Donaldson R F Sort Email List
Put a list of email addresses in order — alphabetically, by domain, or by length.

How it works
Sorting ignores upper and lower case, so alice@x.com and Bob@x.com sort by their letters, not by capitals. By domain groups all the addresses from the same domain together (a.com before b.com), which is handy for spotting large organisations; within a domain they are sorted by the part before the @. Ties keep their original order.

Frequently asked questions
Does it change the addresses?
No. Only the order changes (and duplicates are removed if you tick the box).
Why is a name with a capital letter not first?
Capitals are ignored when sorting so the order is what people expect.
Is my list private?
Yes. It never leaves your browser.
