Agency Quarterly Update Newsletter Template

TL;DR. A agency quarterly update newsletter is sent on a quarterly cadence to clients, prospects, and former clients and follows the same three-section structure each issue: a client win or case study, a new service offering, and an industry insight. The best agency quarterly update newsletters earn opens by sticking to that predictable structure and trimming filler — three sections, scannable in under a minute.

When to send a agency quarterly update newsletter

• The first week of every quarter.
• When you have at least one update worth sharing in each of the three sections (a client win or case study, a new service offering, an industry insight).
• To clients, prospects, and former clients who opted into your agency updates.

What to include in a agency quarterly update newsletter

• Section 1 — a client win or case study: 2–4 short items with one-line value props, not changelog dumps.
• Section 2 — a new service offering: one named example with a clear outcome and a link to the full story.
• Section 3 — an industry insight: 2–3 things in flight or coming up next, framed as planning context.
• One primary CTA — usually "read the full quarterly update" or "see what’s new."

Subject line examples

• "{{first_name}}, your quarterly Agency newsletter is here"
• "What’s new at {{company_name}} this quarter"
• "3 quick agency updates this quarter"
