From brief to report in one place

A campaign usually fails before it launches: the goal is vague, the budget is split by habit, or the links are not tagged, so nobody can tell later which channel worked. Start with the campaign brief and the budget allocation calculator, then build every link with the UTM builder so your analytics report matches the plan.

Once ads are running, ROAS tells you how much attributed revenue each unit of ad spend brings back, and the frequency calculator shows how many times, on average, each person in your audience has seen the ad in the period.

For owned channels, the email list growth calculator projects the next six months from your monthly sign-ups and churn rate, which shows whether your newsletter is actually getting bigger or just replacing the people who leave.

Frequently asked questions

Are these marketing tools free?

Yes. All ten marketing tools are free and need no account. Your drafts stay in your browser.

What is a good ROAS?

It depends on your margin. A business with a 25% gross margin needs a ROAS of at least 4 to break even on ad spend, while a business with a 75% margin breaks even at about 1.33. Work out your break-even ROAS as 1 divided by your gross margin and compare the calculator's result with it.

Why should I tag links with UTM parameters?

UTM tags tell your analytics tool which source, medium and campaign sent each visitor. Without them, paid social, newsletters and partner links are often lumped together as direct or referral traffic.

Can I export the content calendar?

You can copy the finished four-week calendar or print it. It is plain text and table output, so it pastes cleanly into a document or spreadsheet.
