Feature announcement: more useful weekly account digests

The latest update from Postmark brings a fresh design and additional features to their weekly account digests. Starting next week, users will receive a new look with improved statistics displays for outbound/inbound activity, bounces, and deliverability recommendations. The updates aim to provide users with a better overview of their account health and actionable steps to improve email delivery. Key changes include color-coded stats, warnings for high spam rates, and a checklist of tasks to enhance deliverability. The digests will also feature recent blog posts and product updates at the bottom.
