But after I update to 8.4.7, I got big problem.
I sent about 3 thousands of promotion mails to our customers.
It took long time but we succeeded.
*setting -> Delivery Singly, Group mails:5
After that we got hundreds of complaint mails from customers about their name.
They said "I'm not XXXX" something like that.
We used "TAG" like "Dear XXXX(First Name)" and I checked preview before I sent.
At that time we had not any problems.
But, the name was mixed up, almost everybody!
And somebody said if forward or reply the message, they can see another persons name and e-mail address.
Just few people noticed but I think everybody can see it .
Wrong name and include wrong address, such a big problem and we got big damages!
Why it happen?
We use this program for long time but never have had this kind of problems before.
I'm preoccupied with responses to recovering and exhausted.
If you have some ideas please let me know.

We sent to Susanne, but the name is Grace and the address is Grace's address.
Thank you.
