25 Email Preview Text Examples That Boost Opens
Email preview text is the short snippet of copy that appears next to or beneath your subject line in the inbox, pulled from the first readable text in your email or from a hidden preheader you set deliberately. Good preview text does not repeat the subject line — it extends it, adding the specific detail, number, or curiosity gap that turns a glance into an open.
Why preview text is the most wasted real estate in email
Most senders spend an hour on the subject line and zero seconds on the preview. The result is an inbox full of emails whose preview reads View this email in your browser or Having trouble seeing this message? That is roughly 35–90 characters of prime persuasion space handed over to boilerplate.
Think of the subject line and preview text as one two-part sentence. The subject makes a claim or opens a loop; the preview delivers the proof or widens the loop. When you write them together, open rates move — in our experience the lift is usually modest but consistent, on the order of a few percentage points, which compounds across every send you make for the rest of the year.
How long should preview text be?
Length depends entirely on the client and device. There is no single correct number, but these approximate display windows are a safe planning guide:
| Client / context | Approx. characters shown | Practical implication |
|---|---|---|
| iOS Mail (iPhone, 2-line preview) | ~70–90 | Front-load the hook in the first 40 |
| Gmail app (mobile) | ~40–55 | Shortest window — assume truncation |
| Gmail web (desktop) | ~90–110 | Room for a full second sentence |
| Outlook desktop | ~55–70 | Avoid burying the verb |
| Apple Mail (Mac, 3-line) | ~140+ | Extra text is bonus, never load-bearing |
The working rule: write the essential message in the first 40 characters, then keep going to about 90. The tail gets read on desktop and quietly truncated on mobile, which costs you nothing.
25 preview text examples you can adapt

The five patterns behind every good preview
- The specific detail. The subject makes a general claim; the preview names a number, a size, a date. Four in stock. Nine days. 12 seats.
- The objection killer. The subject asks for something; the preview removes the friction. Nothing to copy. No action needed. Your data stays put.
- The widened loop. The subject opens curiosity; the preview raises the stakes rather than resolving them.
- The navigation hint. Tell people where to go inside the email. Skip to 14:20. This works unreasonably well for long emails.
- The honest aside. A human parenthetical — it took us four months, sorry — reads like a person, not a campaign.
Preview text mistakes that quietly cost you opens
- Leaving it blank. The client then scrapes your first line of body copy, which is usually an image alt tag or a view-in-browser link.
- Repeating the subject verbatim. You just spent your second impression saying the same thing twice.
- Starting with the recipient's name. Personalization tokens burn your first eight characters on something the reader already knows.
- Emoji pile-ups. One is fine. Three renders as boxes in some clients and reads as spam in others.
- All-caps urgency. Filters notice, and readers stop believing the deadline after the third one.
- Forgetting the padding trick. If your preview is short, some clients keep scraping body copy to fill the gap. Add non-breaking space entities after your preheader div so the client has nothing else to grab.
How to write and test them in practice
Write the subject and preview in the same sitting, in the same field of view, then read them aloud as one sentence. If the sentence is redundant or the second half does not earn its place, rewrite the preview, not the subject.
Then test. Preview text is one of the cheapest A/B variables you have — the creative stays fixed and only the inbox impression changes, so the result is clean. Hold the subject constant and run two previews against a slice of your list before rolling out. If you want a fast starting point, run your candidate subject through our free subject line tester and write the preview to fill whatever gap it flags.
One structural note: your preheader must be hidden text at the very top of the HTML body, not visible copy in your header. Every layout in our library of 100+ email templates ships with the hidden preheader block already in place, so you fill one field and the rest is handled.
A quick pre-send checklist
- Preview text is filled in and does not repeat the subject
- The hook lands inside the first 40 characters
- Total length is roughly 60–100 characters
- Padding entities follow the preheader so nothing else gets scraped
- You have sent yourself a test and looked at it on a phone, not just a laptop
- At most one emoji, and it renders
Frequently asked questions
What is email preview text?
Preview text, sometimes called preheader text, is the snippet of copy an inbox displays alongside the subject line before the email is opened. It is pulled from a hidden line at the top of your HTML or, if you do not set one, from the first readable text in the email body.
How long should email preview text be?
Aim for roughly 60 to 100 characters, with the most important words in the first 40. Mobile Gmail can cut off around 40–55 characters while desktop clients often show 90 or more, so the tail should be a bonus rather than essential information.
Does preview text actually increase open rates?
Yes, though usually by a few percentage points rather than a dramatic jump. The gain is reliable because preview text is a second persuasive impression at no extra cost, and it compounds across every campaign you send.
Should preview text repeat the subject line?
No. Repetition wastes your second impression. Treat the subject and preview as two halves of one sentence, where the preview adds a specific detail, removes an objection, or deepens the curiosity the subject created.
Why does my email show “View this email in your browser” in the inbox?
That happens when no preheader is set, so the client scrapes the first text it finds in your HTML. Add a hidden preheader div as the first element inside the body, followed by padding characters, and the placeholder disappears.
