Why Is In-Inbox Email Capture Superior to External Landing Pages?

Asking users to leave Instagram, open a browser, and fill out a multi-field web form causes 70%+ lead drop-off. In contrast, asking for an email address inside an active DM conversation feels natural, yielding significantly higher opt-in conversion rates.
