<p>By default, WordPress uses PHP Mail to send its emails. If you are reading this, you probably know that this isn’t a perfect solution. Some hosting providers put a limit on the amount of emails that they can process, and there is no log’s or records of emails once they are sent.</p>
<p>This plugin automatically handles redirecting emails that are normally sent by WordPress to Mandrill instead. Headers, Attachments, Content Type .etc are all automatically handled. There is minimal setup involved. Simply add your Mandrill API Key and your ‘From Name’ and ‘EMail’ and your good to go.</p>


Primail

The Primail plugin allows you to connect your WordPress site with Mandrill for improved email delivery and reliability

<p>Connect SendGrid for Emails is a third-party fork of (and a drop-in replacement for) the official SendGrid plugin. This plugin is not endorsed by or affiliated with SendGrid. This plugin connects to an external service (the SendGrid API).</p>
<p>The Connect SendGrid for Emails plugin replaces WordPress’s default wp_mail() function by using either an SMTP or API integration with SendGrid to send outgoing email from your WordPress installation. It also allows you to upload contacts directly to your SendGrid Marketing Campaigns account via a subscription widget.</p>
<p>By using the Connect SendGrid for Emails plugin, you will be able to take advantage of improved deliverability and an expanded feature set, including tracking and analytics, to enhance user engagement on your WordPress installation.</p>
<h4>The Subscription Widget</h4>
<p>The WordPress Subscription Widget makes it easy for people visiting your WordPress site to subscribe to your marketing emails, such as any newsletters, announcements, or promotional offers you may send. Upon signup, they’ll automatically receive an opt-in email allowing them to confirm their desire to begin receiving your emails. This confirmation constitutes “double opt-in,” a deliverability best practice.</p>
<h4>Multisite</h4>
<p>If you are using the Connect SendGrid for Emails plugin in a Multisite environment, you need to Network Activate it. You can then access the settings page on the network dashboard and the configure settings will be used for all sites.</p>
<p>You can enable access for SendGrid settings to each subsite in the Multisite Settings tab. If the checkbox is unchecked then that site will not see the SendGrid settings page and it will use the settings set on the network.<br />
Warning! When you activate SendGrid management for a subsite, that site will not be able to send emails until the admin updates the SendGrid settings on that subsite.</p>
<p>If you already had the plugin installed in a Multisite environment and you update to versions after 1.9.0 you may need to reconfigure your plugin.</p>


Connect SendGrid for Emails


I spent long hours looking for a solution to send emails on my restricted hosting account. Out of despair, I tried all the plugins in the repository that modified the wp_mail() function (incl. plugins with millions of installations) but none of the commercial plugins out there come even closer to what this simple but effective plugin provides! I was able to connect to sendgrid for seconds, just adding api key and sender's address. Plugin supports multisite (free versions of other commercial plugins lacking this) and had all the options I needed, e.g. not showing the plugin settings on a single instance.
