Your email subject line is the first part of your pitch that your prospects see. Itâs vital that you use it to catch their attention, give them an indication of why youâre reaching out, and frame the interaction moving forward.
In this guide, weâll show you tips on writing email subject lines for sales outreach, as well as actionable examples you can use in your own campaigns.
Letâs dive in.
The Importance of Your Email Subject Line for Sales
Your sales email subject line matters. Itâs the first thing your prospects see, and it frames the interaction theyâre expecting from you.
However, we always recommend that you avoid spending too much time on it.
Data from millions of emails sent with QuickMail found that the subject line doesnât make a big difference to the average email open rate or reply rate.
Why is that?
Well, most of your prospects will open every email they receive, as long as it lands in their primary inbox.
Once they open your email, theyâll forget about the subject line and will be focused on your email template and core value proposition being pitched to them.
As long as itâs authentic and doesnât come across as spammy, youâll be fine.
3 Tips for Writing Emails Subject Lines for Sales
1. Add Personalization Using Attributes to Boost Relevance
A simple but powerful way to make your emails stand out is to add personalization to your subject lines.
The most direct way to do this is by including your recipientâs first name or their company name.
Hereâs a good example in a sales email from Intercom:
By including both the recipientâs first name and the company name, itâs clear who itâs intended for and will stand out in the recipientâs inbox.
This wonât take the sender any extra time, either.
By using a cold email platform like QuickMail, you can do this in seconds.
When youâre writing your subject line, you can hit the âAttributesâ button. From there, you can choose which custom attribute you want to include.
When your email campaign sends, this will be personalized to every person on your email list.
2. Avoid Using Uppercase on Every Word to Look More Natural
If you were sending an email to a colleague, you wouldnât use upper caps. It comes across as inauthentic and would be more suited to a marketing email that needs to adhere to specific brand guidelines.
In your sales emails, use lowercase letters for your words.
Compare these two sales email subject line examples:
âHelp With {{company.name}}âs Email Marketing Strategyâ
âHelp with {{company.name}}âs email marketing strategyâ
Even though they say the exact same thing, one of them would feel instantly more personal in your inbox than the other.
3. Treat Your Subject Line as a Contract Between You and Your Prospect
This tip is a general approach to subject lines, rather than a direct and actionable tip.
When writing your subject lines for sales emails, treat every single one as a contract between you and your prospect.
As soon as they see your subject line, it should give them an idea of what youâre going to be talking about in the rest of your email.
If youâre reaching out to help them with lead generation, then there needs to be a reference to that in your subject line. If itâs about helping with their recruitment process, you need to mention it.
Having this mental model in mind ensures you donât end up writing vague or clickbait subject lines, and are instead focused on helping your prospect understand why youâre contacting them from the moment they see your email at the top of their inbox.
12 Example Email Subject Lines for Sales to Test in Your Campaign
1. The Simple Question Subject Line
One of the most popular frameworks for writing sales email subject lines is using a simple question.
By using a question, you incite curiosity into your recipient and at the same time, can frame what the rest of your sales email is about. Here are some examples:
âHelping {{company.name}} with Google ads?â
âHelp with landing page copy at {{company.name}}?â
â{{company.name}} sales goals for Q3?â
âIs lead generation a priority for {{company.name}}?â
2. Reference a Mutual Event or Acquaintance in Common
A shortcut to getting a response from any cold prospect is by referencing something you have in common.
The more tangible the mutual connection, the better this will work.
For example, if youâve attended the same conference for SaaS CEOs, thatâs a perfect icebreaker. If you both worked with a specific colleague at a previous company, or live in the same city, those are also good examples.
If you do this correctly, your prospect will immediately feel a level of goodwill towards you that wouldnât be there otherwise.
Here are some examples you can test:
âMorning coffee meeting in {{prospect.custom.City}}?â
âFollowing up after [conference] in {{prospect.custom.City}}â
âSaw that you also worked with [mutual connection]â
âCongrats on opening {{company.name}}âs new office in {{prospect.custom.City}}â
3. Skip Straight to Your Call-to-Action
One way to use your email subject line is to cut to the chase and use it as a call-to-action (CTA).
This is a higher-risk strategy because some prospects may think youâre being too forward. However, if you have an offer thatâs hard to refuse due to it being a perfect fit, you can test this type of subject line.
Here are some examples to consider:
15-mins to talk about lead generation on {{=day+2}}?
Collecting case studies from {{company.name}}âs best clients
Working together to boost {[company.name}}âs landing page conversion rate

How to Approach Your Follow-Up Sales Email Subject Lines
In most sales email campaigns, using the same subject line in your follow-ups is a best practice. Your prospects will appreciate that youâre not changing your message every few days in order to catch their attention.
However, if you do want to test a new subject line, you can easily do this in QuickMail.
When you add your follow-up email step, the default option is leave the subject line blank. This will use the same subject line as your previous email.
However, if you add a new subject line, it will send the email with a new subject line variation.
You can also choose whether to send the follow-up in the same email thread, or in a separate one.
This is an excellent way to boost your response rates if your emails are being ignored and you suspect itâs due to an underperforming subject line.
A/B Testing Your Sales Email Subject Lines
If you think your subject lines arenât effective enough, you can use QuickMail to run A/B tests.
First, add a new email variation to your campaign.
Then, write your new email subject line variation and save it. Itâs best to only test one variable at a time, so when you change your subject line, donât change anything else in the campaign.
When your email campaign sends, youâll see which one is generating the best results. When you have significant data, you can pause the underperforming variation and send the top performer to all remaining prospects.
Itâs a powerful way to test your hypotheses and ensure the subject lines youâre using are as effective as they can be.
