Know how WordPress is trying to send

Email problems are much easier to fix when the transport and evidence are in one place.

WordPress plugins normally send through wp_mail(), but the final delivery route depends on the site and provider configuration. Regal Send keeps that WordPress mail workflow intact while letting you choose a supported transport, standardise sender details, test the active configuration and retain the right level of evidence for troubleshooting.

1

Choose the right transport

Use Default / PHP, Other SMTP, Elastic Email, Brevo, SendGrid, Zoho Mail, Amazon SES, SendLayer, SMTP.com, Google / Gmail or Microsoft 365 / Outlook.

2

Diagnose failures with evidence

Send diagnostic messages, review redacted provider results and inspect retained email logs instead of troubleshooting from guesswork alone.

3

Track delivery and engagement

Review retained send attempts and failures, track email opens and link clicks, filter reports by date and optionally email scheduled summaries to administrators.

Core features

The practical tools behind Regal Send.

Eleven mailer choices

Default / PHP, Other SMTP, Elastic Email, Brevo, SendGrid, Zoho Mail, Amazon SES, SendLayer, SMTP.com, Google / Gmail and Microsoft 365 / Outlook.

Secure credentials

Saved SMTP passwords, API keys, OAuth client secrets and tokens are protected rather than rendered back into the settings screen.

Sender controls

Optional forced From Email, From Name and Return-Path settings for a consistent site identity.

Email logs

Off, Metadata Only and Full Logging modes with filters, log details, CSV export and configurable retention.

Test & resend tools

Diagnostic test email plus explicit review and resend for eligible Full Logging records using the currently active mailer.

Reports & privacy tools

Date-bounded reports, scheduled email summaries, failure alerts and integration with WordPress personal-data export and erasure workflows.

Email open tracking

Record open activity for tracked messages and review it alongside the retained email record.

Link click tracking

Record clicks on tracked links so email engagement can be reviewed alongside send status, logs and reports.

Try it on your site

Give WordPress email a defined transport, engagement tracking and a better troubleshooting trail.

Use the 7-day trial to configure a real mailer, send a diagnostic message and see how Regal Send records transport results, opens and clicks on your site.
