You don’t have to learn the codes. But it can be very helpful if you search for them when you face the challenge. Especially if you want to get the most out of your email list by reducing your email bounce rate.
For example, if your email bounce rate is high (hard or/and soft), you can:

• correct emails with syntax errors
• fix typos
• send again to contacts who couldn’t receive it thanks to a technical issue
• realize if an email provider blacklisted you
• and more.

But you have to know the bounce codes in order to solve these difficulties. Therefore we collected them for you.
