Submission Inbox – Forms & Email Log

Description

Submission Inbox helps WordPress site owners save form submissions, review leads, and understand what happened to related notification emails.

Many WordPress contact forms rely only on email notifications. If a notification email fails, is blocked, is misconfigured, or is never generated, the website owner may lose the enquiry without knowing it. Submission Inbox helps reduce that risk by storing form submissions inside your WordPress dashboard and connecting them with related WordPress email events.

Use built-in lead forms, or keep using supported form plugins such as Contact Form 7, WPForms, Fluent Forms, Forminator, and Ninja Forms.

Save leads even when email notifications fail

A visitor can submit a contact form, but the notification email might not arrive.

This can happen because of SMTP issues, incorrect sender settings, hosting mail restrictions, plugin conflicts, spam filtering, or a form that did not generate an email event.

Submission Inbox is built around a simple idea: the form submission should still be saved in WordPress, so the lead is not lost just because the email notification failed.

What you can do with Submission Inbox

Submission Inbox gives you a practical lead inbox and email status view inside WordPress.

You can:

  • Save form submissions in the WordPress admin dashboard.
  • Review leads without relying only on email notifications.
  • View submitted fields and lead details.
  • Filter and search saved submissions.
  • Export leads to CSV.
  • Create simple built-in lead forms.
  • Publish built-in forms with shortcodes.
  • Capture submissions from supported form plugins.
  • Review WordPress email events in the Email Log.
  • Check failed, missing, or unknown notification email status.
  • Configure SMTP sending for WordPress notification emails.
  • Create visitor auto-reply templates.
  • Assign auto-replies to specific forms and visitor email fields.
  • Protect built-in forms with Google reCAPTCHA v3.
  • Configure retention and privacy settings.

Built-in lead forms

Submission Inbox includes simple built-in forms for common lead capture use cases.

You can create a form, configure its fields, copy the shortcode, and place it on a page. Submissions are saved in the Inbox, and related notification email activity can be reviewed from the email status screens.

Built-in forms are useful when you need a simple contact form, enquiry form, callback request, service request, or basic lead capture form without installing a larger form builder.

Works with popular form plugins

You do not have to replace your existing form plugin.

Submission Inbox can capture submissions from supported form plugins and show them in one lead inbox.

Supported integrations include:

  • Contact Form 7
  • WPForms
  • Fluent Forms
  • Forminator
  • Ninja Forms

When a supported integration is enabled and the related form plugin is active, Submission Inbox can store captured submissions and help you review related email activity.

Email Log for WordPress emails

Submission Inbox includes an Email Log for WordPress email events.

This helps site owners and admins understand whether WordPress attempted to send a related notification email and whether the sending attempt failed.

The Email Log is useful for checking form notifications, WordPress system emails, and other email events generated through WordPress.

Email Status dashboard

The Email Status dashboard helps explain what happened after a form submission.

Instead of only showing raw technical errors, Submission Inbox helps group email activity into clearer statuses, such as:

  • Sent by WordPress
  • Failed
  • No email generated
  • Unknown

This makes it easier to find leads where the submission was saved, but the related notification email may not have worked as expected.

SMTP sending settings

Submission Inbox includes SMTP settings for WordPress notification emails.

You can configure:

  • SMTP host
  • Port
  • Encryption
  • Authentication
  • Username
  • Password
  • From email
  • From name

Using SMTP can help avoid common hosting mail issues where WordPress tries to send email through the default PHP mail function.

Submission Inbox logs email events and sending attempts, but it does not guarantee inbox delivery.

Visitor auto-replies

Submission Inbox includes visitor auto-reply templates and rules.

You can create reusable auto-reply templates and connect them to specific forms and visitor email fields.

This is useful when you want visitors to receive a confirmation email after submitting a form, while still keeping the original lead saved in your WordPress dashboard.

Google reCAPTCHA v3 for built-in forms

Built-in forms can be protected with Google reCAPTCHA v3.

This helps reduce automated spam submissions while keeping the form experience simple for real visitors.

Best for

Submission Inbox is useful for:

  • Small business websites that rely on contact forms.
  • Agencies managing client websites.
  • Site owners who do not want to lose enquiries.
  • WordPress admins who need saved form submissions.
  • Freelancers who want a simple lead inbox for client sites.
  • Websites that need basic form storage without a full CRM.
  • Sites where email notification problems need to be easier to review.

Why this matters

A contact form is often one of the most important parts of a business website.

If a visitor submits a form and the email notification fails, the website owner may never know that someone tried to get in touch.

Submission Inbox helps by saving the submission first, then giving you tools to review the lead and check the related email status.

This makes form submissions easier to manage, easier to export, and safer than relying only on email notifications.

Privacy and data control

Submission Inbox stores form submissions inside your WordPress database.

You control your own data from your WordPress admin area. The plugin also includes CSV export, retention, and privacy settings to help manage saved submissions responsibly.

What Submission Inbox does not do

Submission Inbox does not guarantee that an email reached the recipient’s inbox.

It also does not confirm whether a recipient opened or read an email.

The plugin logs WordPress email events and sending attempts, so you can see whether an email was generated, sent by WordPress, failed, or missing.

Summary

Submission Inbox is a practical WordPress lead inbox, form submission storage, and email log plugin.

It helps you save form submissions, review leads, check related email status, configure SMTP sending, create simple built-in forms, use visitor auto-replies, and capture submissions from popular form plugins.

If your website depends on contact forms, Submission Inbox helps make sure enquiries are easier to find, even when email notifications do not work as expected.
