Enterprise-grade infrastructure. No engineering team required.
Mailgun is a powerful email API built for developers. If you have an engineering team, it works. If you don’t — or if your systems can’t consume an API — dedicated infrastructure has been out of reach. Until now.
(Account setup begins with a short consultation.)
Drop-Folder integration removes the API requirement — any system, any team, no engineering overhead
Dedicated IP infrastructure included from day one — not an add-on you unlock at a higher tier
Supported from setup to scale — provisioned before your first send, not after your first problem

The API requirement is the barrier
Mailgun’s developer-first model is genuinely strong for teams with engineering resources. The API is well-documented, the libraries are comprehensive, and integration is fast — if you have someone to write the code. For teams that don’t, or for enterprise environments where API development requires security reviews and multi-layer approvals, the integration path doesn’t exist.
Mailgun
Mailgun provides SMTP and REST API integration. Both require an engineer to build and maintain the connection. There is no integration path for non-developers.
For startups without dedicated engineering resources, or for enterprise teams where external API connections require a formal approval process, Mailgun’s infrastructure is effectively inaccessible regardless of how well-priced the plan is.
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 on a server.
ITPison’s infrastructure retrieves the files and processes the delivery. Every computer system can write files to a folder — which means any team, in any technical environment, can access dedicated email infrastructure from day one.
The difference isn’t just convenience. It’s access. For teams without engineering resources, Drop-Folder is the only path to dedicated infrastructure that doesn’t require hiring someone first.
Mailgun (what’s required):
1. Engineer builds API connection
2. Security review (enterprise)
3. Ongoing maintenance
4. Email sends via Mailgun relay
ITPison Drop-Folder (what’s required):
1. Any system writes files to folder
2. ITPison retrieves & processes
3. Email delivers via dedicated infrastructure
Mailgun cannot offer a no-code integration path without rebuilding its architecture. ITPison offers Drop-Folder, SMTP, and API — the full integration spectrum. The path that fits your team is available from day one.
Dedicated infrastructure shouldn’t be a tier upgrade
Mailgun’s developer-first model is genuinely strong for teams with engineering resources. The API is well-documented, the libraries are comprehensive, and integration is fast — if you have someone to write the code. For teams that don’t, or for enterprise environments where API development requires security reviews and multi-layer approvals, the integration path doesn’t exist.
Dedicated IPs on Mailgun cost $59/IP/month extra and aren't standard until the Scale tier ($90/mo+). Deliverability optimization is a separate add-on from $49/month.
Message log retention starts at 5 days on Foundation — insufficient for incident response or compliance. ITPison scopes dedicated infrastructure, IP isolation, and delivery configuration before go-live — not as upsells after problems emerge.
For agencies and platform operators, there's an additional gap. Mailgun's sub-accounts create separate sending identities within a shared environment — not isolated infrastructure.
One client's poor sending behavior can affect others on the same account. ITPison isolates each tenant at the infrastructure level: separate IP pools, separate reputation signals. Architectural, not configurational.
What “dedicated infrastructure” actually costs on Mailgun: Foundation plan ($35/mo) + dedicated IP ($59/IP/mo) + Optimize deliverability add-on ($49/mo) = $143/mo before you’ve sent a single email with the infrastructure controls that should come standard. On ITPison, these aren’t line items — they’re part of the provisioning conversation
March™ MTA
Proprietary relay-only engine. Fully owned source code. Routing, retry, and failover logic controlled at the infrastructure level — not dependent on a shared relay stack.
IP isolation by default
Dedicated sending environments designed to prevent cross-client reputation bleed. Your sending behavior is the only variable in your IP’s reputation.
No cloud lock-in
ITPison operates independently of any cloud provider’s infrastructure. Your email stack isn’t tied to Sinch’s platform decisions or pricing changes.
Knowing what happens after send
Mailgun’s Foundation plan retains message logs for 5 days. Scale tier extends this to 30 days. For enterprise teams running compliance workflows, incident response, or delivery audits, 5 days is operationally insufficient — and even 30 days requires being on a higher-cost plan to get there.
Mailgun’s Optimize add-on — covering inbox placement testing, deliverability data analysis, and ISP insights — starts at $49/month on top of your base plan. This is the base product, acknowledging it doesn’t include the tools needed to maintain delivery health, then charging separately for them.
ITPison’s delivery observability is built into the platform. For enterprise environments where IT and ops teams — not just developers — need visibility into what’s happening after send, the distinction matters.

Who each platform is built for
Mailgun is a genuinely strong product — for the buyer it was designed for. The question is whether that buyer is you.
Mailgun
Mailgun may be the right choice if:
• Your team has engineering resources to build and maintain API integrations
• You need inbound email processing, which Mailgun handles well
• Strong API documentation, SOC2/HIPAA compliance, and developer tooling are priorities
• You’re optimizing for per-email cost at high volume and have already built on Mailgun’s API
Mailgun may not be the right fit if:
• You need to integrate without an engineering project or API development cycle
• Dedicated IPs and deliverability support being add-ons is a cost or risk concern
• Your ops or IT team — not just developers — needs delivery visibility and access
Choose Mailgun if: You have engineering resources and need a developer-first API with inbound processing
ITPison
ITPison may be the right choice if:
• You need white-label or multi-tenant infrastructure with per-tenant IP isolation — Mailgun's sub-accounts are a configuration layer, not isolated infrastructure
• You want dedicated infrastructure without an engineering team or API development overhead
• IP reputation and delivery reliability are operationally critical from day one
• You need a white-label or multi-tenant sending platform for your customers
• Your systems include enterprise workflows, batch processes, or environments that can’t easily consume an API
ITPison may not be the right fit if:
• Self-serve, immediate provisioning is a hard requirement
• You need inbound email processing — Mailgun handles this; ITPison does not
• You’re optimizing for the lowest possible per-email cost above infrastructure control
Choose ITPison if: You need dedicated infrastructure and integration that doesn’t require an engineering team
Moving from Mailgun 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 Mailgun traffic. Cutover is coordinated after delivery performance is confirmed against your requirements.
>FAQ
Can I keep using SMTP or API if I switch from Mailgun to ITPison?
Yes. ITPison supports both SMTP and REST API integration, so existing application code routing through Mailgun 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 required.
What does “dedicated infrastructure” mean, and how is it different from Mailgun’s dedicated IP add-on?
Mailgun’s dedicated IP is an additional IP address added to an otherwise shared sending environment, available as a paid add-on from $59/month per IP.
ITPison’s dedicated infrastructure means your sending environment is isolated from other senders by default — your IP reputation reflects your own sending behavior, not a shared pool’s aggregate. Routing, retry, and failover logic run on March™, ITPison’s proprietary MTA with fully owned source code. This is an architectural difference, not a configuration option.
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 the setup serves your actual sending environment, not a default configuration built for a generic use case.
