Great and simple
Perfect, easily merged all my 4000 contacts in to 700 in a click. Backup file of the contacts is automatically made at the same time. A few clicks later I also got rid of a bunch of contacts without any contact information. The only weird thing I noticed is that every contact has got a text attached to them under “notes” that says (***** ***** ***** ***** *****) after I merged all my contacts. Why? 😅
