Years ago, you need to depend on the post offices to send or receive any documents. But email attachment is a blessing for today’s generation who does not need to wait for days to send any documents. You can share your vacation pictures with friends and family or send your resume to your dream job instantly. You can attach pictures, spreadsheets, PDF, doc, GIF and videos with your emails. But Yahoo limited the size of the attachment to 20 MB. If your attachment is more than 20 MB, then you can upload it to Dropbox and share the link in your email.
Please find here the steps to add the files, photos, documents and GIFs in your emails.
The preview attachment option is a time and data saving option.
Yahoo scans all the attachment by default. So you can download them without any worry. Here are the steps to download it.
