Sender reputation affects whether your emails reach inboxes or get blocked. It’s a score based on how mailbox providers view your sending behavior, including email content, infrastructure, and user feedback. This hub explores how reputation is built and maintained across domains and IPs, and why it matters for deliverability.

You’ll find guidance on warming up new IPs to gain trust from providers, balancing message volume with sender capacity, and managing the impact of spam complaints. Decisions around shared versus dedicated IPs, throttling practices, and separating transactional from marketing streams all influence reputation over time.

Understanding how different providers weigh domain versus IP reputation—and what triggers sudden drops—helps you respond quickly. This hub also covers practical tools and techniques, including automated warm-up strategies, email verification integration, and reputation monitoring across major platforms.
