Co-Marketing Proposal
Proposing content partnerships with complementary companies to reach shared audiences. Works best with companies that sell to the same persona but don't compete directly.
The template
Subject: Co-marketing idea: {{your_company}} + {{their_company}}
Hi {{first_name}},
I've been following {{their_company}} and I think there's a genuine audience overlap between us — {{why_your_audiences_align}}.
We're planning {{specific_content_or_campaign}} and thought a joint piece could be valuable for both audiences.
Specifically, I'm thinking {{concrete_collaboration_idea}}. We could each promote it to our respective audiences ({{your_audience_size}} on our side).
