https://myaccount.google.com/lesssecureapps open and host=smtp.gmail.com

updated as but the error persists...

Enabling access for "less secure apps" means that the client/app doesn't use OAuth 2.0 . OAuth 2.0 is the industry-standard protocol for authorization. When you sign in with OAuth 2.0, you sign in to Google's system directly. In OAuth 2.0 , you authenticate directly to Gmail with your credentials and authorize an app to do certain things. The third-party app only sees an authorization token provided by Google as proof that you authenticated correctly and agreed to authorize that app.

Here's a quick example of a demo that produces an email sent from a gmail account (specifically). Note that to send an email through your gmail account you have to turn off the app security which greatly reduces the security of your gmail account. One solution to this problem is creating a new gmail account for the sole purpose of sending emails from this script.

To turn off app security, sign into gmail and access this link: https://myaccount.google.com/lesssecureapps

[Update] See comments below regarding common problems with antivirus software and firewalls that might prevent the email from being sent.

% User input
source = '[e-mail]';              %from address (gmail)
destination = '[e-mail]';              %to address (any mail service)
myEmailPassword = 'sifre123';                  %the password to the 'from' account
subj = 'This is the subject line of the email';  % subject line
msg = 'This is the main body of the email.';     % main body of email.

%set up SMTP service for Gmail
setpref('Internet','E_mail',source);
setpref('Internet','SMTP_Server','smtp.gmail.com');
setpref('Internet','SMTP_Username',source);
setpref('Internet','SMTP_Password',myEmailPassword);

% Gmail server.
props = java.lang.System.getProperties;
props.setProperty('mail.smtp.auth','true');
props.setProperty('mail.smtp.socketFactory.class', 'javax.net.ssl.SSLSocketFactory');
props.setProperty('mail.smtp.socketFactory.port','465');

% Send the email
sendmail(destination,subj,msg);

% [Optional] Remove the preferences (for privacy reasons)
setpref('Internet','E_mail','');
setpref('Internet','SMTP_Server','''');
setpref('Internet','SMTP_Username','');
setpref('Internet','SMTP_Password','');

I tried still giving the same error (https://www.mathworks.com/matlabcentral/answers/433031-sending-e-mail-error#answer_349841)

I looked into the "sun.security.provider.certpath.SunCertPathBuilderException" portion of your error.

These users solved this by disabling the antivirus software: https://www.mathworks.com/matlabcentral/answers/80552-sendmail-error-error-using-sendmail-at-168#answer_90559

...or the firewall https://www.mathworks.com/matlabcentral/answers/258701-receiving-an-error-whilst-attempting-to-use-sendmail#answer_202062
