Monitoring Amazon SES Complaint Rates with CloudWatch Alarms and Real-Time Slack Notifications

Amazon Simple Email Service (SES) is a powerful tool for sending high volumes of emails quickly and efficiently. However, to maintain your email-sending capabilities and ensure high deliverability, it's essential to monitor your sender's reputation closely. One key metric for assessing this reputation is the Complaint Rate, which measures how often recipients mark your emails as spam. A high complaint rate can lead to your emails being filtered into spam folders, throttling, or even [...]

Methods in Evaluating Foundation Model Performance

A foundation model is a large-scale, pre-trained artificial intelligence model that serves as a general-purpose system for various downstream tasks. These models, such as GPT for natural language processing or CLIP for vision-language understanding, are trained on extensive datasets and can be fine-tuned or adapted to specific applications. Foundation models are characterized by their ability to generalize across tasks, making them highly versatile and impactful in AI-driven solutions. Evaluating these models' performance is essential to [...]
