Quolle Documentation

Transactional email API and SMTP relay built for African SaaS.
Naira pricing ยท AWS SES powered ยท NDPC compliant.

What is Quolle?

Quolle is a transactional email infrastructure built specifically for African developers and SaaS companies. Instead of paying in USD with US-centric compliance requirements, you pay in Nigerian Naira, operate under NDPC (Nigeria Data Protection Commission) guidelines, and get infrastructure optimised for the network conditions common across the continent.

Under the hood, email delivery is powered by Amazon SES โ€” one of the most reliable sending infrastructures in the world โ€” so your messages land in inboxes, not spam folders.

You can integrate via the REST API, the SMTP relay, or any HTTP client in any language. There are no special SDKs to install.

Key features

Base URL

All API requests go to:

https://api.quolle.com

Authentication

Pass your API key in the Authorization header as a Bearer token. API keys start with qle_ and are created in the dashboard under API Keys.

Authorization: Bearer qle_your_api_key
Keep your API key secret. It is shown only once when created. If you lose it, delete the key and create a new one.

Rate limits

Every API key is limited to 100 requests per minute. Exceeding this limit returns a 429 Too Many Requests response. The following headers are included on every authenticated response:

HeaderDescription
X-RateLimit-LimitMaximum requests per window (100)
X-RateLimit-RemainingRequests left in current window
X-RateLimit-ResetUnix timestamp (seconds) when the window resets

Response format

All responses are JSON. Successful responses return the resource or a confirmation object. Errors use the following shape:

{
  "error": "Human-readable error message"
}
