Proposal inside, decision by [date]?
This one goes on proposal email subject line use cases. It combines content and timeline information, so the reader knows what the email contains and the timeframe for action.
The bracketed date creates a sense of urgency without pressuring the reader, who can adjust as needed.
Tips: Match body copy to the deadline, and include a clear summary of value, pricing, and next step.
Example Email:
Subject: Proposal inside, decision by June 12?
Hi [Name],
Attached is the proposal we discussed, showing the phased rollout, costs, and projected metrics.
Review before June 12 if possible, so the team can lock in the current rate.
If that date is too soon, let me know and I’ll adjust accordingly.
Best,
[Your Name]
Proposal inside, a quick win for your team
Tone
Clear, Upbeat
Why It Works
The phrase “quick win” hints at fast value. Adding a tangible benefit can increase open rates by 15% (Litmus study).
When to Use
Use this kind of subject line right after you finish tailoring the proposal. The promise of speed fits early-stage discussions where decision makers want rapid impact.
Example Email
Hi Sam,
I attached a one-page proposal that trims onboarding time by 25%.
Take a peek when you have five minutes. If you like it, we can lock in next steps by Friday.
Best,
Aisha
Thoughts on our [Project Name] proposal?
A question in subject lines invites reply. Slot the project name in brackets to ground the ask.
It’s a perfect for after an initial deck share. You gently nudge for input without sounding pushy.
Tips
- Keep the question direct. Scattershot wording bumps the email into spam filters.
- Set a follow-up reminder in two days. See our follow-up subject line guide for wording.
Type
Professional, Collaborative, Feedback-oriented
Tone
Conversational, Curious
Next steps for our partnership proposal
People skim inboxes for clear actions and “Next steps” signals momentum.
Drop this line after the prospect confirms interest. You steer the conversation toward closing without hard sell language.
Type: Business, Sales Enablement
Tone: Action-oriented, Confident
This Subject Line Can Also Be:
- Ready to move on our proposal?
- Let’s finalize the proposal this week
Draft proposal ready, eager for your feedback

Use this kind of subject line after you create a first draft but before polishing. You collect early feedback and spot blockers early.
Type: Collaborative, Service-oriented
Tone: Friendly, Respectful
Example Email
Hey Jordan,
I just wrapped a draft proposal covering timeline, scope, and cost breakdown.
I’m eager to hear what resonates and what feels off.
Could we hop on a 15-minute call Wednesday?
Thanks,
Drew
Brief proposal summary, see if it fits your goals
“Brief” respects time. “Fits your goals” speaks to relevance.
It’s an Ideal proposal line for C-suite contacts who scan quickly. You front-load clarity so they click.
Tips
- Attach a one-pager PDF, not a 30-slide deck.
- Close with a light CTA: “Worth a chat?” feels low-pressure.
Type: Consultative, Client-focused
Tone: Helpful, Neutral
Proposal for [project or initiative name]
Type:
Formal, Professional, Client-facing
Tone:
Clear, Straightforward, Respectful
Content:
Sometimes, plain works best. This proposal email subject line is especially useful in formal settings, like submitting a proposal to a procurement officer, RFP manager, or enterprise client.
Include the name of the project or initiative here, so it’s immediately recognizable. If it’s part of a competitive bid, this helps your email stand out and stay organized in their inbox.
There’s no fluff, just clear intent. I wouldn’t recommend this for casual proposals or early-stage leads, but for big deals or contract submissions—It nails it.
And for follow-ups later, you can refer back to it easily: “Following up on Proposal for [Project Name].”
Here’s what I propose for your [goal or challenge]
Type:
Sales, Pitch, Personalized
Tone:
Helpful, Friendly, Consultative
Content:
This subject line is like a problem-solver. Instead of sending “just a proposal,” you’re offering a solution to something they care about.
Use this kind of lines after you’ve identified a clear pain point, like slow onboarding or poor churn rates.
Mentioning the goal or challenge directly helps the reader feel seen. You’re not just guessing—you’re addressing something specific. Plus, the phrasing “here’s what I propose” feels collaborative, not forceful.
This Subject Line Can Also Be:
- Here’s an idea to boost [KPI or result]
- My proposed plan to tackle [problem]
- Thinking through your [goal]? I put together something
