Marketing Monthly Newsletter Template

TL;DR. A marketing monthly newsletter is sent on a monthly cadence to subscribers, leads, and prospects and follows the same three-section structure each issue: an industry trend, a case study or blog roundup, and an upcoming webinar or event. The best marketing monthly newsletters earn opens by sticking to that predictable structure and trimming filler — three sections, scannable in under a minute.

When to send a marketing monthly newsletter

• The first business day of every month.
• When you have at least one update worth sharing in each of the three sections (an industry trend, a case study or blog roundup, an upcoming webinar or event).
• To subscribers, leads, and prospects who opted into your marketing updates.

What to include in a marketing monthly newsletter

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

Subject line examples

• "{{first_name}}, your monthly Marketing newsletter is here"
• "What’s new at {{company_name}} this month"
• "3 quick marketing updates this month"
