Attach files to your Inbox replies

Your Inbox replies can carry files now, not just text. So when a subscriber asks for a PDF, an image, or your media kit, you can send it without ever leaving the conversation.

It's a new paperclip in the reply composer: click it, pick a file, and it rides along with your reply — the same attachments you can already add to your emails. Once the reply sends, the file shows up as a download chip in the thread, so you can always see what you sent.

Reach for it whenever the conversation calls for more than words — a media kit for a prospective sponsor, a corrected PDF for the reader who flagged a typo, a quick screenshot to settle a question.

It builds on replying to conversations from your Inbox, and it's live now on every plan that includes attachments — open a conversation and give it a try.

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