I’m pleased to report that the results went better than expected. Within the first day and a half, over 95% of our clients responded that they received the initial test Statement from QuickBooks. The following week, a few more people replied that they were away on vacation and had received the test.
I also had two clients that I had incorrect email addresses for but once they were changed, everything worked. However, the final two clients that did not respond was not because they did not receive the email test, but because their replies did not get sent back to me.
It appears that these two clients are using Register.com as their email server and they are unable to email me since we have moved our email to 1and1.com.
(More to come about 1and1.com in the future)
