NH Oil Undercoating · Evergreen Annual Content Plan
An always-on content engine, built around your seasons.
The plan we're proposing: a year of email built on the rhythm of rust. Eighteen sends that follow the temperature from the spring thaw through the peak booking rush, each one teaching first and selling occasionally. Four pillar blogs sit underneath them, so every email has something genuinely useful to link to. Timed for the Northeast and Midwest — where roughly 90% of the business is.

Evergreen total
18 emails / year
Spring 4 · Summer 4 · Peak 7 · Winter/Maint. 3.
Peak runs denser, and includes the two annual booking-pressure sends (mid-Aug + early Sep). Reusable each year; ad hoc promos sit on top.
Optional: a quarterly newsletter (4/yr) can sit on top.
Educate-first email only works if there's something worth linking to — and NHOU already has a deep evergreen blog and YouTube library. Most of the 18 emails can point to an existing post or how-to video, and three of the four pillar blogs can be refreshed or assembled from existing posts rather than written from scratch (summer is the only thin spot). Each pillar publishes a month ahead of its season as the cornerstone the emails link to, doubling as year-round SEO and ad landing pages. One rule: the pillars never hold up the mid-August and early-September booking emails. Those two get built and sent first — the fall pillar can follow behind them.

01
Booking emails come first
The mid-August and early-September booking sends are the priority — built and scheduled before anything else, because a slot booked before October is the biggest win of the year. Pillars and the rest follow behind them.
02
Emails teach, then point
Most sends are genuinely useful and link to the blog. Selling is occasional and well-timed. Every consumer CTA lands on the same two choices: buy the product, or use the Applicator Locator to find someone local and book.
03
It gets smarter over time
Content tailors by region (northern rust-belt vs southern coastal — Northeast & Midwest are core) and by sub-segment (e.g. boat & trailer owners, who prep in April/early May — reached with their own targeted send). Once the list is segmented, applicators and retailers move to their own track; this consumer track keeps the same products, different message.
