📚 Email Deliverability Guide

Mastering email deliverability ensures your messages reach the inbox, not the spam folder. Here are the core pillars:

1. Authentication (SPF, DKIM & DMARC)

Authentication proves to mailbox providers that you are a legitimate sender. It's non-negotiable for good deliverability.

• SPF (Sender Policy Framework): A DNS record listing all servers authorized to send email from your domain.
• DKIM (DomainKeys Identified Mail): Adds a digital signature to your emails, verifying they haven't been altered in transit.
• DMARC (Domain-based Message Authentication): Tells servers what to do with emails that fail SPF or DKIM checks and provides reporting.

2. Sender Reputation

Your sending domain and IP address have a reputation score. High complaint rates, sending to invalid addresses (high bounces), or hitting spam traps will damage your reputation. Maintain a clean list and monitor your sending metrics.

3. Content Quality

Your email's content is heavily scrutinized. Avoid spam trigger words (e.g., 'free', 'urgent', 'winner'), excessive capitalization, too many links, and large images. Always provide value and include a clear unsubscribe link. Test your emails before sending to large lists.

4. List Hygiene

Regularly clean your email list by removing inactive subscribers, invalid addresses, and those who haven't engaged in 6+ months. This improves your sender reputation and engagement rates.

5. Engagement Metrics

Email providers track how recipients interact with your emails. High open rates, click rates, and low spam complaints signal quality content and improve deliverability.
