As the fictional sales sage (or sadist) known only as Blake once said, “ABC—Always, Be, Closing.”

While entertaining, Alec Baldwin’s character in Glengarry Glen Ross added gasoline to the fiery belief that aggressive tactics are commonplace, and compulsory, in sales. If you want to close, you need to be forceful.

But is that true? Where’s the data to back Baldwin up? Maybe ABC should stand for:


Outreach VP of Sales, Mark Kosoglow, wondered the same the thing—does adopting aggressive sales tactics in emails get results or should you be more socially mindful? It’s an age-old question, and one Mark has struggled to answer over his decades-long career.

We decided to say adios to ancient assumptions (Glengarry Glen Ross came out in 1992—feel old?) and double down on data by bringing in Outreach VP of Data Science, Pavel Dmitriev, and Yifei Huang, Data Science Manager, to help get to the bottom of Mark’s internal debate.

Which Mark is right—the pushy old school sales bro or the kind modern sales pro? Let’s find out.

Do you have to be aggressive to sell or does politeness pay off?

We analyzed 4,500 sales emails—half with aggressive copy, the other half leveraging more socially mindful messaging. First, we looked at response rates to determine which tactic racked up more replies.

Looks like Sales Bro was right. Or was he?

Looks like the deal dinosaur, Old School Sales Bro, was right. Or was he?

You see, a high response rate is great and all but what if the responses you’re getting are all unsubscribe requests? That’s where Intent Classification comes in, our process of detecting and examining whether replies are positive, objections, or unsubscribe requests using Natural Language Process (NPL) and Machine Learning (ML). That way you can understand whether all those replies you receive are good or bad for business.

So was the aggressive messaging with the high reply rate actually the right move? As Mark would say, “Ssshhh...Data Desk.”

Spv Sb Final Results

Data always wins, apparently. Politeness pays off, and the data backs it up.

Data always wins. While aggressive sales tactics may garner more replies, many of those are negative. You can’t come back from an unsubscribe; the game is over. Politeness really does pay off.


Looks like Southern Gentleman Mark was right. And here are the numbers to back it up:

Aggressive Email

Socially Mindful Email

1.9% Response Rate

1.1% Response Rate

25.6% Unsubscribe

9.6% Unsubscribe

61.6% Objection

59.6% Objection

12.8% Positive

30.8% Positive

Whether this test will do anything to change the belief that successful sellers need to use, to quote Old School Sales Bro, a “...powerful, authoritative, manly tone,” is yet to be seen. Hopefully, consultative and courteous sales tactics will no longer be the exception but the norm.
