Compare Two Email Lists
Find which addresses are new, removed, or shared between two lists.
— no items —
💡 Paste a list in each box (one item per line). Only in A = items missing from B · In both = the overlap · Only in B = items missing from A · All (unique) = combined, de-duplicated. Everything runs in your browser.
email lists tips
"Only in A" finds subscribers who unsubscribed; "Only in B" finds new sign-ups since the last export.
Turn on "Ignore case" so Bob@x.com and bob@x.com are treated as the same address.
"In both" shows who's on both lists — useful for de-duplicating before a send.
Email lists are compared in your browser — never uploaded.
