Email testing and debugging has never been easier.

HELO is a desktop app for macOS, Windows, and Linux which listens for outgoing emails of your local applications and catches them.

The swiss-army-knife of email testing and debugging.

Broken Link Checker

The automated link check verifies that all links in an email are valid and return an HTTP 200 status code. Don't send emails with broken links again.

Spam Report

If activated, HELO automatically checks the Apache SpamAssassin score of your incoming emails. Never lose a mail in your users spam box again.

Sharing

Share multiple emails with all the information that you see in HELO. Test all emails of your application, and share them with your client easily.

Remote Mailboxes

HELO allows you to create publicly available email
addresses. Send any email to those addresses,
and they will appear inside the HELO app.

A completely
refreshing
new way to test email.

Catch local emails

HELO exposes an SMTP server and catches the outgoing emails from your application instead of sending them to their actual recipient.

Unlimited Inboxes

Receive emails in a dedicated inbox per application by setting a unique name per project. There is no limit on the number of inboxes.

Simple content Review

HTML representation, text, source code, raw, headers–we got you covered. Check your emails before you deploy to production.

View Inspector

Install our open-source helper package to debug Laravel views or create own helpers to debug mails of your favorite framework.

Link Checker

The automated link check verifies that all links in an email are valid and return an HTTP 200 status code. Don't send emails with broken links again.

Spam Report

If activated, HELO automatically checks the Apache SpamAssassin score of your incoming emails. Never lose a mail in your users spam box again.

Forward Emails

Forward emails from HELO to team mates or clients for review. Send them to a testing service to see how they look in different email clients.

This feature requires HELO Cloud

Share Emails and Inboxes

Share multiple emails with all the information that you see in HELO. Test all emails of your application, and share them with your clients and colleagues easily.
