OrangeSMTP replaces WordPress’s default mail function with a reliable SMTP connection, ensuring your emails actually reach the inbox — not the spam folder.
Whether you’re running a WooCommerce store, a membership site, or a business blog, OrangeSMTP gives you complete control over how your WordPress emails are sent, tracked, and monitored.
<h3>Why WordPress Emails Fail</h3>
By default, WordPress sends emails using the PHP <code>mail()</code> function, which has no authentication. Most email providers reject or silently drop these messages. OrangeSMTP routes your emails through a trusted SMTP provider with proper authentication, so your messages are delivered reliably every time.
<h3>12+ Email Providers Supported</h3>
Connect to the provider that works best for you:
<ul>
<li>Gmail / Google Workspace — Send using your Google account with App Password or OAuth</li>
<li>Mailgun — API + SMTP with open & click tracking</li>
<li>Amazon SES — High-volume sending with AWS reliability</li>
<li>SendGrid — Industry-leading deliverability</li>
<li>Brevo (formerly Sendinblue) — Free tier with generous limits</li>
<li>Zoho Mail — Ideal for Zoho Workspace users</li>
<li>Postmark — Built for transactional email</li>
<li>SparkPost — Enterprise-grade delivery</li>
<li>SMTP.com — Dedicated SMTP infrastructure</li>
<li>Resend — Modern API-first email service</li>
<li>MailerSend — Transactional email with templates</li>
<li>Generic SMTP — Any provider: Yahoo, Outlook, Hotmail, and more</li>
</ul>
<h3>Failure Alert Channels</h3>
Get instantly notified the moment an email fails to deliver — before your customers notice:
<ul>
<li>📧 Email — Alert sent to any address</li>
<li>💬 Slack — Post to any Slack channel</li>
<li>🎮 Discord — Send to a Discord webhook</li>
<li>📱 Telegram — Message via Telegram bot</li>
<li>🔷 Microsoft Teams — Post to a Teams channel</li>
<li>🔗 Custom Webhook — Connect to Zapier, Make, n8n, or any HTTP endpoint</li>
</ul>
Each channel can be enabled, disabled, and tested independently from the Failure Alerts page.
<h3>Email Log & Tracking</h3>
Every outgoing email is logged with full delivery details:
<ul>
<li>Sent / failed status</li>
<li>Provider used</li>
<li>Delivery timestamp</li>
<li>Open tracking</li>
<li>Click tracking</li>
<li>Error messages for failed emails</li>
</ul>
<h3>Email Template Builder</h3>
Design professional transactional emails with the built-in template editor:
<ul>
<li>Rich HTML editor with live preview</li>
<li>5 built-in starter templates</li>
<li>Custom templates with your own branding</li>
<li>Fallback plain-text generation</li>
</ul>
<h3>Routing & Failover</h3>
<ul>
<li>Smart Routing — Route emails to different providers based on from-address, subject keywords, email type, or source plugin</li>
<li>Failover / Circuit Breaker — Automatically switch to a backup provider when the primary fails; circuit reopens after 30 minutes</li>
</ul>
<h3>Setup Guides</h3>
Step-by-step setup guides are built into the plugin for every provider and every alert channel — no documentation tab switching needed.

The Superfast Mailgun add-on for the <a href="https://wordpress.org/plugins/newsletter/" rel="ugc">Newsletter</a> plugin allows you to take full advantage of the Mailgun “Batch Send” API. This makes it possible to send a newsletter to up to 1,000 addresses in a single API call.
For 10,000 subscribers, that’s 10 API calls instead of 10,000 calls. Quite a difference. It will take a lot less time to send out your newsletter.
<ul>
<li>
Sends newsletters to up to 1,200 subscribers per hour.
</li>
<li>
Polls Mailgun for “bounces” and updates your mailing list accordingly.
</li>
<li>
Support by email or through the forum on wordpress.org
</li>
</ul>
Note: 
Filters ‘newsletter_message_html’, ‘newsletter_message_text’, ‘newsletter_message_subject’ and ‘newsletter_message’ are called only once per email, and receive a null $user parameter. This is because Mailgun takes care of replacing user-specific tags in the email. 
Note that the Newsletter plugin has deprecated filters ‘newsletter_message_html’, ‘newsletter_message_text’ and ‘newsletter_message_subject’ in favour of ‘newsletter_message’.When they are removed, this addon will stop using them as well.
<h3>Pro version</h3>
For mailing lists with more than 1,000 subscribers, get the <a href="http://howfrankdidit.com/superfast-newsletters-with-mailgun" rel="nofollow ugc">Pro version</a>!
<ul>
<li>
Sends up to 120,000 emails / hour
</li>
<li>
Integrated Open/Click statistics (Requires the Newsletter Statistics add-on)
</li>
<li>
Selectable polling frequency
</li>
<li>
Transactional emails (e.g. Welcome email, subscription confirmation) can use a different route, e.g. using a different domain
</li>
<li>
Priority email support
</li>
</ul>
You can easily upgrade from within your WordPress dashboard.
