Campaign Banners in Gmail Signatures, Company-Wide

Run scheduled, targeted marketing banners under every employee's Gmail signature, deployed automatically, measured per click.

How Sincerely works →

01

The channel you already pay for

Your team's outbound email reaches customers and prospects with ~100% deliverability and open rates no newsletter will ever see. A signature banner puts your webinar, launch or case study under every one of those messages, politely, in context, without a single extra send.

02

Why this needs automation

Banners date. A '#MarchWebinar' banner in a May email does negative marketing. Sincerely campaigns have start and end dates: banners appear on schedule, disappear on schedule, and the extension re-syncs everyone's Gmail within hours, nobody is asked to update anything, ever.

03

Measured like a real channel

Every banner click routes through a short tracked link: clicks per campaign, per team, per day, with UTM parameters appended automatically. Email-scanner clicks are filtered so the numbers are real. No open-tracking pixels, clicks only, documented publicly.
