how do i process all AGOL features at once instead of one by one?

new to FME so i apologize for the elementary question, but is there a way for me to bring in all features within a feature service at once so that i can process them with a python caller? i need to run counts and reference external csv files on the data and i can't do it properly without having all of the records.

for example, if i wanted to send an email that contained a list of all employee names within a feature layer, how would i do that? currently its sending an email for every employee within the feature layer (100 employees = 100 emails) i need 1 email that contains 100 employee names.
