Email Sorter — Sort by Name, Domain, Length or Frequency

Why sort an email list at all

Sorted lists are reviewable lists. Alphabetical order makes typos jump out (gmial.com sits apart from gmail.com), domain grouping clusters every address from one company for manual approval, length ordering surfaces truncated or concatenated entries, and frequency ranking exposes the noisiest repeat signups in merged datasets. Unsorted 10k-line dumps hide all of that in noise.

Sorting also makes outputs deterministic: the same input always yields byte-identical output, so diffs between runs, version control and compliance reviews stay meaningful instead of reflecting random row order from whichever export ran last.

Four sort axes and when each wins

Alphabetical (A–Z or Z–A) is the default for human review and dedupe verification. Domain mode clusters by company with alphabetical order inside each cluster — the fastest way to eyeball per-account coverage. Length mode (shortest or longest first) is a data-quality scan: suspiciously short entries are often fragments, suspiciously long ones concatenated cells. Occurrence mode ranks by how often each address appeared, spotlighting bot resubmissions and sync artifacts.

All modes are stable: equal keys keep their input order and ties break deterministically by value. Ascending versus descending is a presentation choice with one exception — frequency ranking is usually read descending, noisiest first.

• Alphabetical → general review, typo hunting, sharing
• Domain → B2B review, per-company approval, account mapping
• Length → fragment and concatenation detection
• Occurrences → bot, resubmission and sync-artifact forensics

Sort without destroying information

Sort after dedupe, not before: merging first means the surviving order is first-seen chronology, and the subsequent sort is a pure presentation layer over clean data. Keep a copy of the unsorted deduped list when signup order matters for analytics, and treat the sorted export as the review artifact.

Combine with the lowercase and dedupe toggles for canonical output — lowercased, deduplicated, deterministically ordered lists diff cleanly across weeks, which is exactly what auditors and compliance reviews want to see.

Sorting at scale, privately

Sorting runs in the same local Web Worker as extraction, so even large lists order without blocking the page and without transmitting anything. Paste, choose the axis and direction, export TXT for sharing or CSV with the domain column when the sorted order needs to survive a spreadsheet round-trip.
