10 Partnership Email Templates for B2B Collaboration

Hi {First Name},

Loved your recent piece on {specific topic}. We serve a very similar audience at {Your Company} — {short value prop} — and I think a co-produced {webinar / ebook / template} on {angle} would be gold for both our lists.

Rough shape:
• You bring the expertise on {their strength}
• We handle production, promotion to our {N}k list, and design
• Both teams get co-branded assets + shared leads

Open to a 15-min call next week to explore?

Hey {First Name},

Your audience of {audience description} is exactly who we help at {Your Company} with {one-line problem/solution}.

We just opened an affiliate program with:
• 30% recurring commission (lifetime)
• 90-day cookie
• Ready-to-post assets, demo videos & landing pages
• Dashboard with real-time earnings

Given your reach, this could add {rough dollar figure}/mo in passive income without changing what you already do.

Want the affiliate signup link and a 5-min walkthrough?

Hi {First Name},

I run {Your Company} — we do {your specialty}, which is a natural add-on to the {their service} work you do at {Their Agency}.

Idea: a mutual referral pact. When your clients ask about {your service}, you send them to us for a {X}% referral fee. We do the same when ours ask about {their service}.

No contracts, no lock-in — just a shared Slack channel and clean handoffs. We already do this with 4 other agencies and it adds ~$8k/mo in warm work with zero acquisition cost.

Worth a quick call?

Hi {First Name},

We hear "{Your Product} + {Their Product}" from customers weekly. About {N}% of our users already use {Their Product}, and I'm sure the reverse is true.

I'd love to build a native integration:
• {Specific use case #1}
• {Specific use case #2}
• Joint launch post + co-marketing to both lists

Our dev team can ship a v1 in ~2 weeks. All we'd need from your side is API docs access + one product review pass.

Interested? I can send a 1-page spec.

Hi {First Name},

Long-time reader — your piece on {specific post} is what got me thinking about pitching this.

I'd love to write a data-backed guide for {Their Blog} on:

"{Specific working title}"

I'd bring:
• Original data from {N,000} {your niche} we analyzed
• 3 case studies with named customers
• Custom charts and a downloadable template

I've written for {publication 1}, {publication 2}, and my own audience of {N}k. All I ask in return is a byline and one contextual link to a related resource on our site.

Want the full outline?

Hey {First Name},

Been binging {Their Podcast} — the episode with {previous guest} on {topic} was excellent.

I'd love to come on and talk about {specific angle you can uniquely cover}:
• {Concrete story / stat #1}
• {Concrete story / stat #2}
• A framework your listeners can steal that day

Background: I'm {credentials in one line}. I've been on {podcast 1} and {podcast 2}, so I know how to be a good guest.

If it's a fit, I'll come prepared with clips, a topic outline, and I'll promote the episode to my {N}k audience the day it drops.

Hi {First Name},

{Their Company} is one of the strongest names in {region / vertical}, and {Your Product} has real demand there we can't serve well from where we sit.

I'd like to propose a reseller partnership:
• Discounted licensing (starting at 30% off)
• Co-branded materials + localized landing pages
• Dedicated partner manager on our side
• Deal registration to protect your pipeline

We're piloting this with {N} partners already averaging {$X}k MRR per partner within 6 months.

Would love to walk you through the model — 20 minutes next week?

Hi {First Name},

Just saw your account hit {milestone — MRR, sends, leads, etc.}. Genuine congrats — that's real work.

Would you be open to being featured in a {case study / video testimonial / joint webinar}? Here's what you'd get:

• Full case study written and designed by our team (yours to reuse anywhere)
• Distribution to our {N}k audience — great for your brand + hiring
• Featured slot on our homepage and product pages
• A free 12-month upgrade to {higher plan} as a thank-you

30 minutes on Zoom is all we'd need to record the story.

Interested?

Hi {First Name},

I run {Your Newsletter} — {N}k subscribers, {open rate}% open rate, focused on {topic}. Your audience at {Their Newsletter} is a near-perfect overlap.

Simple ask: a mutual featured slot.

• I dedicate one section of an upcoming issue to {Their Newsletter} (~60-word blurb + link)
• You do the same for us in an issue of your choice, same week

No money changes hands. Everyone wins subscribers who are already primed for this content.

Want to pick a date? Happy to draft copy for both sides.

Hi {First Name},

Bumping this in case it got buried — completely understand if the timing's off.

Quick recap: {one-sentence recap of the original pitch}.

If it's not a fit for {Their Company} right now, no worries at all — is there someone else on your team I should route this to, or should I circle back in Q{next quarter}?
