The maximum size of an email when it comes to sending and receiving is important, to determine that the size of your attached file/s won’t effect the safe receipt by the Recipient via their email server.

Maximum Size Of An Email

While the maximum size for emails is around 20MB, it is advisable to adhere to a rule of thumb and avoid sending emails larger than 7MB. By keeping emails under this size, you can ensure smoother transmission and mitigate the likelihood of delays or complications for both the sender and recipient.

Larger emails run the risk of timing out for the recipient, which could cause delivery problems, therefore this precaution is of utmost importance. You can guarantee more seamless transmission and reduce the possibility of delays or issues for both the sender and the recipient by limiting the size of an email.

Best Practices To Limit The Size Of An Email

When it comes to email size, adhering to our best practices will ensure messages are delivered effectively and efficiently. Here are some tips to follow:

Limit The Number Of Attachments

Limit your attachments and avoid attaching large files to your emails, whenever possible. Consider sharing files by using cloud storage services like Google Drive or Dropbox and including a link to the file in the body of your email.

Compress Attached Files

If you need to attach multiple files, compress them using file compression tools that you may already have on your PC such as ZIP or RAR, which will help to reduce their size before sending them.

Optimize Images For Email Transmission

Resize and compress images before adding them to your emails. Large images can significantly increase the size of your email, exposing you to the risk of delivery delays and potential issues for recipients with limited bandwidth.

Use Text-Based Content

Whenever possible, opt for text-based email content over heavy HTML designs or rich media. Plain text emails are smaller in size and load faster for recipients.

Avoid Excessive Formatting

Reduce your use of unnecessary formatting, fonts, and styling in your emails. These elements can enhance the visual appeal; however, they can also contribute to larger email file sizes.

Use Hyperlinks

Instead of embedding large images or multimedia files directly into your emails, opt for hyperlinks to web pages where your recipients can access content.

Evaluate Email Sizes

Before sending out mass emails or important communications, test your emails to ensure your communication is within acceptable size limits and render suitably across remote devices and different email clients.

Use Service Providers

Utilize email service providers that offer features you can use to manage large email campaigns. Some of these services offer functionality such as automatic resizing of images and attachments, to optimize email size and delivery.
