A good newsletter can lose a reader before the first paragraph: an unclear subject line, a broken link or a button that is awkward to tap. This checklist is a practical final pass for a solo writer sending an email newsletter. It is not a promise of higher open rates or inbox placement.

Start with one job for this email

Finish this sentence before you check the formatting: “After reading this, the reader can ___.” If you cannot finish it without adding three more goals, remove something. A newsletter can contain several links, but the opening should make its main value obvious.

A worked example: fix the email before sending it

This is a fictional example, not a reported campaign result. Imagine a weekly newsletter for people who work from a small home office.

Before

Subject: Weekly update #12
Preview: View this email in your browser
Opening: Hi everyone, we have lots of exciting things to share this week.
Link: Click here

Nothing here explains what the reader gets. The link also gives no clue about its destination.

After

Subject: A 10-minute reset for a cluttered desk
Preview: Three small changes, using what you already own.
Opening: If your desk has become a storage shelf, start by clearing one working area. This week’s guide walks through a short reset without buying organizers.
Link: Read the desk-reset checklist

The revision names a concrete task, sets a boundary and makes the link understandable. The guide itself must genuinely support the ten-minute claim; otherwise, change the subject. Do not use a specific promise just because it sounds more clickable.

The pre-send checklist

1. Recipient list: Confirm the audience or segment. Exclude test contacts where appropriate and never add people who did not agree to receive the newsletter.
2. Sender and reply address: Use a recognizable sender name. Check where replies go, and make sure that inbox is monitored.
3. Subject and preview: Read them together. The preview should add useful context rather than repeat the subject. Check the actual inbox display; truncation varies by device and email app.
4. Opening: Put the useful point before housekeeping. Remove a generic welcome paragraph if it delays the promised information.
5. Every link: Open each destination, including images, buttons and footer links. Look for draft URLs, permission screens, outdated offers and accidental links to the editor.
6. Personalization: Check the fallback when a first name is missing. A test email may not reproduce a real subscriber’s merge fields; use your provider’s documented preview method.
7. Phone readability: Send yourself a test and open it on a phone. Check paragraph length, horizontal scrolling, tap targets and whether the main action is easy to find.
8. Images: Check the email with images unavailable. Essential meaning should remain in the text. Give informative images useful alternative text.
9. Facts and promises: Recheck dates, amounts, names and time zones. If a price or feature could change, verify it at its original source.
10. Footer and final audience: Check the unsubscribe path and the sender information required by your provider and applicable rules. Then check the audience and scheduled time once more before sending.

Use a two-pass test, not endless proofreading

Pass one is mechanical: links, names, dates, audience, reply address and footer. Pass two is a reader’s pass: open the test on your phone and ask whether the subject’s promise is fulfilled. Separating these jobs makes it easier to notice a broken destination without constantly rewriting the introduction.

After correcting a broken link or layout problem, send a fresh test. The old test in your inbox is not evidence that the edited version works. For a small list, testing your own common email apps is a useful start; it does not prove the layout works in every email client.

Keep a tiny send log

Record the issue, subject, intended audience, main link, test date and anything that went wrong. On the next send, start with the last issue’s mistake. If readers report that a link needed a login, for example, open the next destination while signed out. A repeatable check is more useful than adding another tool.

Ready to send? You should be able to explain the email’s purpose in one sentence, open every important destination and read the test comfortably on your phone. If one of those fails, fix that specific issue before sending.
