AWS Account with Port 25 Open
Send email directly from AWS — SMTP unblocked and ready.
By default, AWS blocks outbound port 25 (SMTP) on new accounts to prevent spam, requiring a support request to unlock. For developers who need to send email directly from EC2 — mail servers, transactional email, notification systems — this restriction is a roadblock. Our verified AWS accounts give you the compute and access you need, and our team can advise on the fastest path to outbound email. If your priority is guaranteed open port 25, we also recommend DigitalOcean open-port-25 accounts as a faster alternative.
