If you're sending yourself (or your client) test campaigns from Benchmark Email, but you haven't received any of the emails, here's what to check:

• Was it actually sent? You are allowed to send up to 30 test emails per day per each campaign. If you've sent more than 30, chances are the email that didn't arrive was the 31st or 32nd, etc. If you send 30 emails a day for each campaign, Benchmark will not send the ones over that number.
  
  
• Was your email bounced back by your target's email server? After you send your email, give it a few minutes and then check your campaign stats for any bounces. If you see any, click to view the email headers, and try to find out why they bounced. The answer is often in the bounce headers. It could be that your email account was over quota, or your email server is just plain busy at the moment.
  
  
• Send test campaigns to as many "external" test accounts as possible (like to Yahoo!, Hotmail, Gmail, etc.). If you get the email at Yahoo! But not at Gmail, for instance, you'll know which email server has the problem. You may need to talk to your IT group about it. Your IT group may be banning all emails from outside servers (Benchmark included), especially ones that claim to come from your company (if your company's name is in the “from” field, for instance). They may also be using a super strict spam filter that blocks all email from outside sources, which means you may need to ask them to add Benchmark Email to their whitelist.
  
  
• If your Spam score is high your email could have been blocked by the anti-spam filter on the target email server.
