UKNM: Dead email accounts

[aajgray]

Here's a question for y'all.  I've just finished a small email marketing

campaign for a client and the transmission reports make interesting reading.


The client is well used to what mail return rates to expect on DM but wants

to gauge the return rates on the email campaign (i.e. indicating what email

addresses have 'lapsed').


The best comparison I can think of is to take the 'unknown recipients'

results from the transmission report.  In this case, 7.5% of emails sent

were returned due to 'unknown recipient'.  Obviously, if one is using a work

address and then leaves, the address is deleted from the server in most

cases.


What I would like to know is at what point does this occur with free

Internet email addresses?  A user could switch from one free email account

to another and emails would just continue to pile up in the in-box without

an 'unkown recipient' response issued.  Do hotmail/ talk21/ yahoo etc. draw

the line when they see full email boxes and cancel the account?


Thanks,


Andy Gray
