Greetings! I have a question regarding this matter. I've observed that prominent websites, like JavaRush, for instance, send out newsletters via email. Therefore, if I possess a database of email addresses, how can I carry out such mailings to these addresses? I would prefer to accomplish this without relying on specific mailing services and incur no costs.

Additionally, it would be ideal if the emails avoid being marked as spam. If anyone has knowledge on this topic, kindly provide me with some guidance.

To send out newsletters to a database of email addresses, you have a few options. However, it's important to note that sending a large number of emails without using a dedicated mailing service can be challenging and may result in emails being marked as spam.

If you still want to proceed without using a mailing service, here are some steps you can follow:

1. Set up an SMTP server: You'll need to install and configure an SMTP server software, such as Postfix or Sendmail, on your server or computer. This will allow you to send emails directly from your own server.

2. Ensure proper DNS configuration: Make sure your server has a valid reverse DNS (PTR) record and that the domain you're sending emails from has valid SPF and DKIM records. These measures help authenticate your emails and reduce the chances of them being flagged as spam.

3. Implement throttling and scheduling: Sending too many emails at once can raise red flags. Implement a mechanism to throttle the rate at which emails are sent, and consider scheduling the email deliveries over a longer period of time.

4. Comply with anti-spam laws: Familiarize yourself with the CAN-SPAM Act (if applicable to your location), which sets rules for commercial email messages. Ensure your emails include an unsubscribe option and comply with other requirements.

5. Monitor deliverability and reputation: Regularly check the deliverability and reputation of your email server and domain by monitoring bounce rates, user complaints, and blacklists. Take corrective actions if needed.

It's important to mention that relying on a specialized mailing service often simplifies these steps and ensures better deliverability rates. These services handle the technicalities for you, manage recipient lists, and provide analytics to improve your email campaigns.

In order to avoid being labeled as a spammer, there are many precautions one must take when sending out emails. However, even with these measures, sending a large number of emails at the beginning is not feasible. It is necessary to gradually increase traffic and "warm up" your IP address in order to establish a good reputation. This is particularly challenging for new mail servers, as major market players like Google and mail.ru tend to be cautious about allowing them to operate.

Additionally, it is important to regularly check spamlists to ensure that your address is not listed. Some networks and hosters frequently visit these lists. It is also necessary to monitor undelivered addresses and remove them from the mailing list permanently or for an extended period of time, as this significantly affects reputation. If the mailer accepts incoming mail, it is crucial to fine-tune the settings, particularly regarding timeouts, graylisting, spam slicing, and blacklisting.

Lastly, it is imperative to never send anything to addresses "found on the Internet." Spam lists intentionally publish "trap addresses" to deter such practices.

In summary, this process is not easy and demands considerable effort. For small email volumes and individuals lacking expertise in this area, it is much simpler and more reliable to utilize ready-made services provided by professionals.

Unless you have fewer addresses, for example 1-2K, the host will not provide more than 10K addresses. Both the host and mailing services must demonstrate that the addresses are obtained with the consent of the end users.

The collection and use of personal data is a critical topic in today's digital age. It is important for companies to ensure that they have proper consent from individuals before sending any communication. This helps maintain the trust and privacy of users.

If you have a database of email addresses and want to send newsletters without relying on specific mailing services or incurring costs, there are a few options you can consider. However, it is important to note that sending mass emails can be complex and time-consuming, and there are risks involved, such as being marked as spam.

One option is to set up your own email server and use it to send the emails. This requires technical knowledge and expertise in managing mail servers, as well as configuring proper email authentication protocols like SPF, DKIM, and DMARC to increase deliverability and reduce the chances of being marked as spam.

Another option is to use open-source email marketing software like PHPList or OpenEMM, which allows you to manage your email campaigns and send newsletters from your own server. These tools often provide features like subscriber management, email templates, and tracking capabilities.

However, it's important to note that maintaining your own email infrastructure requires significant effort and resources, including server maintenance, IP reputation management, and compliance with anti-spam regulations like CAN-SPAM or GDPR.

It's worth considering that using reputable email service providers (ESPs) can be a more reliable and efficient solution for sending newsletters. ESPs have the infrastructure, expertise, and deliverability strategies in place to ensure your emails reach their recipients' inboxes. While many ESPs charge for their services, some offer free tiers or trial periods that might suit your needs.

additional tips to help improve the deliverability of your emails and decrease the chances of them being marked as spam:

1. Build a Permission-Based Email List: Only send emails to individuals who have explicitly given you permission to contact them. Avoid purchasing email lists as they often contain outdated or invalid addresses, which can lead to higher bounce rates and spam complaints.

2. Personalize Your Emails: Tailor your newsletters to make them more relevant and engaging for your subscribers. Include their names in the subject line or body of the email, segment your list based on interests or demographics, and provide valuable and informative content.

3. Optimize Your Email Content: Avoid using excessive capital letters, exclamation marks, or words commonly associated with spam. Use a balanced mix of text and images and ensure your HTML code is clean and error-free. Be cautious with attachments and avoid using too many hyperlinks.

4. Implement Double Opt-In: Consider using a double opt-in process where subscribers confirm their subscription by clicking on a verification link sent to their inbox. This helps ensure that the email addresses are valid and owned by the subscribers.

5. Provide an Unsubscribe Option: Make it easy for recipients to opt-out of your email list by including an unsubscribe link in every email. Honoring these requests promptly helps maintain a good sender reputation.

6. Monitor Your Sender Reputation: Regularly check your sender reputation using tools like SenderScore or GlockApps. Maintain proper email authentication records, monitor bounce rates, and promptly address any issues or complaints.

7. Test and Analyze: Before sending emails to your entire list, test your campaigns by sending them to a small group of recipients. Analyze the results, including open rates, click-through rates, and spam complaints, to optimize your email content and improve performance.


few additional tips for successful email newsletters:

1. Engaging Subject Lines: Craft compelling and concise subject lines that grab the recipient's attention. Avoid using all caps, excessive punctuation, or misleading information, as these tactics can increase the chances of your emails being marked as spam.

2. Mobile-Friendly Emails: Optimize your email design for mobile devices since a significant portion of subscribers access emails on smartphones and tablets. Ensure that your emails are responsive and display correctly on different screen sizes.

3. Consistent Sending Frequency: Establish a consistent sending frequency so that subscribers know when to expect your newsletters. Overly frequent or sporadic emails may increase unsubscribe rates and decrease engagement.

4. Valuable and Relevant Content: Provide valuable and relevant content in your newsletters that aligns with the interests and preferences of your subscribers. Offer exclusive updates, promotions, educational articles, or industry insights to keep them engaged and interested.

5. Clear Call-to-Action (CTA): Include a clear and prominent call-to-action in your emails. This could be a button or hyperlink that leads recipients to your website, a landing page, or any desired action you want them to take.

6. Segment Your Email List: Divide your email list into smaller segments based on demographics, preferences, or past interactions. By tailoring the content to specific groups, you can increase relevancy and engagement, leading to higher open and click-through rates.

7. Test and Analyze: Regularly test different elements in your emails, such as subject lines, content layout, CTAs, and sender names. Analyze the results and make data-driven decisions to optimize future campaigns.

8. Monitor Deliverability Metrics: Keep an eye on key deliverability metrics, like bounce rates, spam complaints, and open rates. Monitoring these metrics will help you identify any issues and take necessary actions to improve email deliverability.

You could script mailings using something like Postfix or Exim, but without proper IP warm-up, DKIM/SPF/DMARC configs, and a good sending reputation, your emails will likely get throttled or flagged as spam.

Free and DIY approaches often lead to blacklists or poor deliverability. Big players like JavaRush rely on specialized ESPs (Email Service Providers) with huge infrastructure and feedback loops to keep inbox placement high
