Q1: What technical steps do you take to prevent a newsletter from landing in Gmail's Promotions or Spam tab?

1. Set up strict SPF, DKIM, and DMARC DNS records with a dedicated custom domain. 2. Warm up new domain IPs gradually. 3. Avoid excessive image-to-text ratios and spam trigger words. 4. Prompt new subscribers in the welcome email to reply (e.g., "Reply with 'Yes' so Gmail knows we're friends"), which sends strong positive signals to Google's inbox filtering algorithm. 5. Automatically purge inactive subscribers who haven't opened in 60 days.

Q2: How do you calculate the sponsorship revenue potential of a newsletter with 20,000 subscribers?

If the newsletter has 20,000 subscribers and a 45% open rate, each edition gets 9,000 opens. At an industry-standard CPM (Cost Per Mille / 1,000 opens) of $50, one primary ad slot costs (9,000 / 1,000) * $50 = $450 per send. Publishing 2 editions a week with a primary and secondary sponsor yields over $4,500 (~₹3.75 Lakhs) per month in sponsorship revenue.
