Proof over promises

Campaigns can’t break your OTPs — separate streams, separate reputations Multi-region failover on every plan, including free 3,000 free emails/month — test every claim before you pay a kobo

Everything the imported tools forgot

💜

Naira Pricing

Pay in Naira. No FX risk, no dollar surprises. ₦0 to start.

⚡

API + SMTP

REST API or SMTP. Works with Laravel, Django, WordPress, Bubble, FlutterFlow.

📶

Offline Resilience

Queue emails when connectivity drops. Retry intelligently on reconnect. No lost OTPs.

📱

USSD Triggers

Native USSD support. Fire OTP alerts and transaction receipts straight from *737# flows with one endpoint.

🔒

NDPC-Aligned

Designed around Nigerian Data Protection requirements — with the documentation to support your own compliance.

📣

Campaigns, Separately Billed

Newsletters and announcements to your contact lists — priced by audience size, not volume, and billed apart from your API plan. Your transactional price never rises to cover a feature you might not use, and campaigns send on their own reputation, so a bad newsletter can never pause your OTPs.

🏷

Topics & Preferences

Let readers pick which emails they want. “Too many emails” costs you one category instead of the whole contact — with a hosted preference centre and one-click unsubscribe that scopes itself to the right topic.

📊

Delivery Analytics

Real-time open, click, bounce tracking in your dashboard.

🧺

Structured Receipts

Send order and shipping confirmations with schema.org markup — rich order cards in Gmail, and a clean branded fallback everywhere else. One request, both built for you.

📥

Inbound Email

Receive replies and support mail parsed into clean JSON and delivered to your webhook, signed. Build reply handling and email-to-action flows with no mail server to run.

Why Quolle exists

Every fintech in Lagos knows the moment: a user stuck at a USSD prompt, waiting for an OTP that went to spam — or never sent at all, because the email provider assumed the network never drops.

We built Quolle because the tools we imported weren't built for the conditions we ship in. Queues that hold your email through an outage and deliver the moment connectivity returns. A USSD endpoint, because *737# is a front door here, not an edge case. Naira billing through Paystack, because your infrastructure bill shouldn't fail on an FX card decline. Multi-region failover, because one region's bad day shouldn't be your users' locked-out day.

How it works

1

Add your domain — 2 minutes

Verify with DKIM, SPF, DMARC. Cloudflare users get one-click setup.

2

Get your API key — 30 seconds

Create a key in your dashboard. Starts with qle_

3

Send your first email — 2 minutes

Call the API or configure SMTP. SPF, DKIM and DMARC are set up for you — and the deliverability guide gets you to the inbox.

Simple, transparent pricing

In Naira. Always. Pay for the emails you send — campaigns are priced separately, so you only pay for them if you use them.
