"Only 3 hours left" but the sale runs until Sunday night. A countdown that doesn't match the real end time is a misleading urgency claim.

Evidence requiredASA CAP 3.7

"40% off everything" means every product is reduced by 40%. You must hold evidence of this before sending, or say "up to 40% off".

Questions

The things people ask first.

What does Sendwize actually do?

It checks your marketing before and after it goes out: the copy, the landing pages, your contact lists, your suppliers and your website, against UK advertising, consumer and data protection rules. Every issue lands on one list, ranked by what it could cost, with the fix next to it.

How much does it cost? Is there a free plan?

£299 a month on a 12-month plan, or £2,990 up front for the year, with all seven tools. There's no free plan. The check on this page is a preview of the AI Copy Checker, so you can see how it works before you sign up.

Can we use it for more than one brand?

Yes. A plan covers one brand, and you can add more brands for an extra fee. Get in touch and we'll set it up.

Who is it for?

UK marketing teams, agencies and small businesses that send email, SMS or ads and don't have a lawyer reviewing every campaign. It's for the person who presses send, and whoever signs it off.

Is this legal advice? Does it replace a lawyer?

No. Sendwize is software, not a law firm. It finds and ranks compliance issues so routine campaigns don't need a legal review. For advice on your own situation, speak to a solicitor who specialises in UK data protection and consumer law.

How accurate is it? Will it catch everything?

Fixed rules find the issues and AI explains them, so the same copy gets the same answer every time. The rules come from published regulator decisions and are updated daily. No tool catches everything, so treat it as a thorough first check, not a guarantee.

Where do the £ figures come from?

From Sendwize's own exposure algorithm. It starts from what organisations were fined for the same kind of issue in published decisions, then adjusts for your size, sector, the people and data affected, your records and your history. Every figure shows the factors behind it and the closest real cases. The ASA doesn't fine, so for ad claims we show the ruling and the referral risk instead of a number.

We write copy with AI. Is that a problem?

Not on its own, but AI writes what you ask for, not what the rules require. In 2026 the ASA ruled against a Midnite gambling ad made with AI because nobody told it about the under-25 rule. Check AI-written copy the same way as anything else.

If we get a complaint, can we show we checked?

Yes. Every check, fix and sign-off is dated and saved to your compliance record, so whoever approves a send can see what was checked and when.

What happens after a campaign goes live?

Campaign Defence checks the pages your campaign links to every day while it runs and tells you if anything changes after sign-off. You also get a weekly digest and new regulator decisions in your feed.

Which email platforms does it work with?

Any that can export a CSV. List Intelligence and Audience Read work from your platform's exports, so there's nothing to connect.

What happens to the data we upload?

Uploaded lists are used to run the check you asked for and are tied to your account. The preview check on this page doesn't keep the text you paste.
