Email marketing remains one of the most effective digital marketing channels, delivering unparalleled ROI when executed correctly. Despite the rise of social media, messaging apps, and new platforms, email continues to provide a direct line to your audience — one that is fully owned and controlled by your brand.
However, the success of email marketing is not guaranteed. Businesses often struggle with low engagement, high unsubscribe rates, or poor deliverability because they ignore fundamental best practices. For businesses using Evershare, adopting email marketing best practices ensures campaigns are not just sent but received, opened, and acted upon.
This guide explores essential best practices across list management, content creation, personalisation, automation, and measurement — designed for modern marketers looking to optimise performance.
1. Build and Maintain a Quality Email List
Why a Quality List Matters
The foundation of any successful email campaign is a high-quality, permission-based list. Purchased or scraped lists result in:
-
Higher bounce rates
-
Increased spam complaints
-
Poor engagement
-
Risk of blacklisting
Email Marketing Best Practices for List Building
-
Use opt-in forms on websites, landing pages, and social channels
-
Offer value at signup (e.g., guides, webinars, exclusive content)
-
Use double opt-in to confirm interest
-
Regularly clean your list by removing inactive or invalid addresses
A clean, engaged list ensures your messages reach those who genuinely want to hear from you.
2. Craft Compelling Subject Lines and Preheaders
Your subject line is the first impression. Even the best content will fail if the email isn’t opened.
Subject Line Best Practices
-
Keep it under 60 characters for readability
-
Be clear, specific, and relevant
-
Avoid clickbait, which erodes trust
-
Personalise where appropriate (e.g., first name, location)
Preheader Best Practices
-
Use the preheader to complement the subject line
-
Provide a teaser or highlight value
-
Keep it under 100 characters
Effective subject lines and preheaders directly impact open rates and engagement.
3. Personalise Your Emails
Personalisation is a cornerstone of modern email marketing. Best practices include:
-
Using subscriber names, locations, or interests
-
Behavioural triggers (e.g., abandoned carts, page visits)
-
Lifecycle messaging (welcome sequences, re-engagement campaigns)
For example, a travel company could send a personalised email about a city a subscriber recently searched for, increasing relevance and conversion likelihood.

4. Optimise Email Content for Readability and Engagement
Even if your email is opened, poor content will fail. Best practices include:
Structure and Layout
-
Short paragraphs for easy scanning
-
Clear headings and bullet points
-
Visible call-to-action (CTA) buttons
Tone and Style
-
Keep a consistent brand voice
-
Be conversational yet professional
-
Focus on value, not promotion
Mobile Optimisation
-
Most emails are opened on mobile devices
-
Use responsive templates
-
Ensure clickable elements are large and accessible
5. Timing and Frequency
Finding the right cadence is crucial. Sending too often can lead to unsubscribes; too rarely, and your audience forgets you.
Timing Best Practices
-
Consider time zones of your subscribers
-
Test sending times (morning vs afternoon, weekdays vs weekends)
-
Leverage behavioural triggers to send when subscribers are most likely to engage
Consistency is better than frequency — maintain a predictable rhythm without overwhelming your audience.
6. Segment Your Audience
Segmentation improves relevance by sending targeted messages to different subscriber groups. Examples include:
-
Demographics (age, location, gender)
-
Purchase history
-
Engagement level
-
Preferences
Segmentation ensures subscribers receive content aligned with their needs, increasing engagement and loyalty.
7. Leverage Automation Wisely
Automation is essential for scaling email marketing without losing personalisation.
Key Automation Practices
-
Welcome series for new subscribers
-
Drip campaigns for onboarding or education
-
Re-engagement sequences for inactive users
-
Abandoned cart or follow-up emails
Automation frees up resources while maintaining consistency and timely communication.
8. Compliance and Privacy
Regulations like GDPR in Europe or PECR in the UK require transparency and consent.
Compliance Best Practices
-
Clearly communicate how subscriber data will be used
-
Provide easy opt-out mechanisms
-
Only collect necessary data
-
Store data securely
Compliant practices not only protect your business but also build subscriber trust.
9. Testing and Optimisation
Testing is key to continuous improvement.
A/B Testing Best Practices
-
Test subject lines, preheaders, and content variations
-
Compare CTA placement, copy length, and imagery
-
Use results to inform future campaigns
Optimisation should be ongoing; small adjustments can lead to significant gains.
10. Measure the Right Metrics
Focus on actionable metrics:
-
Open rate: indicates subject line effectiveness
-
Click-through rate: measures engagement with content
-
Conversion rate: shows ROI of campaigns
-
Bounce and unsubscribe rates: monitor list health
-
Revenue per email (if applicable)
Tracking these metrics allows marketers to refine campaigns and maximise ROI.
