How many kb can i email

Technically, there is no message body limit in the SMTP protocol. Still, some providers have their own limits.

Many tests by various providers prove the correlation between email size and deliverability. In most cases, messages with a body over — KB trigger spam filters. So, the common recommendation is to keep email body size between 15 KB and KB.

Your recipients do not always have access to a high-speed connection, and a long-lasting message loading process might cause irritation. In addition, in many email clients, a large email body might be rendered just partially, and your recipient will see just parts of images or clipped content.

Notwithstanding the numerous limitations and hidden constraints, there are common rules on building well-performing emails. The first of these is to decrease and optimize email body size. Considering the above mentioned limits and dependencies, we have created a short email size optimization checklist. Here are the best practices for building a well-performing email in terms of size:. Even if you followed all recommendations and have crafted the perfect message, checking its size is not an easy task.

Whether you are coding a message in your app or preparing a template to send via Gmail, you need to use a third-party tool, actually send your message, or download it then to explore its size. If you use Mailtrap for testing your emails before sending them to your real recipients, you can easily check both the email body and attachment size.

As soon as your test message is trapped in your virtual inbox, the total email size is displayed along with the message headers. If your message has attachments, you will see a list of them with file names and sizes. Also, Mailtrap has email size limits, which depend on your billing plan. That 50MB attachment size limit was only for incoming email. So while you could receive emails with more information, you were still stuck with a restrictive 25MB limit for uploading. Gmail lets you share files up to 25 MB in size, where the size is determined by the size of the file on disk.

If you attach a file larger than 25 MB in size, it gets uploaded to Google Drive and Gmail places a download link to the file in the body of your email message. If you attach big files greater than 25 megabytes, the Gmail app uploads it to Google Drive and links to it instead of attaching it. However, even if you share files smaller than 25 MB , bypassing the need to use Google Drive , the actual email messages end up being around 50 MB in size, because of how an attachment file doubles in size when encoded into the format necessary for email file sharing MIME.

Long story short, the files you attach to your email generally double in size in Gmail due to how it encodes an attachment file. Also, note that the GMass size limit is applied to an individual email message, not all emails in aggregate. There are two simple methods to workaround the Gmail attachment size limit.

This is the default option for most people trying to share files that are larger than 25MB. When Gmail detects that your mail is larger than 25MB, it automatically uploads your attachments to Drive and adds a download link to it in your mail.

Sign up for Google Drive in your browser. Google Drive is a cloud storage and file sharing service that gives you a higher storage limit than a regular Dropbox account. The Gmail app will now add a download link to these attachments in your email. When recipients receive the mail, they can click on the link and will be redirected to these attachments.

If you have multiple big files that need to be uploaded, you can always compress them into a zip folder. Zip folders take up less place and are easier to transfer to other computers.

Mail drop apps like GMass can help users track Drive links. This service supports click-tracking to help you determine if a person has opened your Drive link or not. Note — To prevent your links from looking like phishing links, GMass does not track links where the anchor text itself is the URL.

We recommend that the sender re-labels their Google Drive download link to avoid this issue. However, until Google releases a new update that actually helps a sender with uploading files users can always send Drive links from their desktop device or their Android or iOS Gmail mobile app. In the meantime, if you usually send out multiple emails at once, why not install the GMass mail merge chrome extension?
