Sending emails from a client side only app is not straight forward, so I'm opening up a service that allows you to easily send transactional emails, such as a welcome email or other action generated email, to users from your mobile app - without requiring a server side.All that is needed is hitting an endpoint from your client with client identification, email address and email details.I'm offering the first 100 startups \ projects 100 emails for free, after that it's a monthly subscription per usage. Feel free to register in the link and \ or ask me more about it :)
