Reader Bob Nixon is about to make a major life change and he’d like a helping hand. He writes:
I’m about to change ISPs, I think. What’s holding me back is the thought of having to collect all the (possibly) hundreds of addresses of the people and organizations who have used my current email address lo these many years.
Are you aware of a utility that will do the task for me? That is round up all the unique addresses in my Inbox/Sent box in Mail without duplicates?
I am. Take a look at Limit Point Software’s donation-ware
MailCM. Among other things, with this plug-in/preference pane combo you can select all the messages in a Mail mailbox, right-click on the selected messages, and choose Add to Address Book. Doing so creates a group within Apple’s Address Book marked MailCM date and time, (where date and time is the date and time you created this group) that contains all the From contacts within those selected messages. And yes, it filters out duplicate addresses.
I used it to import nearly 1,300 addresses from around 4,200 selected messages in Mail and it took a couple of minutes to complete the job. Definitely worth checking out.
