The problem
Why WordPress emails never arrive
By default WordPress uses the server’s mail() function. Without authenticated SMTP and aligned DNS records, notifications, forms and password resets land in spam — or never leave.
-
Unauthenticated sending
Without dedicated SMTP, many providers reject or filter messages generated by the CMS.
-
Incomplete DNS
Missing SPF, DKIM or DMARC means mail clients don’t trust the sender and push everything to spam.
-
No visibility
When a send fails, there’s often no useful trail left — hard to tell if it’s SMTP, DNS or the form plugin.
Everything you need for deliverability

Telemetry only if you turn it on
Nothing is sent without explicit consent. You can disable telemetry anytime in the plugin settings.
If consent is active, we may receive
- site domain and URL
- plugin, WordPress and PHP versions
- site language
- user type (if provided)
- timestamps of plugin lifecycle events
We never send
- SMTP credentials
- admin email addresses
- email contents
- site contents

Frequently asked questions
Does FastSMTP store email content?
No. The log keeps only technical send metadata, never the message body.
Can I disable telemetry?
Yes, anytime in the settings. Telemetry is opt-in: nothing is sent without explicit consent.
Does it work with plugins that use wp_mail?
Yes. FastSMTP intercepts the wp_mail/PHPMailer flow and applies your saved SMTP configuration.
Is FastSMTP free?
Yes. It is free on the WordPress repository: hostit-fastsmtp.
What are the requirements?
WordPress 6.0 or higher and PHP 7.4 or higher. Tested with recent WordPress releases.
Do I have to use Host.it SMTP?
