Another option is to set up a Filter system on your email client - how you do it depends on the client, but generally you can filter on the "sender" as all emails from SRP contain a similar character string in the "sender" address. Create a folder just for SRP emails and tell the filtering software to send it there.

This is what I do, and it keeps forum emails away from the inbox (and presumably the important mail) whilst giving you the opportunity to peruse replies to threads you have subscribed to at your leisure.

Of course, you can just turn off the emails as has been mentioned.But filtering them away from the inbox works well for me.
