Email deliverability is crucial for SaaS businesses to ensure messages reach user inboxes and not spam folders, impacting user onboarding, activation, and retention.
Key factors influencing deliverability include sender reputation, authentication, bounce/complaint rates, message content, and engagement metrics.
Domain reputation, evaluated primarily at the domain level by mailbox providers, plays a significant role in email deliverability.
Best practices like email authentication (SPF, DKIM, DMARC), using a reliable email sending infrastructure, and gradually warming up new domains and IPs help improve deliverability.
Segmenting transactional and marketing emails, maintaining a clean and opted-in email list, sending relevant content, and encouraging engagement are recommended practices.
Monitoring sender reputation and performance continuously, aiming for high inbox placement rates, and using tools like Sidemail, Mailgun, SendGrid, or Amazon SES can enhance email deliverability.
A 'good' email deliverability rate varies but generally involves the vast majority of emails reaching inboxes, with rates above 90% considered very good and over 95% excellent.
Email deliverability is a mix of proper sending practices and using the right tools, emphasizing the importance of sender reputation and adherence to best practices for successful communication.
Understanding email deliverability fundamentals, building domain reputation, employing proper authentication, and user-focused communication are essential for fostering trust and engagement with users.
