What is Quolle?
Quolle is a transactional email API and SMTP relay. You send an email — a password reset, order confirmation, or welcome message — and Quolle delivers it reliably via Amazon SES, handles bounces and complaints automatically, and gives you real-time visibility through webhooks and the dashboard.
Quolle is built specifically for Nigerian and African SaaS: pricing in Naira, no USD card required, and compliance aligned with the Nigeria Data Protection Commission (NDPC).
Core capabilities
- REST API — send a single email or a batch of up to 100 with one POST request. Supports raw HTML, saved templates, scheduling, and idempotent sends.
-
SMTP relay — plug
smtp.quolle.com:587into any framework (Laravel, Django, Nodemailer, Rails, WordPress) as a drop-in replacement for SendGrid, Mailgun, or any other SMTP provider. -
Email templates — create reusable Handlebars templates in the
dashboard and send them from your API key using the
templatefield — no JWT required. - Webhooks — subscribe to seven delivery events (sent, delivered, bounced, complained, failed, opened, clicked) with HMAC-signed payloads.
- Domain verification — add SPF, DKIM, and DMARC with guided DNS setup or one-click Cloudflare integration.
- Suppression list — permanent bounces and spam complaints are automatically suppressed to protect your sender reputation.
How to integrate
There are two integration paths. Both use the same API key and the same verified sending domain:
| Path | Best for | Guide |
|---|---|---|
| REST API | Custom code, any language with HTTP support | Quickstart · Send API |
| SMTP | Existing apps and frameworks with built-in SMTP config | SMTP Setup |
