Sending And Receiving Email Attachments For Beginners

Email AttachmentsAn attachment is a file (document or program) attached to an email.

In many email applications (e.g. Windows mail ) a picture of a paper clip indicates the presence of an attachment.

Attachments are used to send supporting files, photos etc that is supplemental to the email.

Are Attachments Safe?

All attachments should be treated as unsafe, and not be opened unless you are sure that they are virus free.

You should always save an attachment to your hard drive, and scan with a virus checker before opening it.

Note: Gmail and Yahoo automatically scan attachments for viruses before placing them in your inbox.


Blocked Attachments- Why Some Attachments Aren’t Downloaded

Email providers and email clients may block certain attachments.

Executable files like .exe, .bat, .cmd etc are usually blocked.

If you need to send these types of files you can rename them or zip them or use a file transfer service.

You may also find that encrypted attachments are also blocked as the provider cannot virus scan encrypted files.

Downloading and Opening Attachments

If you use Gmail,Yahoo Mail, with a web browser client (webmail) or a mobile phone email App then downloaded attachments are normally placed in a folder called downloads in your user profile.

Note: You should always download and virus check an attachment before opening it.

Saving Attachments

For desktop clients like Outlook you can save the attachment to your file system by right clicking on the attachment icon and selecting save as.


Note: Saving an attachment does remove it from the email and that the attachment is still stored with the email.

Printing Attachments

To print an attachment you will need to open it. This usually involves saving it to your computer first.

The attachment will be opened using a compatible program e.g. pdf attachments are opened with Adobe Reader.

Note: you may need to install a supporting application to read and print some attachments.

Forwarding Email With Attachments

If you forward an email message most email client will,by default, forward any attachments with the email.

If you don’t want to forward the attachments you will need to remove them before sending the message. Most email clients allow this.

Outlook (2003) shows the attachments on a separate line, and so all you need to do is highlight the ones you don’t want to forward, and hit delete.


Sending Attachments with Email

Just click the icon and you should get a browse window that lets you locate the file or files that you want to attach.

Remember that some attachment types may be blocked so be careful what you attach.

Blocked attachments and large attachments can be sent using a file sharing service like OneDrive, Dropbox or Google Drive.

Sending Large Attachments and Blocked Attachments

Email providers have attachment size limits, and even though they are constantly increasing they are not uniform across the Internet.

Gmail and Yahoo currently have a 25 Mbyte limit

This means that your provider may allow the attachment, but it may be blocked at any other email server on its way to its destination.

Fortunately there are now many solutions for sending large files, which are just as easy as sending them by email.

Most systems involve you transferring your files onto a website (which the provider provides), and then anyone who wants to receive the files can download them from the website.

To send the files you usually select which files your would like to send, and the email addresses of your desired recipients.

The recipients receive an email with a download link, clicking the link starts the download process.

By using these mechanisms you will never need to worry again about emails being rejected because attachments were too large or because they are encrypted, or blocked!

Here is a quick diagram that illustrates the process..


Sending Encrypted Email Attachments

If you need to send confidential attachments like tax returns etc then you can easily protect them by using file encryption software to encrypt them before sending.

There are many file encryption tools you can use and the sender and receiver must use the same tool.

The easiest one is the free open source 7ZIP tool which is a file compression tool that also supports encryption.
