You've identified a company you'd love to partner with. Maybe it's a complementary product. Maybe it's a shared audience. Maybe there's a co-marketing opportunity that would benefit both sides.
Now you need to pitch it. Over email. To someone who probably gets a dozen partnership proposals a week.
Most of them are bad. Long, vague, and clearly more beneficial to the sender than the recipient. Here's how to write one that stands out.
Why Most Partnership Pitches Fail
They're one-sided. The email spends four paragraphs explaining what the sender gets and one sentence on what the recipient gets.
They're vague. "There are so many synergies between our companies!" Like what? Be specific.
They're too long. A partnership proposal email isn't a business plan. It's a conversation starter.
They skip the "why now." What's the trigger? Why should they consider this today and not file it under "maybe someday"?
The Partnership Email Framework
1. Connection point
Why are you reaching out to them specifically? What do you know about their business that makes this relevant?
2. The opportunity (for them)
Lead with what they get. Not what you get. Not what "we" get. What they get.
3. What it looks like
A concrete example of what the partnership could involve. Not "we could explore synergies," but "a co-branded webinar to our combined 15K email subscribers."
4. Proof it works
Have you done something similar before? What were the results?
5. Light ask
"Would this be worth a 15-minute conversation?" Not "Let me send you our 20-page partnership deck."
Proposing a co-marketing partnership to a complementary SaaS company
“Hi Mark, I'm the Head of Partnerships at DataFlow. I believe there's a huge opportunity for our two companies to work together. We have a lot of overlapping customers and I think a partnership could be really beneficial for both of us. We could do co-marketing, integrations, referrals, and more. Would love to set up a call to explore this further. Let me know when you're available for a 30-minute chat.”
“Hi Mark, noticed that a lot of DataFlow customers ask us about analytics tools, and we've been recommending Acme Analytics informally for a while. We have 8K active users in the mid-market B2B segment, which looks like your sweet spot. One idea: a joint webinar on 'turning product data into growth metrics,' promoted to both our lists. We ran a similar co-marketing campaign with Relay last quarter and it generated 340 signups, 12% of which converted. Worth exploring? Happy to start with a quick call or share more details over email, whatever's easier.”
The second email leads with what Mark gets (access to 8K mid-market users), proposes something concrete (a webinar), provides proof (340 signups from a similar campaign), and makes a small ask.
Making It About Them
The hardest part of a partnership pitch is genuinely thinking about it from the other side. Before you write, answer these questions:
- What does their company need right now?
- What do they get from working with us that they can't get alone?
- Why would their team spend time on this instead of other priorities?
- What's the minimum viable partnership that proves the concept?
If you can't answer these, you're not ready to send the email.
Types of Partnerships to Propose
Co-marketing: Joint webinars, content, events. Low commitment, easy to test.
Integration: Building a technical connection between products. Higher commitment, higher value.
Referral: Sending customers to each other. Requires trust and aligned audiences.
Bundling: Offering products together. Requires pricing alignment and significant trust.
Start with the lowest-commitment option. If it works, you can expand. Proposing an integration before you've even had a conversation feels presumptuous.
Common Mistakes
Proposing too much at once. "We could do co-marketing, integrations, referrals, reseller agreements, and joint events!" Pick one thing to start.
Not doing homework. If you don't know their customer base, their pricing model, or their recent announcements, you're not ready to propose a partnership.
Being too formal. Partnership proposals that read like legal documents don't get responses. Write like a person.
Following up too aggressively. One follow-up after a week. That's it for a cold partnership pitch.
Let ColdCheck Draft the Pitch
You know the opportunity. Articulating it clearly and concisely is the challenge.
"Partnership email to Mark at Acme Analytics. Our customers keep asking about analytics tools and we've been recommending them. We have 8K mid-market B2B users. Idea: joint webinar on product data and growth metrics. Did similar campaign with Relay, got 340 signups. Want to explore."

The Bottom Line
A good partnership proposal leads with what the other side gets, proposes something specific and testable, and proves the concept with past results. Keep it short. Start small. Make it easy to say yes.
The best partnerships start with one small successful collaboration, not a 20-page strategic plan.
