I registered a user with my email address, use lost password form to send me a password reset link in email, send a test email from your SMTP plugin to my email but i still did not receive a single email.

Can you please recheck you website is sending email correctly? Let me know.

It seems your sendgrid ip is blacklisted by spamcop.
Can i temporarily deactivate your SMTP plugin and install a custom plugin which will log every email in your server instead of actually send email?

Sorry, by mistake i have uploaded wrong version. Please remove shamim-email-log plugin by ftp

Please use ftp/file manager then go to your website wp-content/plugins directory and remove shamim-email-log folder.

If you find any difficulty you can give me FTP access.

I logged email and see that email sent.
Now i re-activate SMTP plugin. Can you please check sendgrid log to see if any email there.

Yes.
Please use any other Mailer in your SMTP plugin setup. If possible use your server SMTP setup.
I see you have “From Email” setup as same domain email. Use this email details to send email.
