Email Preview Text Analyzer

Analyzes the preview text that appears in inbox snippets after the subject line. Length, repetition with subject, hook quality.

Length: 98 characters (too long. gets truncated)
Subject-line overlap: 0 words (good. preview adds new context)

You analyzed one send. Outsolvi analyzes every send, forever.

Subject scores, preview tests, header parses are one-shot. Outsolvi runs the same analysis on every email you send and surfaces patterns: which subjects open, which preheaders convert, which threads stall. From $7/user/mo yearly.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi runs Tier 1 to 5 confidence scoring on every open, native in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
