Hope we all are doing great? I wish to announce the beta release of version
1.0 of the SendGrid MediaWiki extension which enables MediaWiki to send
emails using the SendGrid API. I have been working on this extension for
some time now and finished up the first version last night :).
It's very simple to use and all you need is a valid SendGrid API key
(config in your LocalSettings.php file "wgSendGridAPIKey") and you are
done. In addition, this can be used also by user doing development locally
and wish to send emails from their local wiki. SendGrid offers 12,000
emails to its users for an unlimited time and this can come in handy when
you are not in deployment / production environment.
I wish members of the development community to try this extension out and
see how it works and give in their feedback. A work board for this project
/ extension has been has been requested  and will be up soon, but the
extension is okay for use :).
Extensions that perform a similar role are; Mailgun & SwiftMailer. We
need more of this mailer extensions to have various varieties. :)
