Files

You may upload up to 200 MB files to your SmartSender Library. Files can be uploaded from your computer or added by file URL.

But before you upload your images, make sure they’re optimized for best results and to reduce the likelihood of an upload error.

Get your image ready to upload to your Library by making sure it has the right height and width, resolution, file size, and file type.

	Height	Width
Header Image	Less than 200 pixels will fully display in email preview panes.	600 pixels Smaller widths will stretch your image to fit the header and larger widths will stretch your email header and distort your email.
One-column Template	*See note below	600 pixels or less
Two-column Template	*See note below	250 pixels or less
Three-column Template	*See note below	150 pixels or less
Event Landing Page	150 pixels is recommended	800 pixels is recommended
Event Registration Page	150 pixels is recommended	800 pixels is recommended

Type	Works Best With	Pros	Cons
PNG	All Images	Best quality, regardless of content Supports full transparency Great for text Can fix some distortions caused by other file types Doesn’t compress when uploaded	Larger file size
JPG	Photos	Small File Size	Distorts image to reduce file size Doesn’t work well with text Doesn’t support transparency Compresses when uploaded
GIF	Logos Simple Graphics Low Resolution Images	Small file size Supports basic transparency Doesn’t compress when uploaded	Limited to 256 colors Images can appear grainy if they use web-unsafe colors

Tip: If an image won’t upload as a JPG file, try saving it as a PNG or GIF file.
