Tabbloid can aggregate multiple RSS Feeds, convert them into PDFS, and Email them to the user. There is no need to register, users just add the RSS Feed they want to subscribe to and their own Email, and set the frequency and time of sending. Unfortunately, it is another network service that does not support Chinese, and unsubscribing seems to be a problem.
However, Tabbloid can be very useful when the network is limited to Email services. Wheat Ant has previously introduced seven very useful Email application services.
