+
+We have successfully imported the accounts that were mis-generated, but they will no longer be recovered with your normal seed phrase.
+
+We have marked the affected accounts as "Loose", and recommend you transfer ether and tokens away from those accounts, or export & back them up elsewhere.
+
+Your affected accounts are:
+${lostAccounts.map(acct => ` - ${summary(acct)}`).join('\n')}
+
+These accounts have been marked as "Loose" so they will be easy to recognize in the account list.
+
+For more information, please read [our blog post.][1]
