When trying to use Gmail in smtpJS, I get the message "Only elasticemail is supported as an SMTP host". Is this a new rule or am I doing something wrong? It seems to have worked before. The code is same as in the documentation
as you can see now only Elastic Email is allowed as a reliable host with smtpjs so you have to create an account at first to use it. You can create a new account here and use a free trial of up to 100 emails/day. For more, you have to pay.
