Can I keep a swipe file of intros and CTAs?

Yes. Pin the openers and CTAs that worked and group them on a board. Pinned clips are unlimited, so your swipe file can grow without limit.

How do I paste a saved section quickly?

Press Cmd+Shift+V, type part of the snippet's name, and paste. The paste stack also lets you queue several sections and drop them in order.

Is my unpublished newsletter copy private?

Yes. ClipHistory stores everything locally with no account or cloud sync. Only optional AI transforms send text, and only to the provider whose key you supplied.

Does it cost a monthly fee?

No. It's a one-time $19.99 purchase for a 12-month license with no auto-renewal.

Store Newsletter Copy on Mac

A newsletter is a format with a lot of repeating parts: the welcome line for new subscribers, the recurring section headers, the sponsor disclosure, the unsubscribe nudge, the sign-off, the "reply and tell me" CTA. If you rebuild those from memory every send, you waste time and drift into inconsistency. Storing your newsletter copy as reusable blocks keeps each issue fast and on-brand.

ClipHistory is a local clipboard manager for macOS that stores reusable text as snippets and groups it on boards. It runs on macOS 12+, is a universal binary for Apple Silicon and Intel, and is signed and notarized by Apple.

The recurring blocks worth saving

Map your newsletter's structure and save each fixed piece as a snippet:

Intro / greeting lines (and a separate welcome for first-timers)
Section headers you use every issue
Sponsor / disclosure language
Standard CTAs — reply prompts, share asks, link-to-archive
Sign-off and signature
Footer text and unsubscribe wording

Once saved, building an issue's skeleton is a few pastes, leaving you to focus on the actual content that changes.

Keep a swipe file of openers

Strong openings are hard to write on demand. Keep a board of intro lines and hooks that worked. When you start an issue, browse the board, pick or adapt one, and you're past the blank-page moment. Because pinned clips are unlimited, your swipe file can grow indefinitely.

Recall everything with one shortcut

Press Cmd+Shift+V to open ClipHistory, type a few letters of a section's name, and paste. Your last 150 copied clips are also there and searchable, so a link or line you grabbed earlier while drafting is easy to retrieve.

Boards for issues and series

Boards let you organize beyond single snippets:

A "Newsletter — templates" board for your reusable sections.
A board per series or theme if you run recurring formats.
A "Swipe" board for openers, subject-line ideas, and CTAs that performed.

This keeps the reusable structure separate from the creative raw material.

Rewrite and tighten with AI

Newsletter copy benefits from quick polishing. ClipHistory's AI transforms use your own API key from one of five providers (Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint):

Rewrite a CTA into a fresher phrasing
Summarize a long update into a scannable blurb
Clean copy you pasted from a doc with broken formatting
Translate a section for a bilingual list

You supply the key, so you control the provider and the cost.

Assemble an issue with the paste stack

When you build an issue, queue the intro, the section headers, and the sign-off in the paste stack and drop them in order. You lay down the structure in seconds, then write the parts that change between sends.

This separation — fixed scaffolding pasted in, fresh content typed by hand — is what keeps a newsletter both consistent and timely. The reader gets the same familiar shape every week, which builds trust, while you spend your energy on the part that's actually new.

Reusing copy across issues

Newsletters cannibalize themselves constantly: a link you shared last month becomes relevant again, a CTA that performed well deserves a rerun, a paragraph from a past issue fits this week's theme. Because ClipHistory keeps your last 150 copied clips searchable, you can pull up something from a recent issue by typing a word you remember. For older material worth keeping permanently, pin it or save it to your swipe board so it's never more than a search away. Over time this turns your back catalog into a reusable asset instead of a pile of sent emails you'd have to dig through manually.

A practical habit: when you write a section you suspect you'll want again — a particularly clean explainer, a CTA that fits your voice — pin it right away rather than hoping to find it later. The cost of pinning is nothing, and pinned clips are unlimited, so there's no reason to be stingy. The clips you never reuse cost you nothing either; they simply age out of the 150-clip buffer.

Your subscriber copy stays private

Draft issues, unannounced sponsors, and unpublished offers shouldn't live in someone else's cloud. ClipHistory keeps your snippets and history local — no account, no sync server, no telemetry of your content — and works offline while you draft.

A simple system

Open your last few issues and copy each recurring block.
Save them as named snippets and group them on a "Newsletter — templates" board.
Start a "Swipe" board for openers and CTAs that worked.
Each send: queue the structure in the paste stack, paste, then write the new content.
Run an AI rewrite on any line that feels stale.
