No return to my email

We attempt to answer emails within 48 business hours from the time we receive it.

We get many emails daily and unfortunately, there are some that go unanswered.  There are two main reasons for this.  First, we reply but receive a message the next day that the mail was undeliverable.  Attempts to resend the message is time consuming and is almost never successful.

The second is that our virus protection software identifies any suspicious incoming mail and immediately deletes it.  We also purposely delete emails in which the entire message is in an attachment
