Do4U writes a newsletter draft from a short description, a list of article addresses, or both. You can mark one address as the main article: it comes first with a longer teaser, and the others follow as shorter recommendations. You choose the language, tone and length, and you can name the audience and occasion. You get subject lines with a preview text, an introduction, a teaser with a link for each article, and a closing. The code builds every link from your list. You copy the result as text or as email HTML, or download the HTML. It is a draft that you check before sending. Do4U sends nothing.

Questions and answers

Does Do4U send the newsletter?

No. The tool sends nothing and has no recipient list. You copy or download the draft and send it with your own mailing tool. Before that, replace the placeholders for the unsubscribe link and the sender address, and check facts and links.

Where do the links come from?

Only from your address list. The code builds every link itself, so the AI cannot add another link target. Addresses in the short description are neither read nor linked. Texts with another address, with markup or with a figure that is not in your input or on the pages are removed. The result lists amounts and percentages from the text for you to check. A wrong statement can still stay in the text, so read the draft before sending.

What happens if a page cannot be read?

The address appears under “Not read” with the reason. With a note, the article stays in the draft; without one, it is left out. If no address can be read and there is no short description, the job ends and no credits are used.

Is my text stored?

Only as long as needed: 7 days on Free, 30 days with a package – or not at all if you choose not to store it. Processing happens on our own servers in the EU (Poland).

Can I use the result right away?
