Sales EmailTemplate

Free AI tool

Subject line generator

Stop sending "Quick question." Get subject lines that name the deal, the stall, or the next step.

Draft

Your draft will land here. Edit it before you send. The model does not know your deal.

Subject lines are promises. "Quick question" promises nothing. "Invoice 1042 is past due" promises a fact. This tool gives you options — you pick the one that matches the body.

Length matters less than specificity. A 42-character line that names the company and the stall beats a 28-character joke. Clickbait trains people to ignore your name.

Pick three options, send the honest one, and remember what got a reply. Your notes beat a leaderboard of tricks.

How it works

  1. Step 1

    Define the situation

    Email type, industry, and role set the register. The angle field is where you name the actual stall or object.

  2. Step 2

    Review options

    You get several lines ranked for clarity, not hype. Discard anything that overpromises what the body delivers.

  3. Step 3

    Match body to subject

    The first sentence of the body should deliver on the subject. Mismatch is why people stop opening your mail.

When to use this tool

Good fit

  • You have the body but cannot land the open.
  • Your current subject is "Following up" or "Quick question."
  • You want options that name the deal object, not fake urgency.

Skip it when

  • You need a full email — use the generator.
  • You want emoji-heavy marketing subject lines.
  • The email is internal — subjects can be plain sentences.

Example output

• SSO + SCIM — the question from the demo
• 15 min with our engineer on your rollout?
• [Company] — decision timing on the pilot

Frequently asked questions

How long should a sales subject line be?
Often 35–50 characters on mobile, but specificity matters more. Name the company, invoice, meeting, or decision when you can.
Should I use the prospect's name in the subject?
Only if it sounds natural for your relationship. "Alex — SSO packet" works. "JOHN URGENT" does not.
Can I A/B test subject lines?
Yes, but test honest variants, not bait-and-switch. If the body does not match the subject, you train them to ignore you.
Do subject lines affect SEO?
No. This is outbound sales mail. Subject lines affect open rate and trust, not Google rankings.
