How Mailin built a steady affiliate channel worth $45,201

Mailin is a B2B email platform run by a small team that would rather build product than operate marketing infrastructure. Not every affiliate program is a rocket, and this story deliberately isn't one — it is what the channel looks like for most SaaS companies that do it right: $45,201 in revenue generated from affiliates, compounding steadily since the program connected in December 2024, on close to zero operational effort.

The founding constraint was time. A channel a two-person marketing function can run has to attribute itself, price itself, and only ask for humans at the approval step.

Mailin connected its billing to Referly through the integration, which changes what an affiliate sale is: not a pixel firing on a thank-you page, but the actual subscription event. When a referred customer subscribes, the sale attributes to the referring partner and the commission computes against the plan — recurring revenue included. Nobody reconciles a marketing dashboard against Stripe at month-end, because the ledger is the billing truth.

The roster is deliberately modest — 85 active affiliates who generated 3,923 clicks — and the operating load matches: partners self-serve in the portal at mailin.referly.so, commissions queue themselves, and the team's recurring work is approving and paying. The founder's own review of Referly praises response times, but the deeper economics are simpler: the channel produces five figures and consumes almost none of the company's scarcest resource.

• $45,201 generated from affiliates — recurring B2B revenue, attributed at the billing layer.

• Self-serve roster — 85 partners managing their own links and details.

• Approve-and-pay operations — the whole recurring workload, measured in minutes.

Twenty months in, the program is still compounding. This is the story worth showing next to the outliers — the dependable, unglamorous channel most companies will actually build.
