It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://ps.w.org/wp-mail-smtp-sendgrid-edition/assets/icon.svg?rev=1899243) # WP Mail SMTP SendGrid Edition By [FolioVision](https://profiles.wordpress.org/foliovision/) [Download](https://downloads.wordpress.org/plugin/wp-mail-smtp-sendgrid-edition.zip) * [Details](https://srd.wordpress.org/plugins/wp-mail-smtp-sendgrid-edition/#description) * [Reviews](https://srd.wordpress.org/plugins/wp-mail-smtp-sendgrid-edition/#reviews) * [Installation](https://srd.wordpress.org/plugins/wp-mail-smtp-sendgrid-edition/#installation) * [Development](https://srd.wordpress.org/plugins/wp-mail-smtp-sendgrid-edition/#developers) [Support](https://wordpress.org/support/plugin/wp-mail-smtp-sendgrid-edition/) ## Description This plugin reconfigures the wp_mail() function to use SMTP instead of mail() and creates an options page that allows you to specify various options. You can set the following options: * Specify the from name and email address for outgoing email. * Choose to send mail by SMTP or PHP’s mail() function. * Specify an SMTP host (defaults to localhost). * Specify an SMTP port (defaults to 25). * Choose SSL / TLS encryption (not the same as STARTTLS). * Choose to use SMTP authentication or not (defaults to not). * Specify an SMTP username and password. Also adds subject to headers for SendGrid Activity Screen. SengGrid is a powerful SMTP service, however it’s Activity Log screen misses the message subjects. Our plugin adds that back in! ## Screenshots [⌊Advanced Email Options⌉⌊Advanced Email Options⌉[ Advanced Email Options [⌊SMTP Options⌉⌊SMTP Options⌉[ SMTP Options [⌊Send a Test Email⌉⌊Send a Test Email⌉[ Send a Test Email [⌊Subject in the SendGrid Activity screen⌉⌊Subject in the SendGrid Activity screen⌉[ Subject in the SendGrid Activity screen ## Installation 1. Download 2. Upload to your `/wp-contents/plugins/` directory. 3. Activate the plugin through the ‘Plugins’ menu in WordPress. ## FAQ ### My plugin still sends mail via the mail() function If other plugins you’re using are not coded to use the wp_mail() function but instead call PHP’s mail() function directly, they will bypass the settings of this plugin. Normally, you can edit the other plugins and simply replace the `mail(` calls with` wp_mail(` (just adding wp_ in front) and this will work. I’ve tested this on a couple of plugins and it works, but it may not work on all plugins. ### Will this plugin work with WordPress versions less than 2.7? No. WordPress 2.7 changed the way options were updated, so the options page will only work on 2.7 or later. ### Can I use this plugin to send email via Gmail / Google Apps Yes. Use these settings: Mailer: SMTP SMTP Host: smtp.gmail.com SMTP Port: 465 Encryption: SSL Authentication: Yes Username: your full gmail address Password: your mail password ## Reviews There are no reviews for this plugin. ## Contributors & Developers “WP Mail SMTP SendGrid Edition” is open source software.
