How do you write a partnership proposal email?

Open with why you are writing to this company in particular, such as a shared customer or a problem both of your customers have. Say in one or two sentences what the partnership would give their clients and them. End with one easy question, such as a 20-minute call next week. Keep the whole email under 120 words.

What is a good subject line for a partnership email?

Use something specific to them, not a generic phrase like partnership opportunity. A shared customer's name, their product next to yours, or a direct question works well. Keep it under about eight words so it shows in full on a phone, and avoid anything that reads like a marketing campaign.

How many times should you follow up on a partnership email?

Two follow-ups after the first email is usually enough: one after four or five days with something new to say, and a final one two to three weeks after the first email that closes the loop politely. A warm introduction from a shared customer between those two often works better than a third email.

Should I mention the commission in my first partnership email?

Mention that there is one, briefly, but do not lead with it. The first email should be about their clients and why you are a good fit for them. Partners who reply mainly because of the fee tend to send weaker referrals. Give the full terms on the call and in the recap.

What should I send a partner after they are approved?

A short welcome email with one clear next step, usually booking a kickoff call, plus a link to sign the agreement and add their tax form. Avoid sending a long list of resources on day one. Share training and materials on the kickoff call, when the partner knows which clients they will introduce first.

In short

A good partnership email is short, specific to the recipient and ends with one easy question. This pack gives you 10 ready-to-send emails with subject lines: first outreach to an agency, a technology partner and a customer, two follow-ups, a call recap, a welcome email, a first-referral nudge, a quarterly check-in and a re-engagement email.

What this template covers

These are ten short emails for the whole life of a partnership, from the first cold message to winning back a partner who has gone quiet. They are written for B2B SaaS companies recruiting agencies, consultants, technology partners and customers who refer.

The emails follow the order you will need them:

First outreach to an agency or consultancy, built around a shared customer.
First outreach to a technology or integration partner, built around shared users.
Asking a customer to refer you, best sent after a renewal or good feedback.
A follow-up four or five days after no reply, with something new to say.
A final follow-up that closes the loop politely.
A recap after the intro call, with terms and one next step.
A welcome email after approval, asking for one action: booking the kickoff call.
A first-referral nudge for partners who have not sent anything by day 30.
A quarterly check-in with the partner's numbers and a request for a review.
A re-engagement email for a partner who has been inactive for months.

Each email has a one-line note on when to use it, a subject line, and placeholders in brackets for names, numbers and links.

How to use these emails

Fill in every bracket before you send. The placeholders that matter most are the specific ones: the shared customer, the problem their clients have, the three target clients named on the kickoff call. An email with those filled in reads as written for the recipient. One without them reads as a template, because it is.

Put the outreach emails into a sequence. Emails 1, 4 and 5 make a three-touch sequence over about three weeks. Add a LinkedIn message or a warm introduction from a shared customer between the follow-ups. The how to recruit partners guide covers the sequence, the call and how to qualify candidates before you write to them.

Use the onboarding emails at fixed points. Emails 7 and 8 match steps in the partner onboarding checklist: the welcome email on approval day and the first-referral nudge around day 21 to 30. Sending them at the same point for every partner is what makes onboarding consistent.

Send the recap the same day. Email 6 is where the partnership gets written down. State the terms in plain words, and link to your agreement. The referral partner agreement template covers what the terms should include.

What makes a partnership email work

Short. Under 120 words for a first email. Busy agency owners read the first three lines on their phone and decide.
About them. Their clients, their product, the customers you share. Your product comes second.
One ask. A single question or next step per email. Two asks usually get neither.
Plain subject lines. A shared customer's name or the two product names together beats any clever phrase.
Human tone. Write the way you would to someone you have met once. Avoid stock phrases like "mutually beneficial" and anything that sounds like a press release.
Honest about money. Say there is a fee or margin, but give the numbers on the call and in the recap, not in the first line.

After they reply

A reply is the start of a recruiting conversation, not the end. Book the call within a week while interest is high, and use the call to qualify them as much as to pitch. Ask about their clients, who they work with at each one, and why they want to partner.

If the partner signs, move straight into onboarding: approval, the agreement and tax form, portal access and a kickoff call in the first week. If they do not, note why and when to check back. Partners who said "not now" are often the easiest to sign six months later, especially when you can name a shared customer who has joined since.

Partnership Email Templates

Ten short emails for recruiting partners and keeping them active, from the first outreach to re-engaging a partner who has gone quiet. Replace everything in brackets before you send. Keep the emails short: the shorter the first email, the more likely a busy agency owner reads to the end.

Each email has a one-line note on when to use it, a subject line and the body. Swap in your own voice, but keep one question or one next step per email.

1. First outreach to an agency or consultancy

5. Final follow-up

When to use: 2 to 3 weeks after the first email, as the last message in the sequence.

Subject: Should I close the loop?

Subject: Still a fit for your clients?

Hi [First name],

Is working together still useful for [Their company]? If now isn't the time, just say so and I'll check back in [number] months. If it is, I'd be glad to set up a quick call to pick a couple of clients to start with.
