I'm planning on receiving email/forwarding email using postfix, but sending email using sendgrid.

According to this tutorial, I need an MX record pointing to my machine - http://www.andreagrandi.it/2014/08/31/getting-started-with-digital-ocean-vps-configuring-dns-and-postfix-for-email-forwarding/

I've already set up sendgrid, and its working -> i sent a test email from ibrahim@mysubdomain.domain.com. I did this with no change to my DNS.

My question is, when I set up the MX for email forwarding, will sendgrid stop working?

From what I'm reading, I need an MX record saying sendgrid is a valid sender. But today, sendgrid is able to send, without me doing any DNS change.

I would "just try it" but its my first time with email, and the blacklists make me paranoid.

I've read other answers on mail setup, but I haven't seen one with a different setup for sending and receiving.

No, it doesn't need to. Instead of MX record, you need SPF.

I found an answer from stackoverflow.

First and foremost, the MX records for your domain are used only to specify the hostnames of the servers to handle INCOMING mail for your domain - i.e. the MX records have nothing to do with the servers that are used to send outgoing mail
