Emailing Frequency is a question that vexes many content-marketers. As with most such question in life, there’s no simple answer to this seemingly straightforward question. The answer you get would be “Depends on your niche, how engaged your newsletter subscribers are, and your own trial-and-error experiences”. The problem that usually arises with sending out Email Marketing Content, is that you may make some wrong assumptions, and take “corrective actions” based on those assumptions – which compounds your problems.
For example, when you begin to see that disengagement makes people leave your email unopened, you quickly anticipate this as a “potential unsubscribe”. You then begin to think subscriber interest is going downhill because of your emailing frequency … and that the disinterest is being exacerbated because you are emailing too often. However, experts in Email Marketing would tell you this sort of logic is fallacious. A lot of people (the majority, in fact) subscribe to get some lead magnet – and then have no further interest in the business that gave them the lead magnet. They don’t automatically anticipate building a relationship with you (which you assume they’re ready to do, just because they gave you their email). The truth is getting their email addresses is your first step. After that it’s up to you to try and build a relationship with those who subscribed. People have to be nurtured into a emails-ready relationship. It doesn’t happen automatically, when they give you an email address!
