A travel or a promotion based recommendation is provided in association with a social graph of a recipient of a communication. A communication service initiates operations to provide the travel or promotion based recommendation by processing a content of a communication to identify a travel plan of a recipient or a promotion directed to a recipient. A detected shared attribute between the travel plan of the recipient and the travel plan of the acquaintance is assigned a relevancy score. The promotion is processed to determine a trend of the promotion with an acquaintance at a social networking site and an accuracy of the promotion. The shared attribute or the promotion is provided to the recipient.
