Have you ever hit send on a newsletter only to realize a link was wrong? Most email service providers will say it’s impossible to change a link in an email after sending — but with the right tools, it can be done. In this guide, you’ll learn exactly how to quickly fix incorrect or outdated URLs in your email campaign without sending an awkward follow-up.
Wrong link in email campaign – what now?
Imagine this: you’ve just sent out a newsletter to your subscribers and realized one or more of the links is incorrect. When you spot a wrong link in an email campaign, it can feel like a disaster. At first glance, it seems like you only have two options:
A) Panic and hope no one notices
B) Send out an awkward apology email correcting your mistake

Luckily, there’s a better solution. With Mail Designer Delivery Hub, you get a third option: use Mail Designer Link Rescue to change a link in an email after sending. This feature allows you to quickly fix incorrect URLs in your newsletter and make sure every subscriber sees the right content.
