Learn the best email subject lines for sales and follow-ups in 2025. Get proven templates, follow-up examples, and expert tips to boost your open rates and book more meetings.

Gary Chan

Founder; 3x Head of Growth

What makes the best email subject lines for sales?

The subject line is the first (and sometimes only) impression your email makes. A great sales subject line is the difference between being opened or ignored. In 2025, as inboxes overflow and attention spans shrink, crafting the right subject line matters more than ever.

Keep it short and sweet

  • Subject lines under 45 characters perform best.

  • Aim for 5-7 words max.

  • People scan, they don’t read — your subject should hook attention immediately.

Tailor to your audience

  • B2B tech founders? Use metrics and outcomes.

  • Ecommerce brands? Use seasonal hooks or customer-first offers.

  • Personalize with name, company, industry, or recent trigger events.

Offer Clear Value

  • Don’t make them guess.

  • Highlight your offer, outcome, or benefit directly in the subject.

Why is a Sales Email Subject Important?

The subject line drives your open rate, which impacts every downstream metric: replies, meetings booked, and sales closed.

  • 47% of recipients open based on subject line alone.

  • 69% report emails as spam purely from the subject line.

A strong subject signals relevance, clarity, and value—critical for cutting through the noise in 2025.

Cold Email Sales Subject Lines

Subject 1: "Quick question for [Job Title] at [Company]"

  • Follow-up: "Following up on my quick question, [Name]"

  • Best Timing: Mid-week, early morning (8:00-9:00 AM).

  • Best Industries: SaaS, professional services, agencies, and B2B tech.

  • Localization: Works globally with minor tweaks (e.g., “small ask for [Job Title]” for UK).

  • Similar Examples:

    • “Is this your top priority right now?”

    • “Quick ask about [pain point] at [Company]”

Subject 2: "[First Name], worth a quick chat?"

  • Follow-up: "Circling back – still worth connecting?"

  • Context: Personal, casual, and polite. This feels low-pressure but personal.

  • Best Timing: Tuesday-Thursday, lunchtime.

  • Best Industries: Consulting, software, professional services.
