We have been testing SendGrid’s (https://sendgrid.com ) free service, which allows you to send up to 100 mails per day.

SendGrid

Create an account and log into it.
Click on Settings in the sidebar.
Click on API Keys press the Create API Key button in the upper right corner.
Enter the API Key Name and select Full Access for the API Key Permissions. Press the Create & View button afterwards.
The API Key has now been generated and is shown in the grey area. Copy and save it for later use, as it cannot be retrieved again later on.
In the sidebar, click on Sender Authentication and make sure your account is verified.
