Warming Up Servers for 100% Inbox Delivery 📬🔥

Hey there! ✌️ There are plenty of articles out there on "Why warming up is needed" and "How to warm up SMTP servers properly," so I won’t go deep into the details here. To put it simply: warming up SMTP servers means gradually increasing the volume of sent emails to improve the reputation of your IP address and domain. This helps you avoid blocks and spam filters.

But warming up isn’t just about the start—it’s an ongoing process. Essentially, it's about working on your email performance statistics over time.

If you're sending email campaigns to your target audience but experience a high rate of complaints or a significant number of emails being deleted without being read, that’s a clear sign your audience doesn’t expect or welcome your emails. Email providers react negatively to such metrics. And it doesn’t matter how you send your emails—whether through your own SMTP servers or services like DashaMail, SendPulse, etc.

Sending emails to accounts you own and processing them helps reduce complaints and increase open rates at a minimum. This can significantly improve your sender reputation.

In Summary

Email warming 🔥 (sending and reading emails from your own accounts) is essential for:

1. Increasing the daily sending limit.
2. Improving campaign statistics (boosting open rates and reducing complaints).

If you're sending emails to an audience that isn’t quite your target audience (or worse, to "cold" lists), poor performance metrics are unavoidable in 99% of cases. If your offer doesn’t resonate with your audience, deliverability problems are inevitable. Your SMTP servers will keep getting blocked regularly, and email providers will start treating your mail as spam.

‼️ In such conditions, warming up becomes not just a useful tool but a necessary one. It helps smooth out negative metrics (like low open rates and high complaints) and creates a perception of engagement from "subscribers." However, it’s critical to understand: warming up is not a magic bullet. If your offer isn’t relevant to your audience, even the most high-quality warm-up won’t save you. In the long run, you need to work on building a better email list and ensuring your campaigns are relevant. Otherwise, it’ll all turn into an endless struggle with blocks and falling reputation. 🔥

Let’s Do Some Math

So, you understand what warming up is and why it’s necessary. Let’s calculate the resources required to warm up a single server (domain) for sending 10,000 emails daily.

Here’s what you’ll need:

1. 10,000 accounts (some accounts may be invalid!).
2. Mobile proxies (~2,500 rubles per proxy).
3. Specialized warming-up software (~5,000 rubles).

Here’s the breakdown:

• 10,000 accounts = ~10,000 rubles.
• 1 mobile proxy = ~2,500 rubles.
• Warming-up software = ~5,000 rubles.

Total: approximately 15,000 rubles to warm up a server capable of sending 10,000 emails daily. Now let me tell you how our service can not only eliminate the manual, time-consuming tasks but also cut these costs by 50%. 🤑💡

WarmCloud - Cloud-Based SMTP Server Warming

A few months ago, we launched this unique service to help warm up new servers and/or influence the performance of your existing email campaigns. It doesn’t matter whether you’re sending emails via your own SMTP servers or 3rd-party email marketing platforms.

What makes our service unique is that you no longer need to buy accounts, proxies, or software—or overload your computer! The era of "trustmasters" and "inboxers" is over!

And let’s not forget cost efficiency—this is the very factor that reduces your warming-up expenses by half! You’ll pay just 10 kopecks per email address received from our service.

How Does It All Work? 🤓

There are several ways to interact with our platform:

1. API

Go to the relevant section in our Telegram bot @warmcloud_bot, where you’ll find three methods:

• The first method retrieves an available email address.
• The second method lets you transmit the email subject to be read.
• The third method leaves an email unread to avoid 100% read-through rates. It’s all very simple!

2. Mailing Template for ZennoPoster

Specify your SMTP server and email content, and the mailing template will handle everything for you. This template is a complete solution for sending emails because it includes all the necessary features, such as:

• Mixing in your own email list.
• Macros.
• Tracking opens, complaints, clicks, and more.

A detailed guide is available in the "Integrations" section of our bot.

3. Plugins for ZennoPoster

This option, like the API, is more useful for developers who want to integrate it into their custom templates. And don’t forget about our generous referral program!

Across all three interaction methods, the primary principle remains the same:

• When sending out your emails, a request is sent to our service, which provides you with a trusted email address (we have many).
• You send an email to this address, and after that, in approximately ~20% of cases, we read the email and mark it as trusted.
