign in, or to register for a new account.
Perform a search on a topic for which you would like to set up an alert.
From the Results screen, click “Create alert,” below the search box.
"Your saved search” menu will appear at the top of your search results. The saved search is automatically named; you can change this to a more meaningful name.
Notice the option “Would you like e-mail updates of new search results?” Select Yes. Scroll down to see more options, including how frequently you would like new results sent to you; how many results you would like to receive, at most; and whether you would like to receive an e-mail even when there are no new results.
Once you have made all your selections, click the blue “Save” button at the bottom.
