Why is there a sponsored line in that email?

The person who emailed you uses SigMint. They chose a product they wanted to recommend, and SigMint adds one small, clearly-labeled line for it under their signature. If someone clicks the link and ends up becoming a customer, the sender earns a commission — that is the whole arrangement.

The sender picked it. Nothing appears in their signature unless they chose it — there is no automated ad rotation and no third party deciding what shows up next to their name.

It is always labeled. Every SigMint line starts with “Sponsored:” — the label you clicked to get here. If it is not labeled, it is not from us.

About the link itself. The link goes through SigMint so the sender gets credit for the click, then continues straight to the product's real website. We count the click; we do not collect anything personal about you along the way.

And your email? SigMint connects only to the sender's signature settings. It cannot read their email — or yours.
