Look for all email marketers out there DO NOT make the mistake of having your subject line disconnected from your marketing message just to get the email opened because you are making a big mistake.
Getting your email opened is only 25% of the battle. You still need the reader to click on your link and pay attention to your marketing message on your website. If you mislead people with your subject line then you have no chance in hell of getting them to take any further action.
All that happens is the reader gets frustrated and feels mislead and lied to so they unsubscribe or at the very least never pay attention to your email again.
Keep your subject line in line with your marketing message. If the subject line fails to have a good open rate then you must test other options including taking a look at your marketing message, maybe that has to ultimately change.
After receiving these kinds of subject lines from various people I'm inclined to think someone out there is teaching this. If it's you that are teaching others to use misleading subject lines like this then shame on you... you are doing a huge disservice to your clients.
To the clients who have been taught to do this... take your money and run from this type of mentor and save yourself from ruining or discrediting your business.
