Sending emails from Gmail: How to fix sending problems

Email is increasingly gaining prominence in our lives. With the reduction of postal mail for ecological reasons, and due to the great advantage that its immediacy offers us, it makes it ideal for both our work and private lives. Sometimes, especially if we have to send an important email, sometimes we find ourselves in a very frustrating situation if it does not arrive in the end. Then we receive an error message making us unable to send our e-mail at that moment. In these situations, the culprit may have to do with us, or it may also be the mail server. In this tutorial we will see how to solve problems when sending emails from Gmail when a failure occurs and our email does not reach its destination.

Sending emails from Gmail

I send emails and they don’t arrive, who can be the culprit?

At the time we send an email, for the sending to be successful, three actors have to intervene:

  • Our computer or other type of equipment.
  • The Internet connection represented by our router, and other additional equipment that we may have, such as, for example, Wi-Fi repeaters.
  • The email server.

On rare occasions it can happen that the fault of the failure lies with the mail server itself. However, the most common is that it is an error on our part, and later we will explain how to solve most of them, so that you can send emails from Gmail without problems.

For example, email clients like Gmail typically have 99.9% availability throughout the year. This means that it is very rare for your mail servers to go out of service. Therefore, the most common thing is to think that our problem that prevents us from connecting to the server or communicating correctly with it has its origin in our computer or in our Internet connection.

Everything you need to review to fix the problem

Taking into account that it is very unlikely that the culprit of not being able to send an email is Gmail, we are going to give you a list of points that you should check that they are working correctly, because if we cannot send emails it is very likely that we are the ones guilty.

Check that your Internet connection is working properly

If we have sporadic cuts in our Internet connection, they can cause that when sending emails from Gmail they do not reach their recipients correctly. For example, if we are far from the router connected by Wi-Fi we can have problems because the signal does not reach us well. In those cases, it would be advisable to use the 2.4 GHz band that better supports distance, and also, you gain in stability. Another option would be to connect to the 5 GHz Wi-Fi band being closer to the router and thus make sure you do not have problems.

It is very important that, if we are going to send emails with many large attachments, we have a very good Internet connection, and also a good WiFi coverage or connect our PC via cable, in order for these documents to be uploaded to the Internet quickly.

We can try to restart the router so that, in case the failure is with the connection itself, it can be fixed. On the other hand, if we have another computer that we have at home, we can try to check if the problem continues to happen or only happens on that computer.

You could also do a speed test to our connection and check that our upload, download and ping speeds are the usual ones. Another thing that can be tried is to visit well-known websites that usually load fast, and see if it loads quickly or there is a problem. If in this aspect we detect failures, the problem will be in a specific fall of your Internet operator, that we have a faulty router, or that the Ethernet network cable is in bad condition, which happens rarely.

Things to keep in mind about Gmail that you might not know

In case you didn’t know, Google limits the number of messages that users can send each day and also the number of recipients per message. These measures are taken by Gmail in order to avoid Spam and protect our email accounts. If you have sent too much emails, or you have an automated system for sending emails almost massively, you may find yourself with just these limits.

Therefore, when you send emails from Gmail, they may end up being returned or rejected, especially if you send a lot. Another option would be for them to go to the Spam tray and not see them. Gmail’s current limit is 500 messages a day and if you exceed it, you will receive a message like “Google has reached the sending limit “. All the limits that Gmail establishes in sending messages can be consulted here.

The browser as the source of the problem

Most of the time, the culprit that our email does not work properly is our web browser. One of the things that we should test first is to see if it works well with another browser. In principle, we could start by using those that are installed as standard in Windows and that we may not be using, such as Microsoft Edge or Google Chrome. If necessary, we could consider installing a new one that we do not have installed like Chrome, Firefox or Opera.

If it works well with other browsers and the problem continues, what we should try is to find out the reason why our browser is giving problems. So we start by clearing cached temporary files and cookies. In addition, we will also proceed to disable all the browser extensions that we have installed to prevent any of them from causing problems.

As for clearing the cache and cookies, it is usually done through its ” Settings ” or ” Settings ” section. It is usually accessed from a main options menu located in the upper right corner. Then there is usually a search engine in which we could write ” Cache / History / Clear browsing data ” to take us directly. Also in the section that is usually called ” Privacy and Security ” we could find it, this would be an example with Google Chrome:

On the other hand, another thing that we could try is to restore the factory settings of the browser so that it remains with the options that came by default.

Other solutions to resend emails with Gmail normally

If after trying to try all these things we still cannot send emails from Gmail from our browser, then the failure may be something more hidden. At this point, we must check that the time and date of our equipment are correct . And although it may seem like a minor failure, they can be the cause of quite a few problems.

Also, we could change the DNS of our computer or router to Google’s ( – or Cloudflare’s DNS ( – This would be an example editing the TCP / IP version 4 of Windows:

As you have seen, we have several solutions to send emails from Gmail again normally, it is very important to follow all the recommendations step by step to find the problem, and then solve it.
