Question 1

What is the average ROI for email marketing?

Accepted Answer

Email marketing consistently delivers the highest ROI of any marketing channel. The industry benchmark is $36–$42 return for every $1 spent (3,600–4,200% ROI). For perspective, Google Ads averages 200% ROI and social media averages 95% ROI. Email's high ROI comes from low cost per send, owned audience (no algorithm dependency), and high buyer intent from subscribers.

Question 2

What is a good email list conversion rate?

Accepted Answer

A good overall conversion rate (opens × clicks × purchases) for ecommerce is 0.1–0.3% of total list per campaign. Breaking it down: 25% open rate × 3% CTR × 2% conversion = 0.0015 = 0.15% of list converts per email. High-performing lists achieve 0.3–0.5% overall conversion. The biggest lever: improving your open rate through better subject lines and send-time optimization.

Question 3

How often should I email my list?

Accepted Answer

Optimal email frequency varies by audience type: E-commerce: 2–4 emails/week for active buyers, 1/week minimum, Weekly newsletter: 1/week consistently (consistency beats frequency), B2B SaaS: 2–4/month for nurture sequences, High-engagement list: can go daily with valuable content. Warning: under-emailing (less than 1/month) increases list decay — subscribers forget who you are and unsubscribes spike when you do send.

Question 4

What email metrics should I track?

Accepted Answer

Primary: Open rate (aim 25%+), Click rate (aim 2–4% of list, 8–15% of openers), Revenue per email sent ($0.05–$0.30 for ecommerce). Secondary: Unsubscribe rate (under 0.3% = healthy), Bounce rate (under 2% = healthy), List growth rate (track monthly net growth). Advanced: Revenue per subscriber (tracks list monetization efficiency), Deliverability rate (aim 95%+, below 90% means spam issues).

Question 5

How do I increase my email open rate?

Accepted Answer

Highest-impact open rate tactics: (1) Subject line testing — 4–5 variations, use curiosity or specificity (not clickbait), (2) Preview text optimization — often ignored but seen before opening, (3) Send time personalization — Klaviyo and ActiveCampaign offer ML-based optimal send times, (4) List hygiene — remove unengaged subscribers every 6 months (smaller engaged list beats large disengaged list), (5) From name — first name from person, not brand, typically outperforms.
