What You Need to Know About Email Attachment Limitations

Email attachment limitations can be frustrating but there are usually ways around them and we took the time to explore all of them.

Security is increasing all over the internet just like cyber attacks are increasing. As a result, there are many more limitations when sending emails and you may find that your documents are not allowed through because of their size. Even though emailing is still one of the easiest ways to share documents with other people, you may find that actually sending them may create some road blocks. Before you send emails out, these are the limitations of various systems that you need to know about so you can ensure your emails are received.


Gmail is one of the most commonly used email systems and they limit the size of attachments in a single message to 25 MB. Gmail does make it a bit easy for you though by showing a warning that it is too large. Then, Gmail will automatically put the file in Google Drive and add the link to it in the message. The workaround for email limitations is built right into their email system but one thing to keep in mind is that you are limited to 15 GM of free storage on Google Drive.

Outlook and Hotmail

These Microsoft email servers are more generous than Gmail and allow you to attach up to 34 MB to a single email. They also make it easy when you go over that limit and do something similar to Gmail. If your attachments are over the limit, you are given the option to put them into OneDrive and send a link. One major difference between these services and those provided by Gmail is that the transfer and link is not automatic. You must choose for this to happen or your attachments will not be included in any way. You get 5 GB of free storage on OneDrive.

Yahoo and AOL

For both of these email services, you can send up to 25 MB through a single message, the same as Gmail. The difference is that this file size not only includes the attachment but also the text in your email. The workaround for these email servers are not as easy. If you do go over the allowed amount in a single message, there is a pop-up message that asks if you want to link your Google Drive or Dropbox account to Yahoo. Yahoo and AOL do not have their own storage components to directly link to your email accounts. These email accounts are not as intuitive and you are much more likely to have an email not reach your recipient while using them. That does not mean that the workarounds are not good options but they are not seamless so you have to put in more effort to ensure your emails and attachments are received by your intended recipients.


iCloud is an email provider for Apple and Microsoft. Their email service limits your attachments to 20 MB. If your attachment is larger than this, you can place the file in Mail Drop. Mail Drop will store your files for 30 days and has a maximum capacity of 5 GB.
