Like so many things, “When is the best day of the week to post?” depends on your audience. Not all fields of business are the same. That said, I’ll share with you the things I’ve learned over the years as they relate to my field and audience.
No, I’m not talking about dreading going to work or school. What I’m referring to is the fact that Mondays are bad days to send out email newsletters (or blog posts that go to email, such as via RSS feeders), especially if it’s something the recipients are paying for. Why are Mondays bad? It’s the day a subscriber is most likely to remove himself from your list. Why would a reader do that?
Most people are more aware of their financial situation on Mondays than on other days of the week. You might think it would be on Fridays—when they get paid—but no, it’s on Monday, after they’ve been spending money all weekend and they come back to reality and see the stack of bills. (If this is you, you’re not alone!)
If they get an email from you when they’re stressing about money, they’re much more likely to cancel their subscription, because they are reminded that they are spending money on what they’re receiving from you, and they just realized they shouldn’t be spending money. They’re also much less likely to buy anything offered in those emails if it’s a Monday when they see it, for the same reason.
You can’t control when they see it, of course. You could send out a missive on a Thursday and some people won’t see it until the following Monday (if they manage to see it on the previous Monday, send them my way, because I want some of their time-traveling ability. There’s something in 1976 I’d like to change).
What is the best day to post?
You definitely can’t control every factor. Just do what you can with the ones you can have some control over—just like anything else in life. You can make it less likely that most readers will see it on a Monday by not posting it on a Monday. Now, if your niche is comedy or stress-relief, or personal finances, for example, then you may very well want to post on a Monday.
Just give some thought to your audience and what the members of it might be thinking and feeling on a certain day of the week, and experiment. You might even ask your readers. For most of my steady readers, Wednesday is the day they could use some encouragement to keep going to the end of the week, so Wednesday is the day the posts go out. For your readers, it might be Fridays. Do what works best for your audience.
