1) While email marketing drives nearly half of online purchases, consumers say email only moderately increases purchase likelihood. Email is seen as a reminder of existing brand affinity rather than a driver of new purchases.
2) Consumers are more likely to "like" or follow brands on Facebook and Twitter for social and interest-based reasons rather than purchase influence. These actions increase overall brand affinity and trust more than directly influencing purchases.
3) Direct marketing channels like email and voucher sites have a stronger influence on actual purchases compared to social media. However, social media better increases brand recommendation and overall likelihood to buy in the future through growing affinity and trust.
