A lot of my emails to my opt-in list were ending up in spam folders. These are emails sent through Constant Contact and also Aweber. I'm a pretty thorough guy when it comes to figuring out causes, and I learned something that might affect some of you (not many, but possibly some), so I'm passing it along.
One of the spam triggers is having too many consecutive consonants in your 'From' and/or 'Reply To' email addresses in the header of your outgoing emails. Seems this is a common tactic used by spammers who make up bogus email addresses. They use things like: email@example.com
Well, lucky me. My name is John Schwartz and my email is: firstname.lastname@example.org. See all those consonants in a row? Yep. It was making my outgoing emails a lot more likely to trip spam filters.
So, I've fixed that problem. Haven't tested to see if it makes any difference, but I figured it might apply to some of you guys and gals, so wanted to pass it along.
