Description
TechByIt SMTP sends WordPress site email through a configured SMTP server. It works with messages sent using WordPress’s wp_mail() function, including notifications from plugins that use that function.
From the TechByIt SMTP admin menu, you can configure your server, choose the active provider, set a default sender, and send a test email.
Features
- Custom SMTP configuration with host, port, encryption, authentication, and connection timeout settings.
- Default From name and email address settings.
- A test email form with success and error feedback.
- Encrypted storage for provider passwords and keys.
- Settings restricted to WordPress users with permission to manage site options.
Available providers
Custom SMTP is the only provider currently available for sending.
Configuration forms are also included for Gmail, Google Workspace, Microsoft 365, Amazon SES, SendGrid, Mailgun, Brevo, and Postmark. Their sending transports and OAuth connections are not available yet.
Message logging, dashboard statistics, retry, and resend are planned features. The Mail Logs page is currently a placeholder.

FAQ
-
Do I need an SMTP service?
-
Yes. To send through Custom SMTP, you need access to an SMTP server and its connection details. TechByIt SMTP does not provide an email account or SMTP service.
-
What happens when no provider is active?
-
WordPress keeps its usual mail behavior. TechByIt SMTP starts routing mail through Custom SMTP after you configure and activate that provider.
-
Can I connect Gmail, Microsoft 365, or an API provider?
-
Their dedicated configuration forms can save settings, but their sending transports are not implemented. Saving OAuth client credentials does not connect an account. Use Custom SMTP with a service that supplies compatible SMTP connection details.
-
Does a successful test guarantee inbox delivery?
-
No. Success means the SMTP server accepted the message. Check the recipient’s inbox and spam folder to confirm where the message arrived.
-
Can I view email logs or resend messages?
-
These features are not available in this version. The Mail Logs page is a placeholder.
-
Why are saved passwords not shown in the form?
-
Saved secrets are not displayed again. Leaving a saved password field blank keeps the existing value. Enter a new value to replace it. If your site’s WordPress salts change, enter the credentials again.
-
Where are the development instructions?
-
Install development dependencies with
composer installandpnpm install --frozen-lockfile. Runcomposer test,composer lint:php,pnpm test,pnpm typecheck,pnpm lint, andpnpm buildto check the project.
