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.
