Plan the Email Campaign Before You Write the Emails

By Ashley Kays ·

The most useful starting point is the customer decision you want to support. Define the audience, offer and next action before asking anyone—or AI—to write subject lines.

Give the campaign one primary job

A launch helps people understand a new product. An educational campaign helps them use or choose something. A promotion explains an actual offer to people for whom it is relevant. Decide which job matters most, then choose a primary customer action you can observe.

“Increase engagement” is difficult to evaluate. “Help existing owners find the compatible refill” is more concrete. You can check whether the information is clear, the destination is useful and the resulting orders contribute enough after costs.

Define who should receive it—and who should not

Describe an eligible audience rather than defaulting to the whole database. Consider product ownership, expressed interests and the customer's place in the journey. Verify marketing eligibility and suppression status in the sending platform.

Review exclusions for recent purchases, unresolved support issues, returns and overlapping automated flows when they make the message inappropriate. A recent purchaser might welcome setup guidance but have little use for another message urging them to buy the same product.

Klaviyo documents including and excluding recipient groups, and its recent-purchaser guidance calls out determining recipients at send time for future campaigns. Check the equivalent behavior in your platform. A segment that was correct when you drafted the email may have changed by launch day.

Create a message sequence, not three repetitions

A practical draft sequence could introduce the relevant benefit, answer a choice question and resolve a remaining objection. Not every campaign needs all three messages. Sending frequency should reflect the audience, offer window and other messages already scheduled.

Write the purpose and call to action for each message before the subject line. The landing page should deliver the same promise. If the email explains compatibility, link to information that actually helps customers confirm compatibility rather than a generic homepage.

The email campaign planner builds a three-message brief with draft dates, content directions and review checks. You can download it and adapt it in your email platform. It does not schedule or send anything.

Use AI after the facts are approved

Provide the actual product facts, offer terms, brand voice and audience need. Ask for a subject, preheader, short body and one main action. Require missing information to be listed separately from the draft.

Review every claim and dynamic field. An assistant should not invent a deadline, customer testimonial, product benefit or delivery promise to make the message sound more persuasive. Keep subscriber records out of a drafting prompt when a description of the segment is enough.

Check the experience before sending

Follow every link on a phone. Test personalization fallbacks, the actual discount, stock availability and the unsubscribe experience. Confirm date and timezone settings, and check what happens if someone purchases between the first and second messages.

For a promotion, run the offer through the contribution calculator before approving it. More attributed orders can still produce less contribution if the incentive is expensive.

Decide how you will judge it

Record the primary action, cost definition and observation period before launch. Review relevant clicks, completed purchases and contribution alongside unsubscribes, complaints and support questions. Opens alone are not a reliable indication that someone wants to buy.

A platform's attributed revenue is a reporting result, not proof that all those orders were caused by the campaign. Use a suitable comparison where possible, keep audience differences visible and avoid turning one successful send into a universal rule.

Finish with one decision: keep the approach, change the audience or message, or stop. Save the evidence so the next campaign starts with something you learned.
