WP Mail SMTP replaces WordPress.com's default outgoing mail with a direct, authenticated connection to your Titan mailbox — so contact-form replies, order confirmations, and other site notifications reliably reach your inbox instead of landing in spam or failing silently. This article is for Titan users who run a WordPress.com site and want their site's outgoing email to send through their Titan mail server. By the end, your site will send email using your own domain address, and you'll know how to confirm it's working.

Troubleshooting
Before you start
Check the following before you begin setup:
Third-party email access must be enabled on your Titan account. Learn how to enable it.
You'll need the email address and password for the Titan mailbox you want your site to send from. This address must be on the same domain as your WordPress.com site.
If your account is registered through Heart Internet, use Send email using Post SMTP plugin (Heart Internet users) instead — the setup steps are different for Heart Internet accounts.

Install and activate the plugin
-
In your WordPress.com dashboard, go to Plugins and install and activate WP Mail SMTP. You'll see WP Mail SMTP listed as Active in your Plugins list.
Configure the plugin settings
In your WordPress.com dashboard, click Settings.
Click WP Mail SMTP.
In the From Email field, enter the Titan email address you want your site to send from (for example, admin@yourdomain.com).
This address must match your WordPress.com admin email settings and must use your own domain — not a free email address like Gmail or Yahoo.
Optional: Check Force From Email if you want every plugin on your site to send using this address. This overrides the from-address settings of any other plugin.
In the Mailer section, select Other SMTP.
Enter your Titan server settings
With Other SMTP selected, enter the following values exactly.
| alert-warning | If you're hosted through Blacknight, MonoVM, DomainDiscount24, Fluccs, or Domain Central, follow this guide instead. |
| Option | Setting |
|---|---|
| SMTP Host | smtp.titan.email |
| Encryption | SSL |
| SMTP Port | 465 |
| Authentication | Set to ON. |
| SMTP Username | The same address you entered in From Email above (for example, admin@yourdomain.com) |
| SMTP Password | The password for that Titan mailbox |
Click Save Settings.
Confirm it's working
Once your settings are saved, send a test email from your WordPress.com site (for example, submit your own contact form) and confirm it arrives in your inbox within a few minutes. If it doesn't arrive, check the Troubleshooting section below.
| alert-warning | Always use an email address on the same domain as your WordPress.com site in the From Email field — mismatched domains are the most common reason delivery fails after setup. |
Troubleshooting
Emails still aren't arriving after setup
Cause: The address in From Email doesn't match the SMTP Username, or it isn't on your own domain.
Fix: Make sure both fields use the exact same Titan address, and that the address belongs to your site's domain.
You see an authentication error when sending
Cause: Third-party email access isn't enabled on your Titan account, or the password entered is incorrect.
Fix: Enable third-party email access, then re-enter your password in SMTP Password and save again.
