[SendGrid](https://sendgrid.com/) is one of the well-known email service providers, and it can be integrated easily with HollaEx Kit. In this article, we will go through step by step on how to set up SendGrid with HollaEx Kit.

The first thing you should do after signing up is create a new sender. Go to the 'Sender Authentication' section in the sidebar and continue.

Now, you should make an API key for SendGrid. Go to the 'API Keys' section in the sidebar and create an API key. You should give at least '**Mail**' **permission** to it! 

Don't forget to keep it somewhere once it's generated.
