How Long Does the Average Person Read a Sales Email? (2026 Attention Data)

How long does the average person look at a sales email? Most reps write for a reader who doesn't exist — someone who has time to absorb three paragraphs of context and a detailed pitch. The actual reader gives you 9–11 seconds.

This post covers what the eye-tracking and engagement data says about sales email attention, and what it means for every decision you make about copy length, subject lines, and formatting.

The Attention Data

The average person spends 9 to 11 seconds looking at a sales email before deciding to read, skim, or delete it. That number comes from Litmus's 2025 State of Email report, based on over 3.5 billion email open events. Here is the full breakdown:

Average across all reads: 9.2 seconds. For B2B cold emails (no prior relationship), the average drops closer to 7.3 seconds — cold recipients engage less deeply than subscribers or warm prospects.

Open vs Read vs Skim: The Difference

Not every email open is a read. There are three distinct levels of engagement — open, skim, and read — and most cold emails lose recipients at the skim stage, not the open stage.

Open: The email was loaded. The subject line and first line were scanned in the inbox. The reader decided it was worth clicking.

Skim: The reader spent 2–8 seconds scanning for relevance cues — bolded text, short paragraphs, a CTA. If the email is too dense or too long, skimmers close without reading.

Read: 8+ seconds of active reading. The reader is genuinely evaluating the content. This is when the reply decision happens.

The conversion funnel for a cold email: open (subject) → skim (structure) → read (content) → reply (value + ask). Most cold emails lose recipients at the skim stage — not the open stage.

What Gets Read in 11 Seconds

Nielsen Norman Group's eye-tracking research on email shows that in the first 11 seconds, readers fixate on:

1. The first 2 sentences — the highest fixation time of any part of the email
2. The last sentence or CTA — readers scroll to the end to see what's being asked
3. Any bolded or formatted text — the eye is drawn to visual anchors
4. The sender name — especially on mobile, where the from-name is prominent

Everything between the second sentence and the last sentence is largely skipped unless the first 2 sentences earn the read. This is why long emails with good opening sentences perform better than long emails with weak opening sentences — but neither performs as well as a short email with a strong opener.

Implications for Subject Lines

Keep subject lines under 40 characters and make the first sentence continue the promise of the subject line. The subject line determines the open — but the pre-header and first sentence determine whether the open converts to a read. Most email clients show 40–80 characters of the first line as the pre-header preview.

• Keep subject lines under 40 characters for full mobile display.
• Make the first sentence the continuation of the subject line. The subject says the topic; the first sentence says why it matters to this person.
• Avoid clickbait subject lines. When the body doesn't deliver on the subject, readers close within 2 seconds — the worst outcome for sender reputation.

Implications for Copy Length

The ideal cold sales email is 50 to 125 words. Boomerang's analysis of 40 million emails found the highest reply rate in that range. The 11-second attention budget maps directly to this: at average reading speed (250 words per minute), 11 seconds covers about 46 words. A 75-word email can be read completely in 18 seconds — within the range of an engaged reader.

Cut everything that doesn't do one of three jobs: (1) hook the reader in the first 2 sentences, (2) establish relevance in the middle, (3) present the CTA in the last sentence.

Implications for Formatting

Plain text emails outperform HTML for cold sales outreach. Plain text reads as personal. HTML reads as marketing. An email that reads as marketing gets skimmed with the "delete this promo" reflex.

Short paragraphs (1–2 sentences) reduce visual density. Bullets signal a template — avoid them in the first cold email. White space between sentences invites the eye to rest and continue. One link maximum in a cold email — more than one signals a bulk send. For sample templates that follow these rules, see B2B sales email templates.

Writing for 11 Seconds: A Framework

Write every cold email with the assumption that you have 11 seconds of active reading. That 11 seconds must accomplish four things:

1. Seconds 1–3: The first sentence convinces the reader this was written for them specifically
2. Seconds 4–6: The second sentence connects their situation to a specific outcome you can deliver
3. Seconds 7–9: The credibility anchor — one specific result for a comparable company
4. Seconds 10–11: The ask — one question or one action

A cold email that does all four in under 80 words is ready to send. One that requires 200 words to say the same things will not get read. Cut until it fits in 11 seconds.
