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. Opens stayed flat around 18%, and I kept thinking more emails would build the 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 clicked, and how many days between sends before unsubscribes ticked up. HubSpot's research on email frequency shows most small businesses see better engagement with one or two sends a 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 your own data, not what feels standard.
Here's what I found: 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 matches send frequency to actual audience behavior, not industry averages.
Pick a frequency, weekly, biweekly, or twice weekly, and hold it for four weeks, then check open rate and unsubscribe rate together. Stable or climbing on both means you found your rhythm. If unsubscribes spike, dial it back. Let your data set the cadence.
