HEY is an email product from Basecamp and their headline "We finally fixed your email + calendar!" is quite the attention-grabbing and bold message. In the crowded spaces of both email and calendar apps, stopping the scroll with a solid H1 is crucial.

The use of "finally" suggests that email and calendar problems have been a long-standing issue that all of the other options have failed to solve. It implies that HEY has finally cracked the code.

I'm not usually a fan of exclamation points in headlines… but here it adds a layer of enthusiasm and confidence to their bold claim.

"Fixed" is another powerful word choice. It implies that current email and calendar systems are broken and that Hey has actually solved the underlying problems rather than just making incremental improvements.

By saying "your email + calendar," the headline makes it personal to each reader. It's not just fixing email and calendar systems in general - it's fixing YOUR specific problems with these tools.

This addition of calendar alongside email shows that HEY understands just how interconnected these tools are in most people's work lives. This suggests a more comprehensive solution rather than just another email client (which always seem to get acquired and shut down).

Overall, this headline is effective because it directly addresses widespread frustration with existing email and calendar tools while confidently claiming to have solved these issues. The personal address and enthusiastic tone make the message more engaging while the boldness of the claim encourages users to learn more about how HEY has achieved this fix.

If you're one of the many who have first-hand frustrations with email or calendar management… this headline likely grabbed your attention and stopped your scroll.
