Yes. Here are the rules:

Like I said, there are some drawbacks to what NCBI has published, but
the eutils_help.html web page is fairly clear.   The 'email' and 'tool'
arguments do not effect the retrieval, but are there to help NCBI either
(a) notice which programs are generating Entrez queries to help them do
query optimization, or (b) for them to contact you if there are problems
or they are changing interfaces that might effect your requests.
