About this email
This email serves as a comprehensive update and engagement communication from Customer.io's partnership team, targeting partners and users. It is structured with headline sections including a 2025 partner kickoff event invitation, product updates featuring a new campaign builder and SDK upgrades, as well as new partner tier information and upcoming event schedules. The tone is enthusiastic and collaborative, aiming to inform and motivate recipients to participate in events, explore new product features, and engage with the partner program in the coming year.
Customer.io journey
Why this works
**Why this works.** The subject line says "news, delivered" instead of naming a specific feature or event, which signals that the email contains curated updates relevant to the recipient's role, not a single ask - this makes partners open it expecting value rather than a pitch. The pattern here is "positioning the email as a digest, not a demand"; you can lift it for any partner or stakeholder communication where you need to stack multiple announcements and keep open rates high by making recipients feel informed rather than sold to.
