Digest emails are highly personalized based on the customer's account and activity. These emails are sent on a regular interval in an automated manner to send summary key information. Apart from being personalized, digests enable customers to save time and keep your brand on top of customers' minds.
Newsletters are yet another powerful medium to keep customers updated on a regular interval (generally monthly or bi-weekly). Companies combine the most important updates and sharable content assets in these newsletters. This helps your company engage with customers, improve content distribution, and build authority (when novel ideas are shared).
