Who We Are
The team behind Maileroo and CampaignLark, building email platforms from the ground up, driven by user feedback and a love for the craft.
The team behind it all
Think of us as a bunch of email enthusiasts who came together in 2022 to create Maileroo, an email delivery solution providing SMTP and Email API for software, websites, and applications.
We are Areeb and Patrick, and we first met in 2020 during our first year at university in Melbourne. With backgrounds in both front-end and back-end development, we built Maileroo with one goal in mind: to create better, more reliable email infrastructure for developers and businesses.
We focus on building an experience shaped by real user feedback. We love connecting with people from all backgrounds and see that as a strength in creating a platform designed purely for the happiness and success of our users.
From Maileroo to CampaignLark
In 2024, we at Maileroo released our email marketing platform and since then have spent time conducting feedback surveys, focus groups and 1:1 sessions to improve our systems. With our previous email marketing product being quite restrictive and providing only the necessities for sending, we took that feedback, pulled it out of the Maileroo ecosystem, rebranded it and isolated its infrastructure into this new and improved platform, CampaignLark.
Crafted with passion
We have people all over the world engaging and working within our team, but the core team is based in Australia, offering a support experience shaped by our email and development backgrounds. We take what we do seriously; it has become a big part of our lives, and we are proud of the systems Maileroo and CampaignLark are part of. We are committed to upholding our high standards of support and infrastructure reliability.
What we mentioned above isn't all talk - it's real
You can see our commitment reflected in our reviews, we recommend reading what others have shared on Trustpilot, G2, Capterra.
We are a founder-led team building and running our own infrastructure from the ground up. No wrappers, no reselling, just systems we design, deploy, and maintain ourselves to ensure performance and reliability. Since 2022, we have focused on strong engineering and genuine support. Thanks for getting to know us.
A Total Marketing Experience
We aim to expand from email into a multi-channel marketing space - all under one roof. The goal is not just to build individual tools, but to create an experience where every channel syncs with the others, drawing in rich data and turning it into information that enables better decisions.
Email Today. Marketing Tomorrow.
Driven by user feedback, we saw a real need behind a unified marketing experience. Drawing from major industries, we are truly creating an experience that individuals, agencies and businesses can engage and scale with.
Data Turned Into Information
Imagine a multi-channelled marketing experience where your data isn't just numbers and figures, but a story, insight and new depth into understanding your customers and their needs.
Uniform Productivity & Collaboration
Isolated marketing workspaces with shared data and tools, allowing for seamless collaboration and productivity. Collaboration between teams and clients will get a whole lot better.
One synced ecosystem
Every tool will connect with the others, drawing rich data from each source. The result is an ecosystem where data becomes information, so you can make more informed decisions instead of guessing.
Unified engagement & growth
Engage with your customers and track business growth in a uniform, simple way. You will be able to spot growth opportunities and roadblocks you were not aware of, all in one place.
Everything you need to know about setup, features, and running campaigns with confidence.
