Why is nobody opening your emails?

You wrote the email. You sent it to four hundred people who have all bought from you. Twelve of them opened it. It is a demoralizing result, and the usual advice, write better subject lines, is only occasionally the real problem.

Here is what actually drives low email open rates for a small business, in the order worth checking.

Why are my email open rates so low?

Low email open rates almost always come down to one of four things: your emails are landing in spam, your list has gone stale, you send too rarely for people to remember you, or your sender name and subject line do not tell people who you are. Check whether your email reaches the inbox first, because if it never arrives, nothing else you change matters.

For context, average open rates for small business email across most industries run roughly 20 to 35 percent, according to the benchmark reports published by the major email platforms. If you are seeing single digits, that is usually a delivery or list problem, not a writing problem.

Are your emails going to spam?

Emails from a small business most often land in spam because the sending domain is not authenticated. Three settings on your domain, called SPF, DKIM and DMARC, tell inbox providers your email genuinely comes from you. If they are missing or wrong, Gmail and Outlook treat your message as suspicious however good the content is.

Since 2024, Gmail and Yahoo have required authentication from bulk senders, so this is no longer optional. You can check your own domain for free with MXToolbox or Google Postmaster Tools, and most email platforms walk you through adding the records. It is usually a one time job of about an hour, and it is the single highest impact fix on this list.

The other common spam trigger is sending from a free address. An email from yourbusiness@gmail.com to four hundred people looks exactly like what a spammer does. Send from your own domain instead.

Is your email list too old?

A list that has not been emailed in six months or more will usually perform badly on the first send back, because addresses have gone dead, people have forgotten you, and inbox providers read a sudden burst to a cold list as suspicious.

The fix is unglamorous: clean the list. Remove addresses that have not opened anything in a year, fix obvious typos, and remove shared addresses like info@ and sales@ that nobody reads personally. If the list is genuinely old, send to your most recently active contacts first and widen out over a few sends rather than emailing everyone at once. A smaller list of people who want to hear from you beats a big quiet one every time.

Sending too rarely causes the same problem slowly. People who hear from you once a quarter forget they signed up and hit the spam button, which hurts delivery for everyone else on the list. Our post on how often to email your customers covers the right rhythm.

Do subject lines actually matter?

Subject lines matter, but less than the sender name. People decide whether to open based on who an email is from first and what it says second. If your sender name is a real person or a business name they recognize, you are most of the way there.

For the subject itself, specific beats clever. “Two openings this week and your winter checklist” outperforms “You won’t believe what we’ve been up to”. Keep it under about 50 characters so it is not cut off on a phone, where most email is now read, and skip the exclamation marks and capital letters that trip spam filters.

You can test this yourself for free. Most email platforms include subject line testing, which sends two versions to small slices of your list and sends the winner to the rest.

How do you fix low open rates yourself?

You can fix most low open rates yourself in an afternoon by working down the list in order: check your domain authentication with a free tool, switch to sending from your own domain, clean out addresses that have not opened in a year, set a regular sending rhythm, and use a sender name people recognize. Then watch the next three sends rather than judging one.

Quick answers

What is a good email open rate for a small business?

Roughly 20 to 35 percent across most small business industries, with local service businesses often at the higher end because the list is people who already bought. Under 10 percent usually points to a delivery or list problem rather than the content.

Why did my open rate suddenly drop?

A sudden drop usually means a delivery change: a domain record changed, you switched email platforms without setting authentication up again, or a large part of your list stopped engaging and providers began filtering you. Check authentication first.

Are open rates still accurate?

Less than they used to be. Apple Mail Privacy Protection loads images automatically, which inflates opens for anyone using Apple Mail. Click rate is now the more reliable sign that an email is working.

Should I buy an email list?

No. Bought lists are the fastest way to get your domain flagged, and emailing people who never agreed to hear from you can break anti spam rules. It damages the delivery of every future email you send.

Work down the list in order and the open rate usually sorts itself out. Once people are opening again, a simple email to bring past customers back is a good first send.
