About Coresender

Coresender is a cloud email delivery service that provides developers with a fast, reliable SMTP relay and email API for both transactional and marketing messages. It focuses on getting emails into inboxes quickly, with measured delivery times of just a few seconds across major providers like Gmail, Outlook, and Yahoo, making it ideal for time‑sensitive use cases such as password resets, order confirmations, and sign‑up verifications. Dedicated infrastructure and priority lanes ensure transactional traffic is never slowed by bulk campaigns, while detailed bounce management and reputation tools safeguard sender health over time. The core value proposition is to take the undifferentiated heavy lifting of email deliverability off engineering teams: Coresender offers separate sending accounts, dedicated IPs with automated warm‑up, SPF/DKIM/DMARC setup assistance, and granular analytics with per‑message timelines, events, and webhooks. Teams can see exactly what happened to each email—sent, delivered, opened, clicked, bounced, or marked as spam—for up to 60 days, enabling faster troubleshooting and optimization. AiDOOS acts as the execution and integration layer that embeds Coresender into the wider enterprise architecture. It designs the multi‑account and multi‑region strategy, manages domain and authentication governance, and implements integrations into product backends, CRMs, analytics platforms, and observability tools using the Coresender API and webhooks. AiDOOS also automates operational tasks such as key rotation, IP warming policies, routing between transactional and marketing accounts, and monitoring for anomalies in bounce or complaint rates. This combination lets organizations scale Coresender from a single product team utility to a standardized, enterprise‑wide email delivery backbone.

Challenges It Solves

  • In‑house SMTP servers are hard to scale, secure, and maintain.
  • Transactional emails arrive late or land in spam during high volumes.
  • Limited visibility into delivery, bounce, and complaint events for each message.
  • No unified API and monitoring layer for multiple apps and brands.
  • Complex SPF/DKIM/DMARC setup and sender reputation management.
