Besides the maximum attachment size, there are other important factors to consider when it comes to the size of your email. These include:

1. Spam Score

The spam score determines the likelihood collecting data efficiently in the field: annotated visuals of being marked as spam. Email providers use the spam score to filter potential junk mail and protect users from phishing attempts and spam. This score can be greatly affected by the size of an email; larger emails typically have higher spam scores.

2. Rendering Issues

When you exceed the maximum size of an email attachment, it can lead to various problems.

• Email Client Incompatibility: Not all email clients are created equal. Some may struggle to handle large files, which can lead to display issues the manager nes to analyze or email not opening.
• Slow Loading Times: Large attachments can cause emails to load slowly, especially on devices with limited bandwidth, which could lead to your recipient abandoning the email entirely.

In many email clients, a large email body may be rendered incomplete. In this case, your recipients may receive the content of your email truncated and only partially viewable images. Your recipient may be offend and leave a bad impression of you.

How to Send Large Files That Exceed the Attachment Size Limit?

File limits can cause some problems, especially text services if you need to send multiple files to multiple people. But there are simple ways to send large files without worrying about problems that could occur if the total size of the files you’re sharing exceeds the limits. These include:

1. Compress the file

You can use file compression software (like WinRAR or 7-Zip) to compress your file into a zip folder. Doing so will allow you to send multiple large files (like videos, for example) without worrying about attachment limits. You also don’t have to upload individual files with this method. Just upload the compressed zip folder to a message and click send.

2. Use Cloud Storage Services

A common way to get around the email size limit is to use cloud storage services. You can share large files with anyone by uploading them to services like Google Drive, Dropbox, or OneDrive and giving your recipient access via their email address.

3. File Sharing Links

When you upload a folder containing large files to a cloud storage service, you can create a link to those files. These links also allow you to send access to your recipients, which can even allow them to edit the file.

Simply send your recipient a link to your file and they can access it from there.

4. Splitting Large Files

You can get around the attachment limit by sending multiple emails that are within the MB allow per email. However, this can spam your recipient’s inbox, so make sure you only do this if you need to split attachments into 2-3 emails.
