Caleb Ulku explains how the first 240 characters of an Upwork proposal cover letter — the 'intro hook' — are the only text visible to clients before they decide whether to open a proposal. He shows the client-side view of Upwork proposals to demonstrate that most proposals are never opened, and breaks down why common openers like 'Dear Client,' generic copy-paste lines, or self-promotional text fail. He argues that the intro hook must focus entirely on the client's problem, reference their specific project, and end with a cliffhanger (e.g., 'The way we achieve excellent results for our clients is...') to compel the client to open the full proposal.

View concept page →The intro hook is the first 240 characters of your cover letter that clients see when browsing proposals on Upwork. It's critically important because most proposals are never even opened — if a client doesn't open your proposal, they'll never respond to it. The goal of the intro hook is to give the client something so compelling that they can't resist opening and reading the rest of your proposal.
Clients see only the first 240 characters of your cover letter before deciding whether to open a proposal. This is what is referred to as the 'intro hook.' Everything visible to the client on the proposals list includes the freelancer's name, title, location, bid amount, total earnings, job success score, photo, and those first 240 characters of the cover letter.
When a client reviews proposals on Upwork without opening them, they can see: the freelancer's name, their title, where they live, their bid amount, their total amount earned on Upwork, their job success score, their profile photo, and the first 240 characters of the cover letter. That's all the information available before a client decides whether to open a proposal.
Common mistakes freelancers make in their Upwork intro hook include: (1) Starting with 'Dear Client' instead of using the client's actual name, which makes it feel like a copy-paste template; (2) Asking the client to check their previous feedback rather than making a compelling case in the hook itself; (3) Wasting the 240 characters talking about themselves rather than focusing on the client's project and pain points; (4) Starting with a URL, which is not attention-grabbing; (5) Filling the space with generic filler phrases like 'hope you're doing well and safe during the pandemic' without addressing the job at all; (6) Making it obviously a copy-paste message with no personalization.
Yes, absolutely. Using the client's name in your intro hook is vastly more attention-grabbing than starting with 'Dear Client.' Starting with 'Dear Client' immediately signals that your message is a copy-paste template, which damages your credibility. If the client's name is available in the job posting, use it — it creates a more personal connection and shows you took the time to read their posting.
The first 240 characters should focus entirely on the client — their project, their pain points, and why they posted the job on Upwork. Your client doesn't care about you; they care about themselves and solving their problem. You should also include a specific offer of value, such as offering to record a video walkthrough, do the first step of the job for free, or provide some other tangible next step. The intro hook should NOT be used to ask a bunch of questions or talk about yourself.
A great technique for ending the intro hook is to use a cliffhanger-style statement such as 'The way we achieve excellent results for our clients is...' and then cut off at the 240-character mark. This creates curiosity and compels the client to open the full proposal to find out what comes next. The goal is to end at a point that makes the client feel they need to read more.
You should write your intro hook in a word processor like Google Docs or Microsoft Word that provides a character count. This allows you to monitor exactly when you reach the 240-character limit so you can ensure the text doesn't cut off in the middle of a word or at an awkward point. Instead, you want it to cut off at a strategic moment that creates curiosity and compels the client to open the full proposal.
Most Upwork proposals never get a response because they are never even opened by the client. Clients receive many proposals (sometimes 40+ for a single job) and make quick decisions about which ones to open based on the limited preview information available — including the first 240 characters of the cover letter. If the intro hook is not compelling enough, the client simply moves on without ever reading the full proposal, making a response impossible.
In your intro hook, you should include a specific offer of value to the client. Examples include offering to record a video related to their project, completing the first step of the job as a demonstration of your skills, or providing some other concrete deliverable or insight. This offer should be something that directly addresses the client's needs and gives them a tangible reason to want to open your proposal and engage with you.
No, asking questions in the first 240 characters of your Upwork cover letter is not an effective strategy. Those 240 characters should be used to talk about the client, their project, and their pain points — and to make a compelling offer. Asking questions wastes valuable space and doesn't give the client a strong reason to open your proposal. Save questions for the body of the proposal after you've hooked their attention.
The example job posting for a 'small site in Shopify' received 44 proposals. This illustrates how competitive Upwork can be — clients are often flooded with proposals and must quickly decide which ones to open. This is exactly why the intro hook is so critical: with dozens of proposals to review, clients spend very little time on each one, and only the most compelling 240-character previews will earn a click.
Proposals without a compelling intro hook are simply never opened by the client. As demonstrated in the video, many proposals — shown as unread (light green shading) — were never opened at all, even though the client received 44 proposals and hired someone. If a proposal isn't opened, it has zero chance of receiving a response or landing the job, regardless of how strong the rest of the proposal content might be.
Starting your Upwork cover letter by asking the client to check your previous feedback is a waste of the precious 240-character intro hook. The client doesn't want to be directed elsewhere — they want to know, within those 240 characters, why they should spend more than two seconds on your proposal. Using that space to redirect them to your profile doesn't give them a compelling reason to open your proposal, and it misses the opportunity to address their specific project and pain points.
Getting your proposal opened is the essential first step in the entire hiring process on Upwork. If a client never opens your proposal, they can never respond to it, and you can never get the job. Improving your intro hook to increase the number of proposals that get opened directly increases your response rate, which in turn increases your chances of getting hired. The intro hook is therefore one of the highest-leverage improvements a freelancer can make to their Upwork strategy.
