iMessage Open Rates vs Email: What the Numbers Really Say

Industry reports have cited open rates of 95–98% for text messages for years, while email benchmarks land between roughly 20% and 36% depending on the year and how opens are counted. Both numbers get repeated constantly, and both deserve a closer look before you build your customer communication around them. This post walks through where the figures come from, what they actually measure, why blue-bubble messages get read, and what the gap means for a small business deciding where to spend its attention.

What an Open Rate Actually Measures — Email vs Text vs iMessage

Before comparing numbers, it helps to understand that "open rate" means something different on every channel. The definitions differ enough that comparing raw percentages without context is misleading.

How email opens are counted

When you send a marketing email, the software hides a tiny invisible image inside it. When someone's email app loads that image, the send counts as "opened."

That method was always imperfect. Some email apps block images, so real reads go uncounted. Some people read in preview panes that never load the image at all.

Then in 2021, Apple released Mail Privacy Protection, which loads those tracking images automatically — whether or not a human ever looks at the email. Since then, a meaningful share of recorded email "opens" are machines, not people.

So an email open rate is a tracked number, but the tracking now overcounts in one direction and undercounts in another. Nobody can say exactly how far it sits from real human attention.

How text message opens are counted

Text message opens are not tracked at all. There is no hidden image inside a text, and no reporting system that records the moment a person reads one.

The 95–98% figure you see everywhere is an estimate built from delivery confirmations and observed reading behavior, not a direct measurement.

What the number really describes is visibility. A delivered text lands on the lock screen of a device the recipient checks throughout the day. Nearly everyone sees nearly every text they receive.

How iMessage is different

iMessage adds something neither of the others has: real read receipts. According to Apple's own explanation of how iMessage works, iMessage supports delivery receipts, read receipts, and typing indicators, and conversations are encrypted end to end.

When a recipient has read receipts turned on, "Read" means a person actually opened the conversation — not that software loaded an image somewhere.

Read receipts are controlled by the recipient, so you will not see them for everyone. But they are the only honest "open" signal in this entire comparison.

Here is the same idea in table form:

| Channel | How an "open" is counted | What distorts the number | |---------|--------------------------|--------------------------| | Email | Hidden tracking image loads | Auto-loading since 2021 inflates it; image blocking deflates it | | Text message (SMS) | Estimated from delivery + behavior | No direct measurement exists; it describes visibility, not engagement | | iMessage | Delivery receipts, plus read receipts when enabled | Read receipts are recipient-controlled, so reported reads undercount |

The takeaway: email open rates are a soft number that has drifted further from reality since 2021. Text open rates are an estimate of visibility that has held steady across years of industry reporting. iMessage is the only channel where a "read" can be a literal fact.

iMessage Open Rates vs Email: The Honest Numbers

Now the figures, with sources and years attached — and honest caveats where the sourcing is thin.

Email: roughly 20–36%, depending on when and how you measure

Mailchimp's email marketing benchmarks report puts the average email open rate across all industries at 35.63%, with the underlying data last updated in December 2023.

That figure sits well above the roughly 20% averages that were widely reported before 2021. The difference is largely Apple's Mail Privacy Protection inflating the count — not a sudden surge in human attention.

Real human open rates sit somewhere below the tracked number. How far below depends on how much of your audience reads email on Apple devices, which you cannot see from the outside.

Text messages: 95–98%, an industry estimate that has stayed stable

This range has been repeated in industry reports for over a decade, and it still appears in benchmark roundups published in 2026.

No single study directly measured it, because texts cannot be directly measured. The figure is an inference: deliveries are confirmed, phones are checked constantly, and texts have no spam folder to disappear into.

Treat it as a claim about near-universal visibility — the message reached a screen the person looks at — rather than a precise engagement metric.

iMessage specifically: no separate published number

We could not find a separately published, verifiable iMessage-only open-rate study, and we are not going to invent one here.

What can be said with confidence: iMessage rides the same lock-screen visibility as any text message, and it adds confirmed delivery and recipient-controlled read receipts to that baseline. It cannot land in a spam folder, and delivery is confirmed rather than assumed.

If texting as a category sits at 95–98% visibility, iMessage sits at the high end of that category.

What the gap means once you discount both sides

Suppose you are skeptical of every number above — reasonable, given how they are produced. Run the comparison with the skepticism dialed all the way up:

• Discount the texting figure aggressively, down to 80%.
• Give email full credit for its tracked 35.63%, even though some of those opens are machines.
• The gap is still better than two to one, in texting's favor.

Under any honest reading of the data, a text is dramatically more likely to be seen than an email. The exact percentages are debatable. The size and direction of the gap are not.

The numbers worth watching instead

Because "opens" are murky on every channel, the healthier habit is watching signals that are actually measured:

| Signal | What it tells you | Where you see it | |--------|-------------------|------------------| | Delivery confirmations | The message reached the device | Reported on every senderZ message | | Replies | A human read it and cared | Your message threads | | Opt-outs (STOP replies) | You are messaging too often, or the wrong people | Your opt-out list | | Bookings, visits, purchases | The message did its job | Your calendar and register |

If deliveries are confirmed and opt-outs stay low, your visibility is close to the ceiling — regardless of what any dashboard claims about opens.

Why iMessage Gets Opened and Email Gets Skimmed

The visibility gap is not a marketing trick, and it is not about writing better subject lines. It is structural — built into how each channel reaches a person.

Texts land on the lock screen; emails wait in a queue

A text produces a notification on a device the average person checks dozens of times a day. It interrupts, politely, at the moment it arrives.

An email joins a pile that gets processed in batches, whenever the recipient next sits down to deal with the inbox. Industry reporting has long observed that the large majority of texts are read within minutes of arriving, while emails routinely wait hours or days.

For anything time-sensitive — a reminder about tomorrow's appointment, a table that is ready now — that speed difference matters as much as the open rate itself.

There is no spam folder for texts

Before a human ever sees your email subject line, the message has to survive spam filtering, a promotions tab, and bulk-mail sorting. Plenty of legitimate business email dies in that gauntlet without the sender ever knowing.

A delivered text has no equivalent obstacle course. Delivery is the only gate, and once through it, the message is on the screen.

People get far more emails than texts

An inbox holding dozens of unread messages trains its owner to skim and delete. A text thread is scarce space, occupied mainly by family, friends, and coworkers.

Each individual text carries more attention because there are fewer of them competing for it. This is also the channel's built-in warning: the moment businesses overuse it, the scarcity — and the attention — erodes.

The blue bubble carries social context

An iMessage arrives in the same app, with the same appearance, as messages from people the recipient knows. Typing indicators, read receipts, full-quality photos, and end-to-end encryption make the thread feel like a conversation rather than a broadcast.

A business that shows up there inherits that context — and it cuts both ways. You get the attention of a personal channel, and you are held to the standards of one. A pushy or irrelevant message inside someone's personal message threads does more damage than the same message would do in an inbox.

Green bubbles get seen too

Not every customer has an iPhone, and a message that falls back to standard SMS shows up as a green bubble instead of a blue one. The good news: the visibility argument holds either way.

Green-bubble texts land on the same lock screen, skip the same spam folder, and get read on the same schedule. What changes is the extras — read receipts, typing indicators, and full-quality photos are iMessage features, not SMS features. Your Android customers still see the message; you get less feedback about it.

A real number invites replies

Business texts come from a phone number that can receive answers. A customer who wants to reschedule, ask a question, or say thanks can do it in the same thread, in seconds.

Compare that with a no-reply email address, which announces that the sender does not want to hear back. Two-way channels earn more trust, and trust is what keeps open rates high over time.

What iMessage Open Rates Mean for a Small Business

High visibility is only worth something if you use it for messages that deserve it. Here is how the math plays out, and where each channel belongs.

An illustration (not a statistic)

Say you run a salon and need to remind 200 clients about appointments this month. These numbers illustrate the gap; they are not a benchmark:

• Sent by email at a 30% real open rate, roughly 60 clients see the reminder. The other 140 may or may not remember on their own.
• Sent by text at 95% visibility, roughly 190 clients see it — and the ones who need to reschedule can reply in the same thread instead of no-showing.

Fewer empty chairs, fewer awkward phone calls. The difference came entirely from the channel, not the wording.

Where texting earns its open rate

• Appointment reminders and confirmations — time-sensitive, expected, and useful. The single clearest use case for any service business.
• Order and service updates — "your table is ready," "your car is done," "your order shipped."
• Replies to inquiries — someone who texted you first is waiting for the answer where they asked.
• Review requests right after a good visit — one short message while the experience is fresh.
• Short, occasional offers to people who opted in — scarcity is the whole reason texts get read, so treat the channel as a limited budget.

What this looks like across local businesses

The same visibility advantage shows up in different shapes depending on what you do:

• Salons and barbershops — reminders the day before, a rebooking nudge a few weeks after a visit.
• Dental and medical offices — confirmations that actually get confirmed, recall reminders that actually get seen.
• Auto shops — "your car is ready" the moment it is, plus estimates the customer can approve by reply.
• Restaurants — waitlist and reservation updates while the guest is standing outside.
• Real estate agents — new-listing alerts and showing confirmations that beat the competing agent's email to the phone.

In every case, the message is expected, useful, and short — which is exactly the kind of message that keeps a texting list healthy.

Where email still wins

Email is not obsolete, and an honest comparison includes the cases it wins:

• Long-form content — newsletters, detailed announcements, anything a customer might scroll through.
• Documents and receipts — things people file away and search for later.
• Low-urgency updates — monthly summaries and content that can wait for inbox time.
• Rich formatting — layouts, product grids, and images that need a bigger canvas than a message bubble.

Use both, on purpose

The pattern that works for small businesses is pairing: urgent and personal goes to the message thread, long and referenceable goes to the inbox. Neither channel replaces the other; they cover each other's blind spots.

How to Keep Open Rates High Without Burning Your List

Texting's open rates are a shared resource. Every business that abuses the channel trains customers to ignore it — and gets its own number flagged. Keeping the visibility advantage means treating the channel with restraint.

Get permission first

Only text people who agreed to hear from you, and keep a record of when and how they agreed. Under U.S. law (the Telephone Consumer Protection Act), consent is not optional, and the penalties for ignoring it are real.

Permission is also what protects your open rates. A list of people who asked to hear from you reads its messages; a list of people who did not, reports them.

Honor STOP immediately

When someone replies STOP, every future message to them must halt — no final "sorry to see you go" note.

senderZ processes STOP replies automatically and blocks future sends to that person without any action on your part. Our opt-out handling guide explains exactly how that works.

Respect quiet hours

Nobody wants a promotion at 11 p.m. senderZ holds marketing messages during evening and overnight hours — 8 p.m. to 8 a.m. in the recipient's local time — without you having to think about it.

Ramp up gradually

Blasting hundreds of strangers from a brand-new number is the fastest way to get flagged as spam, on any texting service.

senderZ builds pacing into every plan: each plan allows a set number of first-contacts per day, while messaging people who have texted you is unlimited. The daily limit is not a restriction on your business — it is the discipline that keeps your number trusted and your messages arriving.

Watch your delivery confirmations

Every message you send through senderZ comes back with a confirmation of whether it was delivered. If deliveries dip, something is wrong — a stale contact list, or too aggressive a pace — and catching it early protects the whole list.

Keep each message worth opening

Compliance keeps you out of trouble; message quality keeps you out of the mental spam folder. Three habits cover it:

• Identify yourself in the first line. "Hi, it's Maria from Bloom Salon" beats a mystery number every time.
• Make one point per message. A reminder is a reminder. Save the promotion for its own, occasional send.
• Send less often than you think you can. The open-rate advantage exists because texts are scarce. Every unnecessary send spends down that scarcity.

Customers rarely complain about a useful text. They opt out over frequency and irrelevance — the two things entirely within your control.

Let the routing work for you

senderZ checks whether each recipient can receive iMessage before sending, delivers the blue-bubble version when they can, and falls back to a standard text when they cannot. You send one message; the routing happens on its own.

The senderZ setup guide shows the whole flow, from signing up to sending your first message.
