The platform
Built for delivery, not just sending
Carrier routes, receipts, retries, and regulatory filings — the unglamorous parts of messaging, handled.
Direct carrier connections
450+ direct routes into 195 countries — messages take the short path, not the grey route.
Two-way messaging
Inbound replies stream to your webhook in real time for surveys, support, and confirmations.
Real-time delivery reports
Per-message delivery receipts with failure reasons, and automatic retries up to three times.
Message scheduling
Queue campaigns up to six months ahead, in any timezone, from the dashboard or API.
Sender ID management
We file registrations with the regulator in each market and keep them current.
Compliance built in
GDPR-aligned, built for Kenya's DPA and Nigeria's NDPR, with automatic DND filtering for promos.
REST API & 7 SDKs
PHP, Python, Node.js, Java, C#, Go, and Ruby — most teams send their first message within the hour.
Campaign tools
Contact groups, templates, and per-recipient personalization without writing code.
99.95% uptime
Redundant delivery infrastructure across data centres, with automatic failover.
Regions
Lagos is home. Nairobi and Dar es Salaam are one API call away.
Deploy in ng-1a and the machine sits in Lagos, in the same city as most of the traffic it will ever serve. Nigeria makes that easy to reason about: 189.68 million active mobile subscriptions in May 2026, with MTN and Airtel together carrying about 86% of active lines and Globacom and T2 — the operator formerly branded 9mobile — behind them. Whichever of the four your customer is on, they are in Nigeria, and typical in-metro round trips here run around 4 ms.
Nigerian networks now hand traffic to each other in Nigeria. IXPN, the neutral national exchange founded in 2006 by the NCC, runs 13 points of presence across 7 states and more than 130 connected networks, with 400G-capable core switching at three Lagos sites; peak domestic traffic across it passed 1 Tbps in April 2025 and 2 Tbps by March 2026. Before it existed, two Nigerian networks exchanged packets by way of London — an intercontinental journey for a packet crossing one city.
Eight subsea systems come ashore in the country, Equiano landing on the Lagos coast in 2022 and 2Africa at Lekki, which is how Lagos became West Africa's arrival point for international capacity. Aim a request at Frankfurt or Virginia instead and that subsea path joins the critical route of every call the page makes, at typically around 110 to 125 ms before your application does any work. From Lagos, Accra and Nairobi typically sit further away in round-trip terms than London, because traffic between African networks still frequently transits Europe.
ke-1a in Nairobi and tz-1a in Dar es Salaam run on the same account and the same API, which makes a standby or a disaster-recovery plan a configuration rather than a second supplier. Make that call deliberately where personal data is involved: a copy of Nigerian personal data held abroad is a cross-border transfer under section 41 of the NDPA. Machine images and telemetry raise no such question.

Support
West Africa Time, and a ticket that arrives with the facts
Two channels, doing different jobs. A ticket opened while signed in arrives carrying your account, your region and the instance, so the first reply is about the problem rather than about which machine you mean. [email protected] is the commercial address: a quotation against a purchase order, transfer details before a payment run, the billing account configured with your TIN and registered name before the first invoice, and the SLA terms and credit-claim process in writing while you are still choosing.
Before either, status.lineserve.net. Anything affecting a whole region is posted there faster than a reply could reach you, and checking it turns "my site is down" into "my instance is unreachable and the status page is clear" — a different ticket, and a much shorter one.
What to put in it, in the order it gets read: the region and the instance, the time the behaviour started in WAT, what changed just before it, the actual error text rather than a description of it, and whether it reproduces from more than one Nigerian network. An MTN handset and an office fibre line disagreeing is a different fault from both failing together.
Some of the fastest resolutions need nobody at all, and are worth knowing before the night you need them. Restore an on-demand snapshot. Roll back to a scheduled backup. Open the browser console when SSH is the thing that has broken. Resize or rebuild from the API. Migration planning and assistance are included at no extra charge.
Nigeria runs on West Africa Time, UTC+1, and does not observe daylight saving — two hours behind Nairobi and Dar es Salaam. A change window agreed in WAT means the same thing in January and in July. Note the offset when you schedule across regions.

Why Lineserve
Local routes beat global relays
Global aggregators relay African traffic through whoever is cheapest this week. Direct carrier connections and local registrations are what actually move delivery rates.
FAQ
Questions, answered
Transactional messages — OTPs, confirmations, notifications — are exempt from Do-Not-Disturb registries and deliver around the clock. Promotional campaigns require opt-in and are automatically filtered against DND lists where they apply.
We file the paperwork with the regulator for you. In Kenya, Communications Authority approval typically takes 2–3 business days once your business documents are in; Nigeria and Tanzania follow their own regulators with similar handling.
