Why This Guide Matters
Email deliverability can make or break your digital communication strategy. With over 300 billion emails sent daily and 20% of commercial emails never reaching the inbox, mastering deliverability isn’t just nice to have—it’s essential. Poor deliverability costs businesses an average of $14,000 per year, while proper email marketing can deliver an ROI of 36:1.
