  • eM Client is one of the most popular email clients. Despite the great features that eM Client offers to its users, some of them reported that eM Client is not sending emails. This can be a big issue, and in today’s article, we’ll show you how you can fix this problem on your own.

    eM Client is a great application, but sometimes issues with it can appear. Some common problems reported by users are the following:

    How do I fix eM Client not sending emails?

  • Use a different email client
  • Check your email configuration
  • Check your antivirus
  • Enable Use SSL/TLS if available 
  • Change NOD32 settings
  • Reinstall eM Client
  • Perform a Clean boot
  • 1. Use a different email client

    If eM Client still isn’t receiving emails, you might want to try using a different email client.  There are some other just as reliable email clients with built-in productivity features that may not cause as many issues as eM Client.

    Most worthwhile email clients on the market allow you to log in to an unlimited number of email accounts and easily access them from one main window.

    There are some good replacements for this app that include similar contact management features that will allow you to sync all contacts from all your email accounts in one centralized platform.

    You will be happy to find that these tools include email templates, signatures, translation, and spellchecker features, as well as integrations of popular productivity apps and social media.

    2. Check your email configuration

    According to users, eM Client might not be sending emails if your email configuration isn’t correct. Apparently, this issue occurs with Gmail as well, but you can fix it just by changing a couple of settings.

    To fix this issue, you can try changing the port for the SMTP server to 465 with SSL. If that doesn’t work, you can try using port 587 (with TLS) or port 25 (with SSL). After making these changes, check if the eM Client is working properly.

    We have to mention once again that this solution applies only to Gmail. If you’re using a different email provider, you’ll probably have to use different values.

    3. Check your antivirus

    Having a good antivirus is crucial if you want to protect your system from online threats. However, sometimes your antivirus can interfere with eM Client and cause it to stop sending emails. To fix the issue, be sure that eM Client isn’t blocked in your antivirus.

    If the application isn’t blocked, try disabling certain antivirus features, such as the firewall, and check if that helps. In some cases, you might have to disable your antivirus altogether. If disabling the antivirus doesn’t work, your next step would be to uninstall your antivirus.

    Several users reported issues with Kaspersky, but after removing it, the problem was resolved. This issue isn’t limited only to Kaspersky, and other antivirus tools can also cause this problem, so even if you don’t use Kaspersky, you should temporarily uninstall your antivirus.

    Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

    If removing the antivirus fixes the issue, you should consider switching to a different antivirus solution. There are many great antivirus tools on the market, but if you want maximum protection that won’t interfere with your software, we recommend you try Bitdefender.

    4. Enable Use SSL/TLS if available

    If eM Client isn’t sending emails, the most likely cause for that issue is your configuration. As we already mentioned in the second solution, it’s crucial that you use the correct port.

    In addition to using the correct port, several users reported that they changed their security policy from Use SSL/TLS on special port (legacy) to Use SSL/TLS if available. After making this change, the problem should be resolved and everything will start working again.

    5. Change NOD32 settings

    Users reported issues with NOD32 and its IMAP checking feature. It seems that this feature was interfering with eM Client, and in order to fix it, you need to disable it.

    To do that, follow these steps:

  • In NOD32 go to Advanced setup > Web and email.
  • Now choose Email client protection > IMAP, IMAPS.
  • Now uncheck Enable IMAP checking option.
  • Save changes after disabling this option and check if the issue is resolved.

    6. Reinstall eM Client

    In some instances, the issue might occur if your eM Client installation is damaged. If eM client isn’t sending emails, it’s possible that its installation is corrupted. However, you can fix that simply by reinstalling eM Client.

    There are several ways to do that, but the most effective method is to use uninstaller software.

    If you’re not familiar, uninstaller software is a special application that can remove any program from your PC. In addition to removing the desired application, it will also remove all files and registry entries associated with that application.

    Once you remove the eM Client, install the latest version and check if that solves your problem.

    7. Perform a clean boot

  • Press Windows Key + R to open the Run dialog. Enter msconfig and press Enter or click OK.

  • In the window that opens, go to the Services tab, check Hide all Microsoft services and click the Disable all button.

  • Now go to the Startup tab and click Open Task Manager.

  • Right-click the first entry on the list and choose Disable from the menu.

  • Navigate to the System Configuration window.
  • Now click Apply and OK to save changes and restart your PC.

  • Once your PC restarts, check if the problem is still there. If not, enable the disabled applications one by one until you find the cause of the problem. Once you find the problematic application, remove it or keep it disabled and the issue should be resolved.

    Sometimes third-party applications can interfere with other programs on your PC, and the same goes for eM Client. It’s possible that a third-party application is interfering with it, and that is causing the issue to appear. This is why we recommend this solution.
