WhatsApp, SMS & email messaging API
Engispider Comms
One API for WhatsApp, SMS and email — with retries and receipts.
A multi-tenant communication service that centralises outbound WhatsApp, SMS and email. Applications post a channel, recipient and template code; the hub resolves the provider, sends, retries with exponential backoff, and records delivery receipts. Switching SMS providers becomes a config change rather than a code change.

Who it is for
Find yourself on this list.
Product teams that need transactional messaging without each application integrating Meta WhatsApp, an SMS gateway and SMTP separately.
We would rather tell you this is the wrong product than sell you a configuration that fights your process. Where nothing in the catalogue fits, we build the system instead.
Custom softwareGetting it running
Five phases, and you check each one.
How long it takes depends on how much history has to come across and how many sites are involved. You get a phase plan with dates before work starts.
Onboarding is free with the subscription.
Setup, data migration, training and go-live are not billed as a project and there is no joining fee. Support continues under the same subscription once you are live.
Configuration
Your branches, roles, tax rates, document formats and approval rules — set up against how you work now.
Free
Data migration
Existing records imported from Excel, CSV or a database export, validated, with an error report before anything commits.
Free
Training
Your team trained on the screens they will actually use, on your own data rather than a sample set.
Free
Go-live
Production cutover, with us on hand through the first days of real use.
Free
Support
A support agreement with response times and a named contact, covering fixes, updates and enhancements.
Free
Support hours are Mon–Fri 9:00–18:00 · Sat 9:00–14:00 IST — the same hours in the agreement as on this page.
Start with a scoping call
Before you ask
The six that come up every time.
Answered straight, with no figure we cannot stand behind. The rest are on the full FAQ.
Can I see the software before buying?
Yes. We run a guided demo on a live system with your own scenarios, rather than giving out a self-serve login — our products are multi-tenant deployments where each customer has their own isolated instance. Contact us and we will schedule a demo, usually within two working days.
Can you migrate data from the system we use now?
Yes. Data migration is part of every deployment. We import existing records — students, items, customers, stock, ledgers — from Excel, CSV or a direct database export, validate them, show you an error report before anything is committed, and reconcile the result against your current balances.
How long does a deployment take?
A product deployment typically runs in phases: configuration, data migration, training, then go-live. The length depends on how much historical data has to come across and how many sites are involved. We give a phase plan with dates in the scope document before work starts, and each phase ends with working software you can check.
How is the software priced?
Pricing depends on the product, the number of users or outlets, and whether you need custom work on top. We quote per project after a scoping conversation rather than publishing a rate card, because a single-outlet cafe and a twelve-college group need very different things. Contact us for a quote.
Is our data kept separate from other customers?
Yes. Our multi-tenant products scope every record to an organisation identifier taken from the authenticated session and enforced on the server for every query, so no request can read another tenant’s data. Where a customer requires it, we also deploy a dedicated instance.
What happens after go-live?
Support continues under an agreement that sets out response times and a named contact. That covers bug fixes, updates and enhancements. Our support hours are Monday to Friday 9:00–18:00 and Saturday 9:00–14:00 IST.
