    Technologies: Node.js, JavaScript, Nodemailer, Handlebars, SMTP

    - Intelligent increase of sending volumes with flexible settings
    - Combined restriction logic (daily and overall limits)

    Features: The system analyzes the necessary number of addresses for warming up, automatically adjusts the sending plan when limits are reached, and supports different sending modes (fixed, random, rotational).
    Results: Reduced warming time by 70%, increased inbox delivery rate from 35% to 95%, eliminated manual labor and human errors. The system successfully warmed up more than 10 commercial domains with varying sending volumes — from small transactional services to marketing platforms.
    Scalability: Supports various warming strategies (standard, aggressive, conservative) and easily adapts to the needs of any business.
