Free marketing tools that don't want your email first
Free marketing tools with no email wall: UTM builder, ad specs, subject line preview, CAC and ROAS calculators, safe zones and more.
TLDR
- Most “free tools” are lead magnets. You type a URL, then it asks for your work email before it shows you anything.
- These don’t. They open, you use them, and most run entirely in your browser, so nothing you type goes anywhere.
- We made them. They’re on savepad.app because they’re the little jobs you do between saving things.
Why no email wall
“Free tool, then enter your email to see your results” is the oldest trick in B2B. It works, in the sense that it gets emails. It also means everyone’s inbox is full of nurture sequences from a UTM builder.
So these are just tools. There’s a link to Savepad at the bottom of each page, and that’s it. If you like them, great. If you don’t sign up, also fine. Nobody’s getting a nurture sequence.
Ads
- Ad specs for every platform. Sizes, ratios, file limits and copy lengths for Meta, TikTok, LinkedIn, Google, YouTube, Pinterest, Reddit and X, checked by hand.
- Safe zone checker. Drop your Reel, TikTok, Story or Short in and see where the platform’s buttons and captions will cover it.
- Every ad library in one place. Search a brand across the Meta, TikTok, LinkedIn, Google and X ad libraries at once.
- Ad brief template. Fill in the brief, drop your reference ads in, download a clean PDF for the designer.
- Ad copy character counter. Live counts against every field’s limit, and where each platform cuts you off.
Numbers
- CAC calculator. Ad spend, salaries, tools and agency fees in, the real customer acquisition cost per channel out.
- CAC payback period calculator. How many months until a customer pays back what they cost.
- Break-even ROAS calculator. Your margin in, the ROAS you need to stop losing money out.
- Ad frequency calculator. Reach and impressions in, frequency out.
Email and links
- Subject line and preheader preview. See it in Gmail, Apple Mail, Outlook and on a phone, truncation and all.
- UTM builder. Campaign links with presets you can reuse, or a whole CSV of them at once.
- Tracking parameter remover. Strip utm, fbclid, gclid and friends off a link before you share it.
Pages and pictures
- Google snippet preview. Your title and description at Google’s real pixel widths, with the cut-off shown.
- Colour palette from an image. Drop an image, get its five main colours as hex, RGB and OKLCH.
- Screenshot mockup. Put a screenshot in a browser or phone frame on a nice background.
- YouTube thumbnail grabber. Every size of a video’s thumbnail.
- Bookmarks file converter. Turn a browser bookmarks export into CSV, JSON or Markdown.
The full list, including the ones still being built, is on the free tools page.
And the thing they’re next to
Each of these is a small job you do between saving references: checking an ad fits before you brief it, working out a CAC before you pitch a channel, cleaning a link before it goes in the deck. The references themselves go in your swipe file. The marketing resources post is the bigger list of everything else we’d bookmark.
