If the budget allows, I’d run a paid ad featuring a short, relatable video that highlights common email frustrations (overflowing inboxes, lost messages, etc.), followed by how Extra solves the problem. I’d end with a clear CTA to motivate viewers to take action and sign up for the waitlist.

To grow Extra on TikTok, I’d leverage creative, shareable content that showcases the app’s value in a fun, relatable way. I’d focus on trend-driven content, entertaining videos, community engagement, and consistent posting/testing. Success would be measured by follower growth, engagement rates, video views, and waitlist sign-ups driven from TikTok content.
