No, it shouldn’t matter that your website has a typo.
It certainly shouldn’t matter that your latest newsletter uses an apostrophe incorrectly.
It shouldn’t matter, but it does matter!

It’s heartbreaking to lose sales because of a typo or misplaced apostrophe. Thankfully, it’s totally avoidable with just a little extra attention to detail.
