Buttondown is a newsletter tool that makes it silky-smooth to add PDFs, CSVs, and more to outgoing emails

Drag a file into your email draft, and it ships with your newsletter. PDFs, CSVs, images, audio — whatever your subscribers need.

Send more than just prose.

Newsletters aren't always just text. Sometimes you need to share a lesson plan, a report, a slide deck, or a dataset. Buttondown makes it as simple as dragging and dropping:

• PDFs and documents. Share reports, guides, whitepapers, or worksheets alongside your writing.
• Spreadsheets and data. Send CSVs or Excel files for readers who want the raw numbers.
• Media files. Attach images, audio, or video for subscribers who want more than words.

Your subscribers see the attachment at the bottom of the email, right where they'd expect it. No third-party file hosting, no expiring links — just a file, attached to an email.

Buttondown is the last email platform you’ll switch to.
