I sent weekly emails. My open rates dropped.Then I stopped guessing.
I was sending newsletters every Thursday like clockwork, convinced that consistency meant frequency. The opens stayed flat around 18%, and I kept thinking more emails would build habit. It didn't. What changed was actually measuring what my audience responded to, not what felt right to me.
I started tracking which send days got opens, which subject lines people actually clicked, and how many days between sends before people started unsubscribing. HubSpot's research on email frequency shows most small businesses see better engagement with 1-2 sends per week than daily blasts, but the real number depends on your list. Some audiences want weekly deep dives. Others prefer twice-monthly roundups. The only way to know is to test your own data, not copy what feels standard.
What I found is this: the best frequency is the one where your unsubscribe rate stays flat and your opens hold steady. That's different for every business. Our content marketing approach focuses on matching send frequency to actual audience behavior, not industry averages.
Pick a frequency (weekly, biweekly, or twice weekly), stick with it for 4 weeks, then check your open rate and unsubscribe rate. If both are stable or climbing, you've found your rhythm. If unsubscribes spike, dial it back.
