1. Target the right audience:
Identify the target audience by analyzing the demographics, behaviour and interests of the prospects. Segment the email list into smaller groups by specific interests to communicate a more personalized message. Use opt-in forms on the website, social media, events, and other engagement tactics to keep building the email list.

2. Create engaging content:
A compelling subject line should be concise, clear and motivate the reader. Use a tone of voice that fits the brand and the target audience. Always put the most important information first in the email. Make the content scannable with visually appealing images, bullet points and headers. Keep the call-to-action clear and easy-to-find.

3. Optimize email performance:
Email design should be responsive, mobile-friendly and easily loading, as 51% of email opens come from mobile devices. Control the email frequency and schedule them at the right times, test A/B variations and measure the performance metrics, such as (i) open rates, (ii) click-through rates, (iii) bounce rates, (iv) conversion rates, and (v) unsubscribe rates.

Google Analytics and other measurement tools help track the website traffic and conversions generated by the email campaign. Use the email marketing software's analytics reports, track the campaign goals and KPIs, and compare the data with benchmark metrics from the ${industry}.

5. Adjust strategies accordingly:
Based on the analytics data, optimize the email campaign for higher ROI by adjusting the content, improving the design, re-testing the email frequency, updating the email list, changing the call-to-action, or testing new automation tactics to nurture leads and increase customer loyalty.

6. Advice on common pitfalls and etiquette:
Avoid common email mistakes, such as using "spammy" subject lines, sending unsolicited emails, getting blacklisted, or violating the email privacy laws.
