All-In-One WP Mailer Plugin: background queue sending, mail open/click measurement, email address check, DNS setup, send emails 10x faster than SMTP
New approach to a WP Mail plugin – no need for SMTP!
As you may know, WordPress comes with only marginal functionality for sending email. Many emails sent simply end up in the recipient’s spam folder.
The usual way is to use a WP mail SMTP plugin to send email from WordPress through external SMPT services (like Mailchimp, Mailgun, SendGrid, SendInBlue, and other SMTP services). Those services usually offer a small free tier, but also may cost your money on an ongoing basis.
Campation PostOffice is unlike any other WP email plugin!
PostOffice intercepts the wp_mail() function (like other SMTP plugins) and forwards all emails to an outgoing background queue. Sending in the background no longer slows down your website while providing an accurate log of all emails.
But as long as your WordPress website is able to send emails without any plugin, PostOffice enhances this generic function through its own email sending technology, Campation SpeedMail, which is 10x faster than SMPT and free of costs! Of course, this plugin can connect you to any SMTP server, too – but that’s antiquated.
Addionally PostOffice comes with Campation SmartDNS to check and setup the DNS of your domain (A, MX, SPF, DMARC, DKIM etc.) easily with ‘copy & paste’! Only a correctly configured DNS helps to improve email deliverability and guarantees your emails to not end up in the recipient’s spam folder, regardless of the sending plugin used.
Take advantage of even more unique features that are not found in other WP Mail plugins:
- Recipient address check: all recipient addresses are checked for correct spelling and MX record before sending emails – this can drastically reduce your bounce rate for WordPress email
- Recipient database: all contacted e-mail addresses are included in the recipient database inside your WP
- Outgoing mail queue: all emails are queued and processed in the background – you see the delivery/opening/click status of each email
- Digital signature of email: all emails are digitally signed and comply with the DKIM standard to avoid being marked as spam
- Open / Click measurement: open / click events in an email and the time elapsed since sending are measured
- Dashboard: Charts, graphs and statistics show how your emails are flowing from WordPress
- 24h statistical data: emails sent, opened, clicked, bounced, unsubscribed – compared to min/max target values you set for your outgoing email
- Setup Wizard: simplified configuration to get this plugin up and running to send email in just a few steps
- Permanent blindcopy (BCC): optional bcc of all transactional email (e.g. invoices) to the WordPress admin
- Automatic cleanup of queue: Sent emails are deleted from the queue after a defined period of days to keep your WordPress database small
- integrated FAQ and support system: Clarify all your questions and technical problems directly within the plugin administration
Campation PostOffice is a next generation, SMTP account independant WP Mail plugin, professionally coded using latest software technologies. It features a modern, fully AJAX-driven user interface, is fully compatibel with latest PHP 8.1.5 and coming WordPress 6.

Will I need an SMPT service?
No. Campation PostOffice uses proprietary email sending technology (SpeedMail™) that is 10 times faster than WordPress mail with SMTP. Your data is not sent to external services and there are no costs for external SMTP service providers! Nevertheless, you can use SMTP!
Why is it so much faster than any WP Mail SMTP plugin?
Put simply: it doesn’t need to connect and communicate through the SMTP protocol! To send your mails via an external SMTP server, your WordPress server must contact it. The two servers then start a typical SMTP dialog with about 10 questions and answers (“Who is there?”, “Who is the email going to?” etc.). This adds up to a time requirement of 700 – 1,200 milliseconds for each email. Therefore, on average, an WP mail plugin with SMTP can only send around 1 email per second – while SpeedMail can send 10-20 emails per second.
Will this plugin slow down my public website?
no way! All WordPress emails are stored in a queue (takes a few milliseconds) and sent in the background – your website won’t falter anymore! All recipient addresses are checked before use and permanently blocked in the event of errors.
How difficult is the configuration?
Once activated, you will be guided by an intuitive setup wizard to make all settings. Thanks to our SmartDNS™ technology, you can configure your domain’s DNS perfectly in no time at all – send email just like the big ones!
Can I also use PostOffice if my WordPress only allows to send emails via SMTP?
Of course! The only thing that cannot be used is the fast sending method Speedmail, but all other functions are also available for SMTP
Which SMTP services does the plugin support?
It supports any SMTP service (like Gmail, SendGrid, MailGun, Amazon SES, Mandrill, Yahoo etc.) but not through their API. But: there is no need for any SMTP connection!
