In sintesi

Email deliverability is the discipline of ensuring marketing and transactional emails reach user inboxes. It combines technical (SPF, DKIM, DMARC, sender reputation), platform (SendGrid, Mailgun, AWS SES), and content knowledge. A 5% improvement in inbox placement = 50+ additional conversions per 10k sends. Time to competency: 4-6 weeks for marketers, 2-3 weeks for engineers. Specialists earn 15-25% premium because they unblock critical revenue streams and fix multi-million-dollar list decay.

Cos'è Email Deliverability Optimization

Email deliverability is the practice of ensuring emails land in users' inboxes, not spam/promotions folders. It combines authentication protocols (SPF, DKIM, DMARC), infrastructure management (warm-up, IP reputation), content best practices, and list hygiene. Inboxes are gatekept by ISPs (Gmail, Outlook, Yahoo) using machine learning filters. Those filters evaluate sender reputation, authentication signals, content, and user engagement. Optimize all four, and you achieve 95%+ inbox placement. Ignore any one, and your emails get filtered.

❓ Domande frequenti

What's the difference between delivery and deliverability?
Delivery = email reached the ISP (Gmail, Outlook, etc.). Deliverability = it reached the inbox, not spam/promotions folder. You can have 99% delivery but 50% inbox placement. Deliverability is the harder problem.
What does SPF do? Do I need DKIM and DMARC too?
SPF confirms you own the sending domain. DKIM cryptographically signs each email. DMARC tells ISPs what to do if SPF/DKIM fail. Together, they prove you're not spoofing. All three are now required by Gmail/Yahoo (2024+) for senders with >5k emails/day.
How long does a new sending domain take to warm up?
2-4 weeks. Start with low volume (100 emails/day) and gradually increase 10-15% per day. ISPs monitor your reputation. Ramping too fast triggers spam filters. Patience pays off with clean reputation.
What causes emails to land in spam even if SPF/DKIM/DMARC are correct?
Content. Spam trigger words (FREE, URGENT, BUY NOW), suspicious links, image-only bodies, unknown senders. Also: list quality (high bounce rates tank reputation), engagement (low open rates signal spam), and sending to inactive users.
How do I audit why an email went to spam?
Use Google Postmaster Tools and Mailbox Providers' feedback loops (JMRP for Gmail, FBL for others). They tell you bounce/complaint rates. Send test emails to addresses you control (Gmail, Outlook, Yahoo) and check spam folders manually. Use mail-tester.com for scoring.
