Upsender: A Fully Custom ESP
Email marketing in the affiliate space isn't what it used to be. Gmail and Yahoo have cracked down hard on deliverability, and the tactics that worked a few years ago just don't hit the same anymore. That's not speculation. It's reality.
Upsender saw this coming and made a bold move: they built their own ESP from the ground up.
Full Control When It Matters Most
Most email service providers operate as third-party platforms with their own limitations, restrictions, and black-box algorithms. Upsender took a different approach. Their internal system combines email and SMS marketing in one place, giving their team complete control over deliverability, data, and performance.
What does that mean for ShipOffers clients? It means smarter, faster, and more personalized campaigns without the friction that comes from working around platform limitations. When you own the infrastructure, you can fine-tune every detail to drive better results.
A Strategic Shift That Makes Sense
Here's something worth paying attention to: Upsender has shifted their focus toward helping companies grow through their own internal products and promotions. When you own the offer and the list, you control the message, the margins, and the long-term results.
That doesn't mean they've abandoned affiliate emails. They still send plenty of those. But the priority has shifted toward strategies that put more control in the hands of their clients.
Growing Team, Steady Leadership
The Upsender team has grown to 14 full-time people, and founders Ryan and Justin recently hit their 4-year mark with the company. That kind of stability matters when you're trusting a partner with your email revenue.
What's Ahead
2026 is shaping up to be the year things start to normalize for email marketing. The recent changes have been challenging for everyone, but teams like Upsender that invested in building their own infrastructure are positioned to come out ahead.
For ShipOffers clients looking to maximize the revenue potential of every customer on their list, having a partner who controls their own deliverability stack is a serious advantage.
