What it does

Wraps encodeURIComponent / decodeURIComponent. Useful for inspecting tracking URLs, building redirect URLs, or fixing broken email links.

When to use

Embedding query strings in email links. Debugging tracking-URL issues. Building UTM-tagged URLs by hand.

FAQ

Should I encode the whole URL or just parameter values?+

Just parameter values. Encoding the whole URL (including https://, ?, &) breaks the URL.

Converter ran. Now track what happens after you hit send.

Most senders convert formatting and move on. Outsolvi tracks what the recipient actually does with that converted email — opens (confidence-scored, not fake), clicks, replies, forwards. 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.
