# Delivery Regions

Mailofly allows you to specify the geographic region used to relay your outbound email traffic and store related logs.

## Available Regions

* **US East (N. Virginia - `us-east-1`)**: Default primary infrastructure for North American traffic and global lowest-latency dispatch.
* **EU West (Frankfurt / Ireland - `eu-west-1`)**: Tailored for European Union organizations requiring GDPR data residency adherence for message logs, recipients, and bodies.
* **AP South (Mumbai - `ap-south-1`)**: Optimized for South Asian latency and Indian regulatory requirements.

## Configuring Domain Region

When creating a domain via dashboard or API, pass the optional `region` parameter:

```bash theme={null}
curl -X POST "https://api.mailofly.com/api/domains" \
  -H "Authorization: Bearer mf_live_..." \
  -d '{
    "name": "notifications.company.com",
    "region": "eu-west-1"
  }'
```
