Send to email accounts created solely for testing. All the big ISP’s offer free email accounts, so open one or two accounts per ISP. Sending to this list of addresses can provide insight into whether the message is going to the inbox, bulk folder, or is being filtered by the ISP. These test accounts are also an excellent way to check message rendering, and to verify that the message’s ‘call to action’ is above the scroll bar fold.
