    Good afternoon. I conducted a basic assessment of your project, but I lack information to calculate the budget. I have a few questions; we can discuss via text, but it's better to have a call (if convenient, I will create an audio meeting through Hangouts in Google Meet).
    About me: What sets me apart from competitors?
    I am a programmer, IT solutions architect, with 12 years in IT. I founded the company ingello\systems, previously the technical director of TAXER. Before that, I was the director of Sitio. Prior to that, I was a senior programmer at Igrolan.
    During my career, I have saved startups and companies (without exaggeration) hundreds of thousands of dollars. There are specific examples, see below.
    I am looking for interesting and complex, multi-stage projects; I also consider equity participation in startups (I have experience). You can trust me with a project of any level, and here is the proof:
    Video about my team:

    Our website:
    https://systems.ingello.com
    Here are some interesting projects I have worked on:
    Garage — for this startup, we saved at least $40,000 (!!!) on the development of mobile and administrative applications.

    Taxer — this was a previously funded product that became profitable, used by hundreds of thousands of Ukrainians. I collaborated in the role of Technical Director (CTO).

    And here we, on the contrary, lost several thousand dollars due to an architectural mistake. But then we rehabilitated. This is a very complex project for a TOP-1 Amazon partner, a cool German brand.

    Mobile applications and admin panels for a taxi and delivery service. Here you can see a bit of the working process.

    Among our cases, you can find those that are similar to your project — some infrastructurally, some architecturally, some functionally. Here are a few links.

    In response to your request for creating a system for automated email campaigns of large volume (3+ million emails per day), I have prepared a detailed proposal.

    To implement such a large-scale task, I suggest using the most reliable and cost-effective solution on the market — Amazon Simple Email Service (SES). This service allows sending large volumes of emails with maximum deliverability but requires professional setup and a strategic approach to launch. The price may be around 250,000 UAH.

    Attention!
    If I indicated "1111" or "777" in the total bid, it means I need more information to assess the project (also deadlines may vary depending on the scope).

    I will create a high-volume email system on Django with Celery for processing 3M+ messages daily. I will connect integration with your CRM via API and set up a distributed infrastructure with load balancing for sending. I will add a monitoring system for bounce rates and deliverability for optimization.

    Задача, безусловно, интересная. Однако для обеспечения ~35 писем в секунду потребуется кластер.
    Основная проблема заключается не в самом кластере, а в том, что при таком графике отправки ваша система будет заблокирована в течение часа. Письма даже не будут попадать в спам, особенно если использовать «холодные» IP-адреса.

    Для достижения цели необходимо применять специализированные сервисы рассылки, такие как Amazon SES или SendGrid, которые обеспечивают доставку сообщений получателям.
    Стоимость указанного вами объёма отправки составит порядка 9 740 $ в месяц только за услуги Amazon.

    Теперь рассмотрим вопрос стоимости настройки сервиса, который сможет стабильно отправлять почту в таких объёмах. Очевидно, что эта сумма никак не может составлять 27 000 грн.

    Если кто-то утверждает, что подобную систему можно построить на локальном почтовом сервере или даже на кластере локальных серверов, то это, к сожалению, будет лишь напрасной тратой времени и ресурсов.
