Smmooth WP Plugins

Smooth SMTP gives you full control over how WordPress sends email. Configure SMTP as your primary sending method, set up a fallback for when things go wrong, get notified through your preferred channels, and keep a detailed log of every email your site sends.
Primary Sending Method (SMTP)
Configure any SMTP provider as your primary sending method. If you leave SMTP disabled, WordPress will continue using its default PHP mail — either way, all other features still work.
<ul>
<li>Works with any SMTP provider: Gmail, SendGrid, Amazon SES, Mailgun, and more</li>
<li>Configurable host, port, encryption (SSL/TLS), username, password, from email, and from name</li>
<li>Secure credential storage using WordPress’s built-in options API</li>
</ul>
Fallback Sending Method
If the primary sending method fails, Smooth SMTP can automatically retry using a fallback. This works regardless of whether you’re using SMTP or WordPress’s default PHP mail as your primary.
<ul>
<li>Fallback to WordPress Default (PHP mail) or a second SMTP server</li>
<li>Full credential configuration for the fallback SMTP</li>
<li>Logged separately so you can see exactly which method delivered each email</li>
</ul>
Failure Alert Channels
Get notified the moment an email fails — through the channels your team already uses.
<ul>
<li>Slack, Discord</li>
<li>Telegram (via Bot API — requires bot token and chat ID)</li>
<li>WhatsApp (via CallMeBot webhook)</li>
<li>SMS or any custom webhook endpoint</li>
<li>Add multiple channels, enable/disable each independently</li>
<li>Send Test Alert button per channel</li>
<li>Alerts are throttled to at most one per 60 seconds to avoid flooding</li>
</ul>
Email Summary Reports
Receive a periodic HTML email summarising your site’s email activity.
<ul>
<li>Hourly, daily, weekly, or monthly schedule</li>
<li>Total sent and failed counts, breakdown by sending method, and recent failures</li>
<li>Configurable recipient address</li>
<li>Send Summary Now button for an instant preview</li>
</ul>
Email Logging
Every email your site sends is logged with full detail.
<ul>
<li>Status (success / failed), sender, recipients, subject, message body</li>
<li>Sent Via column showing which method delivered the email (Primary SMTP, Fallback SMTP, Fallback WordPress Default, etc.)</li>
<li>Search, filter, and paginate logs from the admin dashboard</li>
<li>View full email detail in a modal</li>
<li>Bulk delete, bulk resend, and delete-all options</li>
<li>Admin dashboard notice when the most recent email failed</li>
</ul>
Dashboard
A at-a-glance overview of your site’s email activity.
<ul>
<li>Total sent, failed, and success rate stat cards</li>
<li>Breakdown by sending method with progress bars</li>
<li>Recent failures table</li>
<li>Filter by day, week, month, or all time</li>
</ul>
Test Email
Send a test email at any time to verify your configuration.
<ul>
<li>Choose which sending method to test — primary or fallback — independently</li>
<li>Send plain text or HTML test emails</li>
<li>Specify any recipient address</li>
<li>Always available regardless of whether SMTP is configured</li>
</ul>
Other
<ul>
<li>One-click import of email logs from Post SMTP</li>
<li>Option to keep logs and settings when the plugin is deleted</li>
<li>Compatible with Post SMTP and WP Mail SMTP (Smooth SMTP acts as a fallback when another SMTP plugin is detected)</li>
</ul>
<h3>Privacy Policy</h3>
This plugin logs email metadata including sender address, recipient addresses, subject line, message body, and sending status. SMTP credentials are stored in your WordPress database. No data is transmitted to external services except through the alert channels and SMTP servers you explicitly configure.

Did you find this plugin helpful? Please consider <a href="https://wordpress.org/support/view/plugin-reviews/send-emails-with-mandrill/" rel="ugc">leaving a 5-star review</a>.
Note: This is a forked version of the now unsupported <a href="https://wordpress.org/plugins/wpmandrill/" rel="ugc">wpMandrill</a> plugin. The notes below are copied over from the original plugin and will be updated as relevant updates become available. Please help by contributing to the GitHub repository <a href="https://github.com/Miller-Media/send-emails-with-mandrill" rel="nofollow ugc">Send Emails With Mandrill on GitHub</a>
This plugin uses <a href="http://mandrillapp.com/api/docs/" rel="nofollow ugc">Mandrill API</a> to send outgoing emails, with or without attachments, from your WordPress installation. It replaces the wp_mail function included with WordPress.
Emails are tracked and automatically tagged for statistics within the Mandrill Dashboard. You can also add general tags to every email sent, as well as particular tags based on selected emails defined by your requirements.
You can also use your own templates that have been added to your MailChimp account and shared with your Mandrill account.
There are a few levels of integrations between your WordPress installation and this plugin:
<ol>
<li>The simplest option: Install it, configure it, and Send Emails with Mandrill will start sending your emails through Mandrill.</li>
<li>If you need to fine tune certain emails, you can change any email by creating a filter for the mandrill_payload hook.</li>
<li>For further customization, we’ve exposed a function that allows you to send emails from within your plugins, instead of the regular wp_mail function: wpMandrill::mail</li>
</ol>
Enable the connection by entering a valid API key in the settings page or adding the line <code>define('SEWM_API_KEY', '{YOUR_API_KEY}')</code> your site’s wp-config.php file.
Spanish translation available.

Send Emails with Mandrill

This was a super useful plugin that Mandrill/MailChimp stopped supporting, so glad to see it being actively supported again!

Great to see this plugin revived!

Really good. Thank you.

Thank you for taking the initiative to fork the unsupported plugin and get it working with modern PHP.

Thank you for supporting the plugin

Great that this plugin got a second life! It beats tons of other SMTP plugins trying to support mandrill. It needs a few updates to be fully PHP7.4 compatible and it would be great to have a few extra options (thing return_path_domain etc). On that note: I can help if that would in this great effort!?

Thanks, can I help ?


I am very happy with it, using it on 150 sites.


Great plugin

'Send Emails with Mandrill' sends emails that are generated by WordPress through Mandrill, a transactional email service powered by MailChimp.
