Thanks for your input Valdis. Sometimes I need to send an email more than once to the same address because some customers have multiple accounts with us. So basically I'm using a mail merge email with their account number and invoice amount in the email. The thing is some of the same customers have seperate accounts and invoices with us. Therefore, I need to same another email to these same people but it has the other account number and invoice amount in the email. Also were do I check the MAXBSMTP value? Thank you in advance for your time. ----- Original Message ----- From: "Valdis Kletnieks" <[log in to unmask]> To: <[log in to unmask]> Sent: Tuesday, December 06, 2005 4:51 PM Subject: Re: Sending email to duplicate address's > On Tue, 06 Dec 2005 12:37:40 EST, Michael DeGregory said: > > I noticed that when sending a distribute job with Listserv to a relatively > > small list of people (under 1000) Listserv will send a seperate email to > > duplicate addresses in that list.
