Email marketing best practices worth keeping
Ten practical checks for audience permission, useful copy, reliable delivery, and measuring email without chasing open rates.
A polished email can still be a bad email. The offer may be irrelevant, the list may be stale, or the button may lead to a page that asks the reader to start over.
These are the checks we would keep even if the editor, sending platform, and design all changed.
Before the draft
- Know why each person is on the list. Keep the signup source and permission record. Exclude unsubscribed and suppressed contacts from marketing audiences.
- Choose the audience before writing the email. An update for active customers needs different context from a first message to new subscribers. Start with a few useful segments.
- Give the email one job. Write the intended action in the brief. If the team cannot agree on it, more copy will not solve the problem.
While editing
- Make the subject a fair description. Curiosity is fine. A fake reply prefix or invented deadline damages trust before the reader reaches the body.
- Put the useful information first. A customer looking for pricing, an event date, or a setup step should not have to scroll through a company introduction.
- Design for a narrow screen. Use readable text, buttons with enough space to tap, and a layout that still makes sense when images fail. Put essential information in text instead of baking it into a picture.
- Use only claims you can defend. A testimonial needs permission and a real source. A discount needs clear terms. A deadline needs an actual end date. AI-generated copy needs this review just as much as any other draft.
Before and after sending
- Test the exact version you will send. Check links, merge fields, the reply address, unsubscribe behavior, and a real inbox preview. A screenshot alone cannot prove that a link or personalized value works.
- Watch the audience as well as the campaign. Rising complaints or unsubscribes can mean the message, frequency, or signup promise is wrong. Sending more does not fix that mismatch. Read the deliverability guide before expanding volume.
- Measure the intended outcome. Track an activation, purchase, useful reply, or other relevant action, not open rates. Use A/B tests to answer a specific question, and accept an inconclusive result when the sample is small.
Keep the review short enough to use
A campaign brief can be five lines: audience, reason for sending, promised benefit, evidence, and next step. Attach the approved assets and any constraints. That gives a colleague or email agent something concrete to work with.
Brew can turn that brief into an email, but the review still belongs to the person sending it. The test is simple: would this email make sense to the person receiving it today?
