How to Write a Business Proposal Email

Sending out a proposal over email is tricky business – whether you’re reaching out cold or following up on a recent meeting. Chances are, the person you’re trying to reach will have a busy inbox, so it’s up to you to make your message stand out.

It’s important to follow the correct email format when writing a business proposal email. The templates below should give you a rough idea on how to format it correctly.

Business Proposal Email Format

You can start creating business proposal emails quickly and easily if you follow a simple 5-step format:

1. Subject Line

Your business proposal email subject line needs to accomplish a few different things. First of all, it should be attention-grabbing. You’ve only got a few seconds so every word you use here matters.

Secondly, you need to make your subject line relevant and get right to the point. This shows professionalism and a respect for your recipient’s time.

Lastly, use the recipient’s name whenever possible. This makes your email have a more personalized feel.

Some example subject lines to use are:

  • “[Name] – My proposal regarding the new launch”
  • “Hey [Name] – Please look this over”
  • “[Company Name] Proposal”

2. Greeting

Once you have gotten your recipient to open your email by making it catchy, personal, and relevant, you need to work out the greeting you’re going to write.

There are several schools of thought regarding what a greeting should look like. Some feel that you should go with a personal and informal greeting. Others would claim that you should keep it ultra formal.

The reality is that a great greeting depends on the market or person you are addressing, and your relationship to them. Obviously saying “Hey Buddy” wouldn’t be very appropriate if you’re cold emailing a C-level executive that you’ve never met.

That being said, here are a few greetings ranging from least formal to most formal that you can use to start off your email:

  • “Hey [first name]!”
  • “Good afternoon [first name]”
  • “Dear [Mr. / Mrs. Last Name]

3. Opening Line and Body

Think of the opening line as an extension of your subject line. Go into more depth about the purpose of this email. In other words, tell your recipient what to expect in the words to follow.

For the purposes of a proposal, you also want to include some kind of “hook” — this is some kind of useful information or promise of value within your proposal.

As an example, you might have a very dense body paragraph with the information outlining your proposal. However, this might look intimidating to read at first glance.

So you can give them a brief overview first, like “We’ve found a way to save your company 30% on your office supplies over the next year.”

Then, you can simply fill them in on the details of the proposal throughout the body as you normally would.

4. Ending

You can think of the business proposal email ending as the inverse of the opening and greeting. It will be a lot less detailed and a lot more general than the body.

Use the ending as a chance to wrap up the email by providing a brief summary of what your proposal is. In addition, you’ll want to end with a call-to-action. This way, you tell your recipient what the next step is in the process and take leadership.

Here’s an example ending utilizing the concepts above:

“In summary John, by working with ABC Office Supplies, we can save your law firm 30% on your office expenses annually. Please let me know if you’d like to move forward on this agreement or if you have any other questions. Talk soon.”

5. Signature

The final part of your proposal is your signature. This may sound like simply signing off with your name, but it’s a little more involved than that depending on your goals.

Sure, you can simply sign off with a “Regards, [Your Name]” type of signature. This is short and sweet.

However, consider adding some more pizzazz to your signature with potential social media links, product or sales page links, and additional contact information. These can be helpful if you are trying to expand your footprint and the ways in which your recipient can reach back out.

Proposal Email Top Tips to Follow

There are a few tips and tricks that will help you get your proposal in front of the right person and convince your target that you have what they’re looking for.

1.   Research and Target Your Recipient

Before you even begin to write – let alone send – your proposal email, it’s important to know who you’re addressing it to. This will ensure you nail the style and tone of the proposal, but it will also allow you to personalize your email and reach the most appropriate person.

If you’re sending your proposal email out cold, then locating your target’s email address might be tricky, if not impossible. If you cannot find the exact address, then at least know the name of the recipient so that you can refer to them in the subject line and email body.

2.   Nail Your Subject Line

The value of your subject line cannot be underestimated when sending out an email proposal. It’s the first thing your recipient will see in their inbox and is your first (and sometimes only) chance at a good impression. According to Optimonster, 47% of email recipients will open an email entirely on the basis of the contents of the subject line.

The key to the subject line is to be clear about what’s in the email. This may seem like an obvious point, but people often make the mistake of disguising the real purpose of their email with an ambiguous subject line as if to “trick” the recipient into opening it.

Another top tip: if you can, personalize your subject line. If you do, you might expect a 26% better chance of your email being opened.

3.   To Attach or Not to Attach

When you’re sending your proposal via email, you have the choice to include the proposal as an attached document or to include it in the body of the email.

While adding as an attachment could affect its deliverability, it’s also important not to send out lengthy email messages to unsuspecting recipients. In fact, HubSpot argues that emails should be no longer than 200 words.

The main thing to ask yourself is whether your proposal is a quick 2-3 sentence affair (and can therefore fit into your email body), or whether it requires a lengthy in-depth document (to be sent as an attachment). The key is to be clear – in the subject line if possible – that your proposal is included as an attachment to your email.

4.   Stick to the Point

It’s important that both the proposal itself, as well as the email copy, remain relevant and helpful and not ramble on for paragraphs on end.

Make sure to provide all the information your recipient may need, whether that be all ways of contacting you, costs, timelines, and summary of your proposal. Your email proposal needs to do all the hard work so that your recipient can see exactly what they should expect from you if they were to go ahead and hire you.

5.   Sell Your Offering

Your proposal email really is your chance to showcase why you are the right person to hire, so seize the opportunity! Whether you’re a freelancer looking for work, or a company reaching out for a new contract, it’s down to your proposal to explain exactly what you’re offering and what makes you better than anyone else to deliver it.

If you’re sending out your proposal to more than one recipient, make sure you tailor this part so that your skills, expertise, and experience are relevant to each company’s specific needs.

6.  Get the Timing Right

There’s no doubt that moving quickly is the key to clinching a new gig. But exactly how quickly is up to some interpretation.

It’s generally held as best practice to send your proposal email within 24 hours of being in touch with your target recipient. It demonstrates that you are keen and organized, but you’re also fresh in their minds.

If you want your email to get opened right away, then try and hold off from sending it at 2am. Likewise, avoid the 9am-11am rush hour. Ideally, you want to be sending your email in the middle of the day, when your recipient is most likely to be sitting at their computer.

Right Inbox’s send Later feature can help you to set your own time delay so that, if you’re eager to compose your message and get it out the door, you can rest easy knowing that it’s been scheduled to arrive when it’s most likely to get it seen.

7.   Follow Up

One of the worst mistakes you can make once you’ve sent your super-charged proposal email is to neglect to follow up. You don’t need to harass your recipient, but a courtesy message a few days after your initial email will demonstrate that you are serious about your proposal and, hopefully, worth a punt.

In Summary

Emailing a proposal to a new client, boss, or partner doesn’t need to be as difficult as it seems. If you’ve done some sound target research then your knowledge of their working challenges will shine through.

Keeping your proposal and email succinct, sending it at the right time, and following up are all things that will give your proposal an extra chance of getting in front of the right eyes, and getting you hired for the job.
