Interspire builds email marketing software for organizations that want to own their infrastructure, not rent it.
Founded in 2003, Interspire has spent more than two decades building professional-grade email marketing software used by digital marketers, publishers, agencies, and email service providers worldwide. From the beginning, the mission was clear: give businesses direct control over how they communicate with their audience, without forcing them into recurring service fees.
“I am a long time user of Interspire Email Marketer, Recently we upgraded to the newest version of the program. We had a few issues on our end and […] Interspire took the time and effort to help us get set up and make it possible to create beautiful emails. The program works without limitations and I would recommend this program to all, big or small! Thanks […], Great Job!!”

Built for ownership, not dependency
Interspire Email Marketer is a fully self-hosted, downloadable email marketing automation platform. Unlike SaaS products that lock you into monthly subscriptions and external systems, Interspire runs on your own infrastructure, under your rules.
Your data stays with you.
Your sending strategy stays with you.
Your costs stay predictable.
This approach is not accidental. It is a deliberate alternative for teams that prefer long-term control over convenience-driven platforms that dictate pricing, limits, and access.
Interspire is not for everyone. It is for organizations that want flexibility, customization, and full independence.
A focused product with a clear direction
Interspire was founded in Sydney, Australia by Eddie Machalaani and Mitchell Harper. The founders later launched BigCommerce in 2009. After the two companies separated in 2018, Interspire continued its focus on self-hosted email marketing.
In 2021, Interspire was acquired by a small technical team with a single mandate: continue evolving Interspire Email Marketer as a serious self-hosted alternative to SaaS email platforms. Development today prioritizes performance, stability, modernization, and long-term maintainability, not growth at any cost.
Trusted by teams who take email seriously
For over 20 years, Interspire has helped thousands of organizations take control of their email marketing. Customers use Interspire to attract new subscribers, build lasting customer relationships, and manage large-scale email communications on their own terms.
If you are looking for a quick setup with minimal responsibility, Interspire is probably not the right fit. If you are looking for a platform you can own, adapt, and rely on without ongoing subscription fees, Interspire was built for you.
