I have just figured out how to fix it and it's working! This is how i fixed it: Before moving to the SendGrid SMTP Server, I had already sending emails working but the difference is that it wasn't with my website's domain, It was with another domain I had so I moved to SendGrid. However, I have figured out that in Site Settings > Basic (In the Administrator panel) that my old domain that I was previously sending from was still in the Site Notification Email field so I changed it to my new emailing address

I also didn't received any email from you.

is this the key you received from SendGrid?

and at least provide the other parts

@~Z~ I asked you where to provide them because of course the API Key (the password in my case) needs to be secret and I can't provide them here.

What a question. You've got problems. I was just trying to asure you entered the right stuff.

@~Z~ Where can i provide them?

Please provide the credentials you are connecting with in the Ossn SMTP component

oh also i forgot i found this too about SMTP https://docs.sendgrid.com/for-developers/sending-email/getting-started-smtp#what-is-smtp

@Arsalan The password itself is the api key that i said, look at this link from Sendgrid https://docs.sendgrid.com/for-developers/sending-email/integrating-with-the-smtp-api This is the only thing i found for sending emails using SMTP

I tried SMTP on smtp.com and it worked fine for me. I don't think you need to specify api key , SMTP need server name, username, password, port. Can you share details at [email protected] If you want I can try to debug
