You and your customers can upload attachments to your Re:amaze conversations using a simple drag and drop feature located below the conversation reply box, or by clicking "click here" in the same section.
Re:amaze has a file size limit of 100MB, so you can upload and send big files as long as your customer can receive them. If you wish to attach a picture or file in line, simply use markdown to link the picture or file. If you're doing this, make sure that the file or image is hosted elsewhere online. Re:amaze supports most file formats ranging from documents to PDFs and from Photoshop files to spreadsheet file types.
