SectionWhat's included

What a content copywriting retainer ships with.

A retainer that replaces a small in-house team — calendar, voice, drafts and edits — without the hiring overhead.

  • Monthly editorial calendar agreed a month in advance.
  • Long-form blog posts (typically four a month, 1,500 — 2,200 words each).
  • Weekly newsletter drafted in your voice, scheduled to your stack.
  • Social content set — LinkedIn or short-form, four posts a week.
  • Two web page rewrites a quarter, scoped at the calendar review.
  • Named editor of record — one person, one inbox, no rotation.
  • Monthly performance review against traffic, engagement and conversion.
  • Voice document and style sheet updated quarterly.

What our clients say.

Twelve months in and we're writing less in-house than we were before — and publishing more. The calendar runs itself; we just sign off the headlines.

One editor of record. One inbox. One voice across blog, newsletter and LinkedIn. That last point is what every agency promises and nobody else has actually delivered.

Organic traffic up 220% across the engagement. More importantly, the newsletter open rate sits at 48% — readers actually want what we send because the calendar is honest about what each piece is for.

SectionThe detail

More about our content marketing retainer work.

Our content marketing retainer is the rolling engagement most of our long-term clients sit on — a monthly content retainer covering blog posts, newsletters, landing pages and any longer-form pieces the brand needs across the year. We act as the full-service copywriter, or as an extension of an in-house team that's overstretched. Most retainers run between three and twelve months at a time and renew rolling.

What a monthly content retainer actually looks like

A typical monthly content retainer covers four to eight blog posts, two newsletters and one longer piece — a guide, a research note, a case study — each month. The work is briefed two weeks ahead and shipped on an agreed cadence. An ongoing content writer is assigned and held for your account, so by month three the voice match is automatic and the briefing time drops by about half compared to month one.

Working with a content marketing agency on retainer changes the economics of in-house. We run a single editorial meeting per month, hold a shared calendar against your campaign plan, and route work through a single project manager. The team has run retainers continuously since 2022; the longest current client started in March 2023 and still ships eight pieces per month with us.

Blog newsletter retainer work, and where the model breaks

A blog newsletter retainer is the most common shape — four blogs and two newsletters monthly, with the newsletter pulling traffic into the blog. It works for content-led B2B, education, publishing and professional services brands. The retainer model breaks for brands that need fewer than two pieces a month (better priced as one-offs) or for brands whose content needs are wildly variable month to month — for those, we propose a discounted block-of-hours arrangement instead.

Deliverables: clean Google Docs drafts, suggested meta data, monthly performance review, a quarterly editorial planning session, and copyright assignment on every piece.

SectionFAQ

Questions we are asked.

Short, honest answers. Anything else, send to contact@ebookwriting.ai.

What does the starting figure include?

At ebookwriting.ai, the starting content retainer of $1,800 per month covers a defined content package — typically a mix of long-form posts, landing-page copy, and supporting short-form pieces — with research, a voice document, two revision rounds per asset, and SEO metadata.

How long does a content package take?

Three to six weeks for a typical opening package. Ongoing retainers are planned a month at a time with a written editorial calendar.

What if a piece doesn't fit the calendar?

Two revision rounds are included on every asset. If a piece is genuinely off-brief we'll re-scope it rather than force a fix — the editorial calendar is a working document, not a contract.

Who owns the work?

You do. Copyright transfers on delivery, and the content is yours to publish, repurpose, or syndicate without attribution to us.

How is content delivered?

A Google Doc or Word file per asset, with body copy, headings, meta titles, meta descriptions, internal-link suggestions, and image placement notes. CMS publication can be added as a separate line item.

Can the content work across both SEO and brand-led channels?

Yes. We plan the calendar so every asset has a primary job — search visibility, audience trust, sales support — and a secondary one, which keeps the brand voice consistent while the SEO architecture does its work underneath. We'll set the balance out clearly in the proposal.
