Gmail enforces a strict maximum email message size of 102 KB.
This refers to the raw HTML code that makes up your email, and a lot can be done within this restriction. However, for particularly long emails, this means that some parts of your message may not be displayed in Gmail.
For instance, this sentence would consume 590 bytes of data if it were being displayed in HTML in an email. That's almost a half of 1 kilobyte of the 102 KB maximum before clipping occurs.
When your message is clipped, your readers who open it in Gmail will see a link to load the entire email that looks like this:
This is a challenge because the Staffbase Email tracking pixel is attached to the bottom of each outgoing email. This prevents the email from being tracked unless the reader chooses the above option to view the entire message. It may not be clear to the reader that they are not seeing the entire email as intended.
Tips To Prevent Your Email From Being Clipped in Gmail
- Send a test email to your Gmail account and look for the above warning that the email is being clipped.
- Use link shortening services to keep your overall email size small. Long links contribute heavily to overall email sizes.
In the Email Designer, try to limit the number of blocks included in your design. Each block itself is approximately 1-2 KB and each block can hold up to eight elements which will also contribute to the overall size of the draft.
Because Staffbase Email hosts the images that are added to Email Drafts and Templates, the sizes of image files do not change the size of your email message.
Only the HTML used to display these images from the hosted location uses up part of your available size limit.
- When you create a draft using Email Designer 3.0, we include a Gmail Truncation warning that will indicate the current size of the email, so keep an eye out for this!
It is a priority for Staffbase Email to keep the HTML it uses in email designs as data-light as possible. This is a limitation imposed on every Gmail user regardless of circumstance and only Google would be able to change it.
