Email List Sorter

The Email List Sorter arranges a messy collection of addresses into a tidy, ordered list using the sort key you choose. Sort straight alphabetically by the whole address, group contacts by their domain so everyone at the same company sits together, or order by username to line up similar local parts. Each mode can run ascending or descending, giving you full control over how the final list reads.

Ordering a list is a small step that pays off constantly. Sorting by domain instantly clusters colleagues from the same organisation, which is perfect for account-based outreach or spotting how many contacts you have per company. Alphabetical sorting makes a list easy to scan and compare, and a descending order can bring the tail end of the alphabet or the least common domains to the top for review.

Everything runs locally in your browser using JavaScript, with no upload and no account. Paste or upload your addresses, pick a sort key and direction, optionally deduplicate and lowercase in the same pass, then copy or export the ordered result. Because your data never leaves your device, even confidential contact lists stay completely private while you organise them.

Features

• Sorts by full email address, by domain, or by username so you can organise the list the way you need.
• Supports both ascending and descending order for every sort key with a single option.
• Groups contacts from the same company together when you sort by domain for account-based work.
• Offers optional duplicate removal so the ordered output contains each address only once.
• Provides optional lowercasing to normalise capitalisation before sorting and deduplicating.
• Extracts addresses from surrounding text, so raw pasted content is sorted without pre-cleaning.
• Exports the ordered list to TXT or CSV, or copies it to the clipboard in a single click.

How to use Email List Sorter

1. Paste your email addresses into the input box, or upload a .txt or .csv file from your device.
2. Choose a sort key: by full email, by domain, or by username of the local part.
3. Pick ascending or descending order to control the direction of the sort.
4. Optionally enable remove duplicates and lowercase to tidy the list in the same pass.
5. Click the Sort emails button to produce the ordered, one-per-line list.
6. Copy the result to your clipboard, or export it as a TXT or CSV file for later use.

Benefits

• Clusters same-company contacts together when sorting by domain, ideal for account-based outreach.
• Makes long lists easy to scan, compare, and spot-check by putting them in a predictable order.
• Combines sorting, deduplication, and lowercasing so you tidy a list in one quick step.
• Speeds up manual review by letting you flip between ascending and descending order instantly.
• Keeps confidential lists private because all sorting happens in your browser only.
• Produces clean, ordered output that pastes neatly into any spreadsheet, CRM, or sending tool.

Choosing the right sort key depends on your goal. Sort by domain when you want to see everyone from the same organisation together, which is the fastest way to identify key accounts and plan targeted outreach. Sort by username when you are comparing local-part naming conventions, and sort by the full address when you simply want a clean, scannable, alphabetised list for review or archiving.

The optional lowercase and deduplicate steps run before the final sort, so enabling both gives you a normalised, repeat-free, ordered list in a single pass. All comparisons are case-insensitive so that mixed capitalisation does not scatter otherwise identical entries. For a fuller cleanup with format validation, follow up with the Email List Cleaner, and use the Email Domain Counter if you want per-domain totals rather than a sorted list.
