Mail sent through SQL Server Express - Mail (Id: 17) queued - sql-server

Question

I followed a guide online, to send a mail through SQL Server Express, but it keeps saying "Mail (Id: 1) queued.", and up to 17, as I have tried 17 times now.
The email is a dummy mail, and not my real one. It is just an example. I use my real mail in the SQL Server Management Studio. SQL Server Express as my teacher called it.
First part of code (To create sysmail account)
EXECUTE msdb.dbo.sysmail_add_account_sp
#account_name = 'MailTest',
#description = 'Sent Mail using MSDB',
#email_address = 'testmail#mail.com',
#display_name = 'Landlyst',
#username='testmail#mail.com',
#password='password',
#mailserver_name = 'mail.google.com'
Second part of code (To create Database Profile)
EXECUTE msdb.dbo.sysmail_add_profile_sp
#profile_name = 'MailTest',
#description = 'Profile used to send mail'
Third part of code (To add database Mail account to profile)
EXECUTE msdb.dbo.sysmail_add_profileaccount_sp
#profile_name = 'MailTest',
#account_name = 'MailTest',
#sequence_number = 1
Fourth part of code (Grants permission to all)
EXECUTE msdb.dbo.sysmail_add_principalprofile_sp
#profile_name = 'MailTest',
#principal_name = 'public',
#is_default = 1 ;
Fifth part of code (to enable the program to send mail, and not give an error)
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Database Mail XPs', 1;
GO
RECONFIGURE
GO
Sixth part of code (To send the test mail)
EXEC msdb.dbo.sp_send_dbmail
#profile_name = 'MailTest',
#recipients = 'receiver#queryingsql.com',
#subject = 'Mail Test',
#body = 'Mail Sent Successfully',
#body_format = 'text'
I am not very good at SQL, but I need this to work as a trigger on a user.
Could someone please help me with this?

I ran all the same commands you did (with the profile name of 'admin') and my msdb.dbo.sysmail_log table was still empty. I additionally followed step 5 in this link which suggests running the command below (back up the registry first). I did a search in the registry to find where UseDatabaseMail and DatabaseMailProfile were. However, the command did not work, so I changed the values manually in the registry.
USE msdb
GO
EXEC master.dbo.xp_instance_regwrite
N'HKEY_LOCAL_MACHINE',
N'SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL13.SQLEXPRESS\SQLServerAgent',
N'UseDatabaseMail',
N'REG_DWORD', 1
EXEC master.dbo.xp_instance_regwrite
N'HKEY_LOCAL_MACHINE',
N'SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL13.SQLEXPRESS\SQLServerAgent',
N'DatabaseMailProfile',
N'REG_SZ',
N'admin'
However, this also did send my queued mail. This link suggested trying to run the Databasemail.exe directly. I searched for 'databasemail' which was in 'C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\Binn'. and ran as administrator. I got the error, "The following feature couldn't be installed: .NET Framework 3.5 (includes .NET 2.0 and 3.0)"
Once .NET 3.5 was successfully installed, my queued mail was sent!
