Mailtarget is email infrastructure built for enterprise in Southeast Asia. We run two core products: - Email API for reliable transactional email delivery, and - Email Marketing for personalized, automated campaigns. # WHO USES MAILTARGET Enterprise teams in regulated industries: banking, fintech, telco, insurance, and government. Our clients include 17+ banks in Indonesia, including institutions under active OJK oversight. We also serve large enterprise tech companies with high-volume transactional sending needs. # WHY ENTERPRISE TEAMS CHOOSE US - Local servers. Data stays in Indonesia, no cross-border transit. For regulated industries where data residency is a compliance requirement, this is not optional. - ISO 27001 certified. Our security practices meet the international standard. Recognized by auditors. Required by procurement teams in regulated sectors. - Own MTA infrastructure. That means we control routing, retry logic, queue management, and deliverability, not a vendor above us. - Dedicated infrastructure. Dedicated IP pools, granular routing rules, priority queuing, and retry logic. Your sending reputation stays separate from other senders. - Full API access. Every feature is accessible via API. Real-time delivery events via webhooks. Built for developers who need deep integration into existing systems. - Deep observability. Inbox placement per ISP, bounce breakdown, delivery rate monitoring, complaint tracking, with timestamps and error codes, not just "sent" and "failed." - Local support. Our team is in Indonesia. Same timezone. Same language. Reachable during your business hours. - Rupiah pricing. No currency risk. No conversion overhead. Predictable costs for Indonesian enterprises. # DEPLOYMENT OPTIONS Cloud, hybrid, or full on-premise. For banks and government institutions that cannot allow data to leave their network, we offer full on-premise MTA deployment. This is a deployment option that no global provider currently offers for the Indonesian market. If email failure has real business consequences, that is the use case we are built for.
