How Often Should a Small Business Send Marketing Emails?

If you search "how often should I email my customers," you'll get answers from companies that make more money when you send more emails. MailChimp, Constant Contact, HubSpot — they all have a financial incentive to tell you to send more. More sends means more usage, which means higher-tier plans.

So let's skip the self-serving advice and look at what actually works for small brick-and-mortar businesses — the coffee shops, salons, restaurants, and boutiques that make up most of our economy but get ignored by most marketing advice.

The honest answer: most small businesses should be sending once a week to once every two weeks. That's it. No complicated automation sequences. No 47-email nurture funnels. Just consistent, useful communication with people who already like your business.

Here's the thing that most "email marketing experts" won't tell you: email is already working for businesses like yours, and you don't need to overthink it. A recent study found that 44% of small businesses report email as their most effective marketing channel — beating social media, paid ads, and SEO. And those businesses aren't sending emails every day. Most are sending a handful per month.

Across all industries, the average email open rate sits around 36.5% with a 1.4% click-through rate. Those are strong numbers. Compare that to social media, where organic reach on Instagram hovers around 5-7% and Facebook is even worse. Your emails are getting seen.

What about your customers — how often do they actually want to hear from you? The data here is clear: 61% of consumers say they prefer to receive promotional emails on a weekly basis. Not daily. Not "whenever you have something to say." Weekly. That's the frequency where people feel informed without feeling spammed.

The sweet spot for most small businesses lands between 4 to 8 emails per month. That gives you enough runway to stay top-of-mind, share what's new, run the occasional promotion, and still leave your customers looking forward to your next message instead of dreading it.

Not every business is the same, and your ideal frequency depends on what you sell and how often your customers need it. Here's a breakdown based on industry data and real-world performance:

Every business is different, and these are starting points — not rules carved in stone. When you sign up for Cherub, it adapts to your specific industry and business type automatically. You tell us what you do, and the AI calibrates your sending frequency, content style, and timing from day one. No research required on your end.

Your customers won't always tell you directly that you're emailing too much. But there are signals — and a good email platform should be watching them for you so you don't have to. Here's what's happening behind the scenes:

Engagement drops off. When subscribers start ignoring your emails — not opening, not clicking — it damages your sender reputation with email providers like Gmail and Yahoo. That means even the people who do want to hear from you start getting your emails in spam. This is a technical problem, not a creative one, and it's something your email platform should be catching and adjusting for automatically.

Unsubscribes creep up. Some unsubscribes are normal and healthy — you want a clean list. But a rising unsubscribe rate usually means frequency is too high or the content isn't relevant enough for the pace you're setting. The fix isn't to obsess over a percentage — it's to send fewer, better emails.

Spam complaints appear. This is the most serious signal. When someone marks your email as spam instead of just unsubscribing, it directly hurts your ability to reach everyone else's inbox. Even a handful per send means something needs to change.

Here's the thing: you shouldn't have to watch any of these numbers yourself. This is exactly the kind of work that should be automated. At Cherub, we monitor deliverability signals behind the scenes and adjust your sending cadence accordingly — so you can focus on running your business, not staring at dashboards full of vanity metrics.

Here's the counterintuitive part: not emailing enough is actually riskier than emailing too much. The damage just happens more quietly.

Your domain reputation decays. Email providers like Gmail track your sending patterns. If you send regularly, they learn to trust your emails and deliver them to the inbox. If you go quiet for weeks and then blast out an email to your whole list, Gmail sees that as suspicious behavior — it looks like a compromised account or a spammer warming up. The result? More of your emails end up in spam, even though you're a legitimate business.

Your email addresses go stale. This one shocks most business owners: roughly 22.5% of email addresses become invalid every year. People change jobs, switch providers, abandon old accounts. If you're only emailing your list a few times a year, you're sending to a list that's literally rotting. And sending to invalid addresses hurts your deliverability for the valid ones.

Subscribers forget they opted in. If someone signed up for your email list six months ago and hasn't heard from you since, they won't recognize your name in their inbox. They won't think "Oh, that's the nice salon I visited last summer." They'll think "Who is this?" and hit the spam button. The longer you wait between emails, the higher your spam complaint rate will be when you finally do send.

This is one of the biggest reasons we built Cherub to maintain a consistent cadence for you automatically. Even when you're busy — especially when you're busy — your customers keep hearing from you. Cherub also sends proactive campaign suggestions based on weather changes, upcoming holidays, and seasonal patterns for your industry, so you're never starting from a blank page wondering what to send.

If there's one takeaway from this entire article, it's this: inconsistent sending is worse than infrequent sending.

Email providers — Gmail, Yahoo, Outlook — use your sending patterns to decide whether to deliver your emails to the inbox or the spam folder. They're looking for consistency. A business that sends one email every Tuesday looks trustworthy. A business that sends nothing for three weeks and then fires off five emails in two days looks suspicious.

The minimum cadence you should maintain is one email per month. That's the floor. Below that, your domain reputation starts to erode and your list starts to decay. But whatever frequency you choose — weekly, bi-weekly, or monthly — the key is sticking to it.

Pick a schedule you can actually maintain. It's far better to commit to two emails a month and never miss than to aim for weekly and go silent every time things get busy. Your customers (and your email deliverability) will reward the predictability.

This is exactly why we built Cherub to handle scheduling for you. The AI keeps your cadence steady, suggests campaigns at the right times, and all you have to do is approve them. No editorial calendar to maintain, no guilt when life gets hectic. Your emails just keep going out.
