Educate & EngageAbout this email
This email announces an enhanced feature in Hunter's Domain Search, focusing on more precise targeting of decision maker email addresses grouped by department and relevance. It explains the previous limitation, introduces the new functionality with bullet points, and invites the recipient to start using the update or read a product blog for help. The tone is informative and professional, supported by clear calls to action and social media links for engagement.
Hunter.io journey
Why this works
**Why this works.** The subject line frames the update as a resource optimization problem ("make your free Search Credits go further") rather than a feature announcement, so free-tier users immediately see personal ROI instead of skipping past another product changelog. The pattern here is "benefit before feature name"; you can lift it for any product update email where your lowest-tier users need to understand what's in it for them before they care what changed.
