It's possible that you have landed on an ISP blocklist if you're seeing a large number of soft bounces (anything over 5-10%) over an extended period of time,
Do not panic. Deliverability issues are (unfortunately) a normal part of the email marketing industry. You will not be blocked forever. The most common blocking issues are due to list management issues. WordFly support can help troubleshoot what's going on.

Here's where you come in. If you've landed on a blocklist there are generally four places to start looking for the solution:
|List management||99% of the time this is the culprit. Make sure you are removing hard bounces, unsubscribes and abuse complaints right away (WordFly does this for you). Do not send to hard bounces more than 2 times. You must maintain a clean list if you want to avoid blocking issues.|
|Infrastructure||Do you have DKIM setup correctly for your sending domain? ISPs require this important TXT record on your domain to authenticate your mail.|
|Sending Volume||Are you sending 50 emails one day and 2 million the next? ISPs don't like inconsistent sending volumes. Also, it is extremely important to warm up your sending when you're a new sender or when you have switched email service providers.|
|Email Content||This isn't usually a problem nowadays but some content can still cause issues. Stay away from using shortened URLs, invalid URLs, or sending one large image.|
