Imagine: you or one of your subscribers notice that your email has an error in it. Bummer. But it’s up to you to determine if sending a correction email is worth the effort. As every situation is unique, we would only recommend sending a correction when your email:

• seriously misinforms its recipients;
• does not allow recipients to complete a form, do a transaction, get access, etc. ; 
• could damage your brand image, reputation, customer relationships, …

Typos, grammatical mistakes, incorrect images or images that don’t load, are probably not serious enough to require a correction email. You may consider including a correction in the next campaign or issue - but only if appropriate.
