Email Marketing Best Practices

Crafting effective campaigns and managing subscriptions

Updated this week

This article outlines essential strategies to create impactful email campaigns and manage subscriptions effectively. By following these best practices, you can improve email deliverability, engagement, and maintain a positive reputation as an email sender.

Avoid Spammy Content

Crafting professional, engaging, and compliant email content ensures that your messages avoid spam filters and connect effectively with your audience.

  • Write Clear, Relevant Content: Avoid excessive capitalization, exclamation points, or gimmicky phrases like “FREE!!!” or “ACT NOW.” These can trigger spam filters and diminish your credibility. Instead, focus on creating compelling subject lines and engaging content that aligns with the recipient’s needs.

  • Separate Content Types: Understand the distinction between transactional emails (individual notifications) and marketing campaigns (bulk emails requiring opt-in). Avoid combining different types of content in the same email, such as mixing promotions with sales receipts. For more information, please see our article "Understanding Transactional vs. Marketing Emails."

  • Maintain a Balanced Format: Ensure a healthy image-to-text ratio in your email designs. Emails with too many images or too little text are more likely to be flagged as spam.

  • Avoid Spoofing: Never impersonate another domain or sender without explicit permission. This practice can harm your sender reputation and lead to your emails being marked as fraudulent.

Permission-Based Marketing

Building and maintaining a permission-based email list is critical for compliance and recipient engagement.

  • Build Your List Organically: Avoid purchasing email lists, which often result in high spam complaints and poor engagement. Instead, use lead-generation tools, sign-up forms, and customer interactions to grow your audience. Avoid sending emails to individuals who have not explicitly signed up to receive messages from you.

  • Re-Engage or Remove Inactive Subscribers: Periodically review your email list and either re-engage unresponsive subscribers with targeted campaigns or remove them. A cleaner list improves deliverability rates and reduces bounce rates.

  • Comply with Regional Laws: Ensure your sign-up processes and email content meet regulations like GDPR, CASL, and CAN-SPAM. Avoid pre-checked opt-in boxes and provide clear consent mechanisms.

Leverage Segmentation Strategies

Segmentation allows you to deliver personalized content tailored to specific audience groups, driving higher engagement.

  • Behavior-Based Segmentation: Group recipients based on their interactions with your business, such as attending a webinar or inquiring about specific services.

  • Demographic Segmentation: Use attributes like age, location, or industry to create targeted campaigns. For example, localize offers for specific regions.

  • Lifecycle Stages: Customize emails based on where recipients are in their customer journey, such as onboarding for new leads or exclusive offers for loyal customers.

Optimize Timing and Frequency

The timing and frequency of your email campaigns play a crucial role in their success.

  • Send Emails at Optimal Times: Use data analytics to determine when your audience is most likely to open and engage with your emails. Testing different times can help identify patterns.

  • Avoid Over-Mailing: Sending too many emails can overwhelm recipients, leading to unsubscribes or spam complaints. Balance frequency with the value of your messages to maintain trust and engagement.

Manage Your Email List Effectively

A clean and well-maintained email list is vital for deliverability and engagement.

  • Update Your List Regularly: Remove invalid or unengaged email addresses to maintain list health and improve open rates.

  • Use Double Opt-In: Implement a confirmation process during sign-up to ensure email addresses are valid and that recipients genuinely want to hear from you. This ensures the validity of email addresses and prevents spam traps from entering your list.

  • Provide a Simple Unsubscribe Option: Ensure recipients can easily opt out of your emails. This not only builds trust but also prevents recipients from marking your emails as spam.

  • Reduce Spam Complaints: Send emails only to those who have opted in and ensure your content is relevant to their interests. Targeted, engaging campaigns are less likely to be flagged.
