SparkPost became Bird. ITPison stayed an email company.
Bird is now an omnichannel suite where email is one channel among many. ITPison is a dedicated email infrastructure platform — that is the entire product, not a feature tier
(Account setup begins with a short consultation.)
Dedicated IP infrastructure, isolated by default — not shared with an omnichannel platform’s other senders
Owned MTA source code — routing, retry, and failover logic you control, not a relay stack Bird may or may not maintain
Drop-Folder integration — connect any system without API development, SDK requirements, or engineering overhead

An email company vs. an omnichannel suite
Built for the moments when everything depends on one send.
When campaigns fail, they fail suddenly.
SparkPost / Bird
Bird’s product roadmap now serves email, SMS, WhatsApp, and payments across a unified customer engagement platform.
Email delivery remains a strong component — but it shares organizational focus, engineering resources, and support infrastructure with other channels.
Buyers who chose SparkPost for its concentrated email-infrastructure focus are now evaluating a different product than the one they originally selected.
ITPison
ITPison has one scope: enterprise email delivery via OMICard™ and the March™ MTA. No SMS, no payments, no omnichannel pivot — and no roadmap drift. For infrastructure buyers, that stability is a structural commitment, not a positioning claim.
ITPison is also built for white-label and multi-tenant operators. Per-tenant IP isolation and branded delivery are architectural defaults — not features retrofitted onto a platform serving other channels.
2002
ITPison core technology enters production (Omicard)
2009
ITPison formally founded as dedicated email infrastructure
>2011
SparkPost founded as email delivery platform
>2021
MessageBird acquires SparkPost for $600M. Omnichannel pivot begins.
2023
SparkPost rebranded as Bird Email. Email becomes one channel.
ITPison doesn’t need to position against what Bird has become. The acquisition history is the argument. ITPison occupies the category Bird abandoned: a focused, infrastructure-grade email platform with no competing priorities.
Shared Relay vs. Dedicated Infrastructure
SparkPost / Bird Routes
SparkPost / Bird routes traffic through shared cloud infrastructure with an API relay model. Dedicated IPs are available as an add-on, but the underlying sending stack remains a dependency on infrastructure Bird controls — and may reprioritize.
ITPison — March MTA
ITPison’s architecture is built around the March™ MTA — a relay-only engine running on fully owned source code. Routing logic, retry behavior, and failover decisions are controlled at the infrastructure level. Nothing in the critical sending path depends on a third-party stack.
With ITPison you get:
March™ MTA
Proprietary relay-only engine. Fully owned source code. Routing, retry, and failover behavior are controlled at the infrastructure layer — not inherited from a shared relay.
Traffic isolation by default
Transactional and campaign traffic run on separate infrastructure. One sender’s behavior cannot affect another’s reputation. Isolation is architectural, not configurational.
No omnichannel dependency
ITPison’s infrastructure is not shared with SMS, WhatsApp, or payments workloads. Email delivery is the only job this infrastructure performs.
API-only vs. the full integration spectrum
SparkPost / Bird
SparkPost / Bird
Bird’s entire model is API-first. That is not a positioning choice — it is a structural constraint. It works well for teams with dedicated engineering resources. For enterprise environments with compartmentalized IT, security review processes, or legacy systems, this creates a deployment timeline measured in sprints, not days
ITPison
ITPison — Drop-Folder
ITPison’s Drop-Folder Integration requires no SDK, no API development, and no custom integration code. Your system writes the recipient list, email content, and send configuration to a monitored directory. ITPison’s infrastructure retrieves the files and handles the rest. Every computer system can write files to a folder — which means any team, in any environment, can send through dedicated email infrastructure without a single line of integration code.
In large enterprises, connecting an external system via API often requires security reviews, multi-layer approvals, and engineering cycles that can take months. Drop-Folder bypasses that process entirely — because writing a file to a directory requires no special technical permissions to build.
Bird cannot offer Drop-Folder without rebuilding their integration architecture. ITPison offers Drop-Folder, API, and SMTP — the full integration spectrum. Whichever path fits your environment, ITPison supports it.
Support that’s included vs. support that’s an upsell
SparkPost / Bird’s ISP relations, deliverability mediation, and data analysis are gated behind a premium add-on plan. Message event history is limited to 10 days — anything beyond that requires configuring webhooks and storing data yourself.
For enterprise IT and ops teams running incident response or compliance workflows, this creates operational gaps that shouldn’t exist at any price tier.
ITPison’s consultation-led provisioning means delivery setup is scoped before your first email goes out — not after problems emerge. Delivery visibility is built into the platform. Sending logs, status, and performance tracking are accessible without additional cloud services, webhook pipelines, or support tier upgrades.

Moving from SparkPost / Bird to ITPison
1
Consultation & Assessment
Your current sending configuration, volume, and integration requirements are reviewed before any infrastructure is set up. Configuration decisions are made with your team, not unilaterally.
>2
Infrastructure Provisioning
Dedicated sending infrastructure, IP pools, and your chosen integration method — Drop-Folder, API, or SMTP — are configured to your specifications before go-live.
>3
Parallel Testing & Cutover
Testing typically occurs in parallel with existing SparkPost / Bird traffic. Cutover is coordinated after delivery performance is confirmed against your requirements.
FAQ
Can I keep using API or SMTP if I switch from SparkPost / Bird to ITPison?
Yes. ITPison supports SMTP and REST API integration, so existing application code routing through SparkPost / Bird can typically be reconfigured with minimal changes. ITPison also offers Drop-Folder Integration — an exclusive method that requires no API development or integration code. Your system writes the recipient list and email content to a shared directory; ITPison handles everything from there. No SDK, no approval cycles, no engineering project.
What does “dedicated infrastructure” mean compared to SparkPost / Bird’s shared model?
SparkPost / Bird routes traffic through shared infrastructure by default. Dedicated IPs are available but positioned as an add-on. ITPison’s infrastructure isolates your sending environment from other senders by default — your IP reputation reflects your own sending behavior, not a shared pool’s aggregate.
Critically, ITPison also separates transactional and campaign traffic at the infrastructure level. One sender’s behavior, or one traffic type’s behavior, cannot affect another’s reputation. For high-volume senders and platform operators managing multiple customers, this isolation is a core operational requirement, not an optional upgrade.
Is there a self-serve signup?
No. All accounts are provisioned after an initial consultation. Infrastructure configuration — authentication setup, IP assignment, integration method, routing structure — directly affects long-term deliverability. Getting it right before the first email goes out is the point of the consultation process. This also means no billing surprises mid-cycle and no account suspensions from configuration issues that weren’t caught at setup.
