Subject: How we increased conversions 340% (real case)

Hi [Name],

Last week one of our clients asked us:
"Why don't my landing pages convert?"

We analyzed their page and found 3 critical errors:

ERROR 1: CTA not visible enough
- The button was gray on a light background
- Solution: High contrast + action text

ERROR 2: Too many form fields
- Asked for 8 fields to download an ebook
- Solution: Only email and name

ERROR 3: No social proof
- No testimonials or client logos
- Solution: We added 3 logos and 2 testimonials

RESULT: Conversion went from 2.1% to 9.3%

Best Practices for Newsletters

1. Effective Subject Line

The subject line determines if your email gets opened or ignored.

Formulas that work:

Avoid:

• ALL CAPS
• Too many emojis
• Spam words (FREE!!!, Urgent!!!)
• Misleading subjects

2. Email Structure

1. HOOK (First 2 lines)
   - Capture immediate attention
   - Answer "why should I read this?"

2. BODY (Main content)
   - One topic per email
   - Short paragraphs (2-3 lines)
   - Bullet points for scanning

3. CTA (Call to action)
   - One main CTA per email
   - Visible and clear button
   - Action text ("Download now", not "Click here")

4. CLOSING (Signature + P.S.)
   - Personal signature, not just logo
   - P.S. with second CTA or reminder

3. Frequency and Timing

Recommended frequency by type:

Best days and times:

Best time: 10:00 AM recipient's local time

4. Personalization

Not just the name. Personalize by:

TypeScript
// Basic: Name only
const basic = Hi ${name},;

// Intermediate: Name + behavior
const intermediate = Hi ${name},
we noticed you were interested in our article about ${lastArticleRead}.;

// Advanced: Segment + history + preferences
const advanced = Hi ${name},
As a ${role} in ${industry}, we know ${painPoint} is a challenge.
That's why we created this guide specifically for you.;

5. Mobile Optimization

60% of emails are opened on mobile. Make sure to:

• Maximum width: 600px
• Font size: Minimum 16px
• Buttons: Minimum 44x44px (touch area)
• Images: Always include alt text
• Preheader: Complement the subject (first 100 characters)

Sending Newsletters with Zavu

Initial Setup

TypeScript

const client = new Zavu({
  apiKey: process.env.ZAVU_API_KEY,
});

Send Simple Newsletter

TypeScript
async function sendNewsletter(
  subscribers: Array<{ email: string; name: string }>,
  subject: string,
  htmlContent: string
) {
  const results = await Promise.all(
    subscribers.map((subscriber) =>
      client.messages.send({
        to: subscriber.email,
        channel: "email",
        subject: subject,
        text: extractTextFromHtml(htmlContent),
        htmlBody: htmlContent.replace("{{name}}", subscriber.name),
        replyTo: "newsletter@yourcompany.com",
      })
    )
  );

  const sent = results.filter((r) => r.message.status === "queued").length;
  console.log(Newsletter sent to ${sent}/${subscribers.length} subscribers);

  return results;
}

Segmented Newsletter

TypeScript
interface Subscriber {
  email: string;
  name: string;
  segment: "new" | "active" | "inactive";
  interests: string[];
}

async function sendSegmentedNewsletter(subscribers: Subscriber[]) {
  const templates = {
    new: {
      subject: "Welcome! Your getting started guide",
      template: "welcome-newsletter",
    },
    active: {
      subject: "This week at [Company]",
      template: "weekly-newsletter",
    },
    inactive: {
      subject: "We miss you - See what you missed",
      template: "reengagement-newsletter",
    },
  };

  for (const subscriber of subscribers) {
    const { subject, template } = templates[subscriber.segment];

    await client.messages.send({
      to: subscriber.email,
      channel: "email",
      subject: subject,
      htmlBody: await renderTemplate(template, {
        name: subscriber.name,
        interests: subscriber.interests,
      }),
      metadata: {
        segment: subscriber.segment,
        campaign: "weekly-newsletter-2025-01",
      },
    });
  }
}

Webhook Handling for Metrics

TypeScript
app.post("/webhooks/email", (req, res) => {
  const { event, data } = req.body;

  switch (event) {
    case "message.delivered":
      await trackMetric("delivered", data.messageId);
      break;

    case "message.opened":
      await trackMetric("opened", data.messageId);
      break;

    case "message.clicked":
      await trackMetric("clicked", data.messageId, data.url);
      break;

    case "message.bounced":
      await handleBounce(data.to, data.bounceType);
      break;

    case "message.complained":
      await handleSpamComplaint(data.to);
      break;
  }

  res.sendStatus(200);
});
