If you just want to give SendGrid a try, there’s a free plan that includes most of the primary features. However, this plan is a bit limited when it comes to the sending allowance of 100 emails per day. The next tier pro plan is $14.95 per month, plus $10 per for every 10,000 contacts you maintain. On the far end of the spectrum there are also enterprise plans available (if you’re looking for those, you can also check out Mailjet).
