Although email newsletters seem simple enough, for them work properly you need to have some knowledge of what not to do. 

Just some of the common mistakes:

• Not having permission
• Confusing transactional emails with email marketing
• Assuming people will remember who you are
• Writing like a used-car sales man
• Ignoring campaign reports
• Sending with a personal reply-to email address

I would like to point out quickly that if you are sending out an email newsletter already but you don't have reports/statistics of your success rate then you really need to rethink what you are using to send them. Reports & statistics are what matters, how can you improve if you don't know what works and what doesn't.

If all else fails, or this seems just to hard, let us handle it for you. We know tons of little tips to make sure you newsletter gets opened.
