Frequently Asked Questions
You can start earning with as few as 100 highly engaged subscribers. The key is quality over quantity. A list of 100 subscribers who open and click regularly can generate $100-300/month with the right offers. Focus on engagement metrics first, then scale.
Frequency depends on your niche and content: News/updates niches: 3-5x/week | Educational content: 2-3x/week | High-ticket/considered purchases: 1-2x/week. The golden rule: Send as often as you have valuable content. Never send just to "stay in touch."
The 80/20 rule works well: 80% valuable content (education, entertainment, inspiration) and 20% promotional (affiliate offers, product recommendations). For newer lists (under 1,000 subscribers), aim for 90/10. For highly engaged lists (50%+ open rates), you can test 70/30.
1) Maintain high engagement rates (opens/clicks), 2) Use double opt-in, 3) Clean your list regularly (remove non-engagers), 4) Avoid spam trigger words ("free," "buy now," etc.), 5) Use a reputable email service provider, 6) Authenticate your domain (SPF, DKIM, DMARC), 7) Warm up new IP addresses gradually.
Test for your specific audience, but general best practices: B2C: Tuesday-Thursday, 10AM-2PM local time | B2B: Tuesday-Thursday, 8-11AM local time | Weekends: Sunday evenings work well for some niches. Use your email platform's send time optimization feature for best results.
Start with free plans (MailerLite, Mailchimp) or low-cost plans ($10-29/month). Invest in tools as you grow: 0-500 subscribers: $0-29/month | 500-5,000 subscribers: $29-99/month | 5,000-50,000 subscribers: $99-299/month. The ROI should justify the cost—aim for at least 5x return on tool investments.
