How Does High Traffic Affect Email Deliverability?
High traffic loads can severely impact email deliverability. When the server is overwhelmed, emails may be delayed or even go undelivered. This not only affects the success of your campaign but also harms your sender reputation. Internet Service Providers (ISPs) monitor the consistency and reliability of email senders. Frequent delays or failures can lead to your emails being marked as spam or, worse, your domain being blacklisted.
