A gram may not be much, but compare it to a byte: schlepping 30 kilograms over the Alps is an arduous, rewarding task; sending 30 kilo-bytes by email around the world is nothing. 30 megabytes, then again, might be too much — too much for Yahoo! Mail. Let's find out what the limits are and what Yahoo! Mail can stem.

Yahoo! Mail Message and Attachment Size Limits

Yahoo! Mail lets you send emails up to 25 MB in total size. This size encompasses both the message itself and all its attachments.

How Can I Reduce the Size of a Message?

Yahoo! Mail has a message size limit, but there are ways around it. If a message you are about to send in Yahoo! Mail exceeds the limit, you can employ a number of strategies to cut it down to size:

  • Compress attached files using an archiving utility.
    • Many files you share — such as photos, videos, or sound files — are already compressed, so this will not help much. Compression can be useful for spreadsheets and word processing documents, for example, though.
  • If you have multiple files to send, you can attach them to more than one message.
  • Use a file sharing service such as Dropbox to send the files.

Sending Larger Files with Yahoo! Mail

To send a file larger than Yahoo! Mail (or the recipient's email service) allows, you can use a file sending service or share with Dropbox right from Yahoo! Mail:

  1. Click the downward-pointed arrowhead next to the Attach File paperclip icon while composing a message in Yahoo! Mail.
  2. Select Share from Dropbox from the menu that has appeared.
  3. If your Yahoo! Mail account is not yet connected to Dropbox:
    1. Click OK under Share from Dropbox.
    2. Now click log in. You can also use the form to create a new Dropbox account using your Yahoo! Mail address (or any other email address).
    3. Enter your Dropbox username and password, then click Sign in.
    4. Click Link account under Link your Dropbox account to Yahoo and skip the sign in when using Dropbox on Yahoo Mail.
  4. To send a file already in your Dropbox:
    1. Use Search Recent files or your Dropbox folders under Files to locate the file.
  5. To send a file not yet in your Dropbox:
    1. Click Upload.
    2. Find and highlight the files you want to upload from your computer.
    3. Click Choose. You can, of course, also upload using a synchronized Dropbox folder on your computer or device.
  6. Click to highlight the file you want to share in the email from Yahoo! Mail.
    1. You can highlight to select multiple documents.
  1. Click Choose.
  2. Continue composing the email and eventually send it.
    1. Yahoo! Mail has automatically inserted a link to the shared Dropbox file or files.
    2. You can make the link appear smaller by hovering the mouse over the downward-pointed arrowhead in it and selecting Small from the menu
    3. To move a link to the bottom of the message (and outside of the message's text itself). Click the downward-pointed arrowhead inside the Dropbox link. Then select Move to bottom from the menu that has appeared.
