Here’s a great way to add stopping power to your headline copy.
Paraprosdokians turns of phrase in which the latter part of the sentence isn't what you expected based on the first part of the sentence. They encourage you to re-think the entire statement – which is exactly what you want folks to do when they read and engage with your copy. Here are some of the more famous ones.

I love this C.P. D.M. promotion for a few reasons.
It reminds us that a hand-written note is still a very affordable gift to someone, and for the recipient a keep-sake that will be probably be kept a lot longer than a text message or an e-mail (along with special birthday and x-mas cards).
It reinforces the Canada Post brand’s value at a time when many boxes delivered by C.P. are branded Amazon.
For Canada Post it’s a VERY affordable test given they own the infrastructure.
Response rates are very simple and easy to track right down to FSA.
It reminds household residents who received this piece and are employed in an advertising or marketing capacity that Canada Post DM is a VERY smart and VERY viable alternative to unaddressed mail and online marketing.
Lets hope Canada Post remembers another core rule of DM: message frequency. Make sure this is not the 1st and last reminder.

Colman George de Souza, of Burlington, Ontario passed away on April 13, 2021 at the age of 84. Just like he dealt with all experiences in life, Colman faced life and death with strength and grace, and wanted to spend as much time with his loved ones as possible.
He leaves behind his devoted wife and family.
Colman was born in Rangoon, Burma and emigrated from Karachi, Pakistan to Canada in 1966. He lived in Markham, Ontario for 40 years, where he was a devoted Eucharistic Minister at St. Patrick’s Parish. He directed advertising and marketing research with Grant Advertising, Foster Advertising, the Financial Post, and the National Post, from where he retired in 2000 as Vice-President of Media and Director of Research.
Colman was the life of their many parties, and made friends everywhere he went. We will never forget the anniversary dinners, the SYP, the Sarasota Six, and nights of bridge and investing advice. He was an avid photographer, stamp collector, and gardener. He loved trains, birds, music, and a good glass of scotch, most often shared with his brother Eden.
He and his wife traveled the world.

"Harmony" is core to all of my integrated communication designs. The work is in harmony when internal communications compliment the customer facing material. Together operations and communications build and support the brand proposition and promise that support other mission critical intangibles like love and trust.
I work to to minimize "Cognitive Dissonance". To learn how Cognitive Dissonance builds or breaks the brand bond in advertising, keep reading.
Cognitive dissonance (Source: Wikipedia™)
Cognitive dissonance is a term used in modern psychology to describe the feeling of discomfort when simultaneously holding two or more conflicting cognitions: ideas, beliefs, values or emotional reactions. In a state of dissonance, people may sometimes feel "disequilibrium": frustration, hunger, dread, guilt, anger, embarrassment, anxiety, etc. The phrase was coined by Leon Festinger in his 1956 book When Prophecy Fails. It is one of the most influential and extensively studied theories in social psychology.
The theory of cognitive dissonance in social psychology proposes that people have a motivational drive to reduce dissonance by altering existing cognitions, adding new ones to create a consistent belief system, or alternatively by reducing the importance of any one of the dissonant elements. It is the distressing mental state that people feel when they "find themselves doing things that don't fit with what they know, or having opinions that do not fit with other opinions they hold." A key assumption is that people want their expectations to meet reality, creating a sense of equilibrium. Likewise, another assumption is that a person will avoid situations or information sources that give rise to feelings of uneasiness, or dissonance.
Cognitive dissonance theory explains human behavior by positing that people have a bias to seek consonance between their expectations and reality. According to Festinger, people engage in a process he termed "dissonance reduction", which can be achieved in one of three ways: lowering the importance of one of the discordant factors, adding consonant elements, or changing one of the dissonant factors. This bias sheds light on otherwise puzzling, irrational, and even destructive behavior.
