Email Open Rate: How to Get Local Customers to Open Your Emails

Email open rate is the percentage of delivered emails that were opened: unique opens divided by emails delivered, times 100. Two hundred opens from a thousand delivered emails is a 20% open rate. Klaviyo’s 2026 analysis of more than 205,000 brands puts the average campaign open rate at 31%, and 31.2% for food and beverage senders specifically.

There is a catch you need before you read another benchmark. Litmus, which measures over a billion opens, reports that more than half of all email opens now happen on a device with Apple’s Mail Privacy Protection turned on, and MPP loads the tracking pixel on Apple’s schedule whether or not a human ever looked at the message. Your reported open rate is therefore inflated, and unevenly so across your list.

That does not make open rate useless. It makes it a comparison tool rather than a score. Within the same list, in the same week, a subject line that beats another by six points did beat it. What you cannot do is treat 34% as proof that a third of your customers read your email.

This post covers everything that happens before the click: sender name, subject line, preview text, timing and segmentation. For what to do once someone is inside the email, see email click-through rate; if opens fell suddenly, check email bounce rate first, because deliverability problems look exactly like subject line problems. The full metrics scorecard shows how opens sit alongside the other five numbers.

The Bottom Line

• Open rate = unique opens ÷ emails delivered × 100. Klaviyo’s 2026 cross-industry average is 31%, with the top 10% of senders at 45.1%.
• More than half of opens come from devices with Apple Mail Privacy Protection active, per Litmus, so the number is inflated. Use it for A/B comparison, not as an absolute.
• The sender name does more work than the subject line. People open mail from businesses they recognise.
• Tuesday to Thursday, 9-11am local time, performs best for opens; later evening sends tend to earn more clicks and orders.
• Send timing should follow your order cutoff, not a generic benchmark. If Thursday deliveries close Wednesday noon, the email that matters lands Tuesday morning.
• A shrinking open rate on a growing list usually means the list is getting staler, not that your writing got worse.

What counts as a good email open rate in 2026

Benchmarks differ by source because each platform measures its own customers.

Sources: Klaviyo email marketing benchmarks and Mailchimp email marketing benchmarks.

Practically, 25-35% is normal territory for a small sender with a list built from real customers. Above 40% usually means either a small, highly engaged list or a heavy Apple Mail audience inflating the count. Below 15% means something structural is wrong: stale addresses, spam-folder placement, or a sender name nobody recognises.

Automated emails sit far above campaigns on every benchmark, and welcome emails sit highest of all, because they arrive while the person still remembers signing up.

What the sender name does that the subject line cannot

Before anyone reads your subject line, they read who sent it. In a crowded phone inbox that recognition decides most opens, and it is the easiest thing on this list to fix.

Send from your business name, spelled the way customers know it, and keep it identical on every send. “Rosewood Bakery” beats “Rosewood Bakery Marketing Team”, and both beat “noreply@”. If a person at your company has the relationship, such as the account manager your wholesale buyers actually talk to, “Marta at Rosewood Bakery” outperforms either.

Use a real, monitored reply address. Customers reply to availability emails with orders and questions, and a no-reply address throws away revenue and tells mailbox providers you are a bulk sender rather than a correspondent.

Then leave it alone. Changing the sender name every few months resets the recognition you built and can push you into spam folders.

How to write subject lines your customers actually open

A few patterns hold up consistently for local businesses selling perishable or made-to-order goods.

Be specific about what is available. “This week: heirloom tomatoes, sourdough back on Thursday” beats “Our weekly newsletter”. Specificity is a promise the email can keep, which protects your click-to-open rate too.

Keep it short enough to survive a phone. Roughly 40 characters is what shows on most mobile screens. Put the meaningful word first, because the end may be cut.

Use the deadline you already have. An order cutoff is urgency you do not have to invent. “Wednesday noon cutoff for Thursday delivery” works because your customers already operate on that clock, and it never feels manufactured.

Skip the tricks. “Re:” on a first contact, false “you forgot something” hooks and fake personal subjects earn one open and lose the relationship. They also attract spam complaints, which cost you far more than one campaign’s opens.

Write the preview text on purpose. The 35-90 characters after the subject line are prime real estate that most senders waste on “View this email in your browser”. Use it to extend the subject rather than repeat it.

Personalise with something useful. A first name is weak. What the customer last ordered, or their delivery day, is strong, and it requires only that your platform can segment on order history.

The best time to send marketing emails

Aggregate data lands in a consistent place: Tuesday through Thursday, 9-11am in the recipient’s local time, produces the strongest opens, with Tuesday generally leading. Later sends, roughly 5-9pm, tend to earn more clicks and conversions because there is less competition in the inbox and more leisure time to act.

But aggregate data is the wrong clock for a delivery business. Your send time should follow your operation:

• Work backwards from the order cutoff. If Thursday’s route closes for orders Wednesday at noon, your availability email needs to land Tuesday morning, early enough that a buyer can check stock, ask a question, and still make the cutoff.
• Reach wholesale buyers before their day starts. Restaurant and cafe buyers do their ordering early. A 6-7am Tuesday send often outperforms the 10am benchmark for that segment.
• Reach retail customers in the evening. Household customers plan weekend meals and flowers in the evening, not during the workday.
• Respect the seasonal rhythm. Valentine’s Day for a florist and the fortnight before Thanksgiving for a caterer have their own calendars, and generic best-time advice does not apply.

Test it on your own list. Send the same email to two halves of a segment at different times for four weeks running, and you will have an answer specific to your customers, which is worth more than any published average.

Segmentation does more for open rate than better writing

The most reliable open-rate gain available to a small sender is mailing fewer people more relevantly.

Split your list by what the customer actually is. Wholesale accounts and retail customers have different needs, different order cycles and different vocabulary. Then split by behaviour: customers who ordered in the last 30 days, customers who have lapsed, and subscribers who have never ordered at all. Add delivery day if your routes are fixed, since a Tuesday-route customer does not need a Friday availability email.

Two rules make segmentation pay:

• Stop mailing the unengaged. Anyone who has not opened anything in six months is dragging your averages down and raising your complaint risk. Try one plain re-engagement email: “still want to hear from us?”, then remove the non-responders. Open rate on the remaining list rises immediately, and so does deliverability.
• Match frequency to the segment. Weekly is right for a restaurant buyer who orders weekly. It is too much for a retail customer who buys once a month, and too little for the subscriber who signed up two days ago.

Why your open rate dropped

Work through these in order, because the first two are far more common than the last.

1. Mail stopped arriving. Check bounce rate and spam complaints. A drop across every segment at once, with content unchanged, is almost always deliverability.
2. Mail arrived but not in the inbox. If bounces are flat and opens fell anyway, you may be landing in Promotions or spam. Keep test accounts on Gmail, Outlook and Yahoo, include them in every send, and look at where the message actually went.
3. The list aged. Business addresses turn over constantly. A list you have not cleaned in a year contains a meaningful share of dead and abandoned mailboxes that still count in your denominator.
4. You sent more often. Frequency increases suppress open rate per send even when total engagement rises. Judge the month, not the message.
5. Apple changed something. MPP-driven opens move when Apple changes how it prefetches, and that shows up as a step change in your reporting with no cause on your end. It is one more reason to trust clicks.
6. The subject lines got vaguer. Real, but last on the list. Check the five causes above before rewriting anything.

What to track instead of open rate

Since open rate is inflated, pair it with metrics a machine cannot fake.

Click-to-open rate, clicks divided by opens, is the honest content read. Averages sit near 6-7%, and strong campaigns reach 10-15%.

Click rate on delivered emails is the trustworthy engagement number, because a click needs a human.

Conversion or placed-order rate is what actually pays for the send.

Revenue per email lets you compare a discount campaign with a full-price availability list on the same scale.

Keep reporting open rate, but use it the way it still works: two subject lines, same list, same week, and the winner takes the next campaign.

Frequently asked questions about email open rate

What is a good open rate for email in 2026? 25-35% for most senders. Klaviyo reports 31% across industries and 31.2% for food and beverage, with the top 10% of senders at 45.1%.

How is email open rate calculated? Unique opens divided by emails delivered, times 100. Bounced emails are excluded from the denominator, which is why your open rate and your bounce rate move together.

Is open rate still accurate? No. Litmus reports that more than half of opens come from devices with Apple Mail Privacy Protection enabled, which loads tracking pixels automatically. Use open rate for comparison within your own list, not as an absolute measure.

What is the best day to send marketing emails? Tuesday through Thursday for most senders, with Tuesday often strongest. For a delivery business, the better rule is to send far enough ahead of your order cutoff for a customer to act.

How long should a subject line be? Around 40 characters, so it survives a mobile screen, with the important word first.

Does a low open rate hurt deliverability? Yes. Mailbox providers treat engagement as a quality signal, so persistently low opens make it harder for future emails to reach the inbox. That is why removing unengaged subscribers raises deliverability rather than lowering reach.

Two changes worth making this week

Fix the sender name so it is your business name, spelled consistently, with a monitored reply address. Then pull the segment that has not opened anything in six months, send it one plain re-engagement email, and remove whoever ignores it.

Neither is a writing exercise, and both will move your open rate more than a month of subject-line experiments. Whether your platform makes the second one easy is a fair test of the platform.
