Email infrastructure

What is email infrastructure?

Email infrastructure is the underlying system that handles email sending, delivery, authentication, and tracking. It includes SMTP servers, IP reputation management, DNS configuration, bounce handling, and event processing. Building and maintaining it in-house is complex and time-consuming.

What SaaS teams face

• Building email infrastructure diverts engineering time from product features.
• Managing sender reputation, IP warming, and deliverability requires specialized knowledge.
• Compliance requirements (GDPR, data residency) add layers of complexity to self-hosted solutions.
• Scaling email sending alongside user growth requires ongoing infrastructure investment.
