How to Use Mail Drop on iPhone(Step-by-Step)

by Christine Smith • 2024-01-11 10:27:00 • Proven solutions

With Mail Drop iPhone can send large files to the recipients via email attachments. In most cases, these gigantic files are Full HD (1080p) or Ultra HD (4K) video footages in High-Efficiency Video Coding () format that have been recorded via professional or 4K cameras.

Considering the above, here you will learn what is Mail Drop on iPhone and how to use Mail Drop on iPhone to send large attachments to the target email recipients. After reading this, you will have a clear understanding of the concept of the Mail Drop feature, its limitations, and the best workaround if your iPhone refuses to send a file as a Mail Drop attachment.

Part 1. What is Mail Drop on iPhone

Available in any iPhone running iOS 9.2 or above, Mail Drop is a feature that uses iCloud storage of your Apple ID, and automatically comes into play when you attempt to use the Mail app on your phone to send a file as an email attachment, but the size of the file exceeds the limit supported by your email service provider. For example, if you have configured your Gmail account with the Mail app on your iPhone, and the file that you want to send is larger than 25 MB (25 MB is the maximum file size that Gmail allows its users to send via mail as an attachment), the app prompts you to use Mail Drop instead.

With Mail Drop on the iPhone can easily send the files that are as big as up to 5GB in size. When these files are sent via Mail Drop, they remain available for the target recipients for the next 30 days, after which they are automatically removed from the server.

Part 2. How to Use Mail Drop on iPhone in Easy Steps

The process of using Mail Drop on the iPhone is extremely simple and straightforward. What you do is, you compose your email and attach a large file normally. However, you are prompted to use Mail Drop to send the attachment when you tap the “Send” icon, and the Mail app detects that the email server it is configured with does not support the size of the file you are trying to transfer. You can follow the steps given below to use Mail Drop on iPhone while sending a large file to the recipient(s):

Step 1: Launch the Mail App and Compose a New Mail.

On your iPhone, tap the Mail icon to launch the app, tap the New Mail icon from the bottom-right corner, populate all the fields with their relevant information, and type your message in the available box.

Step 2: Tap the Attach File Icon and Upload a File.

Once you are done typing your message, tap the More icon (<) from the right corner of the suggestion bar, tap the Attach File icon, and locate and tap the file you want to send as an attachment. (A small part of 45MB of a large video file is used for this demonstration.)

Step 3: Tap Send and Choose Mail Drop for File Attachment.

Tap the Send icon (Up arrow) from the top-right corner, and tap Use Mail Drop from the box that pops up at the bottom to use Mail Drop on iPhone to send a part of a large video file to the recipient(s).

tap send

Part 3. When Can’t Use Mail Drop to Transfer Files

As mentioned before, Mail Drop on iPhone automatically comes into the picture when the email service provider has specified some size limit for the files a user can attach to a mail. However, even Mail Drop has certain limitations. The feature allows a maximum of 5GB of the file(s) per the attachment and a maximum of 1TB of overall files regardless of the recipients or number of emails.

With that said, listed below are certain situations when you cannot use Mail Drop on iPhone to transfer the files:

  • If the file you are trying to send is larger than 5GB in size
  • If the overall limit of file transfers hits the threshold of 1TB

For optimum utilization of your iCloud space, the files sent via Mail Drop are automatically removed from the server after 30 days. This means you can start using Mail Drop on iPhone again to send more files to your friends and colleagues as soon as the lifespan of attachments has expired, i.e., after 30 days of sending, and iCloud has recovered its space by removing the file(s) from its server.

Part 4. Best Alternative Recommended to Compress Large Files for Email

Yes, Mail Drop on iPhone does a pretty good job when it comes to sending large files to the recipients via emails. But what if its efficiency isn’t sufficient because you need to send some videos that exceed the size limit defined for Mail Drop? The answer is, Wondershare UniConverter!

Although you can use the built-in editor to trim the videos in order to decrease the file size, this cannot always be the case as many times the footage may contain important details that you cannot afford to lose. This is where the video compression process comes into the picture. In fact, there are two methods to compress video files using Wondershare UniConverter, and both of them are explained below:

Method 1: From the Convert Window

Step 1 Click Add Files and Import a Large Video.

Start Wondershare UniConverter on your computer, click the +Add Files icon from the Video Compressor window, use the Open box to browse and select the video you want to compress, and click Open from the bottom of the box to import the file to the UniConverter’s window.

Step 2 Click the Compress Icon and Reduce the Video Size.

Click the Compression icon from under the Target section of the video you imported, and move the slider on the Your preferred output size box to the left to reduce the size. Notice how the values in the other fields change automatically when you move the slider.

click the compress icon

Step 3 Click OK to Save the Changes and Convert the Video.

Click the Preview button to preview the modified video for the quality you can expect post-compression (optional), and click OK to save the changes if the new size seems acceptable to be transferred via Mail Drop on iPhone. You can now choose your preferred output format from the Output Format menu from the bottom-left corner and click Convert to compress the video.

save the changes

Method 2: Using the Compress Video Box

Step 1 Click Video Compress on the Video Compressor Tab.

Launch Wondershare UniConverter if it isn’t already started, go to the Video Compressor tab from the main menu.

use the compress video box

Step 2 Click Add Files and Compress the Video.

Click the +Add Files icon, and use the method explained earlier to import the video you want to compress. Next, move the slider (from the top-right area of the box) to the left to reduce the size of the video. As before, notice the changes in the values in the other fields to adjust the slider accordingly.

Step 3 Define the Output Folder and Begin Compression.

Use the File Location field to define a folder on your PC where you want to save the compressed video, and click Compress from the bottom to begin compressing the footage that can be used to transfer via Mail Drop on iPhone. You can always use the Preview button to check the video quality you can expect post-compression.

compress the video


As long as your video is of 5GB or less in size, you can use Mail Drop to transfer it without making any changes. On the other hand, if the clip exceeds the given size limit, Wondershare UniConverter is the most recommended program to help you compress the footage before sending it to the target audience via Mail Drop iPhone has in the Mail app.
