Chilly outreach emails suck. There, I mentioned it.
Sadly, chilly emails are additionally ubiquitous. Since I began working at a advertising company 5 years in the past, I’ve endured a every day onslaught of unasked-for emails—provides for leads, new software program demos, and web site backlinks.
Usually, I instantly delete these emails or mark them as spam. They litter my inbox, consistently clamoring to guide a demo or seize me for a fast chat. It’s annoying and the antithesis of my view of efficient advertising.
Then, in the beginning of 2025, I considered a greater use for these chilly emails—analysis. What if I collected these emails and studied their methods? What if I might expose the lazy patterns of chilly e-mail blasting and statistically display how ineffective (and aggravating) this follow is?
My methodology
I used to be remiss in having deleted all these spam emails for the final 5 years—all that juicy information misplaced. Nevertheless, I obtain such a quantity of chilly emails that it didn’t take lengthy to gather a brand new pattern of information to review. In lower than six months, I had over 700 emails to review.
My final massive advertising analysis experiment was executed completely manually. It took me hours to compile and analyze one piece at a time. To deal with this quantity, I turned to a brand new useful resource: LLMs. I compiled all these emails and outsourced the evaluation to ChatGPT 4o.
I created a brand new folder in Gmail to categorize the emails. Each time a brand new chilly e-mail hit my inbox, I tagged it. ChatGPT did the remaining, with my steering. I requested AI to jot down a customized script to construct a database from this Gmail folder. It scraped the information from every e-mail to gather sure fields:
- Ship date and time
- Topic line
- Sender’s identify and e-mail handle
- Physique of the e-mail and phrase depend
- Variety of emails from the identical sender
Then, I labored with the LLM to construct just a few extra subjective fields like:
- Tone of the e-mail
- Service providing
- In the event that they included a hyperlink, a P.S., or a name to motion
- In the event that they talked about my identify or firm identify
My Google Sheets script robotically scraped the folder every day and up to date the database. This gave me an prompt snapshot of what the emails contained. As a result of this was executed robotically and utilizing AI, I might add new information factors to reference and re-run the evaluation immediately.
The foundations
These are the principles I adopted to be as goal and truthful as attainable throughout this course of:
- Solely embrace emails that come on to my e-mail
- Open each e-mail to learn the contents
- Don’t click on on any hyperlinks or reply to any emails
- No generic e-mail newsletters—solely direct gross sales emails
- No clearly rip-off emails
- Can’t submit any lead gen varieties to set off an e-mail, as a result of then it’s not chilly outreach
My objective
I’ll admit it, I’m already biased towards chilly emails. So I by no means anticipated to evaluate whether or not or not they work. Information reveals that chilly emails form of work.
Research differ in outcomes: from a 30-50% response price (uncertain) to nearer to 1%. Even articles discussing the best way to do “higher” chilly emailing admit that “Nobody needs to ship them, nobody needs to obtain them.” The issue is that almost all of those research are executed by corporations that provide chilly outreach companies. They’re measuring by sending emails, not receiving them.
At scale, you’ll get just a few responses and perhaps just a few new gross sales. Nevertheless, this implies it’s important to harass (and threat pissing off) numerous extra individuals. What number of indignant potential prospects is one new buyer price?
Chilly emails have but to work on me. At finest, I ignore them. At worst, I mark them as spam after which write a complete analysis article exposing their practices.
My deeper query is what approaches do chilly outreach salespeople assume work. We’ll name it their “worst practices” (as a result of “finest practices” is simply too beneficiant). So I got down to gather as many chilly emails as attainable and establish conduct patterns and content material cliches.

The information
- 756 emails collected
- 180 days
- 4.3 emails per day
- 332 senders
I wished to have sufficient information to be statistically important. With ChatGPT’s enter, I decided that I wanted at the least 663 emails to succeed in a 99% confidence degree with a 5% margin of error. By gathering much more than that, we will confidently say this analysis means one thing.
You possibly can try your entire database your self at this hyperlink. (I’ll maintain gathering information in actual time even after this text is revealed, so the numbers could change barely over time.)
8 Classes from the information
1. A number of emails greater than half the time
54% of senders reached out greater than as soon as. The common variety of outreaches in a single thread was virtually three emails. Probably the most emails from a single particular person was 15.
A number of the frequent refrains in these fixed follow-ups included references to:
- My final/earlier e-mail (59 instances)
- My final/earlier message (37x)
- Getting in contact with another person on the firm (30x)
- Dropping into my inbox (17x)
- Not getting buried beneath different emails (16x)
They gained’t take no (or a chilly shoulder) as a solution.
2. Nearly all emails are predictably “personalised”
84% of emails had been personalised with my identify. 45% of the emails talked about my company identify (GreenMellen) in some unspecified time in the future. There are additionally a handful of instances I’ve been referred to as the mistaken identify (like George) or by the identify of the particular person sending the e-mail (I’m you, Joseph Wilson).
There have been additionally loads of random mentions of my job title, initiatives on our web site, or different meaningless items of data from my LinkedIn profile (“Congrats on that on-line certification you earned six years in the past!”). Loads of the non-public particulars had been simply mistaken—like the e-mail congratulating me on my first work anniversary once I’d been on the firm for over 4.5 years.
3. Emails are usually quick, however hardly ever candy
Even (most) chilly emailers know they don’t have your consideration for lengthy. The common phrase depend for the emails was simply over 180 phrases. The longest was 1,440 phrases; the shortest solely 18.
The automated script additionally included a rating for readability utilizing the Flesch Studying Ease rating. It’s a scale from 0-100, with the next rating being higher. The common readability of all of the emails was 47, which Flesch ranks as “very troublesome” to learn and equates to a 10-12 grade studying degree.
I additionally fed the textual content (greater than 125,000 phrases, or the size of a protracted fiction guide) right into a phrase cloud generator to detect the most-used phrases.
4. They use complicated topic strains to behave like clickbait
Topic strains are essential to e-mail open charges. As such, chilly emails overly prefer to personalize them—35% of the topic strains included my identify.
The common size of the e-mail topic strains was 5 phrases. The longest topic line was a whopping 40 phrases lengthy; and 22 of the emails had a topic line of solely a single phrase.
Identical to with the e-mail our bodies, I extracted all of the textual content and generated a phrase cloud.
Oh, and right here’s a listing of a few of my favourite, horrible topic strains:
- 60 minutes every day. Yours once more
- Need To Put This On Ice?
- one factor Robert
- Lets Strive That Once more
- Robert, are you able to deal with extra gross sales?
- Extra in your quiz: What Type of Mother Are You
- GreenMellen?
- You Deserve Higher
- it’s actually absurd Robert
Chilly e-mail topic strains are getting extra misleading – 35% embrace private names and plenty of use single-word clickbait techniques.
5. Their objective is to get you to reply, not click on
Solely about 37% of emails included a hyperlink. Normally, that hyperlink was to guide a calendar assembly with them, nevertheless it might additionally embrace examples of their work or backlinks they might promote me.
Solely 13% included a transparent name to motion, like reserving a gathering. Presumably, their major objective is so that you can reply to the e-mail (with out them mentioning it particularly—like a form of advertising inception) to point out curiosity. That’s how they hook you.
Talking of hyperlinks, solely 19% of the emails talked about an unsubscribe hyperlink. Technically, you’re supposed to incorporate one, however since I by no means subscribed to obtain their emails, they don’t should let me unsubscribe.
6. Over half of the emails are despatched within the morning
Greater than half (57%) of the chilly emails are despatched within the morning—between 6 am and midday. One other third (35%) was despatched within the afternoon, from midday to six pm. A small fraction was despatched exterior of that point—both the very early morning or late night. The hour with probably the most emails was 10-11 am.
This shouldn’t come as a shock. Most emails are despatched within the morning, and a fair bigger share in some unspecified time in the future through the work day. Most individuals aren’t checking emails commonly exterior of enterprise hours.
7. We now have totally different definitions of “worth”
As an excuse to maintain emailing me, they create many causes to comply with up. Apart from the empty ones like elevating their e-mail to the highest of my inbox, there have been fairly just a few “value-driven” emails—at the least useful to them.
These are among the most typical refrains from these emails (and what number of emails every phrase was talked about in):
- A fast chat (145) on Zoom (43)
- A assure (36) of ROI (66)
- Affords a present card (26)—often Amazon (14)
- Affords a demo (38)
- Free trial (6) with no obligation (16)
- Personalised Loom video (22)
- Some form of free obtain (11)
8. Utilizing chilly emails to promote… extra chilly emails
With so many emails, it’s simple to surprise what companies and merchandise these persons are really promoting. What are they pushing so onerous? Keep in mind I work for a advertising company, as a result of this actually shapes the form of provides I’m receiving.
I did a fast verify to see how usually a few of these phrases had been talked about within the emails:
- Adverts: 149
- Leads: 141
- AI: 106
- Video: 90
- SaaS: 83
- search engine optimization: 66
- Partnership: 27
- Backlinks: 18
- Sponsorship: 16
- Graphic design: 8
A lot of the lead era companies themselves are promoting extra chilly outreach. I suppose that is primarily simply individuals utilizing their very own instruments to promote the software. 41 emails particularly talked about “chilly emails” straight—discuss meta.
The opposite irony right here is that we had been usually provided companies we offer to our shoppers. There have been a handful of provides for web site growth, graphic design, and search engine optimization—all are companies we promote. Nothing extra tone deaf than providing to enhance the web site of a web site company.
Construct belief by permission-based advertising
As an alternative of interrupting prospects with undesirable messages, create useful content material that draws your splendid prospects and builds real relationships over time.
2 Explanation why you shouldn’t ship chilly emails
Individuals will nonetheless ship chilly emails—irrespective of what number of articles I write or chilly emails we ignore. For a lot of causes, however primarily as a result of they will. There’s nothing authorized stopping them.
My major argument towards chilly emails is that it’s completely unethical. It offers advertising a nasty identify and makes even legit channels tougher to succeed in individuals. Each chilly e-mail devalues belief in advertising—even for individuals who don’t follow it. But when the ethics argument labored, nobody could be sending chilly emails. We wouldn’t have to have this dialog.
As an alternative, I’ll attraction to their baser nature: outcomes. Even if you happen to ship the “finest” chilly e-mail, is it actually efficient whenever you’re taking part in in a poisonous atmosphere? If I get 5 chilly emails per day, I’m not going to reply to the one good one—I’m going to disregard all of them.
So please cease attempting to ship “higher” chilly outreach as a result of everybody round you is simply optimizing for scale, and shortly degrading high quality. Once you play that recreation, everybody loses.
