Most businesses send updates — but still struggle with client engagement. The problem isn’t the content. It’s the type of email. The 4 Types of Marketing Emails That You Should Know
At Singularity, we discovered a clear framework that helps structure every email with purpose: Newsletter, Conversion, Retention, and Promotional. Each type targets a specific stage in the client journey — and until recently, we were only using one.
Here’s what each type offers:
Newsletter Emails Keep clients informed. These are ideal for sharing blog updates, case studies, and AI tools.
✅ Builds brand authority and nurtures trust.
Conversion Emails Designed to turn interest into action. Used for onboarding new leads or offering demos.
✅ Drives sign-ups and client acquisition.
Retention Emails Sent to existing clients with value-adds — like feedback requests or new tool recommendations.
✅ Strengthens long-term relationships and increases lifetime value.
Promotional Emails Time-sensitive messages with clear calls-to-action, like prompt access or limited features.
✅ Drives urgency and immediate engagement.
The Gaps We Didn’t See Until Now
Doing our newsletter system wasn't enough.
We weren’t using conversion emails, so new prospects often slipped away after the first contact.
Retention emails were missing — we lacked consistent re-engagement or feedback loops.
No promotional emails meant we weren’t creating urgency around new tool launches or updates.
This created friction in our workflow: slower onboarding, disengaged leads, and missed chances to highlight our engineering breakthroughs. After learning this framework from Chase Dimond, we’re actively expanding our email process to include all four types — increasing clarity, speed, and impact in how we communicate with engineers and clients.
We’re applying AI to engineering.
