In short: More people now meet your email through an AI summary before they see your design. Those summaries are built from words. When your offer, date, or ask lives inside an image, it can drop out of the one line your reader actually reads. Live text keeps your message readable for people, for assistive technology, and for AI.
Open your email on your phone and look at what greets you before the message itself. In Apple Mail, the line under each unread email is often a summary written by AI. In the Gmail app, a summary card can sit at the top of a longer email before anyone scrolls. That small change asks a big question of every email you send: where does your most important information actually live?
That question used to be about accessibility and broken images. It still is. There's also a new reader in the inbox now, and it reads before your people do.
What live text means
Live text is typed text in the body of your email. You can highlight it, copy it, search it, and have it read aloud. An image of text is a picture with words in it. On a good day the two look identical. Designers (I'm one) love images of text because we control every pixel. That control costs more than it used to.
AI reads your email first
The Gmail app on Android and iOS shows Gemini summary cards automatically on longer emails (Google Workspace Updates). In Apple Mail with Apple Intelligence, "a short summary automatically appears under each unread email in your inbox" (Apple Mail User Guide).
Those summaries are built from your words. When the date, the offer, and the button live inside a picture, you're leaving the most important part of your message to chance. Picture a church member in the school pickup line. The summary says "A holiday message from your church." The service times were in a graphic, so they never made it into that line.
What a screen reader hears
Many people listen to their email. A screen reader, like VoiceOver on an iPhone or Mac, reads it aloud from top to bottom.
Good alt text is read as written: "Christmas Eve services at 4:00 and 7:00 PM."
Missing alt text may be read as the file name, like "holiday-banner-final-v3.png" (axe rule: image-alt).
Empty alt text (alt="") on decorative images tells the screen reader to skip them.
Layout tables can be read cell by cell unless they're marked role="presentation" (Bureau of Internet Accessibility).
Live text fixes most of this on its own. It's read in order, and real headings let a listener skip ahead.
The readers who were always there
Classic Outlook blocks automatic picture downloads by default (Microsoft Support), so many people see empty boxes until they click. People with low vision restyle text to read it, which is why accessibility guidelines ask for real text over images of text (W3C, WCAG 2.2). And when someone searches their inbox for "Christmas Eve" in December, live text is what shows up.
One myth to drop: image-heavy emails generally don't cause spam problems on their own (Spam Resource). The real cost is people missing your message.
My rule of thumb
Images carry the feeling. Text carries the facts. Use images for photos of your people and place, hand-drawn accents, icons, dividers, and your logo, and give decorative ones empty alt text. Use live text for headlines, dates, times, locations, offers, prices, and buttons, styled in your brand fonts.
Built this way, your email keeps its personality and its meaning for every reader.
Try this this week
Do the highlight test. Try to select every word in your last email. Anything you can't select is an image.
Move the facts into live text. The offer, date, time, location, and button text.
Write alt text that says what the image says. Leave it empty on purely decorative images.
Listen to it. Turn on VoiceOver (iPhone: Settings, then Accessibility) and let your phone read the email aloud.
Turn images off and read it. If it still makes sense, you're in good shape.
Read your own summary. Send yourself a test in the Gmail app or Apple Mail. If the AI misses the point, rewrite the top of the email.
The heart of it
Every email is a small act of hospitality. Live text makes sure everyone hears the invitation: the guest with images blocked, the volunteer listening through a screen reader, the parent skimming a summary between errands.
