We’ve all been there: your finger hovers over the ‘send’ button’, your heart skips a beat, and one question lingers—“Is this perfect?”In email marketing, the difference between a campaign that soars and one that flops can be as small as a broken link or a typo. At PostyMan, we believe preparation is the key to performance. This isn’t just a checklist—it’s your pre-flight ritual to make sure every email you send delivers results.
Your 10-Step Send-Button Sanity Check

1. Subject Line & Preheader
Your subject line is the first thing subscribers see. Make it magnetic, spark curiosity or urgency, and pair it with a strong preheader. This tiny bit of text can make or break your open rate.
2. From Name & Reply-To
Trust starts here. Make sure your sender name is recognizable, like “PostyMan” or “Jess at PostyMan,” and your reply-to address is actively monitored. An unfamiliar sender can send your email straight to spam.
3. Proofread Everything
Typos kill credibility. Read your copy carefully—then read it backward to catch errors your brain might auto-correct. A second pair of eyes never hurts.
4. Test Every Link
A broken link is a broken promise. Click every CTA, social icon, and even the “unsubscribe” link to ensure they lead to the right page.
5. Personalization Check
Personalization is powerful when done right. Test all merge tags (“Hi Sarah!”) to make sure no one sees placeholders like “Hi FNAME.”
6. Mobile Optimization
Your subscribers open emails on phones, tablets, and desktops. Preview on all devices to ensure your email looks perfect everywhere.
7. Image Optimization
Compress images for fast loading, keep them high-quality, and add descriptive alt text. This ensures your message gets through even if images are blocked.
8. A/B Testing
Test subject lines, CTAs, or content blocks on a small audience. Data-backed decisions help you continuously improve your email performance.
9. Audience Segmentation
Sending the wrong email to the wrong audience is wasted effort. Double-check your lists and segments to deliver relevant content.
10. Final Test Send
Do a full test send to yourself and your team. Review your email exactly as your subscribers will see it. Catch last-minute errors before it goes live.
