There are several ways to fix this error, and here are three commonly used methods. So join us to fix this error, or if you encounter this error in the future, you can quickly fix it.
Now we want to see how to fix this error. Step by step, do the following:
Change your Gmail password to numbers
The first way we suggest you is to change your password. So first, it is better to change your Gmail password. When changing the password, use numbers to minimize the error when entering the password in the newsletter plugin.
Also, keep in mind that passwords are critical, and you need to be very careful when encrypting your Gmail that hackers can not access your Gmail. Here you have to use a simple password to resolve the error.
Disable Gmail 2-Step Login
Log in to Gmail with which you want to send newsletter emails and provide information to the system. Click on your avatar icon at the top right of the Gmail panel. Then click My Account.
Then click Sign In and Security.
Now find the 2 Step Verification option and click on it. Finally, click the Turn Off button to disable the two-step Gmail account login.
A two-step login of a Gmail account is an excellent and practical method that makes user accounts more secure. Google does this for its users to protect Google accounts. But here, it is better to do this to reduce the possibility of error.
Open access to low-security Gmail applications and sites
The third way we suggest you fix this error is to leave low-security apps and sites accessing your account. It would help if you did this to improve your mistake. Log in to your email again to do this. (This means the email you want to use in the Newsletter plugin.)
Now go to the settings page for low-security software.
And activate the button for this setting to turn blue.
Now your Newsletter plugin can send your emails without any problem.
But using these methods may not solve your problem. In this case, you need to contact your hosting provider. So if the emails are still not sent, ask your host to open ports 465 and 25 of your web server.
We hope you have been able to fix this error easily using this tutorial.
Be triumphant and victorious.
