Email marketing is most effective when your subscribers understand why they receive your emails.
Some emails should help them learn something useful. Some emails should help them make a decision. Some emails should lead them straight to the offer.
If every email is promotional, subscribers may feel like you only contact them when you need something. If every email is informative but lacks any call to action, they may stay engaged but won’t take a step further.
The right balance is about knowing what role each email should play.
Value is not the opposite of selling
Value and promotion should not be treated as mutually exclusive.
An email with value can make someone ready to buy. A promotional email can also be valuable. The difference is whether the email helps the reader understand something more clearly.
Value can help readers understand a problem, compare solutions, avoid mistakes, or feel more confident about their needs. This gives context to the offer before it is presented.
A sales email can also provide value when it explains who the offer is for, what is included, why it is useful, and what the reader should do next.
Use the 80/20 rule as a guide
The 80/20 rule is often used as a simple guideline: around 80% of emails provide value, while around 20% are more directly promotional.
This is helpful, but not strict math. The right balance depends on the business, audience, buying cycle, and season. Some businesses can promote more during busy periods. Others need more trust-building before asking someone to buy.
Instead of applying the ratio literally, ask yourself questions such as:
- Do we give our audience a reason to continue reading?
- Are our offers specific enough?
- Does each email have a purpose and value for the reader?
The goal is to give your audience enough value to stay interested and enough promotion to understand what actions to take.
Decide what type of value the reader needs
Value does not always mean education. Many businesses assume that all non-promotional emails need to teach something new, which can make the newsletter feel repetitive.
Value can also come from a reminder, comparison, customer example, simple explanation, answer to a common question, or guidance before making a decision.
What kind of value to provide depends on the needs of the reader.
New subscribers may require more clarity, while those who already understand the problem may need proof. Ready to buy subscribers may need help choosing the right option.
Value in emails should not just be there to fill up the space. Rather, it should increase the reader’s level of knowledge, interest or readiness for future action.
Do not hide the offer for too long
Balance also means knowing when to move from helpful content into promotional one.
Some businesses give value for a long time but don’t make any direct offers. They send tips, ideas, and advice, but never clearly explain what product would solve the problem or how someone can work with them.
That way, subscribers may engage with the emails, but still not know what service is available to book, or what product is relevant.
Promotion is not something to avoid. When promotional emails are introduced at the right time, they help connect the value you’ve been sharing to a specific offer that the reader can consider.
Let engagement shape the balance
The right balance is not the same for every audience.
Some subscribers respond well to frequent offers. Others need more time, context, or proof before they are ready to act.
That is why it helps to pay attention to behaviour, not only the email calendar. Useful signals include clicks, replies, visits to booking or sales pages, purchases, enquiries, and unsubscribes.
If people engage with helpful emails but ignore promotional ones, the offer may need better framing. If they click on offer-related emails, they may be ready for more direct promotion. If unsubscribes rise, the frequency may need to shift.
Plan campaigns, not individual emails
Balance is much simpler when emails are planned as part of a campaign, not as separate emails sent whenever something needs to be announced.
The campaign assigns a role to each email. One email could be used to explain the problem. Another could respond to a frequently asked question. Another could share proof. Another could present the offer.
This makes promotion feel more natural because by the time it appears, the reader already understands the context behind it.
Final thoughts
The right balance between value and promotion is not about following a ratio. It is about keeping your emails useful, but at the same time ensuring that the readers have a clear path forward.
Value allows you to keep your audience engaged in your business, while promotion explains to them what actions they can take.
Purposeful planning of both aspects improves the effectiveness of email marketing.
