If you suspect that your email marketing infrastructure is under a DDoS attack, follow these steps:
1. Contact Your ESP Immediately notify your Email Service Provider. They may already have mechanisms in place to mitigate the attack and can take further action to protect your services.
2. Activate Emergency Plans Activate any emergency response plans you have in place for dealing with DDoS attacks. This might include switching to backup servers or pausing non-critical services.
3. Communicate with Stakeholders Inform your stakeholders, including customers, about the situation. Transparency can help maintain trust and manage expectations during the downtime.
