Common Use Cases

MVPs

Add application email without building mail infrastructure.

Early SaaS

Support account and product communications as users grow.

Growing Teams

Add marketing automation and larger sending capacity when needed.

Deliverability matters: SMTP infrastructure can support a strong sending program, but inbox placement cannot be guaranteed. Authentication, sender reputation, recipient consent, list quality, content, engagement and receiving-provider decisions also affect delivery.
