Recently I sent an email to a customer who is using yahoo’s email service. But it seems he didn’t get it. Then I sent it again. He still didn’t get it.
So I have to doubt if his spam filter blocks my email. But I have no way to contact him except email. So I have to try to send him from all my possible email accounts. God bless the email can be passed to him this time. I am hoping him not to be surpised if several of the same email get into his email box.
Spam filter is not a perfect program. I guess sometime you may have to check the spam box if you are waiting for an important email.
