"into an email attachments" doesn't agree on number--it should be "into an email attachment" (singular) or "into email attachments" (plural).
It's not 100% clear that by "shrink" you mean "reduce file size" rather than "visually scale the image".
"Batch image resizer which will make photos smaller enough to fit them all into email attachments. In three easy steps."
Don't use the comparative form of the adjective "small". "Which" is not needed here either.
"Batch Image Shrinker reduces the file size of a group of images in three easy steps:"
That's a start at least. I hope that helps a bit.
