3 examples of a good advertising email
A good advertising email is one that gets opened, read and clicked. Most end up ignored, for lack of structure and a clear message. Here are three advertising emails that work, with what makes them effective — to inspire you in your own campaigns.
Before the examples, let's keep in mind what sets a good advertising email apart from one that ends up in the trash: a subject line that makes you want to open, a single clear objective, a short, benefit-oriented message, and an obvious call to action. These principles run through the three examples that follow.
What makes a good advertising email
It all starts with the subject line: it's what decides whether the email is opened or not. A good subject is short, intriguing or carrying a clear benefit, and honest (nothing worse than a misleading subject). Then, the body must get straight to the point: a single message, a single objective, and a single, visible call to action. An email that asks for ten things gets none of them.
Add to that easy reading on mobile (most emails are read there), a human tone and a touch of personalization. These foundations apply to all types of emails; now let's look at three examples that apply them to different objectives.
Example 1: the limited-time offer
It's the classic advertising email: a clear promotion with a deadline. For example, a subject like “20% off until Sunday only,” an attractive visual, a sentence presenting the offer, and a big “Get the deal” button. What makes it effective is the combination of a concrete benefit (the discount) and urgency (the deadline), which pushes people to act right now rather than “later.”
The key is simplicity: a single offer, a single button, zero distractions. The frequent mistake is overloading this type of email with several promotions; you then dilute attention and the click rate drops. One offer, one deadline, one action.
Example 2: the welcome email
When someone subscribes to your list, the welcome email is one of the most opened of all: it's the moment when interest is at its peak. A good example thanks them warmly, briefly introduces who you are and the value the person will receive, and often offers a small incentive (a welcome code, a free guide) to kick off the relationship.
What makes it effective is that it turns a simple subscriber into an engaged potential client, from the first contact. It sets the tone, creates a good first impression and invites a gentle first action. Neglecting this email means missing the window when your audience is most receptive.
Example 3: the value email (content before the sale)
The best advertising email doesn't always look like an ad. The value email gives something useful — a tip, a trick, relevant content — before asking for anything. For example: “3 mistakes that make your clients flee (and how to fix them),” with genuinely useful content, and a discreet call to action at the end toward your service.
What makes it effective is the trust it builds: by helping first, you become a credible reference, and the sale follows naturally. This “give before you ask” approach builds loyalty and avoids the fatigue of repeated promotions. It's often the most profitable type of email over time.
The three examples share the same foundations: a subject that makes you want to open, a single objective, a clear call to action and a human tone. The difference lies in the intent — sell fast, welcome, or build trust.
The mistakes to avoid
A few traps weigh down even a good email: a misleading subject (which destroys trust), too many objectives at once, a buried or absent call to action, an unreadable design on mobile, and sending too frequently, which wears out your list. Every email should have a clear reason to exist for the recipient, not just for you.
Finally, measure: open rate, click rate, conversions. It's by observing what works that you improve your campaigns. Email remains one of the most profitable channels, provided you respect your audience's attention and trust.
Email, one channel among others
The advertising email is powerful, but it has a limit: it addresses people who already know you (your list). To grow that list and attract new clients, you first have to be found. That's where SEO comes in: being visible on Google at the moment clients are searching for your service.
At Ton Consultant, we help businesses attract these new clients through SEO, which then feeds all your other channels, including email. A good email converts; good visibility fills your list with people to convert.
The legal steps launch your business; it's visibility that keeps it alive. When your future clients search for your service on Google, that's where everything is decided. We're an agency 100 % focused on SEO: we help you show up at the right moment, in front of the right people, in your region.
