I am sure you know how annoying spam emails can be. A lot of sites ask for your email address. Once you give them your email address, they keep sending you newsletters. Of course you can unsubscribe or mark these emails as spam. But unsubscribing does not always work. A lot of sites also share your email addresses with their advertisers, who in turn send you spam emails.
Before you set up Akismet on your WordPress blog, you need an Akismet API key. To get an Akismet API key, you need to have a free WordPress.com account. So head on over to the Akismet website and get an Akismet API key. If you already have a WordPress.com account you can sign on using your existing account or you can create a free account.
Once you sign in, you will be presented with an Akismet payment plan. You can select the payment plan that suits you. If you are using this on your personal blog or for non-commercial purposes, and you don’t want to pay anything you can select the donation plan and pull the “amount to donate” slider to zero. Akismet is an amazing service and it will save you a lot of time so if you are using this for a commercial site, you should definitely consider paying for it.
If you manage a WordPress site, you definitely know about comment spam. Users leave all sorts of comments on your WordPress site and sometimes it can be quite an ordeal to manage the comments. Akismet is a plugin which comes bundled with WordPress. It is a service from the makers of WordPress which uses a special algorithm to identify spam comments.

Once you have set up Akismet, it will start filtering your comments for spam. If you have a lot of spam it might be tempting to ask Akismet to delete the spam, but we find it hard to trust a software too much, so we like to put spam comments through a further test.
