📜 Best Practices for Email Marketing

📝 1. List Management

Effective email list management helps you maintain a healthy email list and ensures that emails reach the intended recipients.

✅ Regularly Clean Your List

• Remove inactive subscribers (e.g., those who haven’t engaged in 6+ months).
• Handle bounces by removing hard bounces and monitoring soft bounces for potential issues.

✅ Use Double Opt-In

• Confirm subscriptions via a double opt-in process where subscribers confirm their email address via Shape’s Lead Engine or lead funnels.

✅ Segment Your Audience

• Improve engagement by segmenting lists based on demographics, interests, and lead status for targeted campaigns.

✅ Provide Easy Unsubscribe Options

• Include a visible unsubscribe link in every email.
• Promptly remove unsubscribed users to prevent spam complaints and maintain compliance.

🔐 2. Email Authentication for Secure Sending

Email authentication verifies your identity as a sender and protects your domain from spoofing and phishing attacks.

🔹 Implement SPF (Sender Policy Framework)

✔️ Authorizes mail servers to send emails on behalf of your domain.
✔️ Prevents unauthorized senders from using your domain for spam.

🔹 Use DKIM (DomainKeys Identified Mail)

✔️ Adds a digital signature to emails to verify message authenticity.
✔️ Ensures emails are not altered in transit.

🔹 Enable DMARC (Domain-based Message Authentication, Reporting & Conformance)

✔️ Uses SPF and DKIM to verify email legitimacy.
✔️ Allows you to specify how to handle failed authentication (reject, quarantine, or allow).
✔️ Generates reports on email authentication activity.

✍️ 3. Content Optimization for Engagement

Optimizing your email content improves engagement and ensures messages reach inboxes instead of spam folders.

✅ Craft Compelling Subject Lines

• Keep it clear, concise, and relevant – avoid ALL CAPS and excessive punctuation ❌‼️
• Personalize with recipient details (e.g., First Name) to boost open rates.

✅ Balance Text & Images

• Maintain a good text-to-image ratio (some email clients block images by default).
• Use alt text to describe images in case they don’t load.

✅ Include a Clear Call-to-Action (CTA)

• Make CTAs visible, action-oriented, and easy to click (e.g., "Schedule a Call" or "Download Guide").
• Provide multiple clickable links for convenience.

✅ Optimize for Mobile 📱

• Ensure emails use responsive design to display correctly on all devices.
• Use larger fonts, concise content, and single-column layouts for better readability.

✅ Test & Analyze Results 📊

• Conduct A/B testing on subject lines, CTAs, and images to determine what works best.
• Track open rates, click-through rates, and conversions to improve performance.
