Need to config mail in Admin -> Settings -> Email.
Support Mailgun, SendGrid, SES, Gmail, Sendmail... and other SMTP mail services. We suggest use Mailgun to send mail.
Make sure that you have saved settings (button Save settings at the bottom of page) before sending a test email.
Example:
SMTP
smtp.gmail.com
tls
[your-gmail]
[password-app]
(docs: https://support.google.com/mail/answer/185833?hl=en-GB)Example:
The secret key must have a prefix key-
. Ex: key-xxxxx
.
Example:
smtp.sendgrid.net
apikey
