About Us
We care deeply about email performance — because we’ve lived the frustration of missing important messages.
Sending Partners was born after some of our favorite brands started landing in our spam folders. We reached out to help — and quickly realized that nearly no one was looking under the email content: at the infrastructure, the data quality, or the hidden factors that impact reach.
What we found was a massive blind spot in email strategy. So we built the world’s first agency dedicated entirely to solving it.
Sending Partners is an Email Performance Optimization agency
We believe your emails should get seen, not silently filtered. And we believe email should drive measurable results, not just sit in a dashboard.
So we created a new kind of partner: one that focuses exclusively on the backend of email — from technical deliverability to list hygiene, behavioral signals, and performance analytics.
That mindset is present in everything we do:
Engineers who fix systems most marketers never look at
Strategists who make sense of deliverability data and tie it to revenue
Operators who build scalable, high-signal programs behind the scenes
We don’t write your emails. We make sure they land.
And we don’t believe in best practices for the sake of it. We believe in real performance — and we test, measure, and validate everything against that goal.
Sending Partners was founded after helping a handful of brands recover from invisible performance loss — poor inbox placement, decaying list health, and false signals that made email look “fine” in tools, but fail in real inboxes.
Since then, we’ve helped B2B lead-gen firms, ecommerce brands, and email-first SaaS businesses fix their sending stacks, optimize for revenue, and regain trust with inbox providers.
Our early growth has been driven entirely by word of mouth and client results. Because when you double someone’s email reach, people notice.
Want to work with us?
We work with high-performing teams that rely on email to drive results — and can’t afford to lose 30–50% of their reach to silent filtering.
If you suspect a hidden deliverability problem, or if your email results have plateaued, let’s talk.
